1.从Spring boot官网根据需求下载脚手架或者到GitHub上去搜索对应的脚手架项目,D_iao ^0^
• 文件目录如下(此处generatorConfig.xml 和 log4j2.xml文件请忽略,后续会讲解)
2.使用Mybatis代码自动构建插件生成代码
• gradle 相关配置
// Mybatis 代码自动生成所引入的包
compile group: 'org.mybatis.generator', name: 'mybatis-generator-core', version: '1.3.3'
// MyBatis代码自动生成插件工具
apply plugin: "com.arenagod.gradle.MybatisGenerator"
configurations {
mybatisGenerator
}
mybatisGenerator {
verbose = true
// 配置文件路径
configFile = 'src/main/resources/generatorConfig.xml'
}

<!--生成的model 包路径 ,其中rootClass为model的基类,配置之后他会自动继承该类作为基类,trimStrings会为model字串去空格-->
<javaModelGenerator targetPackage="com.springboot.mybatis.demo.model"

<!-- 对应的表 这个是生成Mapper xml文件的基础,enableCountByExample如果为true则会在xml文件中生成样例,过于累赘所以不要-->
<table tableName="tb_user" domainObjectName="User"

enableDeleteByExample="false"
enableSelectByExample="false"
enableUpdateByExample="false"></table>
</context>
</generatorConfiguration>
以上配置中注意targetProject路径请填写绝对路径,避免错误,其中targetPackage是类所处的包路径(确保包是存在的,否则无法生成),也就相当于
• 代码生成
配置完成之后首先得在数据库中新建对应的表,然后确保数据库能正常访问,最后在终端执行gradle mbGenerator或者点击如下任务
成功之后它会生成model、mapper接口以及xml文件
3.集成日志
• gradle 相关配置
compile group: 'org.springframework.boot', name: 'spring-boot-starter-log4j2', version: '1.4.0.RELEASE'
// 排除冲突
configurations {
mybatisGenerator
compile.exclude module: 'spring-boot-starter-logging'
}
当没有引入spring-boot-starter-log4j2包时会报错:java.lang.IllegalStateException: Logback configuration error detected Logback 配置错误声明
原因参考链接;https://blog.csdn.net/blueheart20/article/details/78111350?locationNum=5&fps=1
解决方案:排除依赖 spring-boot-starter-logging
what???
排除依赖之后使用的时候又报错:Failed to load class "org.slf4j.impl.StaticLoggerBinder" 加载slf4j.impl.StaticLoggerBinder类失败
原因参考链接:https://blog.csdn.net/lwj_199011/article/details/51853110
解决方案:添加依赖 spring-boot-starter-log4j2 此包所依赖的包如下:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</dependency>
</dependencies>
</project>
它依赖了 log4j-slf4j-impl ,使用的是log4j2日志框架。
这里涉及到log4j、logback、log4j2以及slf4j相关概念,那么它们是啥关系呢?unbelievable...相关知识如下:
slf4j、log4j、logback、log4j2
日志接口(slf4j)
slf4j是对所有日志框架制定的一种规范、标准、接口,并不是一个框架的具体的实现,因为接口并不能独立使用,需要和具体的日志框架实现配合使用(如log4j、logback)
日志实现(log4j、logback、log4j2)
log4j是apache实现的一个开源日志组件
logback同样是由log4j的作者设计完成的,拥有更好的特性,用来取代log4j的一个日志框架,是slf4j的原生实现
Log4j2是log4j 1.x和logback的改进版,据说采用了一些新技术(无锁异步、等等),使得日志的吞吐量、性能比log4j 1.x提高10倍,并解决了一些死锁的bug,而且配置更加简单灵活,官网地址: http://logging.apache.org/log4j/2.x/manual/configuration.html
为什么需要日志接口,直接使用具体的实现不就行了吗?
接口用于定制规范,可以有多个实现,使用时是面向接口的(导入的包都是slf4j的包而不是具体某个日志框架中的包),即直接和接口交互,不直接使用实现,所以可以任意的更换实现而不用更改代码中的日志相关代码。
比如:slf4j定义了一套日志接口,项目中使用的日志框架是logback,开发中调用的所有接口都是slf4j的,不直接使用logback,调用是 自己的工程调用slf4j的接口,slf4j的接口去调用logback的实现,可以看到整个过程应用程序并没有直接使用logback,当项目需要更换更加优秀的日志框架时(如log4j2)只需要引入Log4j2的jar和Log4j2对应的配置文件即可,完全不用更改Java代码中的日志相关的代码logger.info(“xxx”),也不用修改日志相关的类的导入的包(import org.slf4j.Logger;
import org.slf4j.LoggerFactory;)
使用日志接口便于更换为其他日志框架,适配器作用
log4j、logback、log4j2都是一种日志具体实现框架,所以既可以单独使用也可以结合slf4j一起搭配使用)
• 到此我们使用的是Log4j2日志框架,接下来是配置log4j,具体配置详解如下:
<?xml version="1.0" encoding="UTF-8"?>
<!--日志级别以及优先级排序: OFF > FATAL > ERROR > WARN > INFO > DEBUG > TRACE > ALL -->
<!--Configuration后面的status,这个用于设置log4j2自身内部的信息输出,可以不设置,当设置成trace时,你会看到log4j2内部各种详细输出-->
<!--monitorInterval:Log4j能够自动检测修改配置 文件和重新配置本身,设置间隔秒数-->
<Configuration status="WARN">
<!--定义一些属性-->
<Properties>
<Property name="PID">????</Property>
<Property name="LOG_PATTERN">
[%d{yyyy-MM-dd HH:mm:ss.SSS}] - ${sys:PID} --- %c{1}: %m%n
</Property>
</Properties>
<!--输出源,用于定义日志输出的地方-->
<Appenders>
<!--输出到控制台-->
<Console name="Console" target="SYSTEM_OUT" follow="true">
<PatternLayout
pattern="${LOG_PATTERN}">
</PatternLayout>
</Console>
<!--文件会打印出所有信息,这个log每次运行程序会自动清空,由append属性决定,适合临时测试用-->
<!--append为TRUE表示消息增加到指定文件中,false表示消息覆盖指定的文件内容,默认值是true-->
<!--<File name="File" fileName="logs/log.log" append="false">-->
<!--<PatternLayout>-->
<!--<pattern>[%-5p] %d %c - %m%n</pattern>-->
<!--</PatternLayout>-->
<!--</File>-->
<!--这个会打印出所有的信息,每次大小超过size,则这size大小的日志会自动存入按年份-月份建立的文件夹下面并进行压缩,作为存档 -->
<RollingFile name="RollingAllFile" fileName="logs/all/all.log"
filePattern="logs/all/$${date:yyyy-MM}/all-%d{yyyy-MM-dd}-%i.log.gz">
<PatternLayout
pattern="${LOG_PATTERN}" />
<Policies>
<!--以下两个属性结合filePattern使用,完成周期性的log文件封存工作-->
<!--TimeBasedTriggeringPolicy 基于时间的触发策略,以下是它的两个参数:
1.interval,integer型,指定两次封存动作之间的时间间隔。单位:以日志的命名精度来确定单位,比如yyyy-MM-dd-HH 单位为小时,yyyy-MM-dd-HH-mm 单位为分钟
2.modulate,boolean型,说明是否对封存时间进行调制。若modulate=true,则封存时间将以0点为边界进行偏移计算。比如,modulate=true,interval=4hours,那么假设上次封存日志的时间为03:00,则下次封存日志的时间为04:00,之后的封存时间依次为08:00,12:00,16:00-->
<!--<TimeBasedTriggeringPolicy/>-->
<!--SizeBasedTriggeringPolicy 基于日志文件大小的触发策略,以下配置解释为:
当单个文件达到20M后,会自动将以前的内容,先创建类似 2014-09(年-月)的目录,然后按 "xxx-年-月-日-序号"命名,打成压缩包-->
<SizeBasedTriggeringPolicy size="200 MB"/>
</Policies>
</RollingFile>
<!-- 添加过滤器ThresholdFilter,可以有选择的输出某个级别及以上的类别 onMatch="ACCEPT" onMismatch="DENY"意思是匹配就接受,否则直接拒绝 -->
<RollingFile name="RollingErrorFile" fileName="logs/error/error.log"
filePattern="logs/error/$${date:yyyy-MM}/%d{yyyy-MM-dd}-%i.log.gz">
<ThresholdFilter level="ERROR"/>
<PatternLayout
pattern="${LOG_PATTERN}" />
<Policies>
<!--<TimeBasedTriggeringPolicy/>-->
<SizeBasedTriggeringPolicy size="200 MB"/>
</Policies>
</RollingFile>
<RollingFile name="RollingWarnFile" fileName="logs/warn/warn.log"
filePattern="logs/warn/$${date:yyyy-MM}/%d{yyyy-MM-dd}-%i.log.gz">
<Filters>
<ThresholdFilter level="WARN"/>
<ThresholdFilter level="ERROR" onMatch="DENY" onMismatch="NEUTRAL"/>
</Filters>
<PatternLayout
pattern="${LOG_PATTERN}" />
<Policies>
<!--<TimeBasedTriggeringPolicy/>-->
<SizeBasedTriggeringPolicy size="200 MB"/>
</Policies>
</RollingFile>
</Appenders>
<!--然后定义Loggers,只有定义了Logger并引入的Appender,Appender才会生效-->
<Loggers>
<Logger name="org.hibernate.validator.internal.util.Version" level="WARN"/>
<Logger name="org.apache.coyote.http11.Http11NioProtocol" level="WARN"/>
<Logger name="org.apache.tomcat.util.net.NioSelectorPool" level="WARN"/>
<Logger name="org.apache.catalina.startup.DigesterFactory" level="ERROR"/>
<Logger name="org.springframework" level="INFO" />
<Logger name="com.springboot.mybatis.demo" level="DEBUG"/>
<!--以上的logger会继承Root,也就是说他们默认会输出到Root下定义的符合条件的Appender中,若不想让它继承可以设置 additivity="false"
并可以在Logger中设置 <AppenderRef ref="Console"/> 指定输出到Console-->
<Root level="INFO">
<AppenderRef ref="Console" />
<AppenderRef ref="RollingAllFile"/>
<AppenderRef ref="RollingErrorFile"/>
<AppenderRef ref="RollingWarnFile"/>
</Root>
</Loggers>
</Configuration>
到此我们就算是把日志集成进去了,可以在终端看到各种log,very exciting!!!
4.集成MybatisProvider
• Why ?
有了它我们可以通过注解的方式结合动态SQL实现基本的增删改查操作,而不需要再在xml中写那么多重复繁琐的SQL了
• Come on ↓
First: 定义一个Mapper接口并实现基本操作,如下:
package com.springboot.mybatis.demo.mapper.common; import com.springboot.mybatis.demo.mapper.common.provider.AutoSqlProvider; import com.springboot.mybatis.demo.mapper.common.provider.MethodProvider; import com.springboot.mybatis.demo.model.common.BaseModel; import org.apache.ibatis.annotations.DeleteProvider; import org.apache.ibatis.annotations.InsertProvider; import org.apache.ibatis.annotations.SelectProvider; import org.apache.ibatis.annotations.UpdateProvider; import java.io.Serializable; import java.util.List; public interface BaseMapper<T extends BaseModel, Id extends Serializable> { @InsertProvider(type = AutoSqlProvider.class, method = MethodProvider.SAVE) int save(T entity); @DeleteProvider(type = AutoSqlProvider.class, method = MethodProvider.DELETE_BY_ID) int deleteById(Id id); @UpdateProvider(type = AutoSqlProvider.class, method = MethodProvider.UPDATE_BY_ID) int updateById(Id id); @SelectProvider(type = AutoSqlProvider.class, method = MethodProvider.FIND_ALL) List<T> findAll(T entity); @SelectProvider(type = AutoSqlProvider.class, method = MethodProvider.FIND_BY_ID) T findById(T entity); @SelectProvider(type = AutoSqlProvider.class, method = MethodProvider.FIND_AUTO_BY_PAGE) List<T> findAutoByPage(T entity); }
其中AutoSqlProvider是提供sql的类,MethodProvider是定义好我们使用MybatisProvider需要实现的基本持久层方法,这两个方法具体实现如下:
package com.springboot.mybatis.demo.mapper.common.provider; import com.google.common.base.CaseFormat; import com.springboot.mybatis.demo.mapper.common.provider.model.MybatisTable; import com.springboot.mybatis.demo.mapper.common.provider.utils.ProviderUtils; import org.apache.ibatis.jdbc.SQL; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import java.lang.reflect.Field; import java.util.List; public class AutoSqlProvider { private static Logger logger = LoggerFactory.getLogger(AutoSqlProvider.class); public String findAll(Object obj) { MybatisTable mybatisTable = ProviderUtils.getMybatisTable(obj); List<Field> fields = mybatisTable.getMybatisColumnList(); SQL sql = new SQL(); fields.forEach(field -> sql.SELECT(CaseFormat.UPPER_CAMEL.to(CaseFormat.LOWER_UNDERSCORE, field.getName()))); sql.FROM(mybatisTable.getName()); logger.info(sql.toString()); return sql.toString(); } public String save(Object obj) {
... return null; } public String deleteById(String id) {
... return null; } public String findById(Object obj) {
... return null; } public String updateById(Object obj) {
... return null; } public String findAutoByPage(Object obj) { return null; } }
package com.springboot.mybatis.demo.mapper.common.provider; public class MethodProvider { public static final String SAVE = "save"; public static final String DELETE_BY_ID = "deleteById"; public static final String UPDATE_BY_ID = "updateById"; public static final String FIND_ALL = "findAll"; public static final String FIND_BY_ID = "findById"; public static final String FIND_AUTO_BY_PAGE = "findAutoByPage"; }
注意:
1.如果你在BaseMapper中定义了某个方法一定要在SqlProvider类中去实现该方法,否则将报找不到该方法的错误
2.在动态拼接SQL的时候遇到一个问题:即使开启了驼峰命名转换,在拼接的时候依然需要手动将表属性转换,否则不会自动转换
3.在SqlProvider中的SQL log可以去除,因为在集成日志的时候已经配置好了
4.ProviderUtils是通过反射的方式拿到表的一些基本属性:表名,表属性
• 到这里MybatisProvider的基础配置已经准备好,接下去就是让每一个mapper接口去继承我们这个基础Mapper,这样所有的基础增删改查都由BaseMapper负责,如下:
package com.springboot.mybatis.demo.mapper; import com.springboot.mybatis.demo.mapper.common.BaseMapper; import com.springboot.mybatis.demo.model.User; import java.util.List; public interface UserMapper extends BaseMapper<User,String> { }
这样UserMapper就不需要再关注那些基础的操作了,wonderful !!!
5. 整合JSP过程
• 引入核心包
compile group: 'org.springframework.boot', name: 'spring-boot-starter-web', version: '2.0.0.RELEASE'
// 注意此处一定要是compile或者缺省,不能使用providedRuntime否则jsp无法渲染
compile group: 'org.apache.tomcat.embed', name: 'tomcat-embed-jasper', version: '9.0.6'
providedRuntime group: 'org.springframework.boot', name: 'spring-boot-starter-tomcat', version: '2.0.2.RELEASE' // 此行代码是用于解决内置tomcat和外部tomcat冲突问题,若仅使用内置tomcat则无需此行代码
这是两个基本的包,其中spring-boot-starter-web会引入tomcat也就是我们常说的SpringBoot内置的tomcat,而tomcat-embed-jasper是解析jsp的包,如果这个包没有引入或是有问题则无法渲染jsp页面
• 修改Application启动类
@EnableTransactionManagement @SpringBootApplication public class Application extends SpringBootServletInitializer { @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { setRegisterErrorPageFilter(false); return application.sources(Application.class); } public static void main(String[] args) throws Exception { SpringApplication.run(Application.class, args); } }
注意:启动类必须继承SpringBootServletInitializer 类并重写configure方法
• 创建jsp页面(目录详情如下)
• 接下來就是配置如何去获取jsp页面了,有两中选择
一:通过在application.properties文件中配置
spring.mvc.view.prefix=/WEB-INF/views/
spring.mvc.view.suffix=.jsp
然后创建controller(注意:在Spring 2.0之后如果要返回jsp页面必须使用@Controller而不能使用@RestController)
@Controller // spring 2.0 如果要返回jsp页面必须使用Controller而不能使用RestController public class IndexController { @GetMapping("/") public String index() { return "index"; } }
二:通过配置文件实现,这样的话直接请求 http:localhost:8080/就能直接获取到index.jsp页面,省去了controller代码的书写
@Configuration
@EnableWebMvc
public class WebMvcConfig implements WebMvcConfigurer {
// /static (or /public or /resources or /META-INF/resources
@Bean
public InternalResourceViewResolver viewResolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".jsp");
return resolver;
}
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/").setViewName("index");
}
// 此方法如果不重写的话将无法找到index.jsp资源
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
}
6.集成Shiro认证和授权以及Session
• shiro核心
认证、授权、会话管理、缓存、加密
• 集成认证过程
(1)引包(注:包是按需引用的,以下只是个人构建时候引用的,仅供参考↓)
// shiro
compile group: 'org.apache.shiro', name: 'shiro-core', version: '1.3.2' // 必引包,shiro核心包
compile group: 'org.apache.shiro', name: 'shiro-web', version: '1.3.2' // 与web整合的包
compile group: 'org.apache.shiro', name: 'shiro-spring', version: '1.3.2' // 与spring整合的包
compile group: 'org.apache.shiro', name: 'shiro-ehcache', version: '1.3.2' // shiro缓存
(2)shiro配置文件
@Configuration public class ShiroConfig { @Bean(name = "shiroFilter") public ShiroFilterFactoryBean shiroFilterFactoryBean() { ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean(); //拦截器Map Map<String,String> filterChainDefinitionMap = new LinkedHashMap<String,String>(); //配置不会被拦截的路径 filterChainDefinitionMap.put("/static/**", "anon"); //配置退出 filterChainDefinitionMap.put("/logout", "logout");
//配置需要认证才能访问的路径 filterChainDefinitionMap.put("/**", "authc");
//配置需要认证和admin角色才能访问的路径
filterChainDefinitionMap.put("user/**","authc,roles[admin]") //注意roles中的角色可以为多个且时and的关系,即要拥有所有角色才能访问,如果要or关系可自行写filter
shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap); //配置登陆路径 shiroFilterFactoryBean.setLoginUrl("/login"); //配置登陆成功后跳转的路径 shiroFilterFactoryBean.setSuccessUrl("/index"); //登陆失败跳回登陆界面 shiroFilterFactoryBean.setUnauthorizedUrl("/login"); shiroFilterFactoryBean.setSecurityManager(securityManager()); return shiroFilterFactoryBean; } @Bean public ShiroRealmOne shiroRealmOne() { ShiroRealmOne realm = new ShiroRealmOne(); // 此处是自定义shiro规则 return realm; } @Bean(name = "securityManager") public DefaultWebSecurityManager securityManager() { DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager(); securityManager.setRealm(shiroRealmOne());
securityManager.setCacheManager(ehCacheManager());
securityManager.setSessionManager(sessionManager()); return securityManager; }
@Bean(name = "ehCacheManager") // 将用户信息缓存起来
public EhCacheManager ehCacheManager() {
return new EhCacheManager();
}
@Bean(name = "shiroCachingSessionDAO") // shiroSession
public SessionDAO shiroCachingSessionDAO() {
EnterpriseCacheSessionDAO sessionDao = new EnterpriseCacheSessionDAO();
sessionDao.setSessionIdGenerator(new JavaUuidSessionIdGenerator()); // SessionId生成器
sessionDao.setCacheManager(ehCacheManager()); // 缓存
return sessionDao;
}
@Bean(name = "sessionManager")
public DefaultWebSessionManager sessionManager() {
DefaultWebSessionManager defaultWebSessionManager = new DefaultWebSessionManager();
defaultWebSessionManager.setGlobalSessionTimeout(1000 * 60);
defaultWebSessionManager.setSessionDAO(shiroCachingSessionDAO());
return defaultWebSessionManager;
}
}
自定义realm,继承了AuthorizationInfo实现简单的登陆验证
package com.springboot.mybatis.demo.config.realm; import com.springboot.mybatis.demo.model.Permission; import com.springboot.mybatis.demo.model.Role; import com.springboot.mybatis.demo.model.User; import com.springboot.mybatis.demo.service.PermissionService; import com.springboot.mybatis.demo.service.RoleService; import com.springboot.mybatis.demo.service.UserService; import com.springboot.mybatis.demo.service.impl.PermissionServiceImpl; import com.springboot.mybatis.demo.service.impl.RoleServiceImpl; import com.springboot.mybatis.demo.service.impl.UserServiceImpl; import org.apache.shiro.SecurityUtils; import org.apache.shiro.authc.*; import org.apache.shiro.authz.AuthorizationInfo; import org.apache.shiro.authz.SimpleAuthorizationInfo; import org.apache.shiro.realm.AuthorizingRealm; import org.apache.shiro.session.Session; import org.apache.shiro.subject.PrincipalCollection; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import java.util.ArrayList; import java.util.List; import java.util.stream.Collectors; public class ShiroRealmOne extends AuthorizingRealm { private Logger logger = LoggerFactory.getLogger(this.getClass()); @Autowired private UserService userServiceImpl; @Autowired private RoleService roleServiceImpl; @Autowired private PermissionService permissionServiceImpl; //授权(这里对授权不做讲解,可忽略) @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { logger.info("doGetAuthorizationInfo+" + principalCollection.toString()); User user = userServiceImpl.findByUserName((String) principalCollection.getPrimaryPrincipal()); List<Role> roleList = roleServiceImpl.findByUserId(user.getId()); List<Permission> permissionList = roleList != null && !roleList.isEmpty() ? permissionServiceImpl.findByRoleIds(roleList.stream().map(Role::getId).collect(Collectors.toList())) : new ArrayList<>(); SecurityUtils.getSubject().getSession().setAttribute(String.valueOf(user.getId()), SecurityUtils.getSubject().getPrincipals()); SimpleAuthorizationInfo simpleAuthorizationInfo = new SimpleAuthorizationInfo(); //赋予角色 for (Role role : roleList) { simpleAuthorizationInfo.addRole(role.getRolName()); } //赋予权限 for (Permission permission : permissionList) { simpleAuthorizationInfo.addStringPermission(permission.getPrmName()); } return simpleAuthorizationInfo; } // 认证 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException { logger.info("doGetAuthenticationInfo +" + authenticationToken.toString()); UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken; String userName = token.getUsername(); logger.info(userName + token.getPassword()); User user = userServiceImpl.findByUserName(token.getUsername()); if (user != null) { Session session = SecurityUtils.getSubject().getSession(); session.setAttribute("user", user); return new SimpleAuthenticationInfo(userName, user.getUsrPassword(), getName()); } else { return null; } } }
到此shrio认证简单配置就配置好了,接下来就是验证了
控制器
package com.springboot.mybatis.demo.controller; import com.springboot.mybatis.demo.common.utils.SelfStringUtils; import com.springboot.mybatis.demo.controller.common.BaseController; import com.springboot.mybatis.demo.model.User; import org.apache.shiro.SecurityUtils; import org.apache.shiro.authc.AuthenticationException; import org.apache.shiro.authc.UsernamePasswordToken; import org.apache.shiro.subject.Subject; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.PostMapping; @Controller public class IndexController extends BaseController{ @PostMapping("login") public String login(User user, Model model) { if (user == null || SelfStringUtils.isEmpty(user.getUsrName()) || SelfStringUtils.isEmpty(user.getUsrPassword()) ) { model.addAttribute("warn","请填写完整用户名和密码!"); return "login"; } Subject subject = SecurityUtils.getSubject(); UsernamePasswordToken token = new UsernamePasswordToken(user.getUsrName(), user.getUsrPassword()); token.setRememberMe(true); try { subject.login(token); } catch (AuthenticationException e) { model.addAttribute("error","用户名或密码错误,请重新登陆!"); return "login"; } return "index"; } @GetMapping("login") public String index() { return "login"; } }
