背景
有时候，不想运行整个boot项目来测试controller下面的方法，耗费时间比较长，而且繁琐，对本地机器压力大
但是有没有不启动整个boot包来通过mapper调用sql来测试controller里面的方法呢？
答案是有的。
实现
创建test包
创建SpringUtil类
import org.springframework.beans.BeansException; import org.springframework.context.ApplicationContext; import org.springframework.context.ApplicationContextAware; import org.springframework.stereotype.Component; /** * 普通类调用Spring bean对象： * 注意：此类需要放到App.java同包或者子包下才能被扫描，否则失效。 */ @Component public class SpringUtil implements ApplicationContextAware{ private static ApplicationContext applicationContext = null; @Override public void setApplicationContext(ApplicationContext applicationContext) throws BeansException { if(SpringUtil.applicationContext == null){ SpringUtil.applicationContext = applicationContext; } } //获取applicationContext public static ApplicationContext getApplicationContext() { return applicationContext; } //通过name获取 Bean. public static Object getBean(String name){ return getApplicationContext().getBean(name); } //通过class获取Bean. public static <T> T getBean(Class<T> clazz){ return getApplicationContext().getBean(clazz); } //通过name,以及Clazz返回指定的Bean public static <T> T getBean(String name,Class<T> clazz){ return getApplicationContext().getBean(name, clazz); } }
创建TestApp类
package com.example.demo.test2; import com.example.demo.controller.Aqjg_thePeriodController; import com.example.demo.mapper.AppAqjgTaskMapper; import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.ApplicationContext; import java.util.List; import java.util.Map; @SpringBootApplication @MapperScan(basePackages = {"com.example.demo.mapper"}) public class TestApp { public static void main(String[] args) { SpringApplication.run(TestApp.class, args); ApplicationContext context = SpringUtil.getApplicationContext(); Aqjg_thePeriodController aqjg_thePeriodController = new Aqjg_thePeriodController(); AppAqjgTaskMapper appAqjgTaskMapper = context.getBean(AppAqjgTaskMapper.class); //你的dao或service List<Map<String,Object>> list = appAqjgTaskMapper.getTestSmsData(); System.out.println("完成"); } }
