spring中bean配置8.0版本数据库
（使用属性文件配置）
上代码！
bean文件：
p,context包需要自行导入
或者复制我的全部代码即可
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd"> <!-- 导入context来引入属性文件 --> <context:property-placeholder location="classpath:db.properties"/> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" p:user="${user}" p:password="${password}" p:driverClass="${driverclass}" p:jdbcUrl="${jdbcurl}"> </bean> </beans>
da.properties文件：
跟直接配置稍有不同，可以参考上篇文章,点击下面文字：
user=root password=123456 driverclass=com.mysql.cj.jdbc.Driver jdbcurl=jdbc:mysql://localhost:3306/daname?useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8
测试类文件：
package springDemo.properties; import java.sql.SQLException; import javax.sql.DataSource; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class Main { public static void main(String[] args) throws SQLException { // TODO Auto-generated method stub ApplicationContext ctx = new ClassPathXmlApplicationContext("beans-properties.xml"); DataSource dataSource = (DataSource)ctx.getBean("dataSource"); System.out.println(dataSource.getConnection()); } }
