spring中bean配置8.0版本数据库(使用属性文件配置)

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:
spring中bean配置8.0版本数据库,时区解决问题!

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());
		
	}

}
