Spring自动创建druid数据源

创建一个xml文件，添加坐标

 <bean id="druidDataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
        <property name="url" value="jdbc:mysql://localhost:3306/one"></property>
        <property name="username" value="root"></property>
        <property name="password" value="admin123"></property>
    </bean>

代码自动创建数据源

  ApplicationContext applicationContext = new ClassPathXmlApplicationContext("ApplicationContext.xml");
        DruidDataSource druidDataSource = (DruidDataSource) applicationContext.getBean("druidDataSource");
        Connection connection = druidDataSource.getConnection();
        System.out.println(connection);
        connection.close();
