Spring之c3p0连接池配置和使用

1、导入包：c3p0和mchange包

2、代码实现方式：

 package helloworld.pools;

 import com.mchange.v2.c3p0.ComboPooledDataSource;
 import org.springframework.jdbc.core.JdbcTemplate;
 import java.beans.PropertyVetoException;

 /**
  * c3p0连接池使用方法-代码
  * 导入包：c3p0和mchange包
  */
 public class C3p0CodeImpl {
     public static void main(String[] args) {
         ComboPooledDataSource dataSource = new ComboPooledDataSource();
         try {
             dataSource.setDriverClass("com.mysql.jdbc.Driver");
             dataSource.setJdbcUrl("jdbc:mysql://10.15.1.200:3306/gxrdb");
             dataSource.setUser("root");
             dataSource.setPassword("root");
         } catch (PropertyVetoException e) {
             e.printStackTrace();
         }

         // 设置数据源
         JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);

 //        调用jdbcTemplate对象中的方法实现操作
         String sql = "insert into user value(?,?,?)";
         //表结构：id（int、自增）,name(varchar 100),age(int 10)
         int rows = jdbcTemplate.update(sql, null, "Tom2", 25);
         System.out.println("插入行数：" + rows);
     }
 }

3、Spring配置实现方式

beans.xml

 <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:contexnt="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-2.5.xsd">

     <!--配置c3p0连接池-->
     <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
         <!--注入属性-->
         <property name="driverClass" value="com.mysql.jdbc.Driver"></property>
         <property name="jdbcUrl" value="jdbc:mysql://10.15.1.200:3306/gxrdb"></property>
         <property name="user" value="root"></property>
         <property name="password" value="root"></property>
     </bean>

 </beans>
