Spring jdbcTemplete datasource

1,applicationContext.xml配置bean

 <!-- 配置datasource -->
<bean id="dataSource" 
     class="org.apache.commons.dbcp.BasicDataSource">
    <property name="driverClassName" value="org.gjt.mm.mysql.Driver"/>
    <property name="url" value="jdbc:mysql://localhost:3306/test"/>
    <property name="username" value=""/>
    <property name="password" value=""/>
</bean>


<!-- Jt bean -->
<bean id="jt" class="org.springframework.jdbc.core.JdbcTemplate">
<property name="dataSource" ref="dataSource"></property>
</bean>

<bean id="useDao" class="com.dao.UserDaoImpl">
<property name="jdbcTemplete" ref="jt"></property>
</bean>

2,UserDaoImpl.java

package com.dao;
import org.springframework.jdbc.core.JdbcTemplate;
public class UserDaoImpl extends UserDao{
private JdbcTemplate jdbcTemplete;
public void setJdbcTemplete(JdbcTemplate jdbcTemplete) {
this.jdbcTemplete = jdbcTemplete;
}
public void addData(){
String sql = "insert into m_s(id,name)values(\"6\",\"@-H\")";
jdbcTemplete.update(sql);
}
public int delete(int id){
        String sql = "delete from m_s where id =?";
        return jdbcTemplete.update(sql, new Object[]{id});
}
}

获取bean工具类;GetBeanUtil.java

package util;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class GetBeanUtil {

public static ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");

public static Object getBean(String name){
return ac.getBean(name);
}

}

测试

UserDaoImpl userdao =  (UserDaoImpl) ac.getBean("useDao");
userdao.addData();
userdao.delete(6);

搞定。。。
