UserDAOImpl.java:

package com.bjsxt.dao.impl;

import com.bjsxt.dao.UserDAO;
import com.bjsxt.model.User; public class UserDAOImpl implements UserDAO {
/* (non-Javadoc)
* @see com.bjsxt.dao.UserDAO#save(com.bjsxt.model.User)
*/ private int daoId;
private String daoStatus; public int getDaoId() {
return daoId;
} public void setDaoId(int daoId) {
this.daoId = daoId;
} public String getDaoStatus() {
return daoStatus;
} public void setDaoStatus(String daoStatus) {
this.daoStatus = daoStatus;
} public void save(User user) {
System.out.println("user saved!");
} @Override
public String toString() {
return this.daoId + ":" + this.daoStatus;
}
}

bean.xml:

<beans xmlns="http://www.springframework.org/schema/beans"

常用方法:

<bean id="myDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">

  <!-- results in a setDriverClassName(String) call -->
<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost:3306/mydb"/>
<property name="username" value="root"/>
<property name="password" value="masterkaoli"/>
