以上是xml文件

以下为Dao文件

public class UserDao {         	       
     private JdbcTemplate jdbc;	
     public void setJdbc(JdbcTemplate jdbc) {		
     		this.jdbc = jdbc;			
     }	
     public void update(User user){   
        String sql = "update t_user  set userName=?,passWord=? where id=?";	
        Object[] args = {user.getId(),user.getUserName(),user.getPassWord()};	
        jdbc.update(sql, args);	
        }
     }

测试如下:

public class App {	
        public static void main(String[] args) {	
             User user = new User(); 	   
             user.setId(1);	     
             user.setUserName("jr");	     
             user.setPassWord("1234");		
             ApplicationContext ac = new ClassPathXmlApplicationContext("bean.xml");		
             UserDao userDao =  (UserDao) ac.getBean("UserId");		
             userDao.update(user);	
             }
       }

jar包如下:
