Spring事物

業務層代碼如下:

package com.crm.service.impl;

import com.crm.service.UserService;
import com.crm.dao.UserDao;
import com.crm.po.User;

import java.util.List;
import java.sql.SQLException;

/**
 * UserService類
 * 創建日期: 2009年04月10日
 * 創建時間:23時34分
 */
public class UserServiceImpl implements UserService<User>
{  //SPring注入j
    private UserDao userDao;

    public void setUserDao(UserDao userDao)
    {
        this.userDao = userDao;
    }

    public UserDao getUserDao()
    {
        return userDao;
    }

       //拋出異常
    public void delete(Integer id)throws SQLException
    {

            userDao.delete(id);
            throw new SQLException("有錯誤!");
    }

}

其中userDao是由Spring注入進來的,DAO用的是IBatis，其代碼如下:

import com.crm.dao.UserDao;
import com.crm.po.User;

import java.util.List;
import java.sql.SQLException;

import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;
public class UserDaoImpl extends SqlMapClientDaoSupport implements UserDao<User>
{
     public void update(User user)throws SQLException
    {
        getSqlMapClientTemplate().update("updateUser",user);
    }
}
