後端-框架-Spring-MyBatis-整合

基礎類(基礎)

public class UserMapperImpl implements UserMapper { 
	private SqlSessionTemplate sqlSession;
    public SqlSessionTemplate getSqlSession() {
    	return sqlSession;
    }
	public void setSqlSession(SqlSessionTemplate sqlSession) {
		this.sqlSession = sqlSession;
 

	}
	
	public List<User> getUserList(User user) {
		return sqlSession.selectList("cn.smbms.dao.user.UserMapper.getUserList", user);
    }
}

基礎類(偷懶)

//SqlSessionDaoSupport支援不用自己建SqlSessionTemplate
public class UserMapperImpl extends SqlSessionDaoSupport implements UserMapper { 
	public List<User> getUserList(User user) {
		return this.getsqlSession().selectList("cn.smbms.dao.user.UserMapper.getUserList", user);
    }
}
