Daoimpl层里面继承SqlSessionDaoSupport,可以简化代码,直接获取到SqlSession,
SqlSessionDaoSupport里面有setSqlSessionFactory可以进行设值注入。
public class UserMapperImpl extends SqlSessionDaoSupport implements UserMapper { /* private SqlSessionTemplate sqlSession; public void setSqlSession(SqlSessionTemplate sqlSession) { this.sqlSession = sqlSession; }*/ @Override public List<User> getUserList(User user) { //使用SqlSessionTemplate //return sqlSession.selectList("cn.smbms.dao.user.UserMapper.getUserList", user); //使用SqlSessionDaoSupport return this.getSqlSession().selectList("cn.smbms.dao.user.UserMapper.getUserList", user); } /*public SqlSessionTemplate getSqlSession() { return sqlSession; }
更改applicationContext.xml
