Mapper实现类

public class UserMapperImpl implements UserMapper {
    // 我们的所有操作,都使用sqlSession来执行,在原来
    // 现在都使用SqlSessionTemplate
    private SqlSessionTemplate sqlSession;

    public void setSqlSession(SqlSessionTemplate sqlSession) {
        this.sqlSession = sqlSession;
    }

    public List selectUser() {
        UserMapper mapper = sqlSession.getMapper(UserMapper.class);
        return mapper.selectUser();
    }
}
