}

不知道哪里出错了。。希望可以有人指点下

你没注入啊，请在userDaoImpl里写这个 @Autowired public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory) { if (!this.externalSqlSession) { this.sqlSession = new SqlSessionTemplate(sqlSessionFactory); } } 还有你这个写法不知道跟哪个师傅学的，你都配置了MapperScannerConfigurer了那么UserDaoImpl就没有必要写了吧，mybatis会在运行时自动创建代理类。还有你的事物控制有问题
