boot项目找不到注册的mapper

刚刚开始学spring boot,用STS搭建了一个boot项目,
dao层的mapper接口继承了JpaRepository,service层调用findAll(),
controller层调用service的findAll(),
用STS启动时,报如下错误
图片说明
但是用eclipse启动就不报错,
有大佬知道为什么吗?

启动类里面加mapper扫描配置了吗?

启动类里的扫描包的注解是 @MapperScan吗,我这里加不上去

以下是我的工程目录:

启动类:

配置文件application.properties里就配置了数据源

启动类没有基础springboot的加载,改为
public class DemoApplication extends SpringBootServletInitializer{}

@一只小T 加上去之后报错
现在解决了,如下,把boot版本从1.5.7换成1.5.6就运行成功了

但是还是不知道具体原因,有大佬知道吗?

springboot项目中一个mapper里的insert不执行,怎么查看问题的起因?

springboot项目中有一个mapper里的insert标签不执行,语法检查了多次没错,语句在数据库里能运行,但是执行方法时就没反应不执行了,调试时把断点打到了service层数据有传递到,而且把数据直接写到mapper中也写不到数据库中,后来把这句sql的标签由insert换成了delete就执行成功了,有大神知道这是什么错么,或者有没有解决的思路。

springboot项目中使用了mybatisplus的baseMapper中的方法,却提示报错自己的mapper中没有这个方法

报错信息如下: Invalid bound statement (not found): cn.itsource.fastgo.mapper.EmployeeMapper.selectOne 这是service层的接口实现类 @Service @Transactional(readOnly = true,propagation = Propagation.SUPPORTS) public class EmployeeServiceImpl extends ServiceImpl<EmployeeMapper,Employee> implements IEmployeeService { @Override public Employee login(String username, String password) { return baseMapper.selectOne(new QueryWrapper<Employee>() .eq("username",username) .eq("password",password)); } } 这是mapper @Mapper public interface EmployeeMapper extends BaseMapper<Employee> { } 这是controller @RestController public class LoginController { @Autowired private IEmployeeService employeeService; @PostMapping("/login") @ApiOperation(value = "登录接口" + "") public AjaxResult login(@RequestBody Map<String,Object> params){ String username = (String) params.get("username"); String password = (String) params.get("password"); Employee employee = employeeService.login(username,password); if(null!=employee){ //登录成功 return AjaxResult.me(); } //登录失败 return AjaxResult.me().setSuccess(false).setMessage("用户名或密码错误!"); } } 请问大神们为什么调用的是basemapper的selectOne方法,但是会报错employeeMapper找不到selectOne

spring-boot和mybatis配置多数据源,service找不到bean

springboot项目中,加载不了子项目的mapper,除了采用@MapperScan添加,还有别的方法吗?

springboot项目中,引用了多个module,在主项目中启动加载,指挥扫描其所在包下的mapper文件,加载不了子项目的,除了采用@MapperScan添加,还有别的方法吗? 例如: @MapperScan({"com.moyaworks.aaa.service.repository","com.moya.metal.persistence"}) com.moya.metal.persistence这个包是子项目的mapper,不这么写仅仅只会加载repository这个下的mapper文件,现在想问 除了这种方式,还有别的方式吗?

springboot将Controller包、Mapper(DAO)包与启动类放置于同一包内仍扫描不到。

用springboot开发web服务端,同时使用mybatis、swagger。项目目录如下: ![图片说明](https://img-ask.csdn.net/upload/201908/28/1566980273_563041.png) 首先是DAO包中的mapper文件无法扫描到,mybatis-config中已经相关配置: ``` <mappers> <mapper resource="Mapper/*.xml" /> <package name="com.storm.datemanager.DAO"/> </mappers> ``` 运行失败后报如下错误: ``` Description: Field userInfoMapper in com.storm.datemanager.Service.UserInfoService required a bean of type 'com.storm.datemanager.DAO.UserInfoMapper' that could not be found. The injection point has the following annotations: - @org.springframework.beans.factory.annotation.Autowired(required=true) Action: Consider defining a bean of type 'com.storm.datemanager.DAO.UserInfoMapper' in your configuration. ``` 其次,在通过swagger显示controller时为空,url访问controller时报404错误,应该也是没有扫描到Controller文件夹controller代码如下 ``` @CrossOrigin(origins = "*") @RestController @RequestMapping("/admin") @Api(tags = "管理员模块") public class AdminController { @Autowired private UserInfoService userInfoService; @ApiOperation(value = "获取所有用户") @GetMapping("/fetchAllUsers") public Result<List<UserInfo>> fetchAllUsers(@ApiParam("管理员ID")@RequestParam String Id){ return userInfoService.fetchAllUser(Id); } } ``` 后想再次使用componentscan时,仍然报错找不到DAO中的mapper ``` @SpringBootApplication @EnableSwagger2 @ComponentScans(value = { @ComponentScan("com.storm.datemanager.DAO"), @ComponentScan("com.storm.datemanager.Controller") }) public class DatemanagerApplication { public static void main(String[] args) { SpringApplication.run(DatemanagerApplication.class, args); } } ``` 据说springboot的包扫描机制是扫描启动类所在的包以及其子包的所有文件,那么理论上来说这样的目录结构是不需要ComponentScan的,可是为何ComponentScan mapper文件可行,而ComponentScans两个文件夹就不可以? 求大佬解惑

报错信息如下: ``` org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.example.user.dao.UserDao.XXX(方法名) ``` 下面是我application.yml的配置: ``` server: port: 8080 spring: mybatis: mapper-locations: classpath:mapper/*.xml datasource: url: jdbc:mysql://localhost:3306/user?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC&useSSL=true username: root password: root driver-class-name: com.mysql.jdbc.Driver ``` 启动类配置: ``` @SpringBootApplication @MapperScan("com.example.user.dao") public class Demo4Application { public static void main(String[] args) { SpringApplication.run(Demo4Application.class, args); } } ``` 项目结构: ``` UserDao.xml文件在resources的mapper下,UserDao接口在com.example.user.dao下 ``` 有没有大神帮忙看看哪里出的问题。直接在UserDao使用注解是可以访问到的,如下 ``` @Select("SELECT * FROM user_t where id= #{id}") @Results({ @Result(column = "id",property = "id"), @Result(column = "user_name",property = "userName"), @Result(column = "password",property = "password"), @Result(column = "age",property = "age") }) User selectByPrimaryKey(Integer id); ``` 但就是访问不到xml文件中的方法,我使用的Idea2018,有没有大神指导指导,谢谢啦

springboot使用了通用mapper后再自定义mapper产生的bug,求助

1、如果启动类上的@mapperScan(basePackages = "com.imooc.mapper")和application.yml的mybatis配置mapper-locations = "classpath:mapper/*.xml "同时存在的话。则启动时会出现某些bean无法被创建![图片说明](https://img-ask.csdn.net/upload/202005/21/1590027406_520395.png) 2.如果注释掉mapper-locations,则可以正常启动,但是只能扫描到通用mapper无法扫描到自定义mapper![图片说明](https://img-ask.csdn.net/upload/202005/21/1590027484_968513.png) 通用mapper与自定义mapper放在同一个包下,已确定自定义mapper.xml没有任何错误。为什么会出现这种情况?如果让mapper-locations指定扫描一个自定义mapper.xml,则两种bug都不会出现。可是要是有多个自定义mapper该怎么解决?

springboot配置扫描第三方jar的mapper.xml文件

springboot如何配置扫描第三方jar的mapper.xml文件? 使用 ``` ##指向mapper的xml文件位置 mybatis.mapper-locations=classpath:com.weixinmall.mallweb.dao/*Mapper.xml,com.weixinmall.malluser.dao/*Mapper.xml ``` 不生效.在classpath下面根本没有第三方jar的包名.这种情况应该如何配置?

springBoot打包后找不到class,这个class是mybatis插件的!

springboot打包缺少jar包中的class相关错误!

springboot 多模块项目进行service层的单元测试时,mapper接口无法注入进来

如题。service中注入mapper接口都可以正常获取数据。在写service的单元测试时无法注入mapper接口。 service测试类如下: ``` @RunWith(SpringJUnit4ClassRunner.class) @SpringBootTest(classes = TestRunner.class) public class LoginServiceTest { @Autowired private UserMapper userMapper; @Test public void isLogin() throws Exception { User user = new User(); user.setUserName("wangjing"); user.setPassword("1234"); Assert.assertEquals(1,userMapper.isLogin(user)); } } ``` mapper接口如下: ``` @Mapper @Component(value = "userMapper") public interface UserMapper { int isLogin(User user); } ``` 报错信息如下: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.pinganfu.dayu.service.LoginServiceTest': Unsatisfied dependency expressed through field 'userMapper'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.pinganfu.dayu.dal.mapper.UserMapper' available: expected at least 1 bean which qualifies as autowire candidate.

mybatis mapper xml文件路径问题

在spring中使用mybatis.其中目录结构如下 ![图片说明](https://img-ask.csdn.net/upload/201512/13/1449936546_649645.png) spring配置文件如下: ``` <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="configLocation" value="classpath:mybatis.xml"/> </bean> <!-- dao接口的扫描--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="xblog.dal.dao"/> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/> </bean> ``` 其中mybatis配置文件mybatis.xml在resources文件夹中,内容如下: ``` <mappers> <mapper resource="xblog/dal/mybatis/UserMapper.xml" /> <mappers> ``` UserMapper.xml放在java源码的xblog.dal.mybatis这个package下, 测试时,出错: Caused by: java.io.IOException: Could not find resource xblog/dal/mybatis/UserMapper.xml 把UserMapper.xml放在resources目录下,并将mybatis.xml修改为: <mapper resource="UserMapper.xml" /> 就可以通过测试.请问: 如何访问到package目录下的资源.

springboot 多模块打包war,tomcat启动提示找不到配置文件

用反射调用私有方法,mapper没有注入进去的问题

今天跑单元测试遇到一个问题。 用反射调用私有方法,私有方法里面涉及调用数据库 mapper没有注入进去的 报了空指针 类似https://www.jianshu.com/p/4b3f55e76637 这个文章的情况 但是我对他解释的原因不是很认同 因为把private改为public后 就没有报空指针 个人猜测是因为Spring 无法得知私有方法的细节,也就无法注入,请大佬讲一下深入一点的原理 ,或者源码 代码类似于 ``` Class AImpl{ @Autowried private Amapper amapper priavte void f(){ amapper.select(); } } Class Test{ @Autowried private AImpl aImpl; public void test(){ Method method = AImpl.class.getDeclaredMethod("f",null); method.setAccessible(true); method.invoke(aImpl,null); } } ```

150讲轻松搞定Python网络爬虫

【为什么学爬虫?】 &nbsp; &nbsp; &nbsp; &nbsp;1、爬虫入手容易,但是深入较难,如何写出高效率的爬虫,如何写出灵活性高可扩展的爬虫都是一项技术活。另外在爬虫过程中,经常容易遇到被反爬虫,比如字体反爬、IP识别、验证码等,如何层层攻克难点拿到想要的数据,这门课程,你都能学到! &nbsp; &nbsp; &nbsp; &nbsp;2、如果是作为一个其他行业的开发者,比如app开发,web开发,学习爬虫能让你加强对技术的认知,能够开发出更加安全的软件和网站 【课程设计】 一个完整的爬虫程序,无论大小,总体来说可以分成三个步骤,分别是: 网络请求:模拟浏览器的行为从网上抓取数据。 数据解析:将请求下来的数据进行过滤,提取我们想要的数据。 数据存储:将提取到的数据存储到硬盘或者内存中。比如用mysql数据库或者redis等。 那么本课程也是按照这几个步骤循序渐进的进行讲解,带领学生完整的掌握每个步骤的技术。另外,因为爬虫的多样性,在爬取的过程中可能会发生被反爬、效率低下等。因此我们又增加了两个章节用来提高爬虫程序的灵活性,分别是: 爬虫进阶:包括IP代理,多线程爬虫,图形验证码识别、JS加密解密、动态网页爬虫、字体反爬识别等。 Scrapy和分布式爬虫:Scrapy框架、Scrapy-redis组件、分布式爬虫等。 通过爬虫进阶的知识点我们能应付大量的反爬网站,而Scrapy框架作为一个专业的爬虫框架,使用他可以快速提高我们编写爬虫程序的效率和速度。另外如果一台机器不能满足你的需求,我们可以用分布式爬虫让多台机器帮助你快速爬取数据。 &nbsp; 从基础爬虫到商业化应用爬虫,本套课程满足您的所有需求! 【课程服务】 专属付费社群+每周三讨论会+1v1答疑
