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?

你应该吧你的配置弄上来让大家来看!

启动类里的扫描包的注解是 @MapperScan吗,我这里加不上去
图片说明
以下是我的工程目录:

pom:

启动类:
图片说明
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
图片说明
但是还是不知道具体原因,有大佬知道吗?

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

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

SpringBoot中Mapper如果在BaseService里面注入会有什么问题吗?

我们的Service层都会集成一个BaseService. 今天有几个相同的Service用到了同一个Mapper, 我一直以来都是在每个Service中注入一个私有的Mapper. 但是其实在BaseService里面注入一个public的Mapper给Service继承不也能直接用吗? 这样会有什么风险吗?

Sping Boot注入接口失败

![图片说明](https://img-ask.csdn.net/upload/201804/21/1524291637_361310.png) 项目结构应该是正确的。 ``` @Repository public interface UserDao { public User getById(int id); } ``` Dao层的代码,使用接口。 @Service ``` @Service public class UserService { @Autowired UserDao userDao; public User getById(int id) { return userDao.getById(id); } } ``` service层代码。 controller层注入service。 启动spring boot后会提示dao层没有扫描到,如果@ComponentScan dao层的话,会提示service层注入失败,求解。

无代码时代来临,程序员如何保住饭碗?

编程语言层出不穷,从最初的机器语言到如今2500种以上的高级语言,程序员们大呼“学到头秃”。程序员一边面临编程语言不断推陈出新,一边面临由于许多代码已存在,程序员编写新应用程序时存在重复“搬砖”的现象。 无代码/低代码编程应运而生。无代码/低代码是一种创建应用的方法,它可以让开发者使用最少的编码知识来快速开发应用程序。开发者通过图形界面中,可视化建模来组装和配置应用程序。这样一来,开发者直...

《经典算法案例》01-08:如何使用质数设计扫雷(Minesweeper)游戏

我们都玩过Windows操作系统中的经典游戏扫雷(Minesweeper),如果把质数当作一颗雷,那么,表格中红色的数字哪些是雷(质数)?您能找出多少个呢?文中用列表的方式罗列了10000以内的自然数、质数(素数),6的倍数等,方便大家观察质数的分布规律及特性,以便对算法求解有指导意义。另外,判断质数是初学算法,理解算法重要性的一个非常好的案例。
