今天,在运行springboot项目遇到了报错,经过研究后终于发现了坑在哪里,记录以下,避免再次踩坑。
- ***************************
-
- APPLICATION FAILED TO START
-
- ***************************
-
- Description:
-
- Field roleMapper in com.onezero.springboottest.service.impl.RoleServiceImpl required a bean of type 'com.onezero.springboottest.mapper.RoleMapper' 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.onezero.springboottest.mapper.RoleMapper' in your configuration.
虽然说注解都没有遗漏,都添加到指定的地方,但是在运行应用时仍然报错,报错信息如下:
Field roleMapper in com.onezero.springboottest.service.impl.RoleServiceImpl required a bean of type 'com.onezero.springboottest.mapper.RoleMapper' that could not be found.
The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)
翻译过来就是:
com.onezero.springboottest.service.impl.RoleServiceImpl中的变量roleMapper没有找到依赖的一个com.onezero.springboottest.mapper.RoleMapper类型的实体类。
研究之后发现,问题出在引入的依赖上,注意引入的依赖是mybatis-spring-boot-starter,而不是mybatis,所以需要将pom.xml文件中引入的依赖做下修改,引入新的mybatis-spring-boot-starter依赖.
<!--<dependency>-->
<!--<groupId>org.mybatis</groupId>-->
<!--<artifactId>mybatis</artifactId>-->
<!--<version>3.4.1</version>-->
<!--</dependency>-->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>2.0.1</version>
</dependency>
修改之后在试着去重启应用,发现启动成功了!
顺利从坑里出来!
