Maven+Spring+SpringMVC+Mybatis中的常见错误

1 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userEmailController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.wf.emailservice.backend.service.core.IUserEmailService com.wf.emailservice.backend.web.controller.UserEmailController.userEmailService; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userEmailService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.wf.emailservice.backend.service.core.IVivofsService com.wf.emailservice.backend.service.core.impl.UserEmailService.vivofsService; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'vivofsService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.apache.http.impl.client.CloseableHttpClient com.wf.emailservice.backend.service.core.impl.VivofsService.httpClient; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.apache.http.impl.client.CloseableHttpClient] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

错误形式一: No qualifying bean of type [org.apache.http.impl.client.CloseableHttpClient] 无法找到相应的bean

1  No qualifying bean of type [org.apache.http.impl.client.CloseableHttpClient] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

这里主要原因是缺乏HttpClient的配置文件

2. Non-resolvable parent POM: Failure to find:

可能存在的第一个问题: 就是没有设置maven的版本，setting.xml路径/

可能存在第二个问题就是子pom.xml文件都要设置相应的父pom.xml文件的路径

3. 找不到系统配置文件:xxxx.properties

原因在于:Idea软件右侧的maven的profile没有勾选相应的环境
