Exception encountered during context initialization - cancelling refresh attempt
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'problemService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.zgf.pipi.mapper.ProblemMapper org.zgf.pipi.service.impl.ProblemService.problemMapper; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.zgf.pipi.mapper.ProblemMapper] 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)}

Problem.java

IProblemService.java

ProblemService.java (implements IProblemService.java )

ProblemMapper.java

Problem.xml

在 problem.xml 中如果有错误的话，就会报 Error creating bean with name 'problemService': Injection of autowired dependencies failed;

之前看到个排除错误的博客，忘记保存了，再找一找
