实现自己的mapper出现的问题 #532
Description
现在是ssm架构的spring 4.3.18 ，mybatis3.4.1 ，mybatis-spring1.3.1 ，通用mapper4.1.5 Intellij IDEA
通用mapper已按照wiki配置好（但是@Autowired红线？ @resource不红）
我模仿https://mapperhelper.github.io/docs/5.professional/还有https://github.com/abel533/Mybatis-Spring写一个继承mapper和insertlistmapper的mymapper，再写通用service.
mymapper已经放在base-package外（有看到说4.0好像不需要还是？？），并在xml里的扫描器配置好mappers=com.xxx.utils.MyMapper了，但是运行报错
使用@resource注解mapper时会报
Error creating bean with name 'adminBaseService': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type 'com.lwq.util.MyMapper<?>' available: expected single matching bean but found 15: adminMapper,attendMapper,classMapper,classStudentMapper,courseMapper,courseStudentMapper,groupMapper,groupStudentMapper,leaveMapper,loginLogMapper,markMapper,messageMapper,recipientMapper,studentMapper,teacherMapper at org.springframework.context.annotation.CommonAnnotationBeanPostProcessor.postProcessPropertyValues
使用@Autowired注解mapper时会报
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'adminController': Unsatisfied dependency expressed through field 'adminBaseService'; nested exception is org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'adminBaseService' is expected to be of type 'com.lwq.service.impl.AdminBaseService' but was actually of type 'com.sun.proxy.$Proxy31'
当我写了16个空mapper时候会报
Error creating bean with name 'courseSMapper' defined in file [D:\Program Files\apache-tomcat-9.0.12\webapps\ROOT\WEB-INF\classes\com\lwq\mapper\CourseSMapper.class]: Invocation of init method failed; nested exception is tk.mybatis.mapper.MapperException: tk.mybatis.mapper.MapperException: java.lang.StringIndexOutOfBoundsException: String index out of range: -1 这时候删掉几个mapper就会报上面的了
所以说现在问题在哪里，求前辈们指点一下
