defined in class path resource [spring-service.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type ‘java.lang.String’ to required type

此异常大概意思是，注入失败，不能把String类型的字符串转换为对应的bean，那就是这个mapper映射，有问题了，改成包扫描后解决了
