本文讲述了在Spring Boot应用中，服务层配置时将'ykyServiceImpl'的引用误设为value类型引发的ConversionNotSupportedException问题，重点在于如何通过改正ref属性来修复并避免此类初始化bean失败。

.Error creating bean with name ‘YkyServiceImpl’ defined in class path resource [applicationContext.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 ‘com.mapper.YkyMapper’ for property ‘ykyMapper’; nested exception is java.lang.IllegalStateException: Cannot convert value of type ‘java.lang.String’ to required type ‘com.mapper.YkyMapper’ for property ‘ykyMapper’: no matching editors or conversion strategy found

原因：service层配置时不小心将ref打成了value
