idea中的ssm项目，修改了包名后，项目就启动不起来了？

Question

org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [mvc-dispatcher.xml]; nested exception is org.springframework.context.annotation.ConflictingBeanDefinitionException: Annotation-specified bean name 'fileController' for bean class [com.sw.controller.FileController] conflicts with existing, non-compatible bean definition of same name and class [com.cm.controller.FileController]
    at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:414)

报名从com.cm改成了com.sw
，所以并不存在`
com.cm.controller.FileController

Answer 1

全局搜索一下之前的包名，漏改了吧

Answer 2

1、 bean 重复，删掉一个就好了。

com.sw.controller.FileController
com.cm.controller.FileController

2、或者加个别名

@RestController("xxxController")
@RequestMapping("common")
public class CommonController {
