action使用autowired时启动tomcat报异常

No matching bean of type [com.mingyi.mylibrary.service.EmpService] 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)}

Error creating bean with name 'indexAction': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.mingyi.mylibrary.service.EmpService com.mingyi.mylibrary.action.IndexAction.empService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.mingyi.mylibrary.service.EmpService] 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)}

本人的异常解决：

况可能就是你的jar有冲突，本人页纠结这个问题好久，我的action中使用@autowired时，启动tomcat时总报异常，但将action中的注掉，dao跟service都是正常的，后来发现两个jar的冲突。因为一个是老版本的spring-servlet.jar,而另个是3.2版本的spring-webmvc.jar,希望对大家有帮助
