Rejected bean name 'propertyConfigurer': no URL paths identified

I am playing with spring (btw I used to know spring when it uses configuration instead of annotation).
我正在玩 spring （顺便说一句，当它使用配置而不是注释时，我曾经知道 spring）。

Somehow the Autowired doesn't work. Logging at tomcat log, there is no error. The only thing looks suspicious is the "Reject" lines:
不知何故自动连线不起作用。在tomcat日志中记录，没有错误。唯一看起来可疑的是“拒绝”行：

Any help would be greatly appreciated. Thanks
任何帮助将不胜感激。谢谢

First problem
第一个问题
private PersonService personService = new PersonServiceImpl();
You are creating the object yourself instead of having Spring inject it for you. Spring can't autowire beans into objects it doesn't manage.
您是自己创建对象，而不是让 Spring 为您注入它。Spring 不能将 bean 自动装配到它不管理的对象中。
@Autowired
private PersonService personService;
Second problem, add this
第二个问题，添加这个
<mvc:annotation-driven />
to your mvc-dispatcher-servlet.xml, otherwise Spring uses the default DispatcherServletconfiguration which might not be what you want.
到您的mvc-dispatcher-servlet.xml，否则 Spring 使用DispatcherServlet可能不是您想要的默认配置。
Also, this
还有，这
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/mvc-dispatcher-servlet.xml</param-value>
</context-param>
serves no purpose at the moment since you don't have a ContextLoaderListener.
目前没有任何用途，因为您没有ContextLoaderListener.
For the reject lines, ignore them. The AbstractDetectingUrlHandlerMappinggoes through all your beans to see if they could be used as request handlers.
对于拒绝行，请忽略它们。将AbstractDetectingUrlHandlerMapping通过所有的豆子去看看他们是否可以作为请求处理。

In my case the other solution dint work since I dint autowire a service method and had the mvc annotation config in my servlet config. It is displayed you have set the logging level to "debug" and its for debugging purpose. To hide these from the logs just disable the DEBUG log for the org.springframeworkclasses.
在我的情况下，另一个解决方案可以工作，因为我不需要自动装配服务方法并且在我的 servlet 配置中有 mvc 注释配置。显示您已将日志记录级别设置为“调试”及其用于调试目的。要将这些从日志中隐藏，只需禁用类的调试日志org.springframework。

My Spring Boot application wasn't working, and I noticed the debug message Rejected bean name 'org.springframework.context.annotation.internalConfigurationAnnotationProcessor': no URL paths identified. Turns out that this wasn't a problem at all.. Spring is looking in registered beans for URL mappings - and it's no surprise it doesn't find mappings in many of beans.
我的 Spring Boot 应用程序不工作，我注意到调试消息Rejected bean name 'org.springframework.context.annotation.internalConfigurationAnnotationProcessor': no URL paths identified。事实证明，这根本不是问题.. Spring 正在注册的 bean 中查找 URL 映射 - 并且它在许多 bean 中找不到映射也就不足为奇了。
So if your Spring web application isn't displaying a webpage, check your controller is annotated, a method has appropriate RequestMapping and class has been component scanned ok.
因此，如果您的 Spring Web 应用程序没有显示网页，请检查您的控制器是否已注释，方法是否具有适当的 RequestMapping 并且类是否已被组件扫描。
