我有一个控制器

@Controller
@RequestMapping("/v2/**")
public class ReactController {

    @RequestMapping(method = RequestMethod.GET)
    public String reactEntry() {
        return "react-entry";
    }
}

当我登录应用程序并浏览登录页面，然后导航到点击此 URL 的页面时，我会得到内容。但是，如果我直接访问 URL（它会访问登录页面，然后直接转发到此 URL），spring 返回状态代码 200，内容长度为 0，并且我的控制器永远不会被命中。

在调试日志记录中，在正常情况下我看到：

[DEBUG] 17 Aug 2018 10:41:50,805 org.springframework.security.web.FilterChainProxy - /v2/ reached end of additional filter chain; proceeding with original chain
[TRACE] 17 Aug 2018 10:41:50,807 org.springframework.web.servlet.DispatcherServlet - Bound request context to thread: SecurityContextHolderAwareRequestWrapper[ org.springframework.security.web.context.HttpSessionSecurityContextRepository Servlet3SaveToSessionRequestWrapper@38f60506]

[DEBUG] 17 Aug 2018 10:41:50,842 org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping - Returning handler method [public java.lang.String rest.controller.ReactController.reactEntry()]

但是，当通过第二种机制命中时，我得到：

[DEBUG] 17 Aug 2018 10:45:32,702 org.springframework.security.web.FilterChainProxy - /v2/ reached end of additional filter chain; proceeding with original chain
[DEBUG] 17 Aug 2018 10:45:32,779 org.springframework.beans.factory.annotation.InjectionMetadata - Processing injected element of bean 'domain.User': PersistenceElement for transient javax.persistence.EntityManager rest.domain.Personnel.entityManager

请注意表明第二行是不同请求的一部分的时间间隔。

似乎在第二种情况下，即使它是相同的 URL，请求也没有映射到 cems DispatcherServlet。
