Java 弹簧控制器'；在根（/）上下文下本地部署到Tomcat wep应用程序时，在启动时调用的

我有一个非常简单的Spring MVC应用程序，其中我配置了dispatcher servlet以接受/模式下的请求，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
          http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
          version="3.0">

    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

</web-app>

现在我想在Tomcat中部署我的web应用程序，并将web上下文根设置为/，这样当点击localhost:8080时，我的索引页就会弹出。 这确实工作正常，但问题是在启动过程中调用了该方法，spring记录了相同的日志，但没有任何浏览器或其他东西来请求该页面

为了从Eclipse更改web应用程序的上下文路径，我正在使用modules选项卡中的上下文描述符

我尝试的是：

i） 通过添加下面的jboss-web.xml，同样的战争在荒野中进行，并且它工作正常，没有在启动时调用/*路径

<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
    <context-root>/</context-root>
</jboss-web>

通过命令行部署显示了相同的问题？

System.out.println

应该提供一些输出，但您发布的日志不包含这样的输出。你认为为什么会调用这个方法？@serg.nechaev-nope，如果我将它部署为ROOT.war并手动启动tomcat，一切都正常。@AntJavaDev啊，好的。请把代理打印到控制台上好吗？只需使用

（HttpSession session，HttpServletRequest req）

而不是

（HttpSession session）

，并添加行

System.out.println（req.getHeader（“用户代理”）@AntJavaDev哦，这可能就是答案。我记得在集成中，eclipse注意到一个成功的webcontainer启动，并在eclipse中打开了一个新的webbrowser视图。这可能是你的幻影请求。“ant java丢失了一个请求。多么尴尬啊……”
<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
    <context-root>/</context-root>
</jboss-web>

    @RequestMapping("/*")
    public ModelAndView index(HttpSession session,HttpServletRequest req) 
    {
        System.out.println(session.getId());
        System.out.println(req.getHeader("user-agent"));
        return new ModelAndView("index");
    }
