Question

我正在努力解决web.xml上的错误，其中所有页面都以404的形式出现，可能有根路径，但我无法确定它的设置等等。

这是我当前的web.xml



<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

我的监听器控制器就像这样

/*
 * User
*/
@RequestMapping(value={"/user/{id}"}, method=RequestMethod.GET)
public ModelAndView profileDisplay(
        HttpServletRequest request, 
        HttpServletResponse response,
        @RequestParam(value="id", required=false) String id
) throws UnknownHostException, MongoException {
    ServiceSerlvet.appendSesssion(request);
    //get search ALL users
    BasicDBObject searchQuery = new BasicDBObject();
        searchQuery.put("_id", new ObjectId(id));
    List<DBObject> searchResponse = PersonController.searchUsers(searchQuery);      

    //System.out.println("response from search user method: "+searchResponse);

        return new ModelAndView("user", "people", searchResponse);
}

这是当前出现的错误。为什么不映射，我该怎么做呢？

/*
 * User
*/
@RequestMapping(value={"/user/{id}"}, method=RequestMethod.GET)
public ModelAndView profileDisplay(
        HttpServletRequest request, 
        HttpServletResponse response,
        @RequestParam(value="id", required=false) String id
) throws UnknownHostException, MongoException {
    ServiceSerlvet.appendSesssion(request);
    //get search ALL users
    BasicDBObject searchQuery = new BasicDBObject();
        searchQuery.put("_id", new ObjectId(id));
    List<DBObject> searchResponse = PersonController.searchUsers(searchQuery);      

    //System.out.println("response from search user method: "+searchResponse);

        return new ModelAndView("user", "people", searchResponse);
}

Answer 1

我先回答了你的一个问题。我现在可以访问我的一个春季应用程序了。这是一个更好的配置。

注意对web.xml的更改，我道歉但映射到/ *会导致调度程序解析所有请求。在某种意义上，您创建一个循环，您的初始映射将由调度程序转发给控制器，然后控制器将使用视图解析程序来映射您的请求应转发的位置。映射到/ *会导致视图解析器映射由调度程序处理。

更改为/导致所有未映射的URL由调度程序处理，因此您的初始映射由调度程序处理，调度程序将其发送到控制器，并且由viewresolver创建的映射将映射到.jsp，导致它到不被调度员接走。道歉。

谢谢Kbm回复我。我已经改变了我的web.xml，并且已经解决了一般映射问题。我遇到了你提到的问题，css，js，图像文件也通过了。

我试图添加拦截网址，但有些东西仍无法正常工作。 http在web.xml中以红色突出显示。当我在eclipse中将鼠标悬停在它上面时表示

cvc-complex-type.2.4.a：从元素'http'开始发现无效内容。其中一个'{“http：// java.sun.com/xml/ns/javaee":description,"http://java.sun.com/xml/ns/javaee":display-name,"http:// java.sun.com/xml/ns/javaee":icon,"http://java.sun.com/xml/ns/javaee":distributable,"http:// java.sun.com/xml/ns/javaee":context-param,"http://java.sun.com/xml/ns/javaee":filter,"http:// java.sun.com/xml/ns/javaee":filter-mapping,"http://java.sun.com/xml/ns/javaee":listener,"http:// java.sun.com/xml/ns/javaee":servlet,"http://java.sun.com/xml/ns/javaee":servlet-mapping,"http:// java.sun.com/xml/ns/javaee":session-config,"http://java.sun.com/xml/ns/javaee":mime-mapping, “http://java.sun.com/xml/ns/javaee":welcome-file-list,,http://java.sun.com/xml/ns/javaee":error- 页面，“http://java.sun.com/xml/ns/javaee":jsp-config,,http://java.sun.com/xml/ns/javaee":security- 约束，“http://java.sun.com/xml/ns/javaee":login-config,,http://java.sun.com/xml/ns/ javaee“：security-role，”http://java.sun.com/xml/ns/javaee":env-entry,"http://java.sun.com/xml/ns/ javaee“：ejb-ref，”http://java.sun.com/xml/ns/javaee":ejb-local-ref,"http://java.sun.com/xml/ns/ javaee“：service-ref，”http://java.sun.com/xml/ns/javaee":resource-ref,"http://java.sun.com/xml/ns/ javaee“：resource-env-ref，”http://java.sun.com/xml/ns/javaee":message-destination-ref,"http：// java.sun.com/xml/ns/javaee":persistence-context-ref,"http://java.sun.com/xml/ns/ javaee“：persistence-unit-ref，”http://java.sun.com/xml/ns/javaee":post-construct,"http：// java.sun.com/xml/ns/javaee":pre-destroy,"http://java.sun.com/xml/ns/javaee":message- 目的地，“http://java.sun.com/xml/ns/javaee":locale-encoding-mapping-list}”是预期的。
