為什么我的網址localhost：8080 ///// ProjectCtxt / mvc / template有效？

Question

以下是我的Spring MVC Web應用程序。

1）我不知道為什么我的應用程序在端口號后帶有四個正斜杠的原因。 如何解決這個問題。

package com.ProjectCtxt.www.controller;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import com.ProjectCtxt.www.service.ProjectService;

@Controller("resultController")
public class ResultController {

    private final ProjectService projectService;

    @Autowired
    public ProjectController(ProjectService projectService) {
        this.projectService = projectService;
    }


    @RequestMapping(value ="/template", method = RequestMethod.GET)
    public String getPersonList(ModelMap model) {

        return   "header";
    }

    @RequestMapping(value ="/search", method = RequestMethod.GET)
    public String getStudentResult(String rNo, ModelMap model){
        return "numberResult";
    }
}

2）同樣，當我在本地計算機上處​​理項目時，我總是使用loclahost：8080 / ProjectCtxt / mvc / template，但是在生產環境中部署時，我希望它是mywebsite.com。 我怎樣才能做到這一點？

2a）當我嘗試www.google.com////calendar/render ，它可以工作。 但是，當我輸入www.google.com/calendar////render它不起作用。

3）如果我使用localhost：8080 / ProjectCtxt / mvc / template，則轉到主頁。 當我單擊jsp中的“搜索”按鈕時，我的URL變為http://localhost:8080/search?regNo 。 但是，如果我手動將localhost:8080/search?regNo=更改為localhost:8080/ProjectCtxt/mvc/search?regNo=可以嗎？ 為什么是這樣？ 如何將網址固定為localhost:8080/ProjectCtxt/mvc/search?regno=而不是手動輸入“ ProjectCtxt / mvc / search？regNo =“

Answer 1

關於/字符：Tomcat只忽略了多余的/字符。 僅上下文路徑之后的部分被路由到您的應用程序。 由每個Web服務器決定如何處理它，因此Google采取不同的方式，這是無法比較的。

關於在您自己的域上托管：通常是在前面的單獨服務器上完成，而不是直接在Tomcat上完成。 例如，使用nginx： Nginx配置可通過上下文將網站直接傳遞到tomcat Webapp

關於表單操作中不正確的URL：由於您使用的是純HTML，因此不會轉換為/ ProjectCtxt / search的實際位置-即使@RequestMapping引用/ search也是這種情況。

使用標准的JSTL Core，“ c：url”標記將自動添加上下文路徑。 另一種選擇是使用Spring Form標簽，該標簽發布到Bean並自動生成正確的路徑。
