Question

我有一个Java应用程序，它使用maven，jersey，spring和其他库。

我使用本教程github.com/erkobridee/restful-bookmarks-jerseyspring/tree/master/src/main

作为我项目的指南。

我无法从我的项目结构中发布图片。我的index.html位于src/main/webapp/index.html

当我在浏览器中调用网址http://localhost/decon-fm-5/index.html时，比调用404状态错误。

为什么呢？问题是什么？

我可以使用网址http://localhost/deconFM_V5/app/login

在我的浏览器中调用我的ApplicationController操作

package de.decon.v5.core.controller;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("/app")
public class ApplicationController 
{
    @GET
    @Path("/login")
    @Produces(MediaType.APPLICATION_JSON)
    public String application()
    {
        String loginForm = "{\"form\" : {\"name\" : \"login\"}}";

        return loginForm;
    }
}

非常感谢你的帮助

您正在将所有请求映射到jersy spring servlet，它将在您的Rest Endpoint中查找index.html的映射，如果没有找到它将给出404.理想情况下，您应该映射/api/**或其他东西以供您休息终点。

例如：

http://localhost/decon-fm-5/api/v1/resourcename/id

进行以下更改

 <servlet-mapping>
        <servlet-name>decon-fm-5</servlet-name>
        <url-pattern>/api</url-pattern>
 </servlet-mapping>

在网络休息服务项目中使用maven spring和jersey？
