java - 未找到 JAX-RS
问题描述
我正在用 wildfly 编写简单的 jax-rs 应用程序。我得到一个 404 Not Found 错误:
有课:
package com.trofimovep;
import javax.enterprise.context.ApplicationScoped;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Application;
import javax.ws.rs.core.Response;
@ApplicationScoped
@Path("/he")
public class Start extends Application {
@GET
@Path("/books")
public Response showBooks() {
String output = "This is a BookShop !";
return Response.status(200).entity(output).build();
}
}

我尝试了几乎变体:创建了另一个从 Application 扩展的类,删除了 @ApplicationScoped,并且我的所有操作都没有给出结果,它是http://localhost:8080/he/books上的 404 NOT FOUND 。我做错了什么?为什么它不能通过路径看到消息?
解决方案
我没有看到你在你的 URL 中使用这个
<context-root>/Bookapp</context-root>
所以也许bookapp/he/books
会起作用
