我知道,这个问题已经讨论了很多次了。但是,我无法解决问题... 我正在尝试建立一个新的JAX-RS Web服务,访问静态index.html文件可以很好地工作,但是,当我尝试请求该服务时,我会收到404错误。

服务等级:

package com.baumotte.ticketing.endpoints;

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

@ApplicationPath("/tickets")
public class TicketEP {

    @GET
    //@Produces(MediaType.TEXT_PLAIN)
    public String getTickets() {
        return "hello world";
    }

}

我正在尝试访问localhost:8080 / ticketing / rest / tickets /上的Web服务。根据welcome-file-list属性,在localhost:8080 / ticketing /上访问index.html可以正常工作。您对我在那里想念的东西有想法吗? (顺便说一句,我在Tomcat 9.0中使用Eclipse Photon版本)

1 个答案:

答案 0 :(得分:0)

解决方案:ApplicationPath必须是TicketEP:8类中的Path
