jersey webservices 404错误

Question

我知道有很多类似的问题都有很多答案。但是他们都没有帮我解决这个问题。这就是为什么我决定发布一个新的问题。所以我基本上使用带角度前端的球衣。当我执行我的网址http://localhost:8081/hibernate-jersey-angularjs/rest/leave/list时，它显示404错误＆＃34;请求的资源不可用＆＃34;。以下是我的web.xml

和webservice：

package com.abc.rest;


import java.util.Iterator;
import java.util.List;


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

import com.abc.dao.AddLeaveDao;

import com.abc.dao.LeaveDao;

import com.abc.entity.LeaveBalance;
//import com.abc.entity.Love;
import com.abc.entity.LeaveDetails;

@Path("/leave")
public class LeaveWS {

    @GET
    @Path("list")
    @Produces({ "application/json" })
    public List<LeaveBalance> list() {
        List l= new LeaveDao().getAllLeaves();
        return l;
    }

    @POST
    @Path("create")
    @Consumes({ MediaType.APPLICATION_JSON})
    @Produces({ "application/json" })
    public String create(LeaveDetails ld) {

        new AddLeaveDao().addDetails(ld);
        System.out.println("Returned  here");
        return "{}";
    }




}

和项目结构：

请帮我解决这个问题

Answer 1

在您的资源中，您的路径映射应以“/”

作为前缀

@Path("/list")
@Produces({ "application/json" })
public List<LeaveBalance> list() {
    List l= new LeaveDao().getAllLeaves();
    return l;
}

如果您使用maven，请执行此更改后，执行mvn clean install以更新资源
