RESTful Web 服务中的@POST

2022-01-21 00:00:00 rest java jersey

我一直在尝试使用 Jersey 来理解 RESTful Web 服务中的 @POST.我已经浏览了 http://www.vogella.com/articles/REST/article.html一样，并且能够获得有关@POST 的一些信息，但感到困惑和笨拙.任何人都可以用一个简单的例子来解释@POST 或者分享相同的链接.

I have been trying to understand @POST in RESTful web service using Jersey. I have gone through http://www.vogella.com/articles/REST/article.html for the same and was able to get some information about @POST, but felt confusing and clumpsy. Can anyone explain @POST with a simple example or share links about the same.

通过上面链接中的 TODO 对象实现 @POST 很好，但我希望通过其他一些简单的示例来学习 @POST，以便我可以继续开发自己的复杂 @POST 示例.

Implementing @POST through TODO objects in above link was fine but i wish to learn @POST through some other simple example so that i can go ahead to develop my own complex @POST examples.

帮助将是明显的，谢谢.

Help will be appreciable, Thanks.

请看下面的例子，它可能对你有帮助

Please find example below, it might help you 

package jersey.rest.test;

import javax.ws.rs.DELETE;
import javax.ws.rs.GET;
import javax.ws.rs.HEAD;
import javax.ws.rs.POST;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.core.Response;

@Path("/hello")
public class SimpleService {
    @GET
    @Path("/{param}")
    public Response getMsg(@PathParam("param") String msg) {
        String output = "Get:Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }

    @POST
    @Path("/{param}")
    public Response postMsg(@PathParam("param") String msg) {
        String output = "POST:Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }

    @POST
    @Path("/post")
    //@Consumes(MediaType.TEXT_XML)
    public Response postStrMsg( String msg) {
        String output = "POST:Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }

    @PUT
    @Path("/{param}")
    public Response putMsg(@PathParam("param") String msg) {
        String output = "PUT: Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }

    @DELETE
    @Path("/{param}")
    public Response deleteMsg(@PathParam("param") String msg) {
        String output = "DELETE:Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }

    @HEAD
    @Path("/{param}")
    public Response headMsg(@PathParam("param") String msg) {
        String output = "HEAD:Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }
}
