Question

我有以下代码（由其他人编码）和各种Rest注释：

package org.koushik.javabrains.messenger.resource;

import java.util.List;
// removed most of import.javax..... imports, to avoid error: it looks like mostly code


import org.koushik.javabrains.messenger.model.Message;
import org.koushik.javabrains.messenger.service.MessageService;

@Path("/messages")
public class MessageResource {
    MessageService messageService = new MessageService();

@GET
@Produces(MediaType.APPLICATION_JSON)
public List<Message> getMessages() {
    return messageService.getAllMessages();
    }
}

我正在使用邮递员休息客户端，在404上使用所有这三种方法时，我收到http://localhost:8080/messenger/webapi/messages响应。

的web.xml：

Rest get和post方法返回404错误
