嘗試使用Java Jersey在RESTful WS中獲取WebServiceContext時出現注入錯誤

[英]Injection error while trying to get WebServiceContext in RESTful WS with Java Jersey

 原文  2016-12-05 23:57:05  3   1    java/ rest/ maven/ dependency-injection

問題描述

我正在將Jersey用於Java中的RESTFul Web服務，並且試圖在Java方法中獲取調用方IP地址，而沒有作為參數傳遞。

我在StackOverflow中嘗試了其他類似問題的其他帖子，但都沒有用。 到目前為止，我遇到了注入錯誤，而且我不知道如何解決。

這段代碼需要在一個服務器的Tomcat 8容器中運行，而在另一服務器的JBoss中運行。 但是，當我將項目部署到其中的任何一個時，啟動容器時都會引發相同的錯誤：

嚴重：已使用資源和/或提供程序類檢測到以下錯誤和警告：嚴重：字段缺少依賴項：javax.xml.ws.WebServiceContext com.adamiworks.restfultutorial.JsonService.webServiceContex t

從eclipse運行到Tomcat 8時也會發生此錯誤。

誰能指出我錯了嗎？

我有這個課： 

package com.adamiworks.restfultutorial;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.xml.ws.WebServiceContext;
import javax.xml.ws.handler.MessageContext;

@Path("/json")
public class JsonService {

    @Context
    WebServiceContext webServiceContext;

    @GET
    @Path("/{param}")
    @Produces(MediaType.APPLICATION_JSON)
    public JsonObject getMsg(@PathParam("param") String msg) {

        HttpServletRequest request = this.getHttpContext();

        String clientIpAddress = request.getHeader("X-FORWARDED-FOR");

        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        Date d = null;
        try {
            d = sdf.parse("1984-01-08");
        } catch (ParseException e) {
            e.printStackTrace();
        }

        Cliente c = new Cliente();
        c.setNome("Anyone");
        c.setDataNascimento(d);

        JsonObject o = new JsonObject(msg, c);
        o.setText("IP=" + clientIpAddress);

        return o;
    }

    private HttpServletRequest getHttpContext() {

        MessageContext mc = webServiceContext.getMessageContext();
        HttpServletRequest request = (HttpServletRequest) mc.get(MessageContext.SERVLET_REQUEST);
        return request;
    }

}

有了這個pom.xml

感謝很多人，包括

HRITUPON

大家在這里

每個人都在這里

我終於做到了！

事實證明：

  1. 上下文注入在Jersey 1.xx中不可用-需要升級到版本2+。
  2. Glassfish現在維護從2.xx開始的澤西版，因此pom.xml和web.xml有很多不同；
  3. WebServiceContext和MessageContext是基於SOAP的，在Java RESTFul Web Service中沒有意義，因為它沒有接收到特定的SOAP標頭。

對於那些同樣遇到錯誤的用戶，請注意以下更改：

pom.xml ：更改為Jersey 2.24.1
