[英]Ajax request everytime passing through error (not answering in JSONP in server-side jersey/java restful WS?)
[英]Injection error while trying to get WebServiceContext in RESTful WS with Java Jersey
我正在将Jersey用于Java中的RESTFul Web服务,并且试图在Java方法中获取调用方IP地址,而没有作为参数传递。
我在StackOverflow中尝试了其他类似问题的其他帖子,但都没有用。 到目前为止,我遇到了注入错误,而且我不知道如何解决。
这段代码需要在一个服务器的Tomcat 8容器中运行,而在另一服务器的JBoss中运行。 但是,当我将项目部署到其中的任何一个时,启动容器时都会引发相同的错误:
严重:已使用资源和/或提供程序类检测到以下错误和警告:严重:字段缺少依赖项:javax.xml.ws.WebServiceContext com.adamiworks.restfultutorial.JsonService.webServiceContex t
从eclipse运行到Tomcat 8时也会发生此错误。
谁能指出我错了吗?
我有这个课:
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;
}
}
有了这个pom.xml

感谢很多人,包括
我终于做到了!
