Server端

server部署到一个端口号为80的tomcat中

 

CXFController.java

package com.lwj.controller;

import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.lwj.util.Privileges;
@WebServlet("/login")
public class CXFController extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        doPost(req, resp);
    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {

        Map<String, List<Integer>> privileges = Privileges.getPrivileges();
// 查询当前坐席所能管理的客户，假设为，在这里固定几个数据

        List<Integer> ids1 = new ArrayList<Integer>();
        ids1.add(1);
        ids1.add(2);
        ids1.add(3);

        List<Integer> ids2 = new ArrayList<Integer>();
        ids2.add(4);
        ids2.add(5);
        ids2.add(6);
        
        privileges.put("fw1950", ids1);
        privileges.put("fw1951", ids2);

    }

}

CXFListener.java

package com.lwj.listener;

import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import javax.servlet.annotation.WebListener;
import javax.xml.ws.Endpoint;

import com.lwj.service.ServerImpl;
import com.lwj.service.IServer;
@WebListener
public class CXFListener implements ServletContextListener{

    @Override
    public void contextDestroyed(ServletContextEvent arg0) {
        
        
    }

    @Override
    public void contextInitialized(ServletContextEvent arg0) {
        System.out.println("web service start");
        IServer implementor= new ServerImpl();
        String address="http://localhost:8088/cxf";
        Endpoint.publish(address, implementor);
        System.out.println("web service started");
    }

}

User.java

package com.lwj.po;

public class User {

    private int id;
    private String account;
    private String name;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getAccount() {
        return account;
    }

    public void setAccount(String account) {
        this.account = account;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "User [id=" + id + ", account=" + account + ", name=" + name
                + "]";
    }

}

IServer.java

package com.lwj.service;

import javax.jws.WebService;

@WebService
public interface IServer {

    String getUserOnline();
}

ServerImpl.java

package com.lwj.service;

import java.util.ArrayList;
import java.util.List;
import java.util.Map;

import javax.jws.WebService;

import com.google.gson.Gson;
import com.lwj.po.User;
import com.lwj.util.Privileges;
@WebService(endpointInterface="com.lwj.service.IServer")
public class ServerImpl implements IServer {

    @Override
    public String getUserOnline() {
        Map<String, List<Integer>> privileges = Privileges.getPrivileges();

        List<Integer> list = privileges.get("fw1950");
        List<User> users = new ArrayList<User>();
        if (list != null && list.contains(new Integer(1))) {
            User u = new User();
            u.setId(1);
            u.setAccount("fw1950");
            u.setName("刘文举");
            users.add(u);
        }

        Gson gson = new Gson();
        return gson.toJson(users);
    }

}

Privileges.java

package com.lwj.util;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class Privileges {

    private static Map<String, List<Integer>> privileges = new HashMap<String, List<Integer>>();

    public static Map<String, List<Integer>> getPrivileges() {
        return privileges;
    }

    public static void setPrivileges(Map<String, List<Integer>> privileges) {
        Privileges.privileges = privileges;
    }

}

Client端

client端部署到一个端口号为8082的tomcat上

 

User.java

package com.lwj.po;

public class User {

    private int id;
    private String account;
    private String name;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getAccount() {
        return account;
    }

    public void setAccount(String account) {
        this.account = account;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "User [id=" + id + ", account=" + account + ", name=" + name
                + "]";
    }

}

ClientService.java

package com.lwj.service;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.cxf.endpoint.Client;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;

@WebServlet("/test")
public class ClientService extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        doPost(req, resp);
    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
        Client client = dcf.createClient("http://localhost:8088/cxf?wsdl");

        resp.setContentType("text/xml;charset=utf-8");
        resp.setHeader("Cache-Control", "no-cache");
        try {
            Object[] os = client.invoke("getUserOnline");
            for (Object o : os) {
                System.out.println(o.toString());
                resp.getWriter().write(o.toString());
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

 

如果调用的方法中存在参数，则只需要在invoke中第二个参数中加上，

如：server中方法，String getUserOnline(Integer id);

则在client中调用时：

client.invoke("getUserOnline",1);

    });
}

一、启动server，发布webservice请求

二、访问：http://localhost/server/login，初始化privileges

三、访问：http://localhost:8082/client/，进到index主页，点击右方的聊天图标（chart3.png），页面中弹出信息

　　

　　测试成功。
