Ajax,Jquery请求WebService

来源：互联网发布：视频剪辑软件哪个好编辑：程序博客网时间：2024/05/21 06:39

首先启动一个WebService服务，代码如下：

SEI接口：

import javax.jws.WebMethod;import javax.jws.WebService;/* * SEI接口 * */@WebServicepublic interface HelloWS {    @WebMethod    public String sayHello(String name);}

SEI实现

import javax.jws.WebService;/* * SEI实现 * */@WebServicepublic class HelloWSImpl implements HelloWS {    @Override    public String sayHello(String name) {        System.out.println("server sayHello()"+name);        return "Hello"+name;    }}

WebService实现：

package com.lin.ws.server;import java.util.List;import javax.xml.ws.Endpoint;import org.apache.cxf.interceptor.Interceptor;import org.apache.cxf.interceptor.LoggingInInterceptor;import org.apache.cxf.interceptor.LoggingOutInterceptor;import org.apache.cxf.jaxws22.EndpointImpl;import org.apache.cxf.message.Message;import com.lin.ws.HelloWSImpl;/* * 实现Web Service * */public class ServerTest4 {    public static void main(String[] args) {        String address="http://172.19.183.17:8888/WS/hellows";        Endpoint endpoint= Endpoint.publish(address, new HelloWSImpl());        System.out.println(endpoint);        EndpointImpl endpointImpl=(EndpointImpl) endpoint;        //服务器端的日志入拦截器        List<Interceptor<? extends Message>> inInterceptors= endpointImpl.getInInterceptors();        inInterceptors.add(new LoggingInInterceptor());        //服务器端的日志出拦截器        List<Interceptor<? extends Message>> outInterceptors= endpointImpl.getOutInterceptors();        outInterceptors.add(new LoggingOutInterceptor());        System.out.println("发布Web Service成功！");    }}

启动后，创建一个html文件，准备通过ajax请求WebService服务，直接上代码，代码中有说明：
