Ajax,Jquery请求WebService

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 * */
    @WebService
    public interface HelloWS { 
        @WebMethod
        public String sayHello(String name);
    }

SEI实现

import javax.jws.WebService;
    
    /* * SEI实现 * */
    @WebService
    public 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：

    </head>
