java jax-ws webservice
就是服务端程序提供接口,客户端,通过服务端提供的jar包(或者打包的类文件),通过jax-ws直接调用服务端暴露的接口来进行操作.
服务端
共三个文件
接口
package com.jaxwsdemo.serveice;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.Style;
@WebService
@SOAPBinding(style = Style.RPC)
public interface ICalculator {
@WebMethod
float add(@WebParam float a, @WebParam float b);
@WebMethod
float minus(@WebParam float a, @WebParam float b);
@WebMethod
float multiply(@WebParam float a, @WebParam float b);
@WebMethod
float divide(@WebParam float a, @WebParam float b);
}
实现类
package com.jaxwsdemo.serveice.impl;
import com.jaxwsdemo.serveice.ICalculator;
import javax.jws.WebService;
@WebService(endpointInterface = "com.jaxwsdemo.serveice.ICalculator")
public class ICalculatorimpl implements ICalculator {
@Override
public float add(float a, float b) {
System.out.println("a+b="+(a+b));
return a + b;
}
@Override
public float minus(float a, float b) {
System.out.println("a-b="+(a-b));
return a - b;
}
@Override
public float multiply(float a, float b) {
return a * b;
}
@Override
public float divide(float a, float b) {
return a / b;
}
}
发布main类
package com.jaxwsdemo.main;
import com.jaxwsdemo.serveice.impl.ICalculatorimpl;
import javax.xml.ws.Endpoint;
public class mainTest {
public static void main(String[] args) {
System.out.println("发布开始:发布地址:http://localhost:9998/hw");
String address="http://localhost:9998/hw";
Endpoint.publish(address, new ICalculatorimpl());
System.out.println("发布完成");
}
}
运行后会显示发布的地址
此时我们通过访问:http://localhost:9998/hw?wsdl
得到wsdl

此时我们服务端就算是完事了,服务端主要是提供加减乘除接口, 通过Endpoint.publish(address, new ICalculatorimpl());发布别的服务就可以调用了.
在编写服务端之前我们先导出服务端类,共于客户端使用
这里我们使用使用jdk提供的wsimport命令导出
命令:wsimport -s e:/wyc/work http://localhost:9998/hw?wsdl
可以看到导出到了指定位置
小技巧:如果服务端在对方,如何生成服务端的jar包?
通过cmd命令: wsimport -keep http://localhost:9998/hw?wsdl
可直接生成
生成路径就是cmd打开的位置!
我们放到将导出的包放到客户端
客户端编写
完整目录
导出的实现类和接口,与在客户端写的接口结构完全不一样,一定要通过命令导出!!
导出后的接口结构:
package jaxwsdemo.serveice.impl;

public float minus(
@WebParam(name = "arg0", partName = "arg0")
float arg0,
@WebParam(name = "arg1", partName = "arg1")
float arg1);
}
导出后的实现类结构:

注意一定要在客户端加入服务端提供的jar包(此处jar包指的是serveice包)
import jaxwsdemo.serveice.impl.ICalculator;
import java.net.URL;
import java.net.MalformedURLException;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
public class CelintMain {
public static void main(String[] args) throws MalformedURLException {
URL url=new URL("http://localhost:9998/hw?wsdl");
QName qname = new QName("http://impl.serveice.jaxwsdemo.com/", "ICalculatorimplService");
Service service = Service.create(url, qname);
ICalculator cal = service.getPort(new QName("http://impl.serveice.jaxwsdemo.com/", "ICalculatorimplPort"),ICalculator.class);
//cal.add((float)1, (float)2);
float rusult = cal.minus(2, 1);
System.out.println(rusult);
}
}
运行截图
服务端也会有相应的输出因为我们计算时打印了计算过程
服务端此时运行窗口截图
