WebService之JDK中wsimport命令

Posted 2020-08-29 jiapeng

1、编写WebService类，使用@WebService注解

package test;

import javax.jws.WebService;

@WebService
public class HelloServiceImpl{

    public String say(String name) {
        return "Hello "+name;
    }
}

WebService类

2、使用main方法发布WebService

package test;

import javax.xml.ws.Endpoint;

public class Publisher {
    public static void main(String[] args) {
        Endpoint.publish("http://192.168.0.103:8088/hello", new HelloServiceImpl());
    }
}

main方法发布WebService

3、发布成功后，访问发布地址+?wsdl获取网络服务描述语言，其中节点内tns冒号表示targetNameSpace，指向引用节点

<port name="HelloServiceImplPort" binding="tns:HelloServiceImplPortBinding">
<soap:address location="http://192.168.0.103:8088/hello"/>
</port>
</service>
</definitions>

WSDL

4、使用JDK中wsimport生成WebService客户端Java类

　wsimport -s . -p com.hjp.stub http://192.168.0.103:8088/hello?wsdl -Xnocompile

-s后面用点表示在当前目录下，-p后面第一个参数表示生成类的包，第二个参数是WebService服务的wsdl，-Xnocompile表示不需要编译，如果去掉-Xnocompile会有编译的class文件

5、将第四步生成好的Java文件，复制到客户端项目中，编写客户端测试代码

package com.hjp.client;

import com.hjp.stub.HelloServiceImpl;
import com.hjp.stub.HelloServiceImplService;

public class Client {

    public static void main(String[] args){
        //创建服务访问点集合对象
        HelloServiceImplService helloServiceImplService=new HelloServiceImplService();
        //获得服务点绑定的类
        HelloServiceImpl helloService=helloServiceImplService.getHelloServiceImplPort();
        //调用服务端方法
        String returnstr=helloService.say("小明");
        System.out.println(returnstr);
    }

}

客户端代码

 6、扩展WebService内参数

如果想修改WSDL内节点名称，可以设置@WebService(在类上)、@WebMethod(在方法上)、@WebParam(在参数前)内name参数

如果排除其中某方法，使用@WebMethod内exclude=true
