本文实例为大家分享了java实现webservice方式的具体代码,供大家参考,具体内容如下
经过测试 jdk1.6.10以下会出现bug 建议使用10以上版本
1、定义接口
package org.enson.chan; import javax.jws.webservice; import javax.jws.soap.soapbinding; @webservice @soapbinding(style=soapbinding.style.rpc) public interface imyservice { public int add(int a , int b); public int max(int a , int b); }
2、实现接口
package org.enson.chan; import javax.jws.webservice; @webservice(endpointinterface="org.enson.chan.imyservice") public class myserviceimpl implements imyservice { public int add(int a, int b) { system.out.println(a+"+"+b+"="+(a+b)); return a+b; } public int max(int a, int b) { system.out.println("a与b比较大小,取大值"+((a>b)?a:b)); return (a>b)?a:b; } }
3、定义服务
package org.enson.chan; import javax.xml.ws.endpoint; public class myserver { public static void main(string[] args) { string address = "http://localhost:8090/ns"; endpoint.publish(address, new myserviceimpl()); } }
4、测试服务
package org.enson.chan; import java.net.malformedurlexception; import java.net.url; import javax.xml.namespace.qname; import javax.xml.ws.service; public class testclient { public static void main(string[] args) { try { url url = new url("http://localhost:8090/ns?wsdl"); qname sname = new qname("http://chan.enson.org/", "myserviceimplservice"); //创建服务 service service = service.create(url,sname); //实现接口 imyservice ms = service.getport(imyservice.class); system.out.println(ms.add(12,33)); //以上服务有问题,依然依赖于imyservie接口 } catch (malformedurlexception e) { // todo auto-generated catch block e.printstacktrace(); } } }
5、testsoap
