首先是JAR包 编写webservice的接口 package org.mpc.activiti.webservice;import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;WebService
public interface MpcService {WebMethodWebResult(name address)//返回值的名称为addressString createMpc(WebParam(name name) String name);//定义了一个名称为name的String类型的参数
}编写webservice的实现类 package org.mpc.activiti.webservice;import javax.jws.WebService;WebService(endpointInterface org.mpc.activiti.webservice.MpcService, serviceName MpcService)
public class MpcServiceImpl implements MpcService {public String createMpc(String name) {System.out.println(创建人 name);Mpc mpc new Mpc();mpc.setAdd(香格里拉);return mpc.getAdd();}
}实体类Mpc package org.mpc.activiti.webservice;public class Mpc {private String name;private String add;public String getName() {return name;}public void setName(String name) {this.name name;}public String getAdd() {return add;}public void setAdd(String add) {this.add add;}
}在主程序中发布web service package org.mpc.activiti.webservice;import javax.xml.ws.Endpoint;public class Main {public static void main(String args[]) throws Exception {//实例化一个MpcServiceImpl的对象并在http://localhost:9090/mpc的地址中发布webserviceEndpoint.publish(http://localhost:9090/mpc, new MpcServiceImpl());System.out.println(服务启动...);Thread.sleep(100 * 60 * 1000);//随意设个时间不要立马退出程序最好长一点System.exit(0);}}运行main以后在浏览器中输入http://localhost:9090/mpc?wsdl会看到如下内容 wsdl:definitions xmlns:ns1http://schemas.xmlsoap.org/soap/http xmlns:soaphttp://schemas.xmlsoap.org/wsdl/soap/ xmlns:tnshttp://webservice.activiti.mpc.org/ xmlns:wsdlhttp://schemas.xmlsoap.org/wsdl/ xmlns:xsdhttp://www.w3.org/2001/XMLSchema nameMpcService targetNamespacehttp://webservice.activiti.mpc.org/

/wsdl:definitions在这份wsdl文档结构中我们可以得到如下信息 有name 和 address 两个string类型的变量有两个消息分别是createMpc和createMpcResponse两者都是用来和activiti交互的消息前者接受参数后者返回信息 还有MpcService中的creatreMpc方法供activiti调用。 在activiti5中访问webservice
方式一 直接的、纯粹的webservice

上面的方式太复杂而且没有图形化的设计界面容易出错下面这种就好多了。
使用的jar包和方式一是一样的。
流程图 然后可以利用图形化的工具来编辑我们的service task 当然也可以用xml的方式编辑这是完成后的xml ?xml version1.0 encodingUTF-8?

绿条没问题
web service的输出有上次的测试输出所以是两条 测试端的输出 下面是service task 的另一种变化 shell service
和以上两个测试在同一个工程下所以JAR包们是没有变化的。
