activiti5第五弹 serviceTask中的webserviceTask 以及 shellTask
web service task是BPMN2.0中的一种任务类型，在activiti5中它并没有专门的标签表示，而是使用了service task 来表示。而且有很多要配置的内容是无法用图形化工具来完成的。要使用web service task，当然要先有web service。所以首先要编写一个web service。
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 {
@WebMethod
@WebResult(name = "address")//返回值的名称为address
String 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webservice
Endpoint.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:ns1="http://schemas.xmlsoap.org/soap/http" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://webservice.activiti.mpc.org/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="MpcService" targetNamespace="http://webservice.activiti.mpc.org/"> <wsdl:types> <xs:schema xmlns:tns="http://webservice.activiti.mpc.org/" xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="unqualified" targetNamespace="http://webservice.activiti.mpc.org/" version="1.0"> <xs:element name="createMpc" type="tns:createMpc"/> <xs:element name="createMpcResponse" type="tns:createMpcResponse"/> <xs:complexType name="createMpc"> <xs:sequence> <xs:element minOccurs="0" name="name" type="xs:string"/> </xs:sequence> </xs:complexType> <xs:complexType name="createMpcResponse"> <xs:sequence> <xs:element minOccurs="0" name="address" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:schema> </wsdl:types> <wsdl:message name="createMpcResponse"> <wsdl:part element="tns:createMpcResponse" name="parameters"></wsdl:part> </wsdl:message> <wsdl:message name="createMpc"> <wsdl:part element="tns:createMpc" name="parameters"></wsdl:part> </wsdl:message> <wsdl:portType name="MpcService"> <wsdl:operation name="createMpc"> <wsdl:input message="tns:createMpc" name="createMpc"></wsdl:input> <wsdl:output message="tns:createMpcResponse" name="createMpcResponse"></wsdl:output> </wsdl:operation> </wsdl:portType> <wsdl:binding name="MpcServiceSoapBinding" type="tns:MpcService"> <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/> <wsdl:operation name="createMpc"> <soap:operation soapAction="" style="document"/> <wsdl:input name="createMpc"> <soap:body use="literal"/> </wsdl:input> <wsdl:output name="createMpcResponse"> <soap:body use="literal"/> </wsdl:output> </wsdl:operation> </wsdl:binding> <wsdl:service name="MpcService"> <wsdl:port binding="tns:MpcServiceSoapBinding" name="MpcServiceImplPort"> <soap:address location="http://localhost:9090/mpc"/> </wsdl:port> </wsdl:service> </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

方式二 使用 java delegate来实现web service任务
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
