Activiti webService task演示实例

一、webservice的服务端简单实现

@WebServicepublic interface Calculator {@WebMethod@WebResult(name = "num3")public int plus(@WebParam(name = "num1") int num1,@WebParam(name = "num2") int num2);}@WebService(endpointInterface = "com.first.service.Calculator",serviceName = "calculator")public class CalculatorImpl implements Calculator{@Overridepublic int plus(int num1, int num2) {return num1+num2;}}public static void main(String[] args) {Calculator calculator;Server server;calculator = new CalculatorImpl();        JaxWsServerFactoryBean svrFactory = new JaxWsServerFactoryBean();        svrFactory.setServiceClass(Calculator.class);        svrFactory.setAddress("http://localhost:63081/calculator");        svrFactory.setServiceBean(calculator);        svrFactory.getInInterceptors().add(new LoggingInInterceptor());        svrFactory.getOutInterceptors().add(new LoggingOutInterceptor());        server = svrFactory.create();        server.start();}

java实现一个简单的webservice服务端，并且为调用方法的传入传出参数指定名称，方便activiti中引用

 

二、activiti 流程定义文件
