java 发布webservice服务

关键点：

1：类上要注解@WebService

2：方法上注解@WebMethod，方法参数：@WebParam来接

3：发布配置：

@Bean
    public ServletRegistrationBean dispatcherServlet() {
        ServletRegistrationBean sbean = new ServletRegistrationBean(new CXFServlet(), "/demo/WebServices/*");
        return sbean;
    }

    @Bean(name = Bus.DEFAULT_BUS_ID)
    public SpringBus springBus() {
        return new SpringBus();
    }

    @Bean
    public DemoService getService() {
        return new DemoService();
    }

    @Bean
    public Endpoint endpoint() {
        EndpointImpl point = new EndpointImpl(springBus(), getService());
        point.publish("demoWebService");
        return point;
    }

4:启动项目，生成wsdl: http://127.0.0.1:8088/demo/WebServices/demoWebService?wsdl

5:调用：

JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
        Client client = dcf.createClient("http://127.0.0.1:8088/demo/WebServices/demoWebService?wsdl");
        Object[] objects = new Object[0];
        try {
            JSONObject jsonObject = new JSONObject();
            jsonObject.put("test001", "01");
                        // invoke("方法名",参数1,参数2,参数3....);
            objects = client.invoke("process", jsonObject.toString(), "123");
            System.out.println("objects[0]:" + objects[0]);
        } catch (Exception e) {
            e.printStackTrace();
        }

6：原理

webservice是一种通讯技术，wsdl 是一个xml文件，描述接口信息，使用soap来提供服务。
