SpringBoot+webservice

今天看到一个项目要和工厂的ERP进行对接，用到了webservice。虽然使用用springboot较为方便，仍是了解一下：

webservice是什么

网上的解释不少，其实就是跨语言和操做系统的的远程调用技术。好比亚马逊，能够将本身的服务以webservice的服务形式暴露出来，咱们就能够经过web调用这些，不管咱们使用的语言是java仍是c，这也是SOA应用一种表现形式。

WSDL(Web Services Description Language)将不管用何种语言书写的web service描述出来，好比其参数或返回值。WSDL是服务端和客户端都能解读的标准格式。客户端经过URL地址访问到WSDL文件，在调用服务端以前先访问WSDL文件。 读取到WSDL后经过客户端的API类能够生成代理类，调用这些代理类就能够访问webservice服务。代理类将客户端的方法变为soap（Simple Object Access Protocol，能够理解为http+xml）格式经过http发送，同时接受soap格式的返回值并解析。

webservice使用

• 建立工程

  

• 添加依赖

• 测试对象TestBean

public class TestBean {
        private String name;
        private String id;

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public String getId() {
            return id;
        }

        public void setId(String id) {
            this.id = id;
        }
    }
复制代码

• 服务端接口

@WebService(name = "testService",targetNamespace = "http://service.webservicedemo.sxt.com")
    public interface Wbservice {

        @WebMethod
        @WebResult()
        public String helloService(@WebParam(name = "name") String name);
        
        @WebMethod
        public ArrayList<TestBean> getAllBean() } 复制代码

• 服务端接口实现

@WebService(name = "testService",
            targetNamespace = "http://service.webservicedemo.sxt.com",
            endpointInterface="com.sxt.webservicedemo.Service.Wbservice")

    @Component
    public class WebserviceImpl implements Wbservice {
        @Override
        public String helloService(String name) {
            return "hello"+name;
        }

        @Override
        public ArrayList<TestBean> getAllBean() {
            ArrayList<TestBean> list = new ArrayList<>();
            TestBean bean1 = new TestBean("zhangsan", "1");
            TestBean bean2 = new TestBean("lisi", "2");
            list.add(bean1);
            list.add(bean2);
            return list;
        }
    }
复制代码

• 发布配置

@Configuration
public class Webserviceconfig {

    @Bean
    public ServletRegistrationBean dispatcherServlet(){
        return new ServletRegistrationBean(new CXFServlet(),"/service/*");//发布服务名称
    }

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

    @Bean
    public Wbservice beanService() {
        return  new WebserviceImpl();
    }

    @Bean
    public Endpoint endpoint() {
        EndpointImpl endpoint=new EndpointImpl(springBus(), beanService());//绑定要发布的服务
        endpoint.publish("/test"); //显示要发布的名称
        return (Endpoint) endpoint;
    }
复制代码

• 客户端调用

public static void main(String[] args) throws Exception {
        JaxWsDynamicClientFactory dcflient=JaxWsDynamicClientFactory.newInstance();

        Client client=dcflient.createClient("http://localhost:8080/service/test?wsdl");

        Object[] objects=client.invoke("getBean","411001");
        System.out.println("*******"+objects[0].toString());
    }
