webservice之jax-ws实现方式服务端

1.什么是webservice?

webservice是一种远程资源调用技术,它的实现方式主要分为两种,

第一种是jaxws方式,它是面向方法的,它的数据类型是xml是基于soap实现传输;

第二种是jaxrs方式,它是面向资源的,它的数据类型是xml或json是基于http协议实现传输。

2.jaxws简单应用

  服务端:

第一步:创建一个简单的web项目,略 

第二步:添加webService的依赖jar包,配置web.xml

 <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-frontend-jaxws</artifactId>
        <version>3.0.1</version>
    </dependency>
注:版本需与springboot对应 否则启动就会报错
在https://mvnrepository.com/artifact/org.apache.cxf/cxf-spring-boot-starter-jaxws查找到jaxws的各种版本,进入之后可以看到对应的springboot版本

问题详情:
Description:

Parameter 1 of constructor in org.springframework.boot.autoconfigure.web.servlet.error.ErrorMvcAutoConfiguration required a bean of type ‘org.springframework.boot.autoconfigure.web.servlet.DispatcherServletPath’ that could not be found.

The following candidates were found but could not be injected:
- Bean method ‘dispatcherServletRegistration’ in ‘DispatcherServletAutoConfiguration.DispatcherServletRegistrationConfiguration’ not loaded because DispatcherServlet Registration found non dispatcher servlet dispatcherServlet

Action:

Consider revisiting the entries above or defining a bean of type ‘org.springframework.boot.autoconfigure.web.servlet.DispatcherServletPath’ in your configuration.

Process finished with exit code 1
 

启动报错(版本问题)

第三步:编写代码

 1 import com.test.demo.service.IDataReceiverService;
 2 import org.apache.cxf.Bus;
 3 import org.apache.cxf.jaxws.EndpointImpl;
 4 import org.springframework.beans.factory.annotation.Autowired;

21     private Bus bus;
22 
23     @Autowired
24     private IDataReceiverService dataReceiverService;
25 
26 
27     /**

31      */
32     @Bean
33     public Endpoint getReceiveData) {
34         EndpointImpl endpoint = new EndpointImplbus, dataReceiverService);
35         endpoint.publish"/receiveData");
36         return endpoint;
37     }
38 
39 }

 第四步:启动项目,查看wsdl说明书

 这里面的路径注意cxf在web中的配置:

 

参数说明:

@WebService:在接口上申明,表示该接口是一个webService服务;
@WebMethod:在接口方法上声明,表示该方法是一个webService服务方法;

@WebServiceendpointInterface=”cn.linc.cxf.interfaces.ServiceUI”,serviceName=”userService”):在该接口实现类定义;

endpointInterface:表示接口服务终端接口名;
serviceName:服务名称;
wsdl解读:有五个节点:服务视图,服务协议和参数的描述,服务实现,参数描述,参数类型描述。

调用展示:


原理解析:
  可以分为三个角色:服务提供者,服务消费者,服务注册中心uddi
  首先由服务提供者发布服务并且在注册中心uddi进行注册
  然后由服务消费者订阅服务,在注册中心uddi上查询到符合条件的服务
  服务注册中心返回服务条件服务的描述文件给服务订阅者
  订阅者根据描述文件进行服务端的服务调用,并返回数据。
