springboot webservice

这里使用的springboot版本是2.0.0，cxf的版本是3.1.12。之前在做这个demo时，因为springboot版本的问题，掉在坑里许久出不来。最开始使用springboot2.1.15版本，一直在报错，所以先声明版本。

这个demo比较简单一个服务端生成webservice服务，一个客户端调用webservice服务

服务端pom.xml

</project>

客户端的pom.xml文件同上

1、声明一个服务接口

package com.example.demo.webservice;

import javax.jws.WebService;
//name是要发布出去的服务名，targetNamespace是服务的命名空间，惯例使用包名反序
@WebService(name = "MyWebService",targetNamespace="http://webservice.demo.com")
public interface MyWebService {
    //接口提供的方法
    String getName(String name);
}

2、写一个实现类，实现1中的接口

package com.example.demo.webservice.impl;

import com.example.demo.webservice.MyWebService;
import javax.jws.WebService;
/**
 *此处的name、targetNamespace 和接口中的相同，endpointInterface 为1中的接口全路径
 *就是要对外提供服务的接口
 */
@WebService(serviceName = "MyWebService",targetNamespace = "http://webservice.demo.com",
            endpointInterface = "com.example.demo.webservice.MyWebService")
public class MyWebServiceImpl implements MyWebService {
    @Override
    public String getName(String name) {
        return "WebService测试成功：" + name;
    }
}

3、服务端配置类

package com.example.demo.webservice;

import com.example.demo.webservice.impl.MyWebServiceImpl;
import org.apache.cxf.Bus;
import org.apache.cxf.bus.spring.SpringBus;
import org.apache.cxf.jaxws.EndpointImpl;
import org.apache.cxf.transport.servlet.CXFServlet;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.xml.ws.Endpoint;

@Configuration
public class WebServiceCfg {
    @Bean
    public ServletRegistrationBean dispatcherServlet(){
        return new ServletRegistrationBean(new CXFServlet(),"/demo/*");
    }

    @Bean(name = Bus.DEFAULT_BUS_ID)
    public SpringBus springBus(){
        return new SpringBus();
    }
    @Bean
    public MyWebService myWebService(){
        return new MyWebServiceImpl();
    }
    @Bean
    public Endpoint endpoint(){
        EndpointImpl endpoint = new EndpointImpl(springBus(), myWebService());
        endpoint.publish("/zb");
        return endpoint;
    }
}

4、启动springboot项目，访问地址 http://localhost:8080/demo/zb?wsdl,会出现以下画面，表示服务发布成功

 5、实现一个测试的客户端

package com.example.client.webservice;

import com.example.demo.webservice.MyWebService;
import org.apache.cxf.endpoint.Client;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;

public class WebServiceTest {

    public static void main(String[] args) {
        //WebServiceTest.test1();
        WebServiceTest.test2();
    }
    /**
     * 1.代理类工厂的方式,需要拿到对方的接口地址
     */
    public static void test1() {
        try {
            // 接口地址
            String address = "http://127.0.0.1:8080/demo/zb?wsdl";
            // 代理工厂
            JaxWsProxyFactoryBean jaxWsProxyFactoryBean = new JaxWsProxyFactoryBean();
            // 设置代理地址
            jaxWsProxyFactoryBean.setAddress(address);
            // 设置接口类型
            jaxWsProxyFactoryBean.setServiceClass(MyWebService.class);
            // 创建一个代理接口实现
            MyWebService us = (MyWebService) jaxWsProxyFactoryBean.create();
            String name = us.getName("张半仙");
            System.out.println(name);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    /**
     * 2：动态调用
     */
    public static void test2() {
        // 创建动态客户端
        JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
        Client client = dcf.createClient("http://127.0.0.1:8080/demo/zb?wsdl");
        // 需要密码的情况需要加上用户名和密码
        // client.getOutInterceptors().add(new MyInterceptor(USER_NAME, PASS_WORD));
        Object[] objects = new Object[0];
        try {
            // invoke("方法名",参数1,参数2,参数3....);
            objects = client.invoke("getName", "张半仙");
            System.out.println("返回数据:" + objects[0]);
        } catch (java.lang.Exception e) {
            e.printStackTrace();
        }
    }
}

6、执行5中代码会打印以下的值，即调用成功

 至此，一个简单的webservice服务端和客户端的demo完成
