二.搭建WebService服务端

1.添加相关依赖

在SpringBoot骨架工程的基础上，导入以下Jar包

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web-services</artifactId>
            <version>2.5.2</version>
        </dependency>
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-frontend-jaxws</artifactId>
            <version>3.4.3</version>
        </dependency>
        <dependency>
            <groupId>org.apache.cxf</groupId>
            <artifactId>cxf-rt-transports-http</artifactId>
            <version>3.4.3</version>
        </dependency>

2、创建服务端接口

@WebService(name = "DemoService", // 暴露服务名称
    targetNamespace = "http://service.webserviceprovider.lwq.com") // 命名空间,一般是接口的包名倒序
public interface DemoService {
    public String sayHello(@WebParam(name = "name") String name);
}

3、创建接口实现类

@Component
@WebService(name = "Demoservice", // 与接口中指定的name一致
    targetNamespace = "http://service.webserviceprovider.lwq.com", // 与接口中的命名空间一致,一般是接口的包名倒序
    endpointInterface = "com.lwq.webserviceprovider.service.DemoService") // 接口地址
public class DemoServiceImpl implements DemoService {
    @Override
    public String sayHello(String name) {
        return "你好:" + name;
    }
}

4、创建CXF配置类

@Configuration
public class CxfConfig {
    @Bean
    public ServletRegistrationBean createServletRegistrationBean() {
        return new ServletRegistrationBean(new CXFServlet(), "/demo/*");
    }
    @Bean(name = Bus.DEFAULT_BUS_ID)
    public SpringBus springBus() {
        return new SpringBus();
    }
    @Bean
    public DemoService demoService() {
        return new DemoServiceImpl();
    }
    @Bean
    public Endpoint endpoint() {
        EndpointImpl endpoint = new EndpointImpl(springBus(), demoService());
        endpoint.publish("/api");
        return endpoint;
    }
}

5、启动并测试

启动服务端，并用SoapUI访问 http://localhost:8080/demo/api?wsdl，找到sayHello方法，输入参数，查看结果。
