使用JAX-WS发布WebService

JAX-WS是Java EE的标准API，用于创建和发布SOAP-based Web服务。以下步骤展示如何通过JAX-WS发布WebService：

定义服务接口
使用@WebService注解标记接口或类：

@WebService
public interface HelloWorld {
    String sayHello(String name);
}

实现服务类
实现接口并添加@WebService注解：

@WebService(endpointInterface = "com.example.HelloWorld")
public class HelloWorldImpl implements HelloWorld {
    public String sayHello(String name) {
        return "Hello, " + name;
    }
}

发布服务
使用Endpoint类发布服务：

public class Publisher {
    public static void main(String[] args) {
        String url = "http://localhost:8080/hello";
        Endpoint.publish(url, new HelloWorldImpl());
        System.out.println("Service published at: " + url);
    }
}

使用Spring Boot发布WebService

Spring Boot整合CXF或Spring Web Services简化发布流程：

添加依赖
在pom.xml中添加Spring Web Services依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web-services</artifactId>
</dependency>

定义服务端点
创建服务类并使用@Endpoint注解：

@Endpoint
public class HelloWorldEndpoint {
    private static final String NAMESPACE = "http://example.com/ws";

    @PayloadRoot(namespace = NAMESPACE, localPart = "sayHelloRequest")
    @ResponsePayload
    public String sayHello(@RequestPayload String name) {
        return "Hello, " + name;
    }
}

配置WSDL生成
创建配置类定义Wsdl11Definition：

java如何发布webservice

@Configuration
@EnableWs
public class WebServiceConfig extends WsConfigurerAdapter {
    @Bean
    public ServletRegistrationBean<MessageDispatcherServlet> messageDispatcherServlet(ApplicationContext context) {
        MessageDispatcherServlet servlet = new MessageDispatcherServlet();
        servlet.setApplicationContext(context);
        servlet.setTransformWsdlLocations(true);
        return new ServletRegistrationBean<>(servlet, "/ws/*");
    }

    @Bean(name = "helloWorld")
    public Wsdl11Definition defaultWsdl11Definition() {
        SimpleWsdl11Definition wsdl11Definition = new SimpleWsdl11Definition();
        wsdl11Definition.setWsdl(new ClassPathResource("wsdl/helloWorld.wsdl"));
        return wsdl11Definition;
    }
}

使用Apache CXF发布WebService

CXF是流行的开源框架，支持JAX-WS和JAX-RS：

添加CXF依赖
在pom.xml中配置：

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-frontend-jaxws</artifactId>
    <version>3.4.0</version>
</dependency>

配置CXF Servlet
在web.xml中注册CXF Servlet：

<servlet>
    <servlet-name>CXFServlet</servlet-name>
    <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>CXFServlet</servlet-name>
    <url-pattern>/services/*</url-pattern>
</servlet-mapping>

发布服务
通过Spring配置发布服务：

@Configuration
public class CxfConfig {
    @Bean
    public Server jaxWsServer(HelloWorld helloWorld) {
        JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();
        factory.setServiceClass(HelloWorld.class);
        factory.setAddress("/helloWorld");
        factory.setServiceBean(helloWorld);
        return factory.create();
    }
}
