Spring WebService 的两种主流实现方式‌

‌Spring-WSSpring Web Services‌采用 ‌Contract First自顶向下‌ 方式先定义 XSD/WSDL再生成 Java 代码。适用于企业级、高可维护性的 SOAP 服务。‌Spring Boot JAX-WS通常用 Apache CXF‌采用 ‌Contract Last自底向上‌ 方式通过 WebService 注解将 Java 类暴露为 Web Service。开发更快速适合快速原型或内部系统集成。1、‌Spring-WSContract First核心步骤‌‌添加依赖‌MavendependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-web-services/artifactId/dependencydependencygroupIdwsdl4j/groupIdartifactIdwsdl4j/artifactId/dependency‌定义 XSD Schema‌如 src/main/resources/xsd/login.xsdxs:schema targetNamespacehttp://example.com/ws/loginelementFormDefaultqualifiedxmlns:xshttp://www.w3.org/2001/XMLSchemaxs:element nameloginRequestxs:complexTypexs:sequencexs:element nameusername typexs:string/xs:element namepassword typexs:string//xs:sequence/xs:complexType/xs:elementxs:element nameloginResponsexs:complexTypexs:sequencexs:element nameresult typexs:string//xs:sequence/xs:complexType/xs:element/xs:schema‌自动生成 Java 类‌使用 JAXB2 Maven 插件plugingroupIdorg.codehaus.mojo/groupIdartifactIdjaxb2-maven-plugin/artifactIdversion1.6/versionconfigurationschemaDirectory${project.basedir}/src/main/resources/xsd//schemaDirectoryoutputDirectory${project.basedir}/src/main/java//outputDirectory/configurationexecutionsexecutiongoalsgoalxjc/goal/goals/execution/executions/plugin‌创建 Endpoint‌Endpointpublic class LoginEndpoint {private static final String NAMESPACE_URI http://example.com/ws/login;PayloadRoot(namespace NAMESPACE_URI, localPart loginRequest)ResponsePayloadpublic LoginResponse login(RequestPayload LoginRequest request) {// 业务逻辑LoginResponse response new LoginResponse();response.setResult(success);return response;}}‌配置 WebServiceConfig‌ConfigurationEnableWspublic class WebServiceConfig extends WsConfigurerAdapter {Beanpublic ServletRegistrationBean messageDispatcherServlet(ApplicationContext context) {MessageDispatcherServlet servlet new MessageDispatcherServlet();servlet.setApplicationContext(context);servlet.setTransformWsdlLocations(true);return new ServletRegistrationBean(servlet, /ws/*);}Bean(name login)public DefaultWsdl11Definition defaultWsdl11Definition(XsdSchema schema) {DefaultWsdl11Definition wsdl new DefaultWsdl11Definition();wsdl.setPortTypeName(loginPort);wsdl.setLocationUri(/ws);wsdl.setSchema(schema);return wsdl;}Beanpublic XsdSchema schema() {return new SimpleXsdSchema(new ClassPathResource(xsd/login.xsd));}}‌访问 WSDL‌启动应用后访问 http://localhost:8080/ws/login.wsdl 查看服务描述。2、‌Spring Boot CXFContract Last‌添加依赖‌dependencygroupIdorg.apache.cxf/groupIdartifactIdcxf-spring-boot-starter-jaxws/artifactIdversion3.3.1/version/dependency‌定义接口与实现类‌WebServicepublic interface OrderWS {WebMethodOrder getOrderById(int id);}WebService(endpointInterface com.example.OrderWS)public class OrderWSImpl implements OrderWS {Overridepublic Order getOrderById(int id) {return new Order(id, Product, 999.99);}}‌配置发布端点‌Configurationpublic class WebServiceConfig {Autowiredprivate OrderWSImpl orderWSImpl;Beanpublic Endpoint endpoint() {EndpointImpl endpoint new EndpointImpl(new SpringBus(), orderWSImpl);endpoint.publish(/orderws);return endpoint;}}‌访问 WSDL‌http://localhost:8080/orderws?wsdl3、‌注意事项‌‌Spring-WS‌ 更适合需要严格契约控制、长期维护的系统。‌CXF JAX-WS‌ 开发更快但耦合度较高适合内部服务或快速迭代场景。避免使用过时的 Axis1/Axis2除非维护遗留系统 ‌。
