cxf+webservice基本配置及java.lang.ClassCastException: 服务端实体类 cannot be cast to 客户端实体类错误解决**
例如:java.lang.ClassCastException: com.xima.webservice.service.User cannot be cast to com.xima.breast.vo.User
其中User为wenservice传输的bean,两端bean中的属性相同
此处使用springboot,所用pom如下
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!-- http --><dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.1.41</version></dependency><!-- 热部署模块 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-devtools</artifactId><optional>true</optional> <!--这个需要为 true 热部署才有效 --></dependency><!-- CXF webservice --><dependency><groupId>org.apache.cxf</groupId><artifactId>cxf-spring-boot-starter-jaxws</artifactId><version>3.1.11</version></dependency>
先将基本代码附上:
webservice接口:
@WebService(targetNamespace="http://service.webservice.modular.anyu.com")
public interface TestUserService {@WebMethod//标注该方法为webservice暴露的方法,用于向外公布，它修饰的方法是webservice方法，去掉也没影响的，类似一个注释信息。@WebMethodList<User> getUserByAll();
}
webservice接口实现类:
@WebService(serviceName="TestUserService",//对外发布的服务名targetNamespace="http://service.webservice.modular.anyu.com",//指定你想要的名称空间，通常使用使用包名反转endpointInterface="com.anyu.modular.webservice.service.TestUserService")//服务接口全路径, 指定做SEI（Service EndPoint Interface）服务端点接口
@Component
public class TestUserServiceImpl implements TestUserService{@AutowiredBreastCureNodeDao breastCureNodeDao;//dao层,数据库查询public List<User> getUserByAll(){return breastCureNodeDao.selectUserByAll();}}
BreastCureNode 类 (bean):
@XmlRootElement(name="User")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(propOrder= {""})
public class User implements Serializable {private static final long serialVersionUID = 1L;private Integer id;private String userName;private Integer age;private String six;private String school;private Date brithday;//.......get ....set ....toString省略}
webservice配置config
@Configuration
public class CxfConfig {@Autowiredprivate Bus bus;@AutowiredTestUserService testUserService;/*** 此方法作用是改变项目中服务名的前缀名，此处127.0.0.1或者localhost不能访问时，请使用ipconfig查看本机ip来访问* wsdl访问地址为：http://127.0.0.1:8080/soap/user?wsdl* 不用此方法,则访问 : http://127.0.0.1:8080/services/user?wsdl*/
// @SuppressWarnings("all")
// @Bean
// public ServletRegistrationBean dispatcherServlet() {
// return new ServletRegistrationBean(new CXFServlet(), "/soap/*");
// }/*** 方法一*/// @Bean(name = Bus.DEFAULT_BUS_ID)// public SpringBus springBus() {// return new SpringBus();// }//// @Bean// public TestUserService testUserService() {// return new TestUserServiceImpl();// }//// @Bean// public Endpoint endpoint() {// EndpointImpl endpoint = new EndpointImpl(springBus(), testUserService());// endpoint.publish("/user");// return endpoint;// }/** * 方法二* 若有多个webservice,将下面方法复制,修改service和publish即可 **/@Beanpublic Endpoint endpoint() {EndpointImpl endpoint = new EndpointImpl(bus, testUserService);endpoint.publish("/user/breast");endpoint.getInInterceptors().add(new AuthInterceptor());//添加用户密码验证,去掉则客户端不需要用户密码验证return endpoint;}}
AuthInterceptor 用户名密码验证:
public class AuthInterceptor extends AbstractPhaseInterceptor<SoapMessage>{private static final Logger logger = LoggerFactory.getLogger(AuthInterceptor.class);private SAAJInInterceptor saa = new SAAJInInterceptor();private static final String USER_NAME = "admin";private static final String USER_PASSWORD = "admin";public AuthInterceptor() {super(Phase.PRE_PROTOCOL);getAfter().add(SAAJInInterceptor.class.getName());}@Overridepublic void handleMessage(SoapMessage message) throws Fault {SOAPMessage mess = message.getContent(SOAPMessage.class);if (mess == null) {saa.handleMessage(message);mess = message.getContent(SOAPMessage.class);}SOAPHeader head = null;try {head = mess.getSOAPHeader();} catch (Exception e) {logger.error("getSOAPHeader error: {}",e.getMessage(),e);}if (head == null) {throw new Fault(new IllegalArgumentException("找不到Header，无法验证用户信息"));}NodeList users = head.getElementsByTagName("username");NodeList passwords = head.getElementsByTagName("password");if (users.getLength() < 1) {throw new Fault(new IllegalArgumentException("找不到用户信息"));}if (passwords.getLength() < 1) {throw new Fault(new IllegalArgumentException("找不到密码信息"));}String userName = users.item(0).getTextContent().trim();String password = passwords.item(0).getTextContent().trim();//可以从数据库获取用户名密码验证,也可以使用固定的用户名,密码//根据项目需要选择//固定的用户名和密码 此处为admin adminif(USER_NAME.equals(userName) && USER_PASSWORD.equals(password)){logger.debug("admin auth success");} else {SOAPException soapExc = new SOAPException("认证错误");logger.debug("admin auth failed");throw new Fault(soapExc);}}
}
客户端代码:
public class CxfClient {public static void main(String[] args) {CxfClient.main1();CxfClient.main2();}/*** 1.代理类工厂的方式,需要拿到对方的接口地址*/public static void main1() {try {// 接口地址String address = "http://192.168.0.100:8081/services/user/breast?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(TestUserService.class);// 创建一个代理接口实现TestUserService us = (TestUserService) jaxWsProxyFactoryBean.create();// 数据准备// 调用代理接口的方法调用并返回结果String result = us.getUserByAll();System.err.println("返回结果:" + result);} catch (Exception e) {e.printStackTrace();}}/*** 2：动态调用*/public static void main2() {// 创建动态客户端JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();Client client = dcf.createClient("http://192.168.0.100:8081/services/user/breast?wsdl");// 需要密码的情况需要加上用户名和密码client.getOutInterceptors().add(new ClientLoginInterceptor("admin", "admin"));Object[] objects = new Object[0];try {// invoke("方法名",参数1,参数2,参数3....);objects = client.invoke("getUserByAll");List<User> users = (List<User>)objects[0];for (User user : users) {System.out.println(user.toString());}System.err.println("main2 : 动态调用 : 返回数据:" + objects[0]);} catch (java.lang.Exception e) {e.printStackTrace();}}
}
客户端User类:
public class User implements Serializable {private static final long serialVersionUID = 1L;private Integer id;private String userName;private Integer age;private String six;private String school;private Date brithday;//.......get ....set ....toString省略}
ClientLoginInterceptor 验证用户名,密码的类:
public class ClientLoginInterceptor extends AbstractPhaseInterceptor<SoapMessage>
{public ClientLoginInterceptor(String username, String password) {super(Phase.PREPARE_SEND); this.username = username;this.password = password;}private String username; private String password;public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public void handleMessage(SoapMessage soap) throws Fault {List<Header> headers = soap.getHeaders();Document doc = DOMUtils.createDocument();Element auth = doc.createElement("authrity");Element username = doc.createElement("username");Element password = doc.createElement("password");username.setTextContent(this.username);password.setTextContent(this.password);auth.appendChild(username);auth.appendChild(password);headers.add(0, new Header(new QName("tiamaes"),auth));}}
此时基本代码书写完成,启动服务端,输入:http://localhost:8081/services/user/breast?wsdl则可以出现如下页面:
启动客户端: 则会报以下错误:
java.lang.ClassCastException: com.xima.webservice.service.User cannot be cast to com.xima.breast.vo.Userat com.example.demo.CxfClient.main2(CxfClient.java:79)at com.example.demo.CxfClient.main(CxfClient.java:26)
错误原因:
两个bean类的路径不同,导致映射失败;
将客户端User的路径改为com.xima.webservice.service.User即成功在客户端输出User数据
重点说明:bean类所在路径必须是wenservice的路径
