我们经常需要在两个系统之间进行一些数据的交互,这时候我们就需要开发数据交互接口。
一般来说,遇到比较多的接口有HTTP接口、WebService接口、FTP文件传输。今天我要来学习一下在SpringBoot框架下进行简单的webservice接口的开发。
创建了两个wbservice接口TestService和CatService。
导入相关的依赖包。

public interface TestService {

public String sendMessage(@WebParam(name = "username") String username);

public interface CatService {
@WebMethod
public String message(@WebParam(name = "name") String name);
}
import com.admin.Bag.webservice.server.TestService;
import org.springframework.stereotype.Component;
import javax.jws.WebService;
@WebService(serviceName = "TestService", // 与接口中指定的name一致
targetNamespace = "http://server.webservice.Bag.admin.com", // 与接口中的命名空间一致,一般是接口的包名倒
endpointInterface = "com.admin.Bag.webservice.server.TestService"// 接口地址
)
@Component
public class TestServiceImpl implements TestService {
@Override
public String sendMessage(String username) {
return "=====Hello! " + username + "=====";
}
@Override
public boolean getFlag(String username) {
//
return true;
}
}
import com.admin.Bag.webservice.server.CatService;
import org.springframework.stereotype.Component;
import javax.jws.WebService;
@WebService(serviceName = "CatService", // 与接口中指定的name一致
targetNamespace = "http://server.webservice.Bag.admin.com", // 与接口中的命名空间一致,一般是接口的包名倒
endpointInterface = "com.admin.Bag.webservice.server.CatService"// 接口地址
)
@Component
public class CatServiceImpl implements CatService {
@Override
public String message(String name) {
//
return "一只小猫猫";
}
}
import com.admin.Bag.webservice.server.impl.CatServiceImpl;
import com.admin.Bag.webservice.server.impl.TestServiceImpl;
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 cxfConfig {
@Bean
public ServletRegistrationBean disServlet() {
ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean(new CXFServlet(), "/webService/*");
return servletRegistrationBean;
}
@Bean(name = Bus.DEFAULT_BUS_ID)
public SpringBus springBus() {
return new SpringBus();
}
@Bean
public Endpoint endpoint() {
EndpointImpl endpoint = new EndpointImpl(springBus(), new TestServiceImpl());
endpoint.publish("/TestService");
return endpoint;
}
@Bean
public Endpoint endpoint2() {
EndpointImpl endpoint = new EndpointImpl(springBus(), new CatServiceImpl());
endpoint.publish("/CatService");
return endpoint;
}
}
启动项目。我的项目端口号是8080。浏览器访问地址:http://localhost:8082/webService
可见接口信息CatService和TestService,点进链接可以看每个接口的wsdl文档。
客户端是一个单独的项目。
不同的SpringBoot版本对应的依赖版本也不一样,我也是试了好久终于成了。我的SpringBoot版本号是2.3.0.RELEASE。
<!-- 进行jaxes 服务开发 -->

import org.apache.cxf.endpoint.Client;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
public class clientUtil {
public static String callWebSV(String wsdUrl, String operationName, String... params) throws Exception {
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
Client client = dcf.createClient(wsdUrl);
//client.getOutInterceptors().add(new ClientLoginInterceptor(USER_NAME, PASS_WORD));
Object[] objects;
// invoke("方法名",参数1,参数2,参数3....);
objects = client.invoke(operationName, params);
return objects[0].toString();
}
}
使用定时调用webservice接口。
import com.admin.webAppoint.webservice.client.clientUtil;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.RestController;
@RestController
@Component
public class TestController {
//在一个方法中连续调用多次WebService接口,每次调用前需要重置上下文。
ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
@Scheduled(cron="*/15 * * * * ?")
public String getMessage() {
Thread.currentThread().setContextClassLoader(classLoader);//在获取连接之前 还原上下文
System.out.println("======开始调用webservice接口=====");
String url = "http://localhost:8082/webService/CatService?wsdl";
String methodName = "message";
System.out.println("Calling" + url);
String result="";
try {
result=clientUtil.callWebSV(url, methodName, "name");
} catch (Exception e) {
System.err.println("接口调用失败!!!!");
return "失败";
}
System.out.println("===Finished!===恭喜你啊!!!CatService接口调用成功!!!===获得的数据是:"+result);
return "Finished!";
}
@Scheduled(cron="*/5 * * * * ?")
public String getMessage2() {
Thread.currentThread().setContextClassLoader(classLoader);//在获取连接之前 还原上下文
System.out.println("======开始调用webservice接口=====");
String url = "http://localhost:8082/webService/TestService?wsdl";
String methodName = "sendMessage";
System.out.println("Calling" + url);
String result="";
try {
result=clientUtil.callWebSV(url, methodName, "username");
} catch (Exception e) {
System.err.println("接口调用失败!!!!");
return "失败";
}
System.out.println("===Finished!===恭喜你啊!!!TestService接口调用成功!!!===获得的数据是:"+result);
return "Finished!";
}
}
首先启动服务端。启动客户端。
遇到过报错:
报错——使用cxf时报错:org.apache.cxf.interceptor.Fault: Marshalling Error: XXX is not known to this context
最终成功调用服务端的webservice接口:
