接口类：IMyService.java

@WebResult(name="testExceptionResult")public void testException() throws MyException;

实现类：MyServiceImpl.java

@Overridepublic void testException() throws MyException{     throw new MyException("this is my exception");}

异常类：MyException.java

public class MyException extends Exception{    public MyException() {        super();        // TODO Auto-generated constructor stub    }    public MyException(String message, Throwable cause) {        super(message, cause);        // TODO Auto-generated constructor stub    }    public MyException(String message) {        super(message);        // TODO Auto-generated constructor stub    }    public MyException(Throwable cause) {        super(cause);        // TODO Auto-generated constructor stub    }}

生成的wsdl文件：

生成的xsd文件：

使用myeclipse的Web Service Explorer调用该接口方法后返回的SOAP消息


     
          
               
        
         S:Server
                 
        
         this is my exception
                 
                    
                         
          
           this is my exception
                       
                     
                         
          
           this is my exception

测试类：

@Test    public void test1() throws Exception{         String namespace = "http://ws01.yzl.com/";         String wsdlUrl = "http://localhost:8080/ws?wsdl";            //1、创建服务(Service)         URL url = new URL(wsdlUrl);         QName qname = new QName(namespace,"MyServiceImplService");         Service service = Service.create(url, qname);                  //2、创建Dispatch         //public interface Dispatch
     
      extends BindingProviderDispatch 接口提供对动态调用服务端点操作的支持。javax.xml.ws.Service 接口作为创建 Dispatch 实例的工厂。          Dispatch
      
        dispatch = service.createDispatch(new QName(namespace,"MyServiceImplPort"), SOAPMessage.class, Service.Mode.MESSAGE);                  //3、创建SOAPMessage         MessageFactory factory = MessageFactory.newInstance();         SOAPMessage message = factory.createMessage();         SOAPPart part = message.getSOAPPart();         SOAPEnvelope envelope = part.getEnvelope();         SOAPBody body = envelope.getBody();         QName portQname = new QName(namespace,                  "testException","ns");         body.addBodyElement(portQname);                  //4、通过Dispatch传递消息,并返回响应消息         SOAPMessage returnMessage = dispatch.invoke(message);         returnMessage.writeTo(System.out);//打印返回消息         System.out.println();    }

结果：

javax.xml.ws.soap.SOAPFaultException: test exception    at com.sun.xml.internal.ws.fault.SOAP11Fault.getProtocolException(SOAP11Fault.java:178)    at com.sun.xml.internal.ws.fault.SOAPFaultBuilder.createException(SOAPFaultBuilder.java:111)    at com.sun.xml.internal.ws.client.dispatch.DispatchImpl.doInvoke(DispatchImpl.java:176)    at com.sun.xml.internal.ws.client.dispatch.DispatchImpl.invoke(DispatchImpl.java:195)    at com.ws02.TestWsException.test1(TestWsException.java:42)    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)    at java.lang.reflect.Method.invoke(Method.java:597)    at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44)    at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15)    at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41)    at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20)    at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28)    at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:31)    at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:73)    at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:46)    at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:180)    at org.junit.runners.ParentRunner.access$000(ParentRunner.java:41)    at org.junit.runners.ParentRunner$1.evaluate(ParentRunner.java:173)    at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28)    at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:31)    at org.junit.runners.ParentRunner.run(ParentRunner.java:220)    at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:46)    at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38)    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467)    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683)    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390)    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)Caused by: com.ws01.MyException: test exception    at com.ws01.IServiceImp.testException(IServiceImp.java:10)    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)    at java.lang.reflect.Method.invoke(Method.java:597)    at com.sun.xml.internal.ws.api.server.InstanceResolver$1.invoke(InstanceResolver.java:235)    at com.sun.xml.internal.ws.server.InvokerTube$2.invoke(InvokerTube.java:135)    at com.sun.xml.internal.ws.server.sei.EndpointMethodHandler.invoke(EndpointMethodHandler.java:246)    at com.sun.xml.internal.ws.server.sei.SEIInvokerTube.processRequest(SEIInvokerTube.java:82)    at com.sun.xml.internal.ws.api.pipe.Fiber.__doRun(Fiber.java:587)    at com.sun.xml.internal.ws.api.pipe.Fiber._doRun(Fiber.java:546)    at com.sun.xml.internal.ws.api.pipe.Fiber.doRun(Fiber.java:531)    at com.sun.xml.internal.ws.api.pipe.Fiber.runSync(Fiber.java:428)    at com.sun.xml.internal.ws.server.WSEndpointImpl$2.process(WSEndpointImpl.java:232)    at com.sun.xml.internal.ws.transport.http.HttpAdapter$HttpToolkit.handle(HttpAdapter.java:460)    at com.sun.xml.internal.ws.transport.http.HttpAdapter.handle(HttpAdapter.java:233)    at com.sun.xml.internal.ws.transport.http.server.WSHttpHandler.handleExchange(WSHttpHandler.java:95)    at com.sun.xml.internal.ws.transport.http.server.WSHttpHandler.handle(WSHttpHandler.java:80)    at com.sun.net.httpserver.Filter$Chain.doFilter(Filter.java:65)    at sun.net.httpserver.AuthFilter.doFilter(AuthFilter.java:65)    at com.sun.net.httpserver.Filter$Chain.doFilter(Filter.java:68)    at sun.net.httpserver.ServerImpl$Exchange$LinkHandler.handle(ServerImpl.java:555)    at com.sun.net.httpserver.Filter$Chain.doFilter(Filter.java:65)    at sun.net.httpserver.ServerImpl$Exchange.run(ServerImpl.java:527)    at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886)    at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908)    at java.lang.Thread.run(Thread.java:619)

客户端抛出了SOAPFaultException异常，服务端没抛出异常

如果修改服务端的代码

throw new MyException("test exception");修改为：throw new RuntimeException("service runtime Exception");

那么客户端和服务端都将抛出异常，因为服务端并未将runtimeException异常抛给客户端。

抛出的异常客户端可以通过捕获SOAPFaultException来获取服务端的错误
