所以我的Java / Spring / CXF / MySQL webservice启动并运行，完成了bean验证，在出错时会抛出自定义异常。这一切都很有效。
但是服务可能抛出的未经证实的错误（错误）呢？就像this page调用＆＃34;未建模的故障＆＃34; ，就像连接到后端数据库失败一样。为此，我故意在我的hibernate.properties文件中输入了一个不正确的密码。
所以我创建了一个自定义CXF拦截器以阻止soapfault：
公共类MyOutSoapFaultInterceptor扩展了AbstractSoapInterceptor { private static Logger logger = Logger.getLogger（MyOutSoapFaultInterceptor.class）;
public MyOutSoapFaultInterceptor()
{
super(Phase.MARSHAL);
}
@Override
public void handleMessage( SoapMessage message) throws Fault
{
logger.debug("entering");
Exception e = message.getContent( Exception.class);
if( e == null) {
logger.debug("e is null");
} else {
logger.debug("e is not null");
logger.debug("e.getCause:" + e.getCause());
logger.debug("e.getMessage:" + e.getMessage());
if( e instanceof Fault) {
logger.debug("e is instanceOf Fault");
SoapFault sf = SoapFault.createFault((Fault) e, message.getVersion());
logger.debug("sf is not null");
logger.debug("sf.getCause:" + sf.getCause());
logger.debug("sf.getMessage:" + sf.getMessage());
logger.debug("sf.getStatusCode:" + sf.getStatusCode());
logger.debug("sf.getCode:" + sf.getCode());
Fault newwFault = new Fault( new Exception("dammit"), Fault.FAULT_CODE_SERVER);
newwFault.setMessage("argh");
throw newwFault;
}
}
}
appclient.xml的相关部分：
<bean id="formsWebServicePortProxy" class="org.springframework.remoting.jaxws.JaxWsPortProxyFactoryBean">
<property name="wsdlDocumentUrl" value="http://localhost:8080/dept_forms_webservice/formsService?wsdl"/>
<property name="serviceInterface" value="mycom.dept.forms.web.endpoint.FormsEndpoint"/>
<property name="serviceName" value="FormsEndpointImplService"/>
<property name="portName" value="FormsEndpointImplPort"/>
<property name="namespaceUri" value="http://endpoint.web.forms.dept.mycom/"/>
</bean>
我测试我的服务的非网络客户端应用程序包含以下代码段：
ApplicationContext ctx = new ClassPathXmlApplicationContext("appclient.xml");
theApp.formsWebServicePortProxy = (FormsEndpoint) ctx.getBean("formsWebServicePortProxy");
logger.debug("entering");
System.out.println("entering testFindAllPermits");
java.util.List<mycom.dept.forms.web.endpoint.Permit> list_permit;
try {
System.out.println("inside try block");
list_permit = formsWebServicePortProxy.findAllPermit(); // <-- error thrown
ListIterator<Permit> iter = list_permit.listIterator();
while( iter.hasNext()) {
System.out.println( iter.next().toString());
}
} catch ( org.springframework.remoting.jaxws.JaxWsSoapFaultException f) {
System.out.println("caught JaxWsSoapFaultException");
f.printStackTrace(); // <-- error thrown here
} catch ( Exception e) {
System.out.println("caught Exception");
System.out.println("e.getCause:" + e.getCause());
System.out.println("e.getMessage:" + e.getMessage());
if( e instanceof FormsEndpointException) {
System.out.println("caught FEE");
}
e.printStackTrace();
}
logger.debug("exiting");
产生以下结果：
inside try block

所有人的根似乎是
Caused by: com.ctc.wstx.exc.WstxEOFException: Unexpected EOF in prolog
at [row，col {unknown-source}]：[1,0 ....
此错误会导致this page之类的一些点击，表明我从网络服务获得空响应。或者更准确地说，是一个空肥皂体。但谷歌搜索引发了很多例子，并且引发了新的错误（新的例外（＆＃34; foo＆＃34;））;＆＃34;也许我没有在客户端正确处理事情？
TIA，
