java - 如何重写cxf MessageSenderEndingInterceptor并控制handleMessage方法

我使用 jaxws:client 标签和 spring 来使用 Web 服务。在上面的过程中,我想在调用Web服务之前和之后使用cxf拦截器。

iam 能够与 cxf 拦截器一起使用,web 服务返回正确的肥皂错误和成功响应,但 inFaultInterceptor 在以下情况下不会被调用HTTP 状态代码:404而且当服务关闭时...连接异常..

分析错误后..我发现异常是从 https://cxf.apache.org/javadoc/latest/org/apache/cxf/interceptor/MessageSenderInterceptor.MessageSenderEndingInterceptor.html

public class MessageSenderInterceptor extends AbstractPhaseInterceptor<Message> {
private static final ResourceBundle BUNDLE = BundleUtils.getBundle(MessageSenderInterceptor.class);
private MessageSenderEndingInterceptor ending = new MessageSenderEndingInterceptor();


public MessageSenderInterceptor() {
super(Phase.PREPARE_SEND);
}

public void handleMessage(Message message) {
try {
getConduit(message).prepare(message);
} catch (IOException ex) {
throw new Fault(new org.apache.cxf.common.i18n.Message("COULD_NOT_SEND", BUNDLE), ex);
}

// Add a final interceptor to close the conduit
message.getInterceptorChain().add(ending);
}

public class MessageSenderEndingInterceptor extends AbstractPhaseInterceptor<Message> {
public MessageSenderEndingInterceptor() {
super(Phase.PREPARE_SEND_ENDING);
}

public void handleMessage(Message message) throws Fault {
try {
getConduit(message).close(message);
} catch (IOException e) {
throw new Fault(new org.apache.cxf.common.i18n.Message("COULD_NOT_SEND", BUNDLE), e);
}
}
}

private Conduit getConduit(Message message) {
Exchange exchange = message.getExchange();
Conduit conduit = exchange.getConduit(message);
if (conduit == null
&& (exchange.getOutMessage() != null
|| exchange.getOutFaultMessage() != null)) {
conduit = OutgoingChainInterceptor.getBackChannelConduit(message);
}
return conduit;
}

}

我的问题:如何在我们的项目中重写此类,以便可以自定义内部类的handleMessage?在抛出无法发送消息的 cxf 错误之前,我必须控制错误拦截器...

最佳答案

您可以使用添加到CXF总线的FaultListener。监听器还将捕获 http 异常(例如 404),允许您在将代码引发到调用方法之前执行代码。

例如

public class CxfFaultListenerImpl implements FaultListener{
public boolean faultOccurred(final Exception exception,final String description,final Message message) {

//return false to avoid standard CXF logging of exception
return false;
}
}

Spring CXF配置

<cxf:bus>
<cxf:properties>
<entry key="org.apache.cxf.logging.FaultListener">
<bean id="cxfFaultListener" class="CxfFaultListenerImpl" />
</entry>
</cxf:properties>
</cxf:bus>
