java – 使用Apache CXF发送FastInfoset请求时,我可以在日志中使用XML吗?

我需要在应用程序的日志中提供请求和响应,但Apache CXF发送的请求在FastInfoset(Content-Type:application / fastinfoset)中,这导致请求和响应的日志不可读(因为它是二进制的) ).有没有办法解决这个问题,以便我保留FastInfoset消息(出于性能原因)但是我在日志中得到了正确的XML

这是我现在拥有的CXF配置,如果有帮助的话:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cxf="http://cxf.apache.org/core"
    xsi:schemaLocation="
http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">

    <bean id="logInbound" class="org.apache.cxf.interceptor.LoggingInInterceptor" />
    <bean id="logOutbound" class="org.apache.cxf.interceptor.LoggingOutInterceptor" />

    <cxf:bus>
        <cxf:inInterceptors>
            <ref bean="logInbound" />
        </cxf:inInterceptors>
        <cxf:outInterceptors>
            <ref bean="logOutbound" />
        </cxf:outInterceptors>
        <cxf:outFaultInterceptors>
            <ref bean="logOutbound" />
        </cxf:outFaultInterceptors>
        <cxf:inFaultInterceptors>
            <ref bean="logInbound" />
        </cxf:inFaultInterceptors>
    </cxf:bus>
</beans>

预先感谢您的任何帮助.

最佳答案
我看了LoggingInInterceptor.logInputStream,似乎它不支持fastinfoset.但您可以使用自定义interceptor而不是LoggingInInterceptor和LoggingOutInterceptor来提取有效负载,对其进行解码并记录原始消息.

public class CustomInterceptor extends AbstractPhaseInterceptor<Message> {
    public CustomInterceptor () {
        super(Phase.RECEIVE);
    }

    public void handleMessage(Message message) {
        //Get the message body into payload[] and set a new non-consumed  inputStream into Message
        InputStream in = message.getContent(InputStream.class);
        byte payload[] = IOUtils.readBytesFromStream(in);
        ByteArrayInputStream bin = new ByteArrayInputStream(payload);
        message.setContent(InputStream.class, bin);

        //Decode from FastInfoset and write the payload in your preferred log system
        OutputStream out = System.out 
        decodeFI(in,out);

    }

    public void handleFault(Message messageParam) {
        //Invoked when interceptor fails
        //Exception e = message.getContent(Exception.class);
    }
}

替换XML文件

<bean id="logInbound" class="test.CustomInterceptor" />
<bean id="logOutbound" class="test.CustomInterceptor" />

找到如何解码FastInfoset的示例并不容易.使用DOM和FastInfoset-1.2.12.jar尝试此操作.在这个repo中,您有几个使用sTAX和SAX的示例

public void decodeFI(InputStream in, OutputStream out) throws Exception{
    DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
    Document doc = docBuilder.newDocument();

    DOMDocumentParser parser = new DOMDocumentParser();
    parser.parse(doc, in);

    // write the content into xml file
    TransformerFactory transformerFactory = TransformerFactory.newInstance();
    Transformer transformer = transformerFactory.newTransformer();
    DOMSource source = new DOMSource(doc);
    StreamResult result = new StreamResult(out);
    transformer.transform(source, result);
}
