Stop Apache CXF logging binary data of MultipartBody attachments

问题

I need to stop CXF from logging the binary data of attachments in a MultipartBody object (which is being thrown out by the AbstractLoggingInterceptor in the Outbound Message). When I add my LoggingInInterceptor, I am setting setShowBinaryData to false, but this doesn't seem to stop binary data within a multipart message from being logged.

I am unsure whether I need to create a custom loggingInInterceptor, or whether there is a way of configuring the existing interceptors to truncate any binary data it finds. Stopping it logging the MultipartBody response entirely, or truncating the data are both acceptable solutions.

回答1:

showBinaryContent by default is false, however binary data gets logged based on content type, Currently if your content type is not any of the following; the binary data would be logged.

static {
        BINARY_CONTENT_MEDIA_TYPES = new ArrayList<String>();
        BINARY_CONTENT_MEDIA_TYPES.add("application/octet-stream");
        BINARY_CONTENT_MEDIA_TYPES.add("image/png");
        BINARY_CONTENT_MEDIA_TYPES.add("image/jpeg");
        BINARY_CONTENT_MEDIA_TYPES.add("image/gif");
    }

Say your content type is application/zip, you can Create Custom Interceptor and override isBinaryContent as shown below

import org.apache.commons.lang3.StringUtils;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.interceptor.LoggingMessage;

public class KPLogOutInterceptor extends LoggingOutInterceptor {

    @Override
    public boolean isBinaryContent(String contentType) {
        return contentType != null && (BINARY_CONTENT_MEDIA_TYPES.contains(contentType)|| "application/zip".equals(contentType);
    }
}

Another way without using content type is as shown below.

import org.apache.commons.lang3.StringUtils;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.interceptor.LoggingMessage;

public class KPLogOutInterceptor extends LoggingOutInterceptor {

    @Override
    protected String formatLoggingMessage(LoggingMessage loggingMessage) {

        return removePayload(loggingMessage.toString()); 
    }


    private String removePayload(String str){

        StringBuilder builder = new StringBuilder(str);
        if (str.indexOf("Payload:") + 9 > 8) {
            builder.setLength(builder.indexOf("Payload:") + 8);
            builder.append(" <content skipped>\n");
            builder.append(StringUtils.repeat('-', 25));
        }
        return builder.toString();  
    }
}
