我想为每个请求添加一些相关性ID,并将其自动显示在日志消息中。如何自动为<logger />
及其变体添加额外的值?
我努力了:
Spring aop切成LoggerMessageProcessor.process(MuleEvent event)
,但该事件不包含记录的消息
Spring aop切成LoggerMessageProcessor.setMessage(String msg)
会包含消息,但是由于某种原因未调用该方法
最佳答案
<flow name="add-correlation-id">
<scripting:component doc:name="Script">
<scripting:script engine="groovy">
<![CDATA[
String correlationId=message.getInboundProperty('x-request-id');
if(correlationId==null || correlationId.length() == 0){
correlationId = java.util.UUID.randomUUID().toString();
}
message.setSessionProperty('requestID',correlationId);
org.apache.log4j.MDC.put('x-request-id',correlationId);
