Debug/Logging Headers, Properties, Payload Body using Groovy Scripts

This post show Groovy scripting to read and log all header, properties in message log, and payload body as attachment, then can be viewed in Monitoring Message Processing Log, for troubleshooting and debug purpose.
Reuse previous iFlow, the completed iFlow is like below. Added 2 steps before and after message mapping step, name it log01 and log02 respectively.

Create script called logger.groovy:

import com.sap.gateway.ip.core.customdev.util.Message;
import java.util.HashMap;
import java.text.SimpleDateFormat;
import java.util.Date;
def Message log01(Message message) {processData("log01_before_mapping", message);}
def Message log02(Message message) {processData("log02_after_mapping", message);}
def Message log03(Message message) {processData("log03", message);}
def Message log04(Message message) {processData("log04", message);}
def Message log05(Message message) {processData("log05", message);}
def Message log06(Message message) {processData("log06", message);}
def Message log07(Message message) {processData("log07", message);}
def Message log08(Message message) {processData("log08", message);}
def Message log09(Message message) {processData("log09", message);}
def Message log10(Message message) {processData("log10", message);}
def Message processData(String prefix, Message message) {
	def headers = message.getHeaders();
	def body = message.getBody(java.lang.String) as String;
	def messageLog = messageLogFactory.getMessageLog(message);
	for (header in headers) {
	   messageLog.setStringProperty("header." + header.getKey().toString(), header.getValue().toString())
	}
	for (property in properties) {
	   messageLog.setStringProperty("property." + property.getKey().toString(), property.getValue().toString())
	}
    if(messageLog != null){
        messageLog.addAttachmentAsString(prefix, body, "text/plain");
     }
    return message;
}

At log01 and log02 steps, put value in Name and Script Function as well:

After test run, will able to see 2 attachments:

All header and properties is showing at “Log” tab:

Attachment are showing and 2nd and 3rd tabs:

Keep on exploring 🙂
