Class JsonlLogWriter

java.lang.Object

org.jpos.util.BaseLogEventWriter

org.jpos.util.JsonlLogWriter

All Implemented Interfaces:

Configurable, LogEventWriter

public class JsonlLogWriter
extends BaseLogEventWriter
implements Configurable

JSONL (one JSON object per line) LogEventWriter with built-in PCI protection.

When serializing ISOMsg objects in LogEvent payloads, sensitive fields are masked or wiped inline — no upstream ProtectedLogListener required.

Configuration properties (same convention as ProtectedLogListener):

• protect — space-separated field numbers to mask via ISOUtil.protect(String) (default: "2")
• wipe — space-separated field numbers to replace with [WIPED] (default: "35 45 48 52 55")

Output is suitable for jq, Filebeat, and Elasticsearch ingestion.

Since:

3.0.0
