[jira] [Created] (LOG4J2-2967) NullPointerException when used the
messageParameter resolver of the JsonLayoutTemplate
Diego Pettisani created LOG4J2-2967:
---------------------------------------
Summary: NullPointerException when used the messageParameter resolver of the JsonLayoutTemplate
Key: LOG4J2-2967
URL: https://issues.apache.org/jira/browse/LOG4J2-2967
Project: Log4j 2
Issue Type: Bug
Components: Layouts
Affects Versions: 2.14.0
Environment: * JDK 8
* Spring Boot 2.3.4
* Log4j2 2.14.0
Reporter: Diego Pettisani
I have used the new {{messageParameter}} resolver of the JsonLayoutTemplate introduced with log4j2 v2.14.0 (see LOG4J2-2936).
I configured a Spring Boot app with the following lo4j2.xml:
{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
<Appenders>
<Console name="console" target="SYSTEM_OUT">
<JsonTemplateLayout eventTemplateUri="classpath:MyCustomLayout.json" />
</Console>
</Appenders>
<Loggers>
<Root level="info">
<AppenderRef ref="console" />
</Root>
</Loggers>
</Configuration>
{code}
and the following custom JSON template layout:
{code:json}
{
"@timestamp": {
"$resolver": "timestamp",
"pattern": {
"format": "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'",
"timeZone": "UTC"
}
},
"level": {
"$resolver": "level",
"field": "name"
},
"message": {
"$resolver": "message",
"stringified": true
},
"thread": {
"$resolver": "thread",
"field": "name"
},
"logger": {
"$resolver": "logger",
"field": "name"
},
"labels": {
"$resolver": "mdc",
"flatten": true,
"stringified": true
},
"error.type": {
"$resolver": "exception",
"field": "className"
},
"error.message": {
"$resolver": "exception",
"field": "message"
},
"error.stack_trace": {
"$resolver": "exception",
"field": "stackTrace",
"stringified": true
},
"p0": {
"$resolver": "messageParameter",
"index": 0,
"stringified": true
},
"p1": {
"$resolver": "messageParameter",
"index": 1,
"stringified": true
},
"p2": {
"$resolver": "messageParameter",
"index": 2,
"stringified": true
},
"p3": {
"$resolver": "messageParameter",
"index": 3,
"stringified": true
}
{code}
When the app starts the following {{NullPointerException}} occurs:
{code}
