Log4j2 including library name in stacktrace

Question

I just started using of log4j2. But i found that log4j2 including library name in stacktrace. How can i disable that?

Here is an example:

java.lang.NullPointerException
    at com.sev.controllers.UserController.login(UserController.java:35) ~[UserController.class:?]
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:1.8.0_31]

Im talking about that name in [] braces.

Here is my log4j config

<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
    <Appenders>
        <Console name="STDOUT" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n"/>
        </Console>
    </Appenders>
    <Loggers>
        <Logger name="org.apache.log4j.xml" level="INFO"/>
        <Logger name="org.hibernate" level="INFO"/>
        <Logger name="org.springframework" level="INFO"/>
        <Root level="debug">
            <AppenderRef ref="STDOUT"/>
        </Root>
    </Loggers>
</Configuration>

And here is my versions:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-log4j2</artifactId>
    <version>1.2.5.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
    <version>2.3</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
    <version>2.3</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-slf4j-impl</artifactId>
    <version>2.3</version>
</dependency>

Forget to mention that my app is spring-boot based.

Answer 1

I think it's better: [...%m%n%ex]

Answer 2

Your configuration's PatternLayout pattern does not contain an explicit exception converter. Log4j will provide a default which is %xEx. This includes the jar file etc.

You can change this by explicitly specifying setting the simple %ex converter. So your pattern ends in ...%m%ex%n.
