Spring-Boot logging with log4j2?

Question

I'm using spring-boot-starter, and would like to configure log4j2.xml to log asynchron + different content to different logfiles.

I created the log4j2 file, but Spring still uses the spring-boot default logging. How can I switch the logging?

Answer 1

I've a better way:

1. Exclude logback logger:

   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter</artifactId>
       <exclusions>
           <exclusion>
               <groupId>org.springframework.boot</groupId>
               <artifactId>spring-boot-starter-logging</artifactId>
           </exclusion>
       </exclusions>
   </dependency>
   

2. Add log4j2 boot starter:

   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-log4j2</artifactId>
   </dependency>
