Writing Application Logs

The Basics

As outlined in the Introduction, we do support applications that write logs using the slf4j API in combination with one of the API implementations logback or log4j2.

So you need to decide

• which logging implementation you use,
• set your Maven dependencies, and
• adjust your logging configurations accordingly

We'll give details in the following sub sections

Using logback

Maven Dependencies

As we're talking about application logs in this section, we're only using the core feature and link it with the logback implementation. Since the core feature is pulled as a dependency in the logback implementation, we'll end up with a dependency list like this:

  <!-- pulls cf-java-logging-support-core feature -->
  <dependency>
    <groupId>com.sap.hcp.cf.logging</groupId>
    <artifactId>cf-java-logging-support-logback</artifactId>
    <version>${cf-logging-version}</version>
  </dependency>
  <!-- logback -->
  <dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.1.3</version>
  </dependency>
