Question

I'm trying to setup a webapp with maven2 managed dependcies. Here my pom.xml

What is wrong with my setup?

Answer 1

Include the slf4j-api in your dependencies:

<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-api</artifactId>
  <version>1.5.8</version>
</dependency>

Exclude the commons-logging dependency for minimum one of your declared spring dependencies and provide the slf4j facade for commons-logging:

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-context</artifactId>
  <version>3.0.2.RELEASE</version>
  <exclusions>
     <exclusion>
       <groupId>commons-logging</groupId>
       <artifactId>commons-logging</artifactId>
     </exclusion>
  </exclusions>
</dependency>
<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>jcl-over-slf4j</artifactId>
  <version>1.5.8</version>
  <scope>runtime</scope>
</dependency>

Include the log4j dependency for your logging together with the slf4j facade:

<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-log4j12</artifactId>
  <version>1.5.8</version>
  <scope>runtime</scope>
</dependency>
<dependency>
  <groupId>log4j</groupId>
  <artifactId>log4j</artifactId>
  <version>1.2.14</version>
  <scope>runtime</scope>
</dependency>

A great blog post for further reading about logging with SLF4J and Spring can be found in the SpringSource Team blog under http://blog.springsource.com/2009/12/04/logging-dependencies-in-spring/.
