Deployment on Tomcat: Constraint violation when resolving method “org.slf4j.impl.StaticLoggerBinder.getLoggerFactory()Lorg/slf4j/ILoggerFactory;”

Question

I\'m deploying Shibboleth IdP 3.1.1 on Tomcat 8.0.22, but I receive this error:

SEVERE [http-nio-8080-exec-13] org.apache.catalina.core.StandardContext.listenerS         


        

Answer 1

If you are using spring-boot-starter-web-1.5.1.RELEASE.jar,then you need to exclude jul-to-slf4j-1.7.22.jar,jcl-over-slf4j-1.7.22.jar.These two jar have conflict slf4j-api.

  maven-war-plugin
  2.6
          
            
    WEB-INF/lib/jcl-over-slf4j-1.7.22.jar,WEB-INF/lib/jul-to-slf4j-1.7.22.jar
