positive.code: * If `spring-cloud-sleuth-stream` then the app will generate and collect traces via Spring Cloud Stream. Your app automatically becomes a producer of tracer messages that are sent over your broker of choice (e.g. RabbitMQ, Apache Kafka, Redis).
  
  If using Zipkin or Stream, configure the percentage of spans exported using `spring.sleuth.sampler.percentage` (default 0.1, i.e. 10%).

  ==== Importing into Intellij
  Spring Cloud projects use annotation processing, particularly Lombok, which requires configuration
  or you will encounter compile problems. It also needs a specific version of maven and a profile
  enabled. Intellij 14.1+ requires some configuration to ensure these are setup properly.
  
   1. Click Preferences, Plugins. *Ensure Lombok is installed*
   2. Click New, Project from Existing Sources, choose your spring-cloud-sleuth directory
   3. Choose Maven, and select Environment Settings. *Ensure you are using Maven 3.3.3*
   4. In the next screen, *Select the profile `spring`* click Next until Finish.
   5. Click Preferences, "Build, Execution, Deployment", Compiler, Annotation Processors. *Click Enable Annotation Processing*
   6. Click Build, Rebuild Project, and you are ready to go!
  
  ==== Importing into other IDEs
  Maven is well supported by most Java IDEs. Refer to you vendor documentation.
