I'm new to Java/Spring and whenever I compile and run a package or class in Spring Tool Suite, I will see the output, but STS will also included a bunch of other information that I'm really not concerned about. How can I make it so that STS only shows me the output and relevant errors and not all the extraneous info like the stuff below:

Apparently you need to change the default logger threshold. This can be done in your application.properties or else directly to your logger config file if you are using any third party logging libraries.
The allowed levels are : ERROR, WARN, INFO, DEBUG, or TRACE.
For Spring Boot the defaults are :
ROOT :
logging.level.root=ERROR
Spring WEB :
logging.level.org.springframework.web: ERROR
In case you are using Hibernate :
logging.level.org.hibernate: ERROR
