Spring Boot boot process
The Spring Boot series-5 minutes to build an app-explains how to quickly create a spring boot project and run it. Although the steps are simple and the develope
avoid this much dependencies definitions in our build files? The solution is Spring Boot Starter component.Spring Boot Starter component combines all related jars to single jar file So, we can add only jar file dependency t o Our build files. Instead of adding above 4 jars files to our build file, we need to add one and only one jar file: "
see the monitoring information for a particular example.Sample codeEmail alertsSpring Boot Admin Shows all the application information in the micro-service in the background, so it is very convenient for us to monitor and govern the micro-service overall.

Typically used when retrieving data asynchronously, after using @requestmapping, the return valueusually resolves to the jump path, plus @responsebody after the return result will not be resolved to the jump path, but directly written to the HTTP response body
