@SpringBootApplication cannot be resolved to a type In STS
Run bellow commands from command line
mvn clean dependency:tree
mvn clean compile
select project and do a maven->update This solved my problem
Just change your spring boot version into 1.5.6 from 1.5.8. trust me i have tried every other solution but only this solution worked for me.
Go to your maven repository directory
For windows on below path
C:\Users\YourUser\.m2\repository\org\springframework\boot
Then delete spring-boot-autoconfigure
folder.
Now go to eclipse Right click on project -> Maven -> Update Project
.
This solved the problem for me.
