Properties in my application.properties are grayed out. Build success but Driver com.mysql.cj.jdbc.Driver claims to not accept jdbcUrl

Question

Working in Intellij. I'm trying to see the data stored in my DB. When I go to my application.properties to configure the connection all " spring.(...) " lines are grayed out. My application.properties resource directory is marked as resource root

#GENERAL
server.port=8080

#DATABASE
spring.datasource.url=jdbc.mysql://localhost/webservice?useSSL=false
spring.datasource.dbname=webservice
spring.datasource.username=root
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

This is my pom.xml file:

Answer 1

I managed to fix it. The actual problem was a typo, instead of: spring.datasource.url=jdbc.mysql://localhost/webservice?useSSL=false it shoud have been: spring.datasource.url=jdbc:mysql://localhost/webservice?useSSL=false

To take away the grey i followed the advise on https://intellij-support.jetbrains.com/hc/en-us/community/posts/206858715-Properties-editor-reporting-Unused-property-for-all-entries
