spring:
   #data source connection
  datasource:
    url: jdbc:mysql://localhost:3306/vaquarkhan
    username: rootadmin
    password: root#

Answer 1

The list of special characters in YAML must be escaped.

:, {, }, [, ], ,, &, *, #, ?, |, -, <, >, =, !, %, @, `

You may either quote the string

"root#"

or use back slash.

root\#

Answer 2

I think you can use quotation marks:

spring:
   #data source connection
  datasource:
    url: jdbc:mysql://localhost:3306/vaquarkhan
    username: rootadmin
    password: 'root#'

Answer 3

This could be best way to do it.

  spring:
      #data source connection
        datasource:
          url: jdbc:mysql://localhost:3306/vaquarkhan
          username: rootadmin
          password: 'root#'
