Describe your question

As i excute the bootRun, and i input a command, it went wrong.

Did i miss some configration about connecting the database or something? Please tell me how to solve this problem.

ensure your application.yml looks like this

spring:
  datasource:
    url: jdbc:postgresql://localhost:5432/sustc  # change this to your own jdbc url
    username: sustc  # change this to your own username (avoid using a superuser)
    password: sustc  # change this to your own password
