Getting users from database

[elenadobrescu21]

I am trying to get users from a database.
I have added the following code to the application.yml file,
hibernate:
# possible values: validate | update | create | create-drop
ddl-auto: create-drop
datasource:
url: jdbc:mysql://localhost:3306/user_management
username: root
password:
driver-class-name: com.mysql.jdbc.Driver`

I have a database with one user, but when I enter the credentials in postman I get the following exception "java.lang.StackOverflowError".
How should I modify the code to make it work?

Here my working application.yml with MySQL database:

spring:
  jackson:
    serialization:
      INDENT_OUTPUT: true
  opa: 
    show-sql: true
    properties:
      hibernate:
        dialect: org.hibernate.dialect.MySQL5Dialect
    hibernate: 
      ddl-auto: update
      naming-strategy: org.hibernate.cfg.ImprovedNamingStrategy

  datasource:
    url: jdbc:mysql://localhost/<your database name>
    username: <your database username>
    password: <your database password>
    driver-class-name: com.mysql.jdbc.Driver
    testWhileIdle: true
    validationQuery: SELECT 1

Hope helps u.
