how to run spring boot with mysql by docker compose?

Question

I haven't been able to find a solution to this error for over a week.

applicatio.yml

spring:
  jpa:
    hibernate:
      ddl-auto: create-drop
    show-sql: true
    database-platform: org.hibernate.dialect.MySQL8Dialect
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://test-mysql:3306
    username: root
    password: 1234

and docker-compose yml.

version: "3.7"

services:
  test-mysql:
    container_name: test-mysql
    image: mysql
    environment:
      MYSQL_ROOT_PASSWORD: 1234
    volumes:
      - ./data.sql:/docker-entrypoint-initdb.d/data.sql
    ports:
      - "3306:3306"
    networks:
      - test-mysql
  app:
    build: .
    ports:
      - "8080:8080"
    depends_on:
      - test-mysql
    container_name: app
    networks:
      - test-mysql

networks:
  test-mysql:
 

data.sql

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';

If you run the script like this, an error occurs when running the Spring Boot application. I can't seem to connect to mysql, but I'm not sure what the problem is.

For reference, I use lima instead of docker desktop, but I don't know if this is the cause.
