我正在尝试创建Docker容器，我尝试为MySql设置1，为Spring io设置另一个。DB容器运行正常，但Sping Boot 容器在某个点出现并退出。我搜索并尝试了许多方法，但似乎无法解决它，我得出的结论是，似乎数据库环境或www.example.com有问题aplication.properties，或者可能有问题别的地方。如果有人能指导我找到解决办法，我将非常感激。
application.properties:

spring.datasource.url=jdbc:mysql://DB_containerfile:3306/phase2?useSSL=false&allowPublicKeyRetrieval=true&serverTimezone=UTC
spring.datasource.username=testuser
spring.datasource.password= testuser@123
spring.jpa.hibernate.ddl-auto=update
spring.datasource.driver-class-name= com.mysql.cj.jdbc.Driver

停靠文件：

FROM openjdk:17
ADD target/springboot-crud-api-0.0.1-SNAPSHOT.jar app.jar
ENTRYPOINT ["java","-jar","app.jar"]

docker-compose.yml:

version: '3.8'

services:
DB_containerfile:
image: mysql:latest
container_name: DB_containerfile
environment:
- MYSQL_ROOT_PASSWORD=////////////
- MYSQL_DATABASE=phase2
- MYSQL_USER=testuser
- MYSQL_PASSWORD=testuser@123

backend_containerfile:
image: backend_image
container_name: backend_containerfile
ports:
- 8080:8080
build:
context: ./
dockerfile: Dockerfile
depends_on:
- DB_containerfile

注意：我将在cmd“mysql -u root -p”上写入此命令时输入的密码分配给了MYSQL_ROOT_PASSWORD

我尝试过：1）我试过Docker卷修剪。2）我试过删除

- MYSQL_USER=testuser
- MYSQL_PASSWORD=testuser@123
  spring.datasource.username=testuser
  spring.datasource.password= testuser@123\`

而且只跟

- MYSQL_ROOT_PASSWORD=////////////

3）我两个都试过了

spring.datasource.driver-class-name= com.mysql.cj.jdbc.Driver spring.datasource.driver-class-name= com.mysql.jdbc.Driver

4）我在spring.datasource.url中设置了allowPublicKeyRetrieval=true，我尝试了很多其他方法，但结果都是一样的。
抱歉，问了这么长的问题，但我真的想自己解决这个问题，但现在我需要别人的见解。谢谢你。
