我对docker完全陌生。现在我有了这个springmvc应用程序（在wildfly上运行），它使用了一个mysql数据库，我想对它进行dockerize。我确实创建了一个docker文件，其内容如下

FROM jboss/wildfly

# ADD nummerreeks.war /opt/jboss/wildfly/standalone/deployments/

ADD test.war /home/Docker/app

# Set the working directory to /app

WORKDIR /app

# Copy the current directory contents into the container at /app

ADD . /app

以及docker compose文件，如下所示：

version: '2'
services:
  database:
    image: mysql:latest
    ports:
      - 3306
    environment:
      MYSQL_ROOT_PASSWORD: admin
      MYSQL_USER: test
      MYSQL_PASSWORD: admin
      MYSQL_DATABASE: dbpass
  wildfly:
    image: bitnami/wildfly:latest
    ports:
      - '8080:8080'
      - '9990:9990' 
    links:
      - app
    volumes_from:
      - app
  app:
    image: test/demo
    volumes:
      - wars:/opt/jboss/wildfly/standalone/deployments/
    links:
      - database
volumes:
  wars:
    driver: local

现在使用以下命令运行时：

docker run -t -p 8080:8080 --name dockerapp test

我有个db例外，

org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is java.sql.SQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.

    at java.lang.reflect.Method.invoke(Method.java:498)

我相信它是从应用程序中db.config文件的db connection值读取db config，而不是从docker compose文件读取。
有人指出我做错了什么吗？
