我已经创建了一个从一个Spring的应用程序,但有一个错误,它不能访问mysql数据库,我有问题解决这个Docker图像。
我使用Dockerfile创建了一个映像

FROM openjdk:17-jdk-alpine
EXPOSE 8080
ARG JAR_FILE=./sample-service.jar
ADD ${JAR_FILE} app.jar
ENTRYPOINT ["java","-jar","/app.jar"]

创建图像后,我创建了docker-compose.yml,这是我的docker-compose.yml:

version: "3"
services:
  sample-service:
    image: v2stechit/sample-service
    ports:
        - "8080:8080"                      
    restart: always                            
    environment:
        SPRING_DATASOURCE_URL: jdbc:mysql://localhost:3306/buddyto_mstr_local?useSSL=false
        SPRING_DATASOURCE_USERNAME: root
        SPRING_DATASOURCE_PASSWORD: root
    networks:
      - spring-mysql
    depends_on:
      - mysqldb
 
  mysqldb:
    image: mysql:8.0.29
    networks:
      - spring-mysql
    environment:
      - MYSQL_ROOT_PASSWORD=root
      - MYSQL_DATABASE=buddyto_mstr_local
      - MYSQL_USERNAME=root
      - MYSQL_PASSWORD=root
   ports:
      - 3306:3306
networks:
  spring-mysql:

但它没有在浏览器中打开,所以我检查了日志,得到了这个:
以下是Spring Docker容器日志:https://pastebin.com/raw/pjiscq4T
下面是mysql日志:

我该如何解决这个问题?
我试着为mysql使用空的password环境变量。
尝试更改数据库名称,将mysql版本更改为5.6、8和8.0.29
我不知道下一步该做什么。
我期待着Spring的应用程序与mysql链接

docker中的localhost将不会解析为服务器的localhost。相反,您需要指定mysql服务的名称mysqldb
于是这就变成:SPRING_DATASOURCE_URL: jdbc:mysql://msqldb:3306/buddyto_mstr_local?useSSL=false
您也可以尝试给出运行Docker的服务器的IP,而不是mysqldb

我终于修复了它。我做了一些清理配置文件,它是自动修复。非常感谢。
