一、概述

普通Java工程这里指非spring工程，主要指一些系统资源监控程序、数据日志清理程序等，需要保持依赖简单，执行文件体积微小方便部署，这些程序需要需要跟数据库交互，例如需要将监控数据持久化到db、连接数据库清理过期数据等。

二、常规做法

1. 数据库配置分离

普通Java工程配置文件一般采用properties，典型的配置文件如下：
jdbc.properties

jdbc.driver   = com.mysql.cj.jdbc.Driver
jdbc.url      = jdbc:mysql://127.0.0.1:3306/jdbc?useSSL=false&useUnicode=true&characterEncoding=utf-8&createDatabaseIfNotExist=true
jdbc.username = root
jdbc.password = root123

2. 代码引用配置

        ResourceBundle config = ResourceBundle.getBundle("jdbc");
        PoolProperties p = new PoolProperties();
        p.setUrl(config.getString("jdbc.url"));
        p.setDriverClassName(config.getString("jdbc.driver"));
        p.setUsername(config.getString("jdbc.username"));
        p.setPassword(config.getString("jdbc.password"));

3. 编写启动类

启动类main方法，一般使用定时任务线程池，以保证程序一直运行
核心代码：

 ScheduledExecutorService service = new ScheduledThreadPoolExecutor(1);
  service.scheduleAtFixedRate(() -> { 
       doSomething(); // 业务方法
   }, 0, 60, TimeUnit.SECONDS);

4. 支持打包成可执行包

具体参考普通Java工程可执行JAR两种打包方式探讨

5. 支持可执行包打包成docker镜像

具体参考：容器镜像生成记

6. docker运行

在编排文件目录执行 docker-compose up -d

docker-compose.yml

version: '3.7'
services:
  java-with-docker:
    image: registry.cn-shanghai.aliyuncs.com/00fly/java-with-docker:0.0.1
    container_name: java-with-docker
    deploy:
      resources:
        limits:
          cpus: '1.0'
          memory: 64M
        reservations:
          cpus: '0.05'
          memory: 64M
    restart: on-failure
    logging:
      driver: json-file
      options:
        max-size: '5m'
        max-file: '1'

三、存在问题分析

上面的做法存在最大的问题是：

数据库配置固定在内部配置文件jdbc.properties中
维护麻烦，如果是通用的需要，每换一套环境，需要重新跑流程，包括打包可执行包和镜像打包。

四、改进措施

在springboot 工程中，我们支持数据源配置在docker-compose.yml中的environment配置
典型例子如下：

version: '3.8'
services:
  springboot-dbutils:
    image: 00fly/springboot-dbutils:0.0.1
    container_name: springboot-dbutils
    deploy:
      resources:
        limits:
          cpus: '0.80'
          memory: 400M
        reservations:
          cpus: '0.05'
          memory: 200M
    ports:
    - 80:8080
    environment:
    - SPRING_DATASOURCE_URL=jdbc:mysql://127.0.0.1:3306/dbutils?useSSL=false&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&autoReconnect=true
    - SPRING_DATASOURCE_USERNAME=user
    - SPRING_DATASOURCE_PASSWORD=password123
    restart: on-failure
    logging:
      driver: json-file
      options:
        max-size: 5m
        max-file: '1'

同理，我们也希望普通java也支持如下编排文件中的environment 变量

1. 包含environment 变量的编排文件

docker-compose.yml

version: '3.7'
services:
  java-with-docker:
    image: registry.cn-shanghai.aliyuncs.com/00fly/java-with-docker:0.0.1
    container_name: java-with-docker
    deploy:
      resources:
        limits:
          cpus: '1.0'
          memory: 64M
        reservations:
          cpus: '0.05'
          memory: 64M
    restart: on-failure
    environment:
    - JDBC_URL=jdbc:mysql://192.168.15.202:3306/jdbc?useSSL=false&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&autoReconnect=true
    - JDBC_USERNAME=test
    - JDBC_PASSWORD=test123
    - JDBC_DRIVER=com.mysql.cj.jdbc.Driver
    logging:
      driver: json-file
      options:
        max-size: '5m'
        max-file: '1'

2. 修改读取配置文件方式

将原来读取jdbc.properties的配置文件的方式修改为如下：

        //docker环境下优先使用docker-compose中environment值
        Map<String, String> env = System.getenv();
        ResourceBundle config = ResourceBundle.getBundle("jdbc");
        String url = StringUtils.defaultIfBlank(env.get("JDBC_URL"), config.getString("jdbc.url"));
        String userName = StringUtils.defaultIfBlank(env.get("JDBC_USERNAME"), config.getString("jdbc.username"));
        String passWord = StringUtils.defaultIfBlank(env.get("JDBC_PASSWORD"), config.getString("jdbc.password"));
        dataSource.setUrl(url);
        dataSource.setUser(userName);
        dataSource.setPassword(passWord);

3. 为什么可以这样做

其实，这说明了：在docker-compose.yml配置的environment 值，均会被读取到System.getenv() 中

五、运行效果

1. 本地windows运行
