Quartz属性文件传入环境变量

我正在尝试将环境变量添加到我的石英属性文件中，但它没有正确加载。

这是我的quartz.properties

  org.quartz.scheduler.instanceName: scheduler
  org.quartz.scheduler.instanceId: AUTO
  org.quartz.scheduler.skipUpdateCheck: true
  org.quartz.threadPool.class: org.quartz.simpl.SimpleThreadPool
  org.quartz.threadPool.threadCount: 10
  org.quartz.threadPool.threadPriority: 5
  org.quartz.jobStore.misfireThreshold: 60000
  org.quartz.jobStore.class: org.quartz.impl.jdbcjobstore.JobStoreTX
  org.quartz.jobStore.driverDelegateClass: org.quartz.impl.jdbcjobstore.PostgreSQLDelegate
  org.quartz.jobStore.useProperties: false
  org.quartz.jobStore.dataSource: myDS
  org.quartz.jobStore.tablePrefix: QRTZ_
  org.quartz.jobStore.isClustered: true
  org.quartz.dataSource.myDS.driver: org.postgresql.Driver
  org.quartz.dataSource.myDS.URL: ${APP_JDBC_URL:-jdbc:postgresql://localhost:5432/db}
  org.quartz.dataSource.myDS.user:  ${APP_JDBC_USER:-user}
  org.quartz.dataSource.myDS.password: ${APP_JDBC_PASSWORD:-pass}
  org.quartz.dataSource.myDS.maxConnections: 5
  org.quartz.dataSource.myDS.validationQuery: select 1

例外：

ERROR [2018-03-13 21:11:13,958] org.quartz.impl.jdbcjobstore.JobStoreTX: ClusterManager: Error managing cluster: Failed to obtain DB connection from data source 'myDS': java.sql.SQLException: Connections could not be acquired from the underlying database!

quartz.properties 文件按照以下约定读取环境变量：$@environment_variable_name.

例如，这正在我的应用程序上运行：

org.quartz.threadPool.threadCount=$@QUARTZ_THREAD_COUNT

在您的情况下，您应该能够使用：

org.quartz.dataSource.myDS.URL=$@APP_JDBC_URL
org.quartz.dataSource.myDS.user=$@APP_JDBC_USER
org.quartz.dataSource.myDS.password=$@APP_JDBC_PASSWORD
