Quartz / MYSQL ResourcePool无法从其主工厂或源获取资源

Question

尝试将Quartz调度程序集成到spring应用程序中时，我尝试使用org.quartz.impl.jdbcjobstore.JobStoreTX添加持久性 与mysql上的数据存储。

org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
org.quartz.jobStore.useProperties = false

org.quartz.jobStore.dataSource = WDS

org.quartz.jobStore.tablePrefix = QRTZ_

org.quartz.jobStore.dontSetAutoCommitFalse = false
org.quartz.dataSource.WDS.driver = com.mysql.jdbc.Driver
org.quartz.dataSource.WDS.debugUnreturnedConnectionStackTraces = true
org.quartz.dataSource.WDS.URL = jdbc:mysql://url:port/DB?useSSL=true&verifyServerCertificate=false
org.quartz.dataSource.WDS.user = xxx
org.quartz.dataSource.WDS.password = xxx
org.quartz.dataSource.WDS.maxConnections = 4

以下是我得到的错误

Answer 1

您提到的问题可能是由多种原因引起的。首先检查数据库版本。我有最新版本的mysql（8.0.11）的问题，默认情况下采用身份验证类型＆＃34; caching_sha2_password ＆＃34;。

更改为mysql版本5.7解决了我的问题，默认情况下将身份验证类型设置为＆＃34; 标准＆＃34;。

N.B不要忘记添加所需的管理角色和架构特权
