Spring 引導石英：jdbc 表始終初始化

Question

我們在 spring 啟動應用程序中使用石英。 為了存儲工作信息，我使用了 jdbc 商店。 在application.properties文件中，我有以下內容：

spring.quartz.job-store-type=jdbc
spring.quartz.jdbc.initialize-schema=always

但是每次重啟后，表都會被初始化，所有存儲的信息都會丟失。 如果我將 spring.quartz.jdbc.initialize-schema 更改為從不，我在創建表時會遇到異常。

我不想在重啟后刪除石英表數據。 你能幫助我嗎？

問候，斯蒂芬

Answer 1

好吧，根據文檔：

默認情況下，使用 Quartz 庫提供的標准腳本檢測和初始化數據庫。 這些腳本刪除現有表，在每次重新啟動時刪除所有觸發器。 也可以通過設置 spring.quartz.jdbc.schema 屬性來提供自定義腳本。

https://docs.spring.io/spring-boot/docs/2.1.9.RELEASE/reference/html/boot-features-quartz.html

你可以做什么：

1. 修改quartz用於創建表的腳本並刪除drop table語句， create table if not exists...使用create table if not exists... ： https : //github.com/quartz-scheduler/quartz/tree/master/quartz-core/src /main/resources/org/quartz/impl/jdbcjobstore

2. 將語句放入src/main/resources目錄中某處的腳本中（假設您使用的是 maven）

3. 將spring.quartz.jdbc.schema設置為指向您在 #2 中創建的文件

由於您可以使用任何數據庫，因此腳本將是特定於數據庫的。

要么

另一種方法是使用 flyway/liquibase 並使用上述腳本作為這些管理系統的更改（這是我個人會做的）

腳本 -

例如，這里有 mysql（您希望刪除開頭的 drop table 語句並按照上述步驟使用自定義 init 腳本）：

#
# Quartz seems to work best with the driver mm.mysql-2.0.7-bin.jar
#
# PLEASE consider using mysql with innodb tables to avoid locking issues
#
# In your Quartz properties file, you'll need to set
# org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate

Answer 2

我為 Spring Boot 執行了以下步驟以使其完美運行。

我手動創建了名為“quartz”的架構。 然后通過從https://github.com/quartz-scheduler/quartz/tree/master/quartz-core/src/main/resources/org/quartz/impl/jdbcjobstore復制正確的腳本手動創建所有表

然后我在 spring boot 屬性文件中有以下屬性：

spring.quartz.jdbc.initialize-schema=never
spring.quartz.properties.org.quartz.jobStore.tablePrefix=quartz.QRTZ_

我設置的所有其他屬性如下：

#==============================================================
# QUARTZ Configuration
#==============================================================
spring.quartz.job-store-type=jdbc
spring.quartz.jdbc.initialize-schema=never
spring.quartz.properties.org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.PostgreSQLDelegate
spring.quartz.properties.org.quartz.scheduler.instanceId=AUTO
spring.quartz.properties.org.quartz.threadPool.class=org.quartz.simpl.SimpleThreadPool
spring.quartz.properties.org.quartz.threadPool.threadCount=25
spring.quartz.properties.org.quartz.threadPool.threadPriority=5
spring.quartz.properties.org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread=true
spring.quartz.properties.org.quartz.jobStore.misfireThreshold=60000
spring.quartz.properties.org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX
spring.quartz.properties.org.quartz.jobStore.useProperties=false
spring.quartz.properties.org.quartz.jobStore.tablePrefix=quartz.QRTZ_
spring.quartz.properties.org.quartz.jobStore.isClustered=true
spring.quartz.properties.org.quartz.jobStore.clusterCheckinInterval=5000

Answer 3

我也這樣做了。 但是，我使用了解決方案 1)，因為我希望自動創建所有內容。 我在我的資源中創建了一個文件quartz/schema.sql spring.quartz.jdbc.schema: classpath:quartz/schema.sql並設置了屬性spring.quartz.jdbc.schema: classpath:quartz/schema.sql 。

從 application.properties 中刪除以下屬性，您的 Quartz 表數據不會在每次重新啟動時被刪除。 spring.quartz.jdbc.initialize-schema=always
