SpringBoot整合Quartz定时任务（持久化到数据库）

Posted 2023-02-15 zhenghuasheng

1，添加maven依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-quartz</artifactId>
</dependency>

2，配置文件增加配置

spring:
  quartz:
    data-source:
      type: com.alibaba.druid.pool.DruidDataSource
      driverClassName: com.mysql.cj.jdbc.Driver
      url: jdbc:mysql://127.0.0.1:3306/db_quartz?useUnicode=true&characterEncoding=utf8&allowMultiQueries=true
      username: root
      password: 123456
    job-store-type: JDBC
    jdbc:
      initialize-schema: ALWAYS
    properties:
      org:
        quartz:
          overwrite-existing-jobs: true
          scheduler:
            instanceName: clusteredScheduler
            instanceId: AUTO
          jobStore:
            class: org.quartz.impl.jdbcjobstore.JobStoreTX
            driverDelegateClass: org.quartz.impl.jdbcjobstore.StdJDBCDelegate
            tablePrefix: QRTZ_
            isClustered: false
            clusterCheckinInterval: 10000
            useProperties: false
          threadPool:
            class: org.quartz.simpl.SimpleThreadPool
            threadCount: 10
            threadPriority: 5
            threadsInheritContextClassLoaderOfInitializingThread: true

3,新增dataSource配置(因项目中的业务数据源已经配置了dataSource，为了单独区分数据库，配置成单独的数据源)，查看了springboot官网后发现：

在原有dataSource配置类中新增配置：

  private static final String quartz_datasource_prefix = "spring.quartz.data-source";

 /**
     * @QuartzDataSource 注解则是配置Quartz独立数据源的配置
     */
    @Bean
    @QuartzDataSource
    @ConfigurationProperties(prefix = quartz_datasource_prefix)
    public DataSource quartzDataSource()
        return new DruidDataSource();
    

4,创建数据库db_quartz

5,启动应用，会自动初始化sql脚本
