1.创建springBoot项目

2.引入Quartz相关依赖

<dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-jdbc</artifactId>
        <version>4.3.18.RELEASE</version>
    </dependency>
    
    <dependency>
        <groupId>org.quartz-scheduler</groupId>
        <artifactId>quartz</artifactId>
        <version>2.2.3</version>
    </dependency>
    <dependency>
        <groupId>org.quartz-scheduler</groupId>
        <artifactId>quartz-jobs</artifactId>
        <version>2.2.3</version>
    </dependency>

3 在resources目录创建quartz.properties文件

org.quartz.scheduler.instanceName = MyScheduler
    org.quartz.scheduler.instanceId = AUTO
    org.quartz.scheduler.rmi.export = false
    org.quartz.scheduler.rmi.proxy = false
    org.quartz.scheduler.wrapJobExecutionInUserTransaction = false
    
    #线程池配置
    org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
    org.quartz.threadPool.threadCount = 10
    org.quartz.threadPool.threadPriority = 5
    org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = true
    
    ##持久化配置
    #org.quartz.jobStore.misfireThreshold = 50000
    #org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
    ##支持集群
    #org.quartz.jobStore.isClustered = true
    #org.quartz.jobStore.useProperties:true
    #org.quartz.jobStore.clusterCheckinInterval = 15000
    ##使用weblogic连接Oracle驱动
    #org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.oracle.weblogic.WebLogicOracleDelegate
    ##org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
    #org.quartz.jobStore.tablePrefix = QRTZ_
    #org.quartz.jobStore.dataSource = qzDS
    ##数据源连接信息，quartz默认使用c3p0数据源可以被自定义数据源覆盖
    #org.quartz.dataSource.qzDS.driver = oracle.jdbc.driver.OracleDriver
    #org.quartz.dataSource.qzDS.URL = jdbc:oracle:thin:@localhost:1521/XE
    #org.quartz.dataSource.qzDS.user = root
    #org.quartz.dataSource.qzDS.password = 123456
    #org.quartz.dataSource.qzDS.maxConnections = 10

4.QuartzConfiguration

            //获取配置属性
            PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
            propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));
            //在quartz.properties中的属性被读取并注入后再初始化对象
            propertiesFactoryBean.afterPropertiesSet();

         */
        @Bean(name = "scheduler")
        public Scheduler scheduler() throws IOException {
            return schedulerFactoryBean().getScheduler();
        }
    }

    @Component

        @Override

            //调用父类的方法
            Object jobInstance = super.createJobInstance(bundle);
            //进行注入
            capableBeanFactory.autowireBean(jobInstance);
            return jobInstance;
        }
    }

    }
