定时器quartz工具类

一、gradle配置

　　// https://mvnrepository.com/artifact/org.quartz-scheduler/quartz
    compile group: 'org.quartz-scheduler', name: 'quartz', version: '2.2.3'
    // https://mvnrepository.com/artifact/org.quartz-scheduler/quartz-jobs
    compile group: 'org.quartz-scheduler', name: 'quartz-jobs', version: '2.2.3'
