# xxl-job-executor-sample-nutzboot
|
||||
|
||||
用NutzBoot作为xxl-job-executor的示例
|
||||
|
||||
## 文件介绍
|
||||
|
||||
* MainLauncher.java NutzBoot启动类, 其中的init方法,扫描/加载/注册ioc容器内的IJobHandler
|
||||
* XxlJobConfig.java 读取配置信息,声明XxlJobExecutor对象
|
||||
* ShardingJobHandler.java和DemoJobHandler.java 2个示例IJobHandler实现类
|
||||
|
||||
## 环境要求
|
||||
|
||||
* JDK8u112 以上
|
||||
|
||||
