接入

1). 源码下载到本地

　　2). 导入 idea 后的项目结构

3). 根据需求修改schema，执行ddl：tables_xxl_job.sql

4). xxlj-job 默认使用 hikari 作为连接池，如使用 druid 需要修改数据源。修改 pom.xml，添加 druid 依赖：

<!-- https://mvnrepository.com/artifact/com.alibaba/druid -->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid</artifactId>
    <version>1.1.18</version>
</dependency>

5). 启动 xxl-job-admin, xxl-job-executor-sample-springboot

xxl-job-admin 2.2.0 版本工作流程图（基本都是看源码归纳，因为视屏中的版本和本版本 2.2.0不一样）：

xxl-job-executor-sample-springboot 2.2.0 版本工作流程图

从 admin 后台主动触发执行作业入口前端 js

admin 触发执行作业后台入口

xxl-job-executor-sample-springboot 收到执行作业通知，执行作业入口

自动注册 handler 客户端

自动注册 admin 服务端

admin 后台页面和数据结构

1. 后台页面

1.1. 运行报表页。对应表：xxl_job_log_report

1.2. 任务管理页。对应表：xxl_job_info

1.3. 调度日志页，用于查询任务的执行情况。对应表：xxl_job_log

1.4. 执行器管理页。对应表：xxl_job_group

1.5. 用户管理页。对应表：xxl_job_user

INSERT INTO `xxl_job_lock` ( `lock_name`) VALUES ( 'schedule_lock');

问题一，executor 另起一个 nio server 有什么用？

用于接收 job 相关请求, 使 job 与原应用 Controller 层解耦

问题二， Method has too many Body parameters

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.isoftstone.pcis.module.ebpolicylanding.service.EBPolicyLandingService': FactoryBean threw exception on object creation; 
nested exception is java.lang.IllegalStateException: Method has too many Body parameters: public abstract com.isoftstone.pcis.nvhl.service.domain.GeneratingPoilcyResponseDTO com.isoftstone.pcis.module.ebpolicylanding.service.EBPolicyLandingService.saveEBPolicy(com.isoftstone.pcis.nvhl.service.domain.EBPolicyDTO,org.springframework.validation.BindingResult)

问题三，日志输出 sql：

org.apache.ibatis.executor.SimpleExecutor

问题四，停止注册
