1.背景

我们项目在用xxl-job的时候，只是用到了简单的定时调度http接口功能，所以，为了减少业务工程的侵入性，我决定把executor(执行器)集成到xxl-job-admin中，这样，我们只用部署一个jar包就实现了一个定时调度服务。我们只用在业务工程中写好任务，通过http对外提供服务，xxl-job使用GLUE(Java)模式去发送http请求调用业务接口即可。

2.改造步骤

2.1下载源码

仓库地址: https://gitee.com/xuxueli0323/xxl-job

2.2修改xxl-job-admin的pom

切换到2.4.0分支，复制一份xxl-job-admin后台管理项目，并用idea重新打开，把源码项目中的doc目录复制到xxl-job-admin中。
默认mysql8，如果用的mysql5.7就换成下面的mysql-connector-java，hutool依赖是用来加到执行器中执行GLUE(Java)中的代码用的。

<!-- mysql8 -->
        <dependency>
            <groupId>com.mysql</groupId>
            <artifactId>mysql-connector-j</artifactId>
            <version>${mysql-connector-j.version}</version>
        </dependency>
		<!-- mysql5.7 -->
<!--		<dependency>-->
<!--			<groupId>mysql</groupId>-->
<!--			<artifactId>mysql-connector-java</artifactId>-->
<!--			<version>5.1.49</version>-->
<!--		</dependency>-->
        <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-all</artifactId>
            <version>5.8.22</version>
        </dependency>

把Excutor的配置集成到xxl-job-admin中

#2.4.0默认mysql8，下面是需要修改的内容--start----------------------
### xxl-job, datasource
#mysql8
spring.datasource.url=jdbc:mysql://192.168.26.160:3307/xxl_job?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&serverTimezone=Asia/Shanghai
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
#mysql5.7
#spring.datasource.url=jdbc:mysql://192.168.26.160:3307/xxl_job?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
#spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.datasource.username=root
spring.datasource.password=1234
#2.4.0默认mysql8，下面是需要修改的内容--end-----------------------



#新增执行器配置
