XXL-JOB--使用/教程/实例

快来打我* 2023-01-08 07:27 120阅读 0赞

# 简介 #

**说明**

官网上的教程已经超级详细了。本处写一个实例来验证。

**官网**

[分布式任务调度平台XXL-JOB][XXL-JOB]

# 实例 #

需求：微服务启动2个实例，这两个实例以负载均衡的方式运行同一个定时任务。

本实例所有源码：[demo\_JAVA: Demo - Gitee.com][demo_JAVA_ Demo - Gitee.com]

## 建库建表 ##

下载项目源码并解压，获取 “调度数据库初始化SQL脚本” 并执行即可。

浏览地址：[xxl-job: 一个分布式任务调度平台，其核心设计目标是开发迅速、学习简单、轻量级、易扩展。现已开放源代码并接入多家公司线上产品线，开箱即用。 - Gitee.com][xxl-job_ _ - Gitee.com]

下载地址：[xxl-job 发行版 - Gitee.com][xxl-job _ - Gitee.com]

## 部署“调度中心” ##

**打开项目**

把上边下载的项目源码并解压，按照maven格式将源码导入IDE, 使用maven进行编译即可。源码结构如下：

xxl-job-admin：调度中心
    xxl-job-core：公共依赖
    xxl-job-executor-samples：执行器Sample示例（选择合适的版本执行器，可直接使用，也可以参考其并将现有项目改造成执行器）
        ：xxl-job-executor-sample-springboot：Springboot版本，通过Springboot管理执行器，推荐这种方式；
        ：xxl-job-executor-sample-spring：Spring版本，通过Spring容器管理执行器，比较通用；
        ：xxl-job-executor-sample-frameless：无框架版本；

**修改配置文件**

/xxl-job/xxl-job-admin/src/main/resources/application.properties //改动部分已经加粗

     * 2、为Job方法添加注解 "@XxlJob(value="自定义jobhandler名称", init = "JobHandler初始化方法", destroy = "JobHandler销毁方法")"，注解value值对应的是调度中心新建任务的JobHandler属性的值。
     * 3、执行日志：需要通过 "XxlJobLogger.log" 打印执行日志；

## 测试 ##

**部署调度中心**

> Idea运行“调度中心（xxl-job-admin）”即可。

> **查看结果**
> 
> 访问地址：[http://localhost:8080/xxl-job-admin][http_localhost_8080_xxl-job-admin] (该地址执行器将会使用到，作为回调地址)
> 
> 默认登录账号 “admin/123456”, 登录后运行界面如下图所示。

**添加执行器**

> **注意**
> 
>  *  AppName要对应application.yml里边的 xxl.job.executor.appname项。
>  *  自动注册时，机器地址无法输入，它是自动获取的。
