**Spring Boot 使用 XXL-Job 实现分布式任务调度** XXL-Job 是一款轻量级分布式任务调度平台，由两部分组成：调度中心（xxl-job-admin）和执行器（xxl-job-executor）。在 Spring Boot 应用中集成 XXL-Job 可以方便地实现分布式任务调度，提升系统的可扩展性和容错性。本文将详细介绍如何在 Spring Boot 项目中配置和使用 XXL-Job。 ### 1. 配置 XXL-Job 你需要在你的项目中引入 XXL-Job 的依赖。在 `pom.xml` 文件中添加如下依赖： ```xml <dependency> <groupId>com.xxl.job</groupId> <artifactId>xxl-job-core</artifactId> <version>最新版本号</version> </dependency> ``` 接着，配置 XXL-Job 的相关属性。在 `application.properties` 或 `application.yml` 文件中添加如下配置： ```properties # 配置 XXL-JOB 调度中心地址 xxl.job.admin.addresses=http://调度中心IP:端口号 # 配置 XXL-JOB 执行器AppName，对应xxl-job-admin中的执行器注册分组 xxl.job.executor.appname=yourExecutorAppName # 配置 XXL-JOB 执行器注册地址，通常是 Spring Boot 的服务器地址 xxl.job.executor.ip=你的服务器IP xxl.job.executor.port=你的服务器端口号 # 配置 XXL-JOB 调度器日志路径 xxl.job.executor.logpath=/path/to/xxl-job/log xxl.job.executor.logretentiondays=30 # 日志保留天数 ``` ### 2. 创建 Job Handler XXL-Job 通过 Job Handler 来执行具体的任务。你需要创建一个实现了 `com.xxl.job.core.handler.IJobHandler` 接口的类，并在其中编写你的业务逻辑。例如： ```java package com.example.jobhandler; import com.xxl.job.core.biz.model.ReturnT; import com.xxl.job.core.handler.annotation.XxlJob; import org.springframework.stereotype.Component; @Component public class MyJobHandler implements IJobHandler { @Override public String getHandler() { return "myJobHandler"; } @XxlJob("myJobHandler") public ReturnT<String> execute(String param) { // 你的任务执行逻辑 System.out.println("MyJobHandler 正在执行..."); return ReturnT.SUCCESS; } } ``` 这里 `@XxlJob("myJobHandler")` 注解用于标记该方法为可被调度的任务。 ### 3. 注册执行器到 XXL-Job 启动你的 Spring Boot 服务后，XXL-Job 执行器会自动注册到调度中心。你可以在 `xxl-job-admin` 的执行器管理页面看到你的执行器已经注册成功。 ### 4. 创建定时任务在 `xxl-job-admin` 的任务调度页面，可以创建新的定时任务。选择执行器、填入 Job Handler 名称（与你定义的 `getHandler()` 方法返回值一致），并设置执行周期等参数。还可以通过 OpenFeign 调用接口来动态添加或修改定时任务，这需要在你的 Spring Boot 项目中配置 OpenFeign 并编写相关接口。 ```java package com.example.feign; import com.xxl.job.core.biz.model.AddJobParam; import com.xxl.job.core.biz.model.JobInfo; import org.springframework.cloud.openfeign.FeignClient; import org.springframework.web.bind.annotation.*; @FeignClient(name = "xxl-job-admin", fallbackFactory = JobAdminFallbackFactory.class) public interface JobAdminClient { @PostMapping("/api/job/add") JobInfo addJob(@RequestBody AddJobParam addJobParam); // 其他接口... } ``` ### 5. 监控与调试在任务执行过程中，XXL-Job 提供了丰富的日志监控功能，可以查看任务的执行状态、日志输出等信息。此外，还可以通过 `@XxlJob` 注解的 `logId` 参数进行任务调试。通过以上步骤，你已经在 Spring Boot 应用中成功集成了 XXL-Job，实现了分布式任务调度。利用 XXL-Job，你可以灵活地管理和调度你的定时任务，提高系统的可靠性和灵活性。同时，结合 Nacos 和 OpenFeign，可以进一步实现动态任务管理和微服务之间的通信。

For example, "*" * in the minute field means "every minute". * * The '?' character is allowed for the day-of-month and day-of-week fields. It * is used to specify 'no specific value'. This is useful when you need to * specify something in one of the two fields, but not the other. * * The '-' character is used to specify ranges For example "10-12" in * the hour field means "the hours 10, 11 and 12". * * The ',' character is used to specify additional values. For example * "MON,WED,FRI" in the day-of-week field means "the days Monday, * Wednesday, and Friday". * * The '/' character is used to specify increments. For example "0/15" * in the seconds field means "the seconds 0, 15, 30, and 45". And * "5/15" in the seconds field means "the seconds 5, 20, 35, and * 50". Specifying '*' before the '/' is equivalent to specifying 0 is * the value to start with. Essentially, for each field in the expression, there * is a set of numbers that can be turned on or off. For seconds and minutes, * the numbers range from 0 to 59. For hours 0 to 23, for days of the month 0 to * 31, and for months 0 to 11 (JAN to DEC). The "/" character simply helps you turn * on every "nth" value in the given set. Thus "7/6" in the * month field only turns on month "7", it does NOT mean every 6th * month, please note that subtlety. * * The 'L' character is allowed for the day-of-month and day-of-week fields. * This character is short-hand for "last", but it has different * meaning in each of the two fields. For example, the value "L" in * the day-of-month field means "the last day of the month" - day 31 * for January, day 28 for February on non-leap years. If used in the * day-of-week field by itself, it simply means "7" or * "SAT". But if used in the day-of-week field after another value, it * means "the last xxx day of the month" - for example "6L" * means "the last friday of the month". You can also specify an offset * from the last day of the month, such as "L-3" which would mean the third-to-last * day of the calendar month. When using the 'L' option, it is important not to * specify lists, or ranges of values, as you'll get confusing/unexpected results. * * The 'W' character is allowed for the day-of-month field. This character * is used to specify the weekday (Monday-Friday) nearest the given day. As an * example, if you were to specify "15W" as the value for the * day-of-month field, the meaning is: "the nearest weekday to the 15th of * the month". So if the 15th is a Saturday, the trigger will fire on * Friday the 14th. If the 15th is a Sunday, the trigger will fire on Monday the * 16th. If the 15th is a Tuesday, then it will fire on Tuesday the 15th. * However if you specify "1W" as the value for day-of-month, and the * 1st is a Saturday, the trigger will fire on Monday the 3rd, as it will not * 'jump' over the boundary of a month's days. The 'W' character can only be * specified when the day-of-month is a single day, not a range or list of days. * * The 'L' and 'W' characters can also be combined for the day-of-month * expression to yield 'LW', which translates to "last weekday of the * month". * * The '#' character is allowed for the day-of-week field. This character is * used to specify "the nth" XXX day of the month. For example, the * value of "6#3" in the day-of-week field means the third Friday of * the month (day 6 = Friday and "#3" = the 3rd one in the month). * Other examples: "2#1" = the first Monday of the month and * "4#5" = the fifth Wednesday of the month. Note that if you specify * "#5" and there is not 5 of the given day-of-week in the month, then * no firing will occur that month. If the '#' character is used, there can * only be one expression in the day-of-week field ("3#1,6#3" is * not valid, since there are two expressions). * * <!--The 'C' character is allowed for the day-of-month and day-of-week fields. * This character is short-hand for "calendar". This means values are * calculated against the associated calendar, if any. If no calendar is * associated, then it is equivalent to having an all-inclusive calendar. A * value of "5C" in the day-of-month field means "the first day included by the
