springboot:2.7.2
xxl-job-core: 2.3.0
一、集成xxl-job
1. 在gitee上下载xxl-job项目
git clone https://gitee.com/xuxueli0323/xxl-job.git
2. 执行以下目录下的sql
/xxl-job-2.3.0/doc/db/tables_xxl_job.sql
3. 在xxl-job-admin的项目中配置数据库信息
### xxl-job, datasource
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/xxl_job?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&serverTimezone=Asia/Shanghai
spring.datasource.username=root
spring.datasource.password=root_psw
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
4. 在xxl-job-2.3.0项目中执行 mvn clean install, 下载依赖
若报错gpg相关依赖插件没有，我目前是将pom中涉及gpg的部分暂时注释掉了
<!-- GPG -->
<!-- <plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-gpg-plugin</artifactId>
<version>${maven-gpg-plugin.version}</version>
<configuration>
<useAgent>false</useAgent>
</configuration>
<executions>
<execution>
<phase>verify</phase>
<goals>
<goal>sign</goal>
</goals>
</execution>
</executions>
</plugin> -->
5. 执行以下命令，启动xxl-job-admin
cd E:\workspace\prac\xxl-job-2.3.0\xxl-job-admin\target
java -jar xxl-job-admin-2.3.0.jar
6. 登录xxl-job-admin，账密：admin/123456
7. 项目中引入依赖
<!--xxl-job-core-->
<dependency><groupId>com.xuxueli</groupId><artifactId>xxl-job-core</artifactId><version>${xxl-job-version}</version>
</dependency>
8. application.yml配置
xxl:job:admin:addresses: http://127.0.0.1:8080/xxl-job-adminexecutor:appname: xxl-job-executor # 执行器名称，需唯一ip: 127.0.0.1 # 执行器IP（可选）port: 9999 # 执行器端口（可选）logpath: logs/xxl-job # 日志路径logretentiondays: 30 # 日志保留天数
9. 配置类XxlJobConfig
package com.yifeng.prac.config.xxljob;import com.xxl.job.core.executor.impl.XxlJobSpringExecutor;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;

二、执行器（Executor）配置
执行器是任务的实际执行节点，需要先在控制台注册。
1. 点击左侧菜单 “执行器管理”
2. 添加执行器
- 点击 新增 按钮，填写以下信息：
| 字段 | 说明 |
|---|---|
| AppName | 执行器名称（需唯一，与执行器配置文件中 xxl.job.executor.appname 一致） |
| 名称 | 执行器显示名称（可自定义） |
| 注册方式 | 选择 自动注册（执行器启动后自动注册） |
| 调度中心地址 | 调度中心地址（默认 http://127.0.0.1:8080/xxl-job-admin） |
注意：确保执行器配置文件中的 xxl.job.executor.appname 与控制台配置的 AppName 一致。
三、任务配置
任务是调度中心的核心管理单元，用于定义调度逻辑、执行策略等。
1. 进入 任务管理 页面
- 点击左侧菜单 “任务管理” 。
2. 添加任务
- 点击 新增 按钮，填写以下信息：
四、调度配置详解
1. 调度时间（Cron 表达式）
- 使用标准的 Cron 表达式定义任务调度频率。
- 示例：
0 0/1 * * * ?：每分钟执行一次0 0 0 * * ?：每天凌晨执行0 0 12 * * MON-FRI：每周一至周五中午12点执行
- 推荐工具：Cron 表达式生成器
五、任务日志查看
1. 查看任务执行日志
- 在 任务管理 页面点击 日志 按钮，查看任务执行详情。
2. 日志文件位置
默认日志路径为 logs/xxl-job，可在执行器配置中修改：
xxl:job:executor:logpath: logs/xxl-job # 日志路径
六、安全与高级配置（可选）
1. Token 验证
- 在调度中心和执行器中配置相同的 token，增强安全性。
调度中心配置：
xxl.job.accessToken=your_token
执行器配置：
xxl:
job:
accessToken: your_token
