xxl-Job详解（整合springboot）超详细

XXL-JOB是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。

整合SpringBoot步骤：

1. 添加Maven依赖

<!-- xxl-job-core -->
<dependency>
    <groupId>com.xuxueli</groupId>
    <artifactId>xxl-job-core</artifactId>
    <version>版本号</version>
</dependency>

2. 在application.properties或application.yml中配置XXL-JOB

# xxl-job admin address
xxl.job.admin.addresses=http://localhost:8080/xxl-job-admin
# xxl-job executor appname
xxl.job.executor.appname=xxl-job-executor-sample
# xxl-job executor ip
xxl.job.executor.ip=
# xxl-job executor port
xxl.job.executor.port=9999
# xxl-job executor logpath
xxl.job.executor.logpath=/data/applogs/xxl-job/jobhandler
# xxl-job executor logretentiondays
xxl.job.executor.logretentiondays=

3. 创建配置类

@Configuration
public class XxlJobConfig {
 
    private static Logger logger = LoggerFactory.getLogger(XxlJobConfig.class);
 
    @Value("${xxl.job.admin.addresses}")
    private String adminAddresses;
 
    @Value("${xxl.job.executor.appname}")
    private String appName;
 
    @Value("${xxl.job.executor.ip}")
    private String ip;
 
    @Value("${xxl.job.executor.port}")
    private int port;
 
    @Value("${xxl.job.executor.logpath}")
    private String logPath;
 
    @Value("${xxl.job.executor.logretentiondays}")
    private int logRetentionDays;
 
    @Bean
    public XxlJobSpringExecutor xxlJobExecutor() {
        logger.info(">>>>>>>>>>> xxl-job config init.");
        XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
        xxlJobSpringExecutor.setAdminAddresses(adminAddresses);
        xxlJobSpringExecutor.setAppName(appName);
        xxlJobSpringExecutor.setIp(ip);
        xxlJobSpringExecutor.setPort(port);
        xxlJobSpringExecutor.setAccessToken(null);
        xxlJobSpringExecutor.setLogPath(logPath);
        xxlJobSpringExecutor.setLogRetentionDays(logRetentionDays);
 
        return xxlJobSpringExecutor;
    }
 
    @Bean
    public CommandLineRunner xxlJobExecutorRunner(XxlJobSpringExecutor xxlJobSpringExecutor) {
        return (args) -> xxlJobSpringExecutor.start();
    }
}

4. 创建任务处理器

@Component
public class SampleXxlJob {
 
    private static final Logger logger = LoggerFactory.getLogger(SampleXxlJob.class);
 
    @XxlJob("demoJobHandler")
    public void
