xxl-job（客户端）

引入依赖

<dependency>
    <groupId>com.xuxueli</groupId>
    <artifactId>xxl-job-core</artifactId>
    <version>2.4.0</version>
</dependency>

改配置

server.port=9992

# 调度中心的地址
xxl.job.admin.addresses=http://localhost:8080/xxl-job-admin
xxl.job.accessToken=default_token

# 执行器的名称
xxl.job.executor.appname=xxl-ccb

# 执行器地址，如果没有配置，就使用 IP:PORT 作为默认值
xxl.job.executor.address=
xxl.job.executor.ip=
xxl.job.executor.port=${random.int[9000,10000]}

# 执行器日志文件存放地址
xxl.job.executor.logpath=D:/xxl-job/jobhandler
# 执行器日志文件保存天数
xxl.job.executor.logretentiondays=30

配置类

@Configuration
public class XxlJobConfig {
    private Logger logger = LoggerFactory.getLogger(XxlJobConfig.class);

    @Value("${xxl.job.admin.addresses}")
    private String adminAddresses;

    @Value("${xxl.job.accessToken}")
    private String accessToken;

    @Value("${xxl.job.executor.appname}")
    private String appname;

    @Value("${xxl.job.executor.address}")
    private String address;

    @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(">>>>>>>>>>> 执行器初始化");

        XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
        xxlJobSpringExecutor.setAdminAddresses(adminAddresses);
        xxlJobSpringExecutor.setAppname(appname);
        xxlJobSpringExecutor.setAddress(address);
        xxlJobSpringExecutor.setIp(ip);
        xxlJobSpringExecutor.setPort(port);
        xxlJobSpringExecutor.setAccessToken(accessToken);
        xxlJobSpringExecutor.setLogPath(logPath);
        xxlJobSpringExecutor.setLogRetentionDays(logRetentionDays);

        return xxlJobSpringExecutor;
    }

}

创建任务

@Component
public class MyTask {

    // 参数和返回值都是固定的，不能更改
    @XxlJob("myTask")
    public ReturnT<String> myTask(String param) {
        XxlJobContext xxlJobContext = XxlJobContext.getXxlJobContext();
        
        String jobParam = xxlJobContext.getJobParam();
        XxlJobHelper.log("hello world: {}", jobParam);

        return ReturnT.SUCCESS;
    }
}
