SpringCloud - 任务调度 - xxl-job-java

1 搭建java执行环境

创建springboot项目，并添加maven

XML 复制代码

        <dependency>
            <groupId>com.xuxueli</groupId>
            <artifactId>xxl-job-core</artifactId>
            <version>3.4.0</version>
        </dependency>

2 配置环境

2.1 配置参数

XML 复制代码

xxl:
  job:
    admin:
      addresses: http://ip:port/xxl-job-admin
    accessToken: default_token
    executor:
      appName: report-executor
      ip: 
      port: 9999
      address:
      logpath: D:/jobhandler
      logretentiondays: 30

2.2 JAVA连接服务

XML 复制代码

@Slf4j
@Configuration
public class ReportTaskConfig {
    @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() {
        log.info(">>>>>>>>>>> xxl-job config init.");
        XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
        xxlJobSpringExecutor.setAdminAddresses(adminAddresses);
        xxlJobSpringExecutor.setAppname(appname);
        xxlJobSpringExecutor.setIp(ip);
        xxlJobSpringExecutor.setPort(port);
        xxlJobSpringExecutor.setAccessToken(accessToken);
        xxlJobSpringExecutor.setLogPath(logPath);
        xxlJobSpringExecutor.setLogRetentionDays(logRetentionDays);
        return xxlJobSpringExecutor;
    }
}

3 执行逻辑

3.1 创建任务句柄

复制代码

@Slf4j
public class DemoTaskHandler extends IJobHandler {
    @Override
    public void execute() throws Exception {
        String param = XxlJobHelper.getJobParam();
        log.info("执行信息,{}",param);
        XxlJobHelper.handleFail("执行异常");
    }
}

3.2 注册任务

复制代码

XxlJobSpringExecutor.registryJobHandler("demoJobHandler1",new DemoTaskHandler());

3.3 在管理页面执行创建任务

3.4 执行一次进行测试

在控制台输出：

复制代码

执行信息,{"test": 1}
