[Java知识库]springboot 2.X 整合 xxl-job 定时任务调度

创建springboot工程

xxl-job-admin 为xxl-job控制中心
demo-job 执行器demo

集成xxl-job控制台

xxl-job官网
代码地址

下载xxl-job控制台代码与sql文件

将sql导入到我们的数据库

将xxl-job-admin导入我们的工程

修改其配置文件

改好之后 启动应用即可

访问 http://localhost:9090/xxl-job-admin 进入控制台

默认账号密码为 admin/123456 可在用户头像处修改

进入到这 控制台就启动成功了

集成xxl-job执行器配置

编写项目配置文件 application.yml

server:
  port: 8080
# xxl-job 配置
xxl:
  job:
    # 调度中心地址：如调度中心集群部署存在多个地址则用逗号分隔。
    admin-addresses: http://localhost:9090/xxl-job-admin
    # 执行器通讯TOKEN：非空时启用
    access-token:
    # 执行器配置
    executor:
      # 执行器AppName：执行器心跳注册分组依据；为空则关闭自动注册
      appname: xxl-job-executor-sample
      # 执行器端口号 执行器从9101开始往后写
      port: 9101
      # 执行器注册：默认IP:PORT
      address:
      # 执行器IP：默认自动获取IP
      ip:
      # 执行器运行日志文件存储磁盘路径
      logpath: ./logs/xxl-job
      # 执行器日志文件保存天数：大于3生效
      logretentiondays: 30

编写项目配置类 XxlJobProperties.java

/**
 * xxljob配置类
 *
 * @author Lion Li
 */
@Data
@ConfigurationProperties(prefix = "xxl.job")
public class XxlJobProperties {

    private String adminAddresses;

    private String accessToken;

    private Executor executor;

    @Data
    @NoArgsConstructor
    public static class Executor {

        private String appname;

        private String address;

        private String ip;

        private int port;

        private String logPath;

        private int logRetentionDays;
    }
}

XxlJobConfig.java

/**
 * xxl-job config
 *
 * @author Lion Li
 */
@Slf4j
@Configuration
@EnableConfigurationProperties(XxlJobProperties.class)
@AllArgsConstructor
public class XxlJobConfig {

    private final XxlJobProperties xxlJobProperties;

    @Bean
    public XxlJobSpringExecutor xxlJobExecutor() {
        log.info(">>>>>>>>>>> xxl-job config init.");
        XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
        xxlJobSpringExecutor.setAdminAddresses(xxlJobProperties.getAdminAddresses());
        xxlJobSpringExecutor.setAccessToken(xxlJobProperties.getAccessToken());
        XxlJobProperties.Executor executor = xxlJobProperties.getExecutor();
        xxlJobSpringExecutor.setAppname(executor.getAppname());
        xxlJobSpringExecutor.setAddress(executor.getAddress());
        xxlJobSpringExecutor.setIp(executor.getIp());
        xxlJobSpringExecutor.setPort(executor.getPort());
        xxlJobSpringExecutor.setLogPath(executor.getLogPath());
        xxlJobSpringExecutor.setLogRetentionDays(executor.getLogRetentionDays());
        return xxlJobSpringExecutor;
    }

}

启动应用

启动成功后 查看控制台 执行器界面

成功注册到 控制中心

编写测试方法

复制官方demo

创建 SampleService.java 将官方demo复制进来

/**
 * XxlJob开发示例（Bean模式）
 * <p>
 * 开发步骤：
 * 1、任务开发：在Spring Bean实例中，开发Job方法；
 * 2、注解配置：为Job方法添加注解 "@XxlJob(value="自定义jobhandler名称", init = "JobHandler初始化方法", destroy = "JobHandler销毁方法")"，注解value值对应的是调度中心新建任务的JobHandler属性的值。
 * 3、执行日志：需要通过 "XxlJobHelper.log" 打印执行日志；
 * 4、任务结果：默认任务结果为 "成功" 状态，不需要主动设置；如有诉求，比如设置任务结果为失败，可以通过 "XxlJobHelper.handleFail/handleSuccess" 自主设置任务结果；

官方demo涵盖了大部分的使用案例 大家一定要仔细阅读

执行测试

编写好代码后重启服务

日志输出所有扫描到的demo案例
进入控制台 任务管理 执行案例
