springboot使用xxl-job

简介

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。现已开放源代码可以根据自己需要进行修改,开箱即用,非常爽;

部署xxl-job项目

首先去github上下载:https://github.com/xuxueli/xxl-job/
下载源码,然后在本地进行编译
修改配置xxl-job-admin中的application.properties

server.port=8080
server.servlet.context-path=/xxl-job-admin
### 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=xxx
spring.datasource.password=xxxxx
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
### xxl-job, email
spring.mail.host=smtp.qq.com
spring.mail.port=25
spring.mail.username=xxx@qq.com
spring.mail.password=xxx
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.starttls.required=true
spring.mail.properties.mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory

### xxl-job, access token
xxl.job.accessToken=xxxxxx  

配置很多,但是只需要修改上面这几个,最好将xxl.job.accessToken添加上进行token验证
修改完打包部署
部署完可以通过地址查看管理页面:http://127.0.0.1:8080/xxl-job-admin/

引入项目

创建网关项目pom文件中引入jar包

<dependency>
    <groupId>com.xuxueli</groupId>
    <artifactId>xxl-job-core</artifactId>
    <version>2.2.0</version>
</dependency>

在配置文件中增肌配置

xxl:
  job:
    accessToken: xxxxxx  #修改的token秘钥
    admin:
      addresses: http://10.1.11.60:8080/xxl-job-admin/   #上面部署xxl-job-admin地址
    executor:
      appname: dayunmotor-tsp-gateway-xxl-job  #本项目名称
      ip: 10.1.5.27 #这个是本项目部署地址和端口
      port: 30003   #注意这里不是本项目的端口是xxl-job执行请求的端口
      logpath: /data/applogs/xxl-job/jobhandler
      logretentiondays: 30

在项目中增加配置类

@Slf4j
@Configuration
public class XxlJobConfig {

    @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.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;
    }
}

增加定时任务

@Slf4j
@Component
public class RemoteUpgradeTask extends IJobHandler {

    @XxlJob(value = "remoteUpgradeTask")
    public ReturnT<String> execute(String s) throws Exception {
        try {
            log.info("执行任务");
            return IJobHandler.SUCCESS;
        } catch (Exception e) {
            log.error("执行任务异常", e);
            return new ReturnT<>(IJobHandler.FAIL.getCode(), "执行任务失败");
        }
    }
    //执行初始化方法
    @Override
    public void init() throws InvocationTargetException, IllegalAccessException {
        super.init();
    }
    //执行销毁方法
    @Override
    public void destroy() throws InvocationTargetException, IllegalAccessException {
        super.destroy();
    }
}

然后去xxl-job-admin中增加执行器,增加完启动项目,可以看到启动的执行器
springboot使用xxl-job_第2张图片
然后创建定时任务:注意这里的JobHandler就是代码里的 @XxlJob(value = “remoteUpgradeTask”)
springboot使用xxl-job_第3张图片
创建完启动任务,就可以执行了,这个就完成了
不过如果使用windows的时候注意关闭防火墙,不然没法注册上去
如果本地有多网络需要指定IP,而服务器只有一个网络,为了保证本地可以进行调试,可以进行兼容;
获取当前环境,根据环境进行设置IP
首先获取当前spring.profiles.active

@Configuration
public class ApplicationContextUtils implements ApplicationContextAware {

    private static ApplicationContext applicationContext = null;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        if(null == ApplicationContextUtils.applicationContext) {
            ApplicationContextUtils.applicationContext = applicationContext;
        }
    }

    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }

    public static Object getBean(String name) {
        return applicationContext.getBean(name);
    }

    public static <T> T getBean(Class<T> clazz) {
        return applicationContext.getBean(clazz);
    }

    public static String getActiveProfile() {
        return applicationContext.getEnvironment().getActiveProfiles()[0];
    }
}

然后修改xxl-job配置,修改XxlJobConfig类

    @Bean
    public XxlJobSpringExecutor xxlJobExecutor() {
        log.info(">>>>>>>>>>> xxl-job config init.");
        XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
        xxlJobSpringExecutor.setAdminAddresses(adminAddresses);
        xxlJobSpringExecutor.setAppname(appname);
        if(ApplicationContextUtils.getActiveProfile().equalsIgnoreCase("local")){
            xxlJobSpringExecutor.setIp(ip);
        }
        xxlJobSpringExecutor.setPort(port);
        xxlJobSpringExecutor.setAccessToken(accessToken);
        xxlJobSpringExecutor.setLogPath(logPath);
        xxlJobSpringExecutor.setLogRetentionDays(logRetentionDays);

        return xxlJobSpringExecutor;
    }
