springboot项目整合-分布式任务调度平台-XXL-JOB

分布式任务调度平台-XXL-JOB

官网地址：https://www.xuxueli.com/index.html

1.下载源代码：https://github.com/xuxueli/xxl-job

其中admin是xxl-job的调度中心

2.初始化sql

“调度数据库初始化SQL脚本” 位置为:

/xxl-job/doc/db/tables_xxl_job.sql

3.修改配置文件，连到自己的mysql，运行

访问地址：http://localhost:8080/xxl-job-admin

可以再里面配置定时任务

4.搭建一个springboot项目

1.引入maven的依赖

<!-- http://repo1.maven.org/maven2/com/xuxueli/xxl-job-core/ -->
<dependency>
    <groupId>com.xuxueli</groupId>
    <artifactId>xxl-job-core</artifactId>
    <version>${最新稳定版本}</version>
</dependency>

2.配置application.properties

### 调度中心JDBC链接：链接地址请保持和 2.1章节 所创建的调度数据库的地址一致
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=root
spring.datasource.password=root_pwd
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
### 报警邮箱
spring.mail.host=smtp.qq.com
spring.mail.port=25
[email protected]
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
### 调度中心通讯TOKEN [选填]：非空时启用；
xxl.job.accessToken=
### 调度中心国际化配置 [必填]： 默认为 "zh_CN"/中文简体, 可选范围为 "zh_CN"/中文简体, "zh_TC"/中文繁体 and "en"/英文；
xxl.job.i18n=zh_CN
## 调度线程池最大线程配置【必填】
xxl.job.triggerpool.fast.max=200
xxl.job.triggerpool.slow.max=100
### 调度中心日志表数据保存天数 [必填]：过期日志自动清理；限制大于等于7时生效，否则, 如-1，关闭自动清理功能；
xxl.job.logretentiondays=30

3.添加XxlJobConfig

package com.jtlsp.config;

import com.xxl.job.core.executor.impl.XxlJobSpringExecutor;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * @Auther: a
 * @Date: 2020/5/29 15:34
 * @Description:
 */
@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(">>>>>>>>>>> xxl-job config init.");
        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;
    }
}

4.添加测试方法 DemoJobHandler

package com.jtlsp.common;

import com.xxl.job.core.biz.model.ReturnT;
import com.xxl.job.core.handler.IJobHandler;
import com.xxl.job.core.handler.annotation.XxlJob;
import com.xxl.job.core.log.XxlJobLogger;
import org.springframework.stereotype.Component;

import java.util.concurrent.TimeUnit;

/**
 * @Auther: yanziyu
 * @Date: 2020/5/29 15:39
 * @Description:
 */
@Component
public class DemoJobHandler extends IJobHandler {

    @Override
    @XxlJob("demoJobHandler")
    public ReturnT<String> execute(String param) throws Exception {
        XxlJobLogger.log("XXL-JOB, Hello World.");

        for (int i = 0; i < 5; i++) {
            XxlJobLogger.log("beat at:" + i);
            TimeUnit.SECONDS.sleep(2);
        }
        return SUCCESS;
    }

}

5.调度中心配置启动

总结

其实配置还是非常简单的只需要下载源码 ，代码里面有各种示例代码
整合了springboot，spring等相关项目可以参考
