集成xxl-job分布式任务调度平台

首先声明，本篇博文基于springboot，基于spring的请自行研究。

（一）启动控制平台

首先将xxl-job-master.zip下载下来，然后在mysql数据库创建xxl-job数据库。

执行数据库：

用tomcat启动xxl-job-admin以后，打开页面：http://localhost:8081/xxl-job-admin/（用户名：admin 密码：123456）

然后在页面上创建执行器和任务。

（二）创建执行器

第一步：创建maven项目

第二步：修改pom.xml文件，加入如下：

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.6.RELEASE</version>
    </parent>
    <dependencies>
        <!-- jetty -->
        <dependency>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-server</artifactId>
        </dependency>
        <dependency>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-util</artifactId>
        </dependency>
        <dependency>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-http</artifactId>
        </dependency>
        <dependency>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-io</artifactId>
        </dependency>
        <!-- spring-boot-starter-web (spring-webmvc + tomcat) -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <!-- xxl-job-core -->
        <dependency>
            <groupId>com.xuxueli</groupId>
            <artifactId>xxl-job-core</artifactId>
            <version>1.9.0-SNAPSHOT</version>
        </dependency>
    </dependencies>
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin </artifactId>
            </plugin>
        </plugins>
    </build>

第三步：在resources目录下添加application.properties和logback.xml

# web port
server.port=8084

# log config
logging.config=classpath:logback.xml

# xxl-job
### xxl-job admin address list, such as "http://address" or "http://address01,http://address02"
xxl.job.admin.addresses=http://127.0.0.1:8081/xxl-job-admin

### xxl-job executor address
xxl.job.executor.appname=ececutor01
xxl.job.executor.ip=10.1.1.23
xxl.job.executor.port=9999

### xxl-job log path
xxl.job.executor.logpath=/data/applogs/xxl-job/jobhandler/

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

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false" scan="true" scanPeriod="1 seconds">

    <contextName>logback</contextName>
    <property name="log.path" value="/data/applogs/xxl-job/xxl-job-executor-sample-springboot.log"/>

    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
       <!-- <filter class="ch.qos.logback.classic.filter.ThresholdFilter" >
            <level>WARN</level>
        </filter>-->
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} %contextName [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>

    <appender name="file" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${log.path}</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${log.path}.%d{yyyy-MM-dd}.zip</fileNamePattern>
        </rollingPolicy>
        <encoder>
            <pattern>%date %level [%thread] %logger{36} [%file : %line] %msg%n
            </pattern>
        </encoder>
    </appender>

    <root level="info">
        <appender-ref ref="console"/>
        <appender-ref ref="file"/>
    </root>

    <!--<logger name="com.xxl.job.executor.service.info" level="WARN" additivity="false">
        <appender-ref ref="console"/>
        <appender-ref ref="file"/>
    </logger>-->

</configuration>

接着，按照如下创建包和类：

XxlJobConfig：

package com.jump.config;

import com.xxl.job.core.executor.XxlJobExecutor;
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.ComponentScan;
import org.springframework.context.annotation.Configuration;

/**
 *
 */
@Configuration
@ComponentScan(basePackages = "com.xxl.job.executor.service.jobhandler")
public class XxlJobConfig {
    private Logger logger = LoggerFactory.getLogger(XxlJobConfig.class);

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

    @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.accessToken}")
    private String accessToken;

    @Bean(initMethod = "start", destroyMethod = "destroy")
    public XxlJobExecutor xxlJobExecutor() {
        logger.info(">>>>>>>>>>> xxl-job config init.");
        XxlJobExecutor xxlJobExecutor = new XxlJobExecutor();
        xxlJobExecutor.setIp(ip);
        xxlJobExecutor.setPort(port);
        xxlJobExecutor.setAppName(appname);
        xxlJobExecutor.setAdminAddresses(addresses);
        xxlJobExecutor.setLogPath(logpath);
        xxlJobExecutor.setAccessToken(accessToken);
        return xxlJobExecutor;
    }

}

MyJobHandler：

package com.jump.handler;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;

import com.xxl.job.core.biz.model.ReturnT;
import com.xxl.job.core.handler.IJobHandler;
import com.xxl.job.core.handler.annotation.JobHander;
import com.xxl.job.core.log.XxlJobLogger;

/**
 * @author Jump
 * @version 创建时间：2019年1月22日 下午1:25:13 类说明
 */
@JobHander(value = "myJobHandler")
@Service
public class MyJobHandler extends IJobHandler {
    @Value("${xxl.job.executor.port}")
    private String port;

    @Override
    public ReturnT<String> execute(String... params) throws Exception {
        XxlJobLogger.log("XXL-JOB, Hello World." + port);
        System.out.println("XXL-JOB, Hello World." + port);
        for (int i = 0; i < 5; i++) {
            XxlJobLogger.log("beat at:" + i);
            // TimeUnit.SECONDS.sleep(2);
        }
        return ReturnT.SUCCESS;
    }

}

App：

package com.jump;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @author Jump
 * @version 创建时间：2019年1月22日 下午1:27:28 类说明
 */
@SpringBootApplication
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
}

然后右键run，就能开启任务执行器。
