实战

搭建调度中心

第一步：下载XXL-JOB项目（略）。 

---

 第二步：执行相关的SQL脚本，此时会创建一个名字为xxl_job的数据库。

---

第三步：在xxl-job-admin项目中配置application.properties。需要注意基础配置，如：端口、数据库连接配置、访问地址，日志所在目录等。

### web
server.port=8099
server.servlet.context-path=/xxl-job-admin

### actuator
management.server.servlet.context-path=/actuator
management.health.mail.enabled=false

### resources
spring.mvc.servlet.load-on-startup=0
spring.mvc.static-path-pattern=/static/**
spring.resources.static-locations=classpath:/static/

### freemarker

spring.freemarker.suffix=.ftl
spring.freemarker.charset=UTF-8
spring.freemarker.request-context-attribute=request
spring.freemarker.settings.number_format=0.##########

### mybatis
mybatis.mapper-locations=classpath:/mybatis-mapper/*Mapper.xml
#mybatis.type-aliases-package=com.xxl.job.admin.core.model

### 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=root

### xxl-job, email
spring.mail.host=smtp.qq.com
spring.mail.port=25
spring.mail.username=xxx@qq.com
spring.mail.from=xxx@qq.com
spring.mail.password=xxx
spring.mail.properties.mail.smtp.auth=true

### xxl-job, i18n (default is zh_CN, and you can choose "zh_CN", "zh_TC" and "en")
xxl.job.i18n=zh_CN

## xxl-job, triggerpool max size

xxl.job.triggerpool.slow.max=100

### xxl-job, log retention days
xxl.job.logretentiondays=30

### xxl-job admin address list, such as "http://address" or "http://address01,http://address02"
xxl.job.admin.addresses=http://127.0.0.1:8099/xxl-job-admin

### xxl-job executor appname
xxl.job.executor.appname=xxl-job-executor-sample
### xxl-job executor registry-address: default use address to registry , otherwise use ip:port if address is null
xxl.job.executor.address=
### xxl-job executor server-info
xxl.job.executor.ip=
xxl.job.executor.port=9999
### xxl-job executor log-path
xxl.job.executor.logpath=D:/idea_workflow/xxl-job-master/log
### xxl-job executor log-retention-days
xxl.job.executor.logretentiondays=30

第四步：配置XxlJobSpringExecutor对象。

package com.xxl.job.admin.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;

/**
 * xxl-job config
 *
 * @author xuxueli 2017-04-28
 */
@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;
    }

    /**
     * 针对多网卡、容器内部署等情况，可借助 "spring-cloud-commons" 提供的 "InetUtils" 组件灵活定制注册IP；
     *
     *      1、引入依赖：
     *          <dependency>
     *             <groupId>org.springframework.cloud</groupId>
     *             <artifactId>spring-cloud-commons</artifactId>
     *             <version>${version}</version>
     *         </dependency>
     *
     *      2、配置文件，或者容器启动变量
     *          spring.cloud.inetutils.preferred-networks: 'xxx.xxx.xxx.'
     *
     *      3、获取IP
     *          String ip_ = inetUtils.findFirstNonLoopbackHostInfo().getIpAddress();
     */
}

第五步：启动xxl-job-admin项目，并访问后台管理系统（登录的账号/密码保存在xxl_job_user表中，初始账号/密码：admin/123456）。

#访问路径配置在application.properties文件的xxl.job.admin.addresses属性上。
http://127.0.0.1:8099/xxl-job-admin

---

创建任务调度（这里演示SpringBoot版本）

第一步：在xxl-job-executor-sample-springboot服务配置application.properties配置文件，注意和调度中心的xxl.job.admin.addresses对应起来。

# web port
server.port=8091
# no web
#spring.main.web-environment=false

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

### xxl-job admin address list, such as "http://address" or "http://address01,http://address02"
xxl.job.admin.addresses=http://127.0.0.1:8099/xxl-job-admin

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

### xxl-job executor appname
xxl.job.executor.appname=xxl-job-executor-sample
### xxl-job executor registry-address: default use address to registry , otherwise use ip:port if address is null
xxl.job.executor.address=
### xxl-job executor server-info
xxl.job.executor.ip=127.0.0.1
xxl.job.executor.port=9990
### xxl-job executor log-path
xxl.job.executor.logpath=D:/idea_workflow/xxl-job-master/log
### xxl-job executor log-retention-days
xxl.job.executor.logretentiondays=30

第二步：登录后台管理系统，将刚才的信息录入到执行器管理。

 第三步：在xxl-job-executor-sample-springboot编写调度任务并启动项目。

    @XxlJob("myJobHandler")
    public void myJobHandler() throws Exception {
        System.out.println("hello world!");
    }

---

第四步：在后台管理系统设置调度任务的配置。

第五步：启动xxl-job-executor-sample-springboot项目，尝试执行调度任务。
