A:然后把xxl-job下的xxl-job-admin 导入到Eclipse中进行打包。【因为xxl-job分为服务端和客户端两个。xxl-job-admin为服务端和管理界面】
B.把xxl-jobdocdb下的tables_xxl_job.sql导入到mysql数据库
tables_xxl_job.sql内容如下:

C.修改xxl-job-admin的配置文件【主要修改数据库相关信息】
### web
server.port=8080
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.templateLoaderPath=classpath:/templates/
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
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
### datasource-pool
spring.datasource.type=com.zaxxer.hikari.HikariDataSource
spring.datasource.hikari.minimum-idle=10
spring.datasource.hikari.maximum-pool-size=30
spring.datasource.hikari.auto-commit=true
spring.datasource.hikari.idle-timeout=30000
spring.datasource.hikari.pool-name=HikariCP
spring.datasource.hikari.max-lifetime=900000
spring.datasource.hikari.connection-timeout=10000
spring.datasource.hikari.connection-test-query=SELECT 1
spring.datasource.hikari.validation-timeout=1000
### xxl-job, email
spring.mail.host=smtp.qq.com
spring.mail.port=25
spring.mail.username=xxxx@qq.com
spring.mail.from=xxxx@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=

xxl.job.i18n=zh_CN
## xxl-job, triggerpool max size
xxl.job.triggerpool.fast.max=200
xxl.job.triggerpool.slow.max=100
### xxl-job, log retention days
xxl.job.logretentiondays=30
D.打包成xxl-job-admin-2.3.0.jar文件,然后启动信息,启动结果如图
E.开始集成Springboot【重新初始化一套Springboot代码】
springboot中的pom.xml主要是集成如下两个包
第一个
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>2.3.7.RELEASE</version>
</dependency>
第二个
<!-- http://repo1.maven.org/maven2/com/xuxueli/xxl-job-core/ -->
<dependency>
<groupId>com.xuxueli</groupId>
<artifactId>xxl-job-core</artifactId>
<version>2.3.0</version>
</dependency>
F.开始编写对应代码
Springboot启动类
package cn.codepeople;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class CodepeopleApplication {
public static void main(String[] args) {
SpringApplication.run(CodepeopleApplication.class, args);
}
}
配置文件
# 应用名称
spring.application.name=codepeople
# 应用服务 WEB 访问端口,不要和服务器端冲突
server.port=8082
### 调度中心部署跟地址 [选填]:如调度中心集群部署存在多个地址则用逗号分隔。执行器将会使用该地址进行"执行器心跳注册"和"任务结果回调";为空则关闭自动注册;
xxl.job.admin.addresses=http://localhost:8080/xxl-job-admin
### 执行器通讯TOKEN [选填]:非空时启用;
xxl.job.accessToken=
### 执行器AppName [选填]:执行器心跳注册分组依据;为空则关闭自动注册
xxl.job.executor.appname=xxl-job-executor-sample
### 执行器注册 [选填]:优先使用该配置作为注册地址,为空时使用内嵌服务 ”IP:PORT“ 作为注册地址。从而更灵活的支持容器类型执行器动态IP和动态映射端口问题。
xxl.job.executor.address=
### 执行器IP [选填]:默认为空表示自动获取IP,多网卡时可手动设置指定IP,该IP不会绑定Host仅作为通讯实用;地址信息用于 "执行器注册" 和 "调度中心请求并触发任务";
xxl.job.executor.ip=
### 执行器端口号 [选填]:小于等于0则自动获取;默认端口为9999,单机部署多个执行器时,注意要配置不同执行器端口;
xxl.job.executor.port=9999
### 执行器运行日志文件存储磁盘路径 [选填] :需要对该路径拥有读写权限;为空则使用默认路径;
xxl.job.executor.logpath=/data/applogs/xxl-job/jobhandler
### 执行器日志文件保存天数 [选填] : 过期日志自动清理, 限制值大于等于3时生效; 否则, 如-1, 关闭自动清理功能;
xxl.job.executor.logretentiondays=30
初始化配置信息使Springboot通过bean对配置信息进行管理
package cn.codepeople.config;
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;
import com.xxl.job.core.executor.impl.XxlJobSpringExecutor;
@Configuration
public class XxJobConfig {
private final static Logger logger = LoggerFactory.getLogger(XxJobConfig.class);
@Value("${xxl.job.admin.addresses}")
private String adminAddresses;
@Value("${xxl.job.executor.appname}")
private String appname;
@Value("${xxl.job.executor.ip}")
private String ip;
@Value("${xxl.job.executor.port}")
private int port;
@Value("${xxl.job.accessToken}")
private String accessToken;
@Value("${xxl.job.executor.logpath}")
private String logPath;
@Value("${xxl.job.executor.logretentiondays}")
private int logRetentionDays;
@Bean
public XxlJobSpringExecutor xxlJobSpringExecutor(){
logger.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;
}
}
编写个人定时任务
package cn.codepeople.xxljob;
import java.util.concurrent.TimeUnit;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import com.xxl.job.core.biz.model.ReturnT;
import com.xxl.job.core.context.XxlJobHelper;
import com.xxl.job.core.handler.IJobHandler;
import com.xxl.job.core.handler.annotation.XxlJob;
import groovy.util.logging.Slf4j;
@Component
@Slf4j
public class MyDemoJobHandler extends IJobHandler{
private static final Logger logger = LoggerFactory.getLogger(MyDemoJobHandler.class);
@Override
public void execute() throws Exception {
logger.info("xxl-job, heoooo world.");
}
@XxlJob("demoJobHandler")
public ReturnT<String> demoJobHandler() throws Exception {
XxlJobHelper.log("XXL-JOB, Hello World.");
for (int i = 0; i < 5; i++) {
logger.info("this is >>>>>>>>>>> " + i);
TimeUnit.SECONDS.sleep(2);
}
return ReturnT.SUCCESS;
}
}
然后启动Springboot项目
F.使用浏览器访问http://localhost:8080/xxl-job-admin/地址然后登录admin/123456登录后如下界面
点击左侧菜单"任务管理"然后点击 右侧 “新增”
根据图里进行信息配置
新增任务完毕后,需要手动启动任务
然后等待一会,观察Eclipse控制台上打印的信息如下:
项目顺利成功进行
G.如果项目有问题Eclipse控制台没有打印相关的日志信息可以通过如下方法查找问题
主要的坑是在
@Bean
public XxlJobSpringExecutor xxlJobSpringExecutor(){
logger.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;
}
早期版本要加上(initMethod = "start", destroyMethod = "destroy")
如下。只要加了这一段就会一直启动报错;报错内容是端口被占用
@Bean(initMethod = "start", destroyMethod = "destroy")
public XxlJobSpringExecutor xxlJobSpringExecutor(){
logger.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;
}

注意:
最新版本目前也没有这个@JobHandler(value="demoJobHandler")
这个注解了。换成直接在方法上的注解了@XxlJob("demoJobHandler")
以上是springboot集成分布式任务调度平台XXL-JOB的最新实践
