springboot集成xxl-job详解

1、springboot集成xxl-job：

（1）pom文件里引入xxl-job依赖

<!-- xxl-job-core -->
<dependency><groupId>com.xuxueli</groupId><artifactId>xxl-job-core</artifactId><version>2.4.0</version>
</dependency>

（2）application.properties配置文件：

# xxl-job
xxl.job.admin.addresses=http://127.0.0.1:8080/xxl-job-admin### xxl-job, access token
xxl.job.accessToken=default_token### xxl-job executor appname
xxl.job.executor.appname=xj-store
### 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=/data/applogs/xxl-job/jobhandler
### xxl-job executor log-retention-days
xxl.job.executor.logretentiondays=30

（3）在你的项目里新建文件结构如下：

|
|______BizApplication.java		# 启动类
|______biz
|_______|____controller
|_______|____job
|_______|______|____config
|_______|______|________|____XxlJobConfig.java
|_______|______|____handle
|_______|______|________|____DevUserHandler.java

XxlJobConfig.java文件内容如下：

package com.unicom.mark.job.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*/

DevUserHandler.java文件内容如下：

package com.unicom.mark.job.handler;import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import com.unicom.framework.utils.StringUtils;
import com.unicom.mark.dao.mapper.CertificationUserMapper;

@Component
