>         <artifactId>xxl-job-core</artifactId>
>         <version>2.2.0</version>
>     </dependency>

2.引入配置文件

>     @Slf4j
>     @Configuration
>     @EnableConfigurationProperties(XxlJobProps.class)
>     public class XxlJobConfig {
>     
>         @Autowired
>         private XxlJobProps conf;
>     
>         @Bean
>         public XxlJobSpringExecutor xxlJobExecutor() {
>             log.info(">>>>>>>>>>> xxl-job config init.");
>             XxlJobSpringExecutor xxlJobSpringExecutor = new XxlJobSpringExecutor();
>             xxlJobSpringExecutor.setAdminAddresses(conf.getAdmin().getAddresses());
>             xxlJobSpringExecutor.setAppname(conf.getExecutor().getAppName());
>             xxlJobSpringExecutor.setIp(conf.getExecutor().getIp());
>             xxlJobSpringExecutor.setPort(conf.getExecutor().getPort());
>             xxlJobSpringExecutor.setAccessToken(conf.getAccessToken());
>             xxlJobSpringExecutor.setLogPath(conf.getExecutor().getLogPath());
>             xxlJobSpringExecutor.setLogRetentionDays(conf.getExecutor().getLogRetentionDays());
>             return xxlJobSpringExecutor;
>         }
>     }

XxlJobProps 属性

xxl -job 地址配置

> xxl:  
>   job:  
>     admin:
