springBoot中starter

springBoot项目中引入starter

项目引入xxljob，仅需要导入对应的starter包，即可进行快速开发

xxl-job-spring-boot-starter

目录结构：

pom.xml中仅导入对应的xxl-job-spring-boot-autoconfiguration依赖

spring.factories文件（spring启动的时候会加载此文件中的配置类）

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.ydl.xxljobspringbootautoconfiguration.XxlJobAutoConfiguration

另外这个spring.factories文件还可配置监听类

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.alibaba.boot.dubbo.autoconfigure.DubboAutoConfiguration
 
 
org.springframework.context.ApplicationListener=\
com.alibaba.boot.dubbo.context.event.OverrideDubboConfigApplicationListener,\
com.alibaba.boot.dubbo.context.event.WelcomeLogoApplicationListener,\
com.alibaba.boot.dubbo.context.event.AwaitingNonWebApplicationListener

public class AwaitingNonWebApplicationListener implements ApplicationListener {
 
@Order //最低优先级确保最后执行
public class OverrideDubboConfigApplicationListener implements ApplicationListener {
 
 
@Order(LoggingApplicationListener.DEFAULT_ORDER + 1)
public class WelcomeLogoApplicationListener implements ApplicationListener {
