在springboot主程序里改成

public static void main(String[] args) {//        SpringApplication.run(SpringbootAPP.class, args);换成下面    SpringApplication sa = new SpringApplication(SpringbootAPP.class);    sa.addListeners(new MainBusiListeners());    sa.run(args);}

 

package com.xxx.xxxx;import com.xxx.utils.SpringContextUtils;import org.springframework.context.ApplicationListener;import org.springframework.context.event.ContextRefreshedEvent;/** * 启动监听 */public class MainBusiListeners implements ApplicationListener
     
       {    @Override    public void onApplicationEvent(ContextRefreshedEvent event) {        SpringContextUtils.setApplicationContextByMain(event.getApplicationContext());    }}
     

 

@Componentpublic class SpringContextUtils {    private static ApplicationContext applicationContext;    public static void setApplicationContextByMain(ApplicationContext applicationContext) {        if (SpringContextUtils.applicationContext == null) {            SpringContextUtils.applicationContext = applicationContext;        }    }
