获取Bean的工具类

package com.jy.chat_status_server.common.utils;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

@Component
public class ApplicationHelper implements ApplicationContextAware {
    private  static ApplicationContext applicationContext;

    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        ApplicationHelper.applicationContext= applicationContext;
    }
    public  static Object getBean(String name){
        System.out.println(applicationContext);
        return applicationContext.getBean(name);
    }
