springboot普通类调用spring托管的类，使用参照注释中用例

package com.prodaas.datatools.batchplatform.utils;

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

/**
 * 使用该类创建直接与数据库交互的service对象
 * 用例：ApplicationContext applicationContext = SpringHelper.getApplicationContext();
 *      StandardInfoService service = applicationContext.getBean(StandardInfoService.class);
 *      ArrayList<String[]> detailValues =(ArrayList)service.getRulesTable(f.getStdSortId());

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {

        }
    }


    //获取applicationContext
    public static ApplicationContext getApplicationContext() {

    //通过name获取 Bean.

    public static <T> T getBean(Class<T> clazz){

    //通过name,以及Clazz返回指定的Bean
    public static <T> T getBean(String name,Class<T> clazz){
