一般需要在一个工具类中使用@Autowired 注解注入一个service。但是由于工具类方法一般都写成static，所以直接注入就存在问题。
使用如下方式可以解决：
代码语言：javascript复制/**
*
*/
package cn.ffcs.drive.common.util;
import javax.annotation.PostConstruct;
import javax.servlet.http.HttpServletRequest;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import cn.ffcs.drive.domain.Admin;

import cn.ffcs.drive.service.IOpeLogService;
