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。
注：Spring工厂要有这个bean。
使用如下方式可以解决：
- 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.domain.OpeLog;
- import cn.ffcs.drive.service.IOpeLogService;
- import cn.ffcs.zq.util.DateUtils;
-
- @Component
- public class OpeLogUtils {
-
- private static Logger logger = LoggerFactory.getLogger(OpeLogUtils.class);
-
- @Autowired
- private IOpeLogService opeLogService;
- private static OpeLogUtils opeLogUtils;
-
- public void setUserInfo(IOpeLogService opeLogService) {
- this.opeLogService = opeLogService;
- }
-
- @PostConstruct
- public void init() {
- opeLogUtils = this;
- opeLogUtils.opeLogService = this.opeLogService;
-
- }
-
-
- public static void insertOpeLog(HttpServletRequest req, String opeDesc) {
- try {
-
- Admin admin = DriveUtil.getSessionUser(req);
-
- if(admin != null && opeDesc != null && !opeDesc.trim().equals("")){
-
-
- logger.info("开始封装日志信息。");
- OpeLog opeLog = new OpeLog();
-
- opeLog.setAdminId(admin.getId());
- opeLog.setCityCode(admin.getCityCode());
- opeLog.setOpeDesc("管理员id="+admin.getId()+"操作【"+opeDesc+"】");
- opeLog.setOpeTime(DateUtils.getNow());
- opeLog.setIsDelete("0");
- opeLogUtils.opeLogService.save(opeLog);
-
- logger.info("保存管理员操作日志成功，信息为【adminId:{},cityCode:{},opeDesc:{},opeTime:{}】",new Object[]{admin!=null?admin.getId():null,admin.getCityCode(),opeDesc,DateUtils.getNow()});
- }else{
- logger.info("保存操作日志失败，参数不足【adminId:{},cityCode:{},opeDesc:{},opeTime:{}】",new Object[]{admin!=null?admin.getId():null, admin!=null?admin.getCityCode():null, opeDesc, DateUtils.getNow()});
- }
- } catch (Exception e) {
- logger.error("保存操作日志异常，异常信息为:" + e.getMessage(), e);
- }
- }
- }
静态工具类中使用注解注入service
