静态工具类中使用注解注入service

转载：http://blog.csdn.net/p793049488/article/details/37819121

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;

/**
 * className:OpeLogUtils
 *
 * 管理员操作日志
 *
 * @author pengyh
 * @version 1.0.0
 * @date 2014-07-10 09:04:48

 */
@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;

    }

    /**
     * 执行操作日志入库操作
     * @param adminId   管理员id
     * @param opeDesc   操作日志信息
     * @param cityCode  城市编码
     */
    public static void insertOpeLog(HttpServletRequest req, String opeDesc) {
        try {
            /**
             * 获取管理员信息
             */
            Admin admin = DriveUtil.getSessionUser(req);

            if(admin != null && opeDesc != null && !opeDesc.trim().equals("")){

                //封装日志信息
                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);
        }
    }
}
