通常须要在一个工具类中使用@Autowired 注解注入一个service。可是因为工具类方法通常都写成static,因此直接注入就存在问题。 java
使用以下方式能够解决:
spring
- /**
- *
- */
- 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
- *
- * 管理员操做日志
- *
- * @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;
-

- this.opeLogService = opeLogService;
- }
-
- @PostConstruct
- public void init() {
- opeLogUtils = this;
- opeLogUtils.opeLogService = this.opeLogService;
-
- }
-
- /**

- * @param adminId 管理员id
- * @param opeDesc 操做日志信息
- * @param cityCode 城市编码
- */
- public static void insertOpeLog(HttpServletRequest req, String opeDesc) {
- try {

- Admin admin = DriveUtil.getSessionUser(req);
-

- opeLog.setOpeDesc("管理员id="+admin.getId()+"操做【"+opeDesc+"】");
- opeLog.setOpeTime(DateUtils.getNow());
- opeLog.setIsDelete("0");

- } catch (Exception e) {

- }
- }
