spring配置日志切面，实现系统操作日志记录-蒲公英云

spring配置日志切面，实现系统操作日志记录

//做系统是经常会遇到的情况之一，对系统操作日志存表记录

下面给出下例子

需要注意的是，日志通常数据量会很大，建议已每个人月一张表，或者其他方式分表

例如：logs_2012_1

        logs\_2012\_2
        logs\_2012\_3

这样的形式。

需要引入的jar包

至少得有aop和切面包

1，日志切面类

import javax.servlet.http.HttpServletRequest;
import org.apache.struts2.ServletActionContext;
import org.aspectj.lang.ProceedingJoinPoint;
import com.opensymphony.xwork2.ActionContext;
/**
 * 日志记录仪
 */
public class Logger {
    private LogService logService ;
    //注入logService
    public void setLogService(LogService logService) {
        this.logService = logService;
    }
    /**
     * 记录日志 
     */
    public Object record(ProceedingJoinPoint pjp){
        Log log = new Log();
        try {
            ActionContext ac = ActionContext.getContext();
            //operator
            if(ac != null){
                HttpServletRequest req = (HttpServletRequest) ac.get(ServletActionContext.HTTP_REQUEST);
                if(req != null){
                    User user = (User) req.getSession().getAttribute("user");
                    if(user != null){
                        log.setOperator("" + user.getId() + ":" + user.getEmail());
                    }
                }
            }
            //operName,方法名
            String methodName = pjp.getSignature().getName();
            log.setOperName(methodName);
            //operParams,方法参数列表
            Object[] args = pjp.getArgs();
            log.setOperParams(StringUtil.arr2Str(args));
            //调用目标对象的方法
            Object ret = pjp.proceed();
            //operResult,成功
            log.setOperResult("success");
            //resultMsg,结果消息
            if(ret != null){
                log.setResultMsg(ret.toString());
            }
            return ret ;
        } catch (Throwable e) {
            log.setOperResult("failure") ;
            log.setResultMsg(e.getMessage());
        }
        finally{
            logService.saveEntity(log);//保存日志的service方法
        }
        return null ;
    }
}

2，spring配置文件中写法
