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

    		<property name="logService" ref="logService" />
    	</bean>
    	
    	
    	<aop:config>

    		<aop:aspect id="loggerAspect" ref="logger" order="1">
