最近搭建一個ssh的通用架子時,想做個通用日誌的攔截方法,可以利用反射獲取攔截類中的屬性

不多說,上程式碼

日誌類

public class MyLog {
	public void doBefore(JoinPoint jp) throws SecurityException, NoSuchFieldException, IllegalArgumentException, IllegalAccessException {
	Field f = jp.getTarget().getClass().getDeclaredField("username");//獲取屬性-->Field
 	f.setAccessible(true);//如果是私有的 先要設定可訪問
	String user = (String) f.get(jp.getTarget());//獲取值,這個get()方法重點是引數,引數是你要獲取的類
	logStr = user + " 進行了" + jp.getTarget().getClass().getName() + " 類的 "+ jp.getSignature().getName()+" 方法開始執行 ";logger.info(logStr);}
	}
}
 

攔截類

 com.xxx.xxx.controller包下的ServerManagerController.java

public class ServerManagerController extends BaseAction{
	
	private String username = "";
	@Autowired

	/**
	 * 管理頁面  
	 * @return
	 */
	@RequestMapping(value = "/toServerManager")
    public String toServerManager(){ 
		UserLogInfo user = (UserLogInfo)session.getAttribute("userLogInfo");
		this.username = user.getUsername();
        return "/jsp/examine/serverManager";
    }
}

    	配置日誌 使用Aop 記錄日誌    
    	注意:  
    	1). 此處proxy-target-class="true" 否則Action內的引數會被攔截掉,導致action內無法獲得前臺傳遞的引數   
    	2). Action需交給spring容器去管理
