后台如何取response中的值

[yanxin9210]

在使用spring aop的自定义注解开发系统日志功能，需求是要监控操作时间、操作人、模块、动作、请求ip、请求浏览器、操作结果。

前几个值都可以从request和session中获取，而操作结果就必须要从response中获取。

现在的问题是：我已经在过滤器中取到了response，并且传给切点类了，但是不知道如何去取response里面的success值。

后台是spring+spring mvc+hibernate，前台是Extjs5

后台controller代码

@Override
@RequestMapping(value = "/saveDepartment", method = {RequestMethod.POST, RequestMethod.GET})
@SystemLogAfter //自定义注解
public void doSave(Department entity, HttpServletRequest request, HttpServletResponse response) throws IOException {
	ExtJSBaseParameter parameter = ((ExtJSBaseParameter) entity);
	// 查找所有父节点id相同（即同级节点）结果集
	List<Department> departmentList =  departmentService.queryByProerties("parentId", entity.getParentId());
	System.out.println("entity:" + entity.getDepId());
	System.out.println("entity:" + entity.getName());
	boolean isExist = false;
	// 遍历结果集
	if (departmentList.size() > 0) {
		for (Department department : departmentList) {
			// 查找新增项或修改项的组织机构名是否与其他同级机构同名
			System.out.println(department.getDepId());
			System.out.println(department.getName());
			System.out.println(department.getName().equals(entity.getName()));
			System.out.println(department.getDepId().equals(entity.getDepId()));
			if (department.getName().equals(entity.getName()) && !department.getDepId().equals(entity.getDepId())) {
				isExist = true;
				break;
				//return;
			}
		}
	}
	
	if (!isExist) {
		if (CMD_EDIT.equals(parameter.getCmd())) {
			departmentService.update(entity);
		} else if (CMD_NEW.equals(parameter.getCmd())) {
			departmentService.persist(entity);
		}
		parameter.setCmd(CMD_EDIT);
		parameter.setSuccess(true);  //操作成功
	}
	else{
		parameter.setSuccess(false);  //操作失败
	}
	writeJSON(response, parameter);  //生成json数据是用的jackson框架
}

前台js可以获取到response中的success值

Ext.Ajax.request({
	url : appBaseUri + '/sys/department/saveDepartment',
	params : {
		cmd : vals['cmd'],
		depId : vals['depId'],
		name : vals['name'],
		parentId : vals['parentId'],
		manager : vals['manager'],
		tel : vals['tel'],
		sortId : vals['sortId'],
		memo : vals['memo']
	},
	method : "POST",
	success : function(response) {
		if (response.responseText != '') {
			var res = Ext.JSON.decode(response.responseText); //获取response中的json数据
			if (res.success) {
				globalObject.msgTip('操作成功！');
				Ext.getCmp('departmentmanagementgrid').getStore().reload();
				Ext.getCmp('departmentTree').getStore().reload();
			} else {
				globalObject.errTip('当前部门名称已存在！');
			}
		}
	},
	failure : function(response) {
		globalObject.errTip('操作失败！');
	}
});

切点类

@Aspect  
@Component  
public class SystemLogAfterAspect {
	
	@Resource
	private SysLogService sysLogService;
	
	@Resource
	private AuthorityService authorityService;

	// Controller层切点
	@Pointcut("@annotation(com.djbh.aop.SystemLogAfter)")
	public void controllerAspect() {
	}
	
	/**
	 * 后置通知 用于拦截Controller层记录用户的操作
	 * 
	 * @param joinPoint 切点
	 */
	@After("controllerAspect()")
	public void doAfter(JoinPoint joinPoint) {
		
		//使用SystemContextUtils工具类获取request  response  session
		HttpServletRequest request = HttpContextUtils.getRequest();
		HttpServletResponse response = HttpContextUtils.getResponse();
		HttpSession session = HttpContextUtils.getSession();
		
		// 读取session中的用户
		SysUser sysUser = (SysUser)session.getAttribute(Constant.SESSION_SYS_USER);
		
		// 读取cmd值，cmd = new 或 edit，用来判断是新增保存还是修改保存
		String cmd = request.getParameter("cmd");
		String url = request.getRequestURI();
		String contextPath = request.getContextPath() + "/";
		// 请求的模块
		String model = null;
		// 请求的动作
		String action = null;
		System.out.println(url);
		if (StringUtils.isNotBlank(url)) {
			url = url.replace(contextPath, "");
			// 正则表达式
			Pattern p = Pattern.compile("[/]+");
			// 将url字符串按/分割成字符串数组
			String[] urls = p.split(url);
			for (int i = 0; i < urls.length; i++) {
				System.out.println(i+":" + urls[i]);
			}
			// 组合需要格式的字符串
			StringBuffer sbUrl = new StringBuffer(urls[0]).append(".").append(urls[1]);
			System.out.println(sbUrl);
			Authority authority = authorityService.getByProerties("url", sbUrl.toString());
			
			model = authority == null ? "其他" : authority.getMenuName();
			
			if (urls[2].startsWith("get")) {
				action = "查询（获取）";
			}
			else if (urls[2].startsWith("save") && "new".equals(cmd)) {
				action = "新增";
			}
			else if (urls[2].startsWith("save") && "edit".equals(cmd)) {
				action = "修改";
			}
			else if (urls[2].startsWith("delete")) {
				action = "删除";
			}
			else if (urls[2].startsWith("login")) {
				action = "登录";
			}
			else if (urls[2].startsWith("logout")) {
				action = "注销";
			}
			else {
				action = "其他";
			}
		}
		
		// 请求的IP
		String ip = request.getRemoteAddr();
		
		// 请求的浏览器
		String webBrower = request.getHeader("User-Agent");
		
		try {
			// *========控制台输出=========*//
			System.out.println("=====后置通知开始=====");
			System.out.println("用户名:" + sysUser.getUserName());
			System.out.println("姓名:" + sysUser.getRealName());
			System.out.println("请求IP:" + ip);
			System.out.println("浏览器:" + webBrower);
			System.out.println("请求方法:"
					+ (joinPoint.getTarget().getClass().getName() + "."
							+ joinPoint.getSignature().getName() + "()"));
			System.out.println("url:" + url);
			System.out.println("模块:" + model);
			System.out.println("动作:" + action);
			System.out.println("cmd:" + cmd);
			
			// *========数据库日志=========*//
			SysLog sysLog = new SysLog();
			SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
			sysLog.setLogTime(sdf.format(new Date()));
			sysLog.setUserName(sysUser.getUserName());
			sysLog.setRealName(sysUser.getRealName());
			sysLog.setIp(ip);
			sysLog.setWebBrower(webBrower);
			sysLog.setModel(model);
			sysLog.setAction(action);
			
			// 保存数据库
			sysLogService.persist(sysLog);
			System.out.println("=====后置通知结束=====");
		} catch (Exception e) {
			// 记录本地异常日志
			// logger.error("==前置通知异常==");
			// logger.error("异常信息:{}", e.getMessage());
		}
	}
}

我在切点类中获得了response对象，怎么去取controller中的parameter的success值呢？请高人指点啊！

已经通过将操作结果放到request中实现了系统日志操作结果的监控

HttpContextUtils是怎么写得

[liumanjiangjiahe]

@AfterReturning(pointcut="execution(* com.abc.service.*.many*(..))", returning="returnValue") public void log(JoinPoint point, Object returnValue) { System.out.println("@AfterReturning：模拟日志记录功能..."); System.out.println("@AfterReturning：目标方法为：" + point.getSignature().getDeclaringTypeName() + "." + point.getSignature().getName()); System.out.println("@AfterReturning：参数为：" + Arrays.toString(point.getArgs())); System.out.println("@AfterReturning：返回值为：" + returnValue); System.out.println("@AfterReturning：被织入的目标对象为：" + point.getTarget()); }
