C++和蓝图1：Unreal Engine 中 C++ 与蓝图的桥梁摘要：本文介绍了Unreal Engine（UE）中C++与蓝图可视化脚本的结合机制，重点解析了宏系统（UCLASS、UPROPERTY、UFUNCTION）如何实现代码与蓝图的交互。相比Unity的纯C#脚本模式，UE的双轨制开发允许程序员用C++处理核心逻辑，同时通过蓝图让非程序员快速迭代。文章对比了两大引擎的编程范式差异，指出UE的反射系统和宏标记提供了更精细的控制，并给出了从Unity迁移到UE的具体思路。核心在于理解UE的混合编程优势：C++保证性能，蓝图提升开发效率，二者通过宏系统无缝协作。阅读详情

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
