5.措施

将切点表达式中的:@args()换成@annotation就不会报错了,能正常启动了。

6.请教

请教各位前辈,是什么原因导致idea启动不了项目的?是不是@args这个表达式有问题?

2个回答

找到问题了,原来是只使用@args(*.*.*.*)的时候,会匹配到spring中某些被final修饰过的类(具体为什么会匹配上,不详)。
因此需要在后面加个限定条件:@Around(value = "@args(com.example.demo.prop_not_null.PropNotNul)&& within(com.example.demo..*)")。
限定包名为自己的项目中的包,这样就能避免匹配到其他东西了

既然是空指针异常,那很大可能就是某个对象其实没有获得到,值为空,然后却又调用了该对象的方法,所以报错了(非常大的概率是这种情况)。你在报错信息里找找,看看提示的那一行报的空指针异常,也可以打断点,idea的断点很好用的,你看看那个对象为空,但是却调用了。

spring aop参数传递的问题

通过Spring 的AOP实现日志, 当通过反射获取方法对象时报错"NoSuchMethodFoundException"
![图片说明](https://img-ask.csdn.net/upload/201904/11/1554964364_603440.png) **下面的是controller中的方法** ``` @Controller @RequestMapping("/permission") public class PermissionController { @Autowired private

当执行到最后"method = clazz.getMethod(methodName,classArgs);"时报错. 我试过了, 如果没有参数则不会报错, 如果参数 是int基本数据类型也会报错, 换成Integer就不会报错** ``` @Autowired private SysLogService sysLogService; private Class clazz; //访问的类

为什么spring2.5 aop没有执行切入前后的方法呢?
<p>我在学习spring in action 这本书的aop的例子时,为什么我编译没有报错,但是却没有执行我切入前后的方法?</p> <p>xml配置代码如下:</p> <pre name="code" class="xml">&lt;beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"&gt; &lt;bean id= "quest" class ="com.knight.HolyGrailQuest"&gt; &lt;/bean&gt; &lt;bean id = "knight" class = "com.knight.KnightOfTheRoundTable"&gt; &lt;constructor-arg value='sotomi' /&gt; &lt;property name='quest' ref='quest'&gt;&lt;/property&gt; &lt;/bean&gt; &lt;bean id = "minstrel" class = "com.knight.Minstrel"&gt;&lt;/bean&gt; &lt;aop:config&gt; &lt;aop:aspect ref = 'minstrel' &gt; &lt;aop:pointcut id='questPointCut' expression='execution(* *.embarkOnQuest(..)) and target(bean)' /&gt; &lt;aop:before method='singBefore' pointcut-ref='questPointCut' arg-names = 'bean' /&gt; &lt;aop:after-returning method='singAfter' pointcut-ref='questPointCut' arg-names = 'bean' /&gt; &lt;/aop:aspect&gt; &lt;/aop:config&gt; &lt;/beans&gt;</pre> <p> Minstrel类的方法如下:</p> <pre name="code" class="java">public class Minstrel { private static final Logger Song = Logger.getLogger(Minstrel.class); public void singBefore(Knight knight){ Song.info("Knight is so brave!"); System.out.println("**********************before"); } public void singAfter(Knight knight){ Song.info("Knight did quest the grail!"); } }</pre> <p> </p> <p>测试main函数:</p> <pre name="code" class="java">public class Test { public static void main(String args[]){ BeanFactory factory = new XmlBeanFactory(new FileSystemResource("bean.xml")); Knight knight = (Knight)factory.getBean("knight"); knight.embarkOnQuest(); } }</pre> <p> 但是执行后没有打印结果,我哪里设置错误了么?</p>

ProxyFactory 调用getProxy方法报ClassNotFoudException
初学Spring 自己写了一个测试用Demo,但是报错,求助。可能是低级错误,轻喷。 import java.lang.reflect.Method; import org.springframework.aop.MethodBeforeAdvice; import org.springframework.aop.framework.AopConfigException; import org.springframework.aop.framework.ProxyFactory; import org.springframework.aop.interceptor.*; public class TestPointCut { public static void main(String[] args) { // TODO Auto-generated method stub DataSet ds = new DataSet(); MethodBeforeAdvice mba = new MethodBeforeAdvice() { @Override public void before(Method arg0, Object[] arg1, Object arg2) throws Throwable { // TODO Auto-generated method stub System.out.println("Before..."); } }; ProxyFactory pf = new ProxyFactory(); pf.setTarget(ds); try { pf.addAdvice(mba); } catch (AopConfigException e) { e.printStackTrace(); } DataSet result = (DataSet) pf.getProxy(); result.setName("Irwin"); } } class DataSet{ private String name; private String sex; private String age; public String getName() { System.out.println("getName"); return name; } public void setName(String name) { System.out.println("setName"); this.name = name; } public String getSex() { System.out.println("getSex"); return sex; } public void setSex(String sex) { System.out.println("setSex"); this.sex = sex; } public String getAge() { System.out.println("getAge"); return age; } public void setAge(String age) { System.out.println("setAge"); this.age = age; } } 错误的提示是: Caused by: java.lang.ClassNotFoundException: org.springframework.cglib.proxy.MethodInterceptor 求教我那里写错了?还是有缺失的jar包?
请大牛帮忙解决个问题,spring+jpa(全标注配置) 事务不回滚
在一个事务中,插入两条数据,有一条数据已存在数据库中,执行程序后应该发生异常,事务进行回滚,不插入数据库任何数据;但程序执行后发生了异常,但事务没有回滚,数据库又新增了一条数据,请大牛帮忙解决一下!

Linux(服务器编程):15---两种高效的事件处理模式(reactor模式、proactor模式)
前言 同步I/O模型通常用于实现Reactor模式 异步I/O模型则用于实现Proactor模式 最后我们会使用同步I/O方式模拟出Proactor模式 一、Reactor模式 Reactor模式特点 它要求主线程(I/O处理单元)只负责监听文件描述符上是否有事件发生,有的话就立即将时间通知工作线程(逻辑单元)。除此之外,主线程不做任何其他实质性的工作 读写数据,接受新的连接,以及处...
为什么要学数据结构?
一、前言 在可视化化程序设计的今天,借助于集成开发环境可以很快地生成程序,程序设计不再是计算机专业人员的专利。很多人认为,只要掌握几种开发工具就可以成为编程高手,其实,这是一种误解。要想成为一个专业的开发人员,至少需要以下三个条件: 1) 能够熟练地选择和设计各种数据结构和算法 2) 至少要能够熟练地掌握一门程序设计语言 3) 熟知所涉及的相关应用领域的知识 其中,后两个条件比较容易实现,而第一个...

进程通信方式总结与盘点
​ 进程通信是指进程之间的信息交换。这里需要和进程同步做一下区分,进程同步控制多个进程按一定顺序执行,进程通信是一种手段,而进程同步是目标。从某方面来讲,进程通信可以解决进程同步问题。 ​ 首先回顾下我们前面博文中讲到的信号量机制,为了实现进程的互斥与同步,需要在进程间交换一定的信息,因此信号量机制也可以被归为进程通信的一种方式,但是也被称为低级进程通信,主要原因为: 效率低:一次只可操作少量的...

双11不光是购物狂欢节,更是对技术的一次“大考”,对于阿里巴巴企业内部运营的基础保障技术而言,亦是如此。 回溯双11历史,这背后也经历过“小米加步枪”的阶段:作战室从随处是网线,交换机放地上的“一地狼藉”;到如今媲美5G的wifi网速,到现场却看不到一根网线;从当年使用商用AP(无线路由器),让光明顶双11当天断网一分钟,到全部使用阿里自研AP……阿里巴巴企业智能事业部工程师们提供的基础保障...

关于研发效能提升的思考
研发效能提升是最近比较热门的一个话题,本人根据这几年的工作心得,做了一些思考总结,由于个人深度有限,暂且抛转引入。 三要素 任何生产力的提升都离不开这三个因素:人、流程和工具,少了其中任何一个因素都无法实现。 人,即思想,也就是古人说的“道”,道不同不相为谋,是制高点,也是高层建筑的基石。 流程,即方法,也是古人说的“法”。研发效能的提升,也就是要提高投入产出比,既要增加产出,也要减...
