    String[] propNames() default {};
}

3.切面类

@Component
@Aspect
public class ParameterVerify {
    @Autowired
    private ObjUtil objUtil;

    @Around(value = "@args(com.example.obj.obj_manager.parameter_verify.prop_not_null.PropNotNull)")
    public Object before(ProceedingJoinPoint pjp) throws Throwable {
        System.out.println(1111);
        Object ret = pjp.proceed();
        return ret;
    }
}

spring aop报错:Cannot proxy target class because CGLIB2 is not available.
今天在整合spring aop时报了这个错: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpwordDao' defined in ServletContext resource [/WEB-INF/config/spring/data-access-config.xml]: Initialization of bean failed; nested exception is org.springframework.aop.framework.AopConfigException: Cannot proxy target class because CGLIB2 is not available. Add CGLIB to the class path or specify proxy interfaces. 调查发现应该是缺少包:cglib-nodep-2.2.jar 但是将其加入到buildpath中后还是报同一个错误,估计可能是Spring中的cglib-nodep-2.x.x.jar与Hibernate中的cglib-2.2.jar相冲突,这时需要保留spring的,取消hibernate的,但是查了一遍lib,没有发现hibernate的cglib-2.2.jar,这就不懂是什么情况了,请问谁知道是怎么回事

在Spring AOP中,关于 [为通知传递参数] 的配置问题
下面是aop:config的配置 ``` <aop:config> <aop:aspect ref="magician"> <aop:pointcut id="thinking" expression="execution(* com.springinaction.springidol.Volunteer.thinkOfSomething(String)) and args(thoughts)" /> <aop:before method="interceptThoughts" arg-names="thoughts" pointcut-ref="thinking"/> </aop:aspect> </aop:config> ``` 下面是我的问题 1. 按照切点的表达式,我们可以知道thinkOfSomething(String)方法有一个String参数,那么在匹配切面中的方法的时候,根据配置可以知道方法名是interceptThoughts,那么再检查该方法是否有且只有一个String参数不就行了,为什么还要在切点中配置"args(thoughts)",在通知方法配置属性arg-names="thoughts",而且要求字符串“thoughts”是一致的,而不是作为一个占位。 2. 假设配置args(thoughts)只是为了说明该切点需要传递参数和传递参数的个数(比如说thoughts只是占位,表明传递第一个参数),那么根据参数的个数和对应的类型就可以匹配到通知方法了。那么,arg-names="thoughts" 就是多余的了。 上面就是我的疑问,有一种情况是我试验可以成功的,那就是切点不配置args(thoughts),通知方法不配置arg-names="thoughts",并且通知方法interceptThoughts是个无参函数,这个情况是可以的。 总而言之,关于通知方法的匹配逻辑我很模糊,希望大神指点。
spring aop的效果是在哪里起作用的。
1:spring初始化bean的时候 。判断该bean是否被切面 切,如果切了 就生成对应aop的代理。 2:spring初始化的时候生成普通的bean,在getBean的时候 去判断是否被切面。 所以aop在以上哪种情况? 可以附上源码解释吗。或者url

学习Spring AOP的时候,只有加入<aop:config>到xml中,test就无法运行
学习Spring AOP的时候,只有加入<aop:config>到xml中,test就无法运行 菜鸟入门,多多指教。 Xml配置aop的时候可以自动联想出来,不会报错 抛出异常如下 ``` 十二月 31, 2018 4:12:16 下午 org.springframework.context.support.AbstractApplicationContext refresh 警告: Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.aop.aspectj.AspectJPointcutAdvisor#0': Cannot create inner bean '(inner bean)#365185bd' of type [org.springframework.aop.aspectj.AspectJMethodBeforeAdvice] while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#365185bd': Resolution of declared constructors on bean Class [org.springframework.aop.aspectj.AspectJMethodBeforeAdvice] from ClassLoader [sun.misc.Launcher$AppClassLoader@4aa298b7] failed; nested exception is java.lang.NoClassDefFoundError: org/aspectj/lang/JoinPoint ``` XML配置如下 ``` <?xml version="1.0" encoding="UTF-8"?> <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" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd" > <bean id="aspectBiz" class="baseClass.AspectBiz" scope="prototype"></bean> <bean id="aspect" class="baseClass.Aspect" scope="prototype"></bean> <!-- 切面配置 --> <aop:config> <aop:aspect id="aopAspect" ref="aspect"> <aop:before method="before" pointcut-ref="bizPointCut"/> <aop:pointcut expression="execution(* baseClass.*Biz *(..))" id="bizPointCut"/> </aop:aspect> </aop:config> </beans> ``` 如果注释掉切面配置的话就能通过getBeans获得对象且正常运行..
关于spring中AOP切入点表达式问题
``` @Before("execution(* xxx.controller..*(..)") public void logController2(){ System.out.println("控制层注入"); } @Before("within(xxx.service..*)") public void logService(){ System.out.println("业务层注入"); } ``` 不知道为什么后一个within在容器启动时就会调用10次左右,![图片说明](https://img-ask.csdn.net/upload/201807/07/1530974872_839802.png), 然后调用一次service请求也会调用它好多次,正常对我这个程序而言应该只有两次才对,而上一个execution则是正常的,如果我不使用注解使用xml配置那么within则可以正常使用,真是郁闷,我新手,搞不懂为什么.!![图片说明](https://img-ask.csdn.net/upload/201807/07/1530974914_642651.png)请大神帮忙看一下 //补充一下,我的问题是为什么使用within(..*)以后会出现调用切面很多次的原因,不是问使用的格式!然后新发现使用@Around环绕使用within指定service直接所有service接口报错-说什么关于接口“xxx”的静态初始化不支持编译器限制的错误.

spring aop 事务拦截问题
spring boot 在spring中配置aop 事务管理,其中有一条是这样的 ``` source.addTransactionalMethod("is*", txAttr_REQUIRED_READONLY); ``` 配置了这个之后,如果接口中有方法是以“is”开头的,那么它的事务就被设置成只读 我的问题是:如果我偏要用“is”开头来命名一个方法,那我可以用什么样的注解或者其它方式,将该方法设置成不是只读。 自己测试过了,在方法前面添加 **@Transactional(readOnly = false)** 并没有作用

Java如何在Spring AOP中返回Map
## **Java如何在Spring AOP中返回Map** 各路Java业界大神,请帮小弟一把。 在spring mvc的控制器中,需要频繁返回Map<String,String>来反应前端网页是否修改成功。 所以我就想做一个AOP控制所有的void delete*()等方法实现自动加上Map类型返回。 以下是未修改代码: @RequestMapping("delete") @ResponseBody public Map<String,String> delete(Integer id){ Map<String,String> tipMessages=new HashMap<String,String>(); try{ xxxService.delete(Integer id); tipMessages.put("status", "Y"); tipMessages.put("info","删除成功"); }catch(Exception e){ tipMessages.put("status", "N"); tipMessages.put("info", "删除失败"); } return tipMessages; 理想状态: @Around("pointCut()") public Object doAround(ProceedingJoinPoint pjp) throws Throwable { try{ Object o = pjp.proceed(); //正常处理 tipMessages.put("status", "Y"); tipMessages.put("info","删除成功"); }catch(Exception e){ tipMessages.put("status", "N"); tipMessages.put("info", "删除失败"); } return o; } Class xxxService{ public Map<String,String> delete(){ xxxRepository.delete(); } } 不知从何下手,望大神门指点迷津。
