Spring Aop 能切入jar包中的某个类的某个方法吗 5C

有看过网上的一些介绍,尝试着把这个类交由Spring去管理,并配置为多例的(经常new),写了测试,bean注入成功,但是切点切不进去,aop这块写的没有问题,自己有测试,求大神指点

4个回答

首先你自己new出来的类,是不能进入到spring容器中的,可以使用XML配置的方式或者@Bean注解的方式,注入到Spring容器中;
Spring AOP配置也有两种方式,XML配置方式和注解的方式,其中注解的方式比较灵活,可以实现更多的逻辑

完全可以,你要写好表达式pointcut

走走不完的路,看看不完的景 表达式写的完全没有问题,自己项目中的和jar包中的表达式一个套路,jar包中的切不进去

自定义一个注解,在方法上使用注解,写一个@Aspect的类,定义pointCut,aroundAdvice

new的话 就不行了

Spring aop可以拦截封装好的jar包里的程序吗?

Spring aop可以拦截封装好的jar包里的程序吗?比如jdbc驱动包里的Driver.connect()方法

怎么把一个jar包里的类交给spring管理并进行aop

我对spring不太熟悉,所以也不知道这个需求是不是有点奇怪:现在有个jar包,我们自己写的类继承自jar包里的某个类,平时使用就是new一个对象出来,能不能将jar包里的这个类让spring管理进行aop,这样子类调用父类的方法都能切到?如果spring不行有没有其它方法实现这个需求(对于子类必须是透明的,还是照常new使用,只是调用父类方法能被拦截)?

spring的aop切面拦截第三方jar的问题

@Pointcut("execution(public * org.hibernate..*.*(..) ) ") 我想通过上面的切面路径拦截hibernate的方法的执行,但是一直拦截不到,这样写有问题吗? 拦截自己写的类的方法可以,拦截上面的失效,请高手指点下

关于spring aop的cglib代理什么时候才起作用

网上的文章都说 <aop:aspectj-autoproxy proxy-target-class="true"></aop:aspectj-autoproxy>配置了这句话的话就会强制使用cglib代理,如果proxy-target-class改成"false"的话就会先使用jdk动态代理如果不是接口来实现的话再使用cglib代理,但是我实验的时候如果proxy-target-class改成false的话永远是使用jdk动态代理啊,我也加了cglib的jar包了,这是为什么啊 难道网上说的都是错的?

AOP与IOC的冲突/aop无法注入

项目架构同时搭建spring 和 spring mvc 在分库架构体系下我打算用aop来实现分库的实现流程, 我在spring xml里扫描了service,在mvc xml里扫描了controller 于是在mvc里配置aop 切面aspect可以设定service为切入目标 但是在spring里配置aop 切面aspect既不能设定service也不能设置controller为切入点 注:使用了@controller @service注解 问题在于,无论我是在mvc里切入service,还是在spring里切入dao,程序能够正常启动但是无法正常切入,打印切面的代码。配置文件可以识别切面的目标 不知道是配置文件的错误还是jar包冲突导致的 ``` <context:component-scan base-package="com.**.web,com.gm.spring.aop.log"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/> </context:component-scan> <aop:aspectj-autoproxy proxy-target-class="true"/> <bean id="logAspect" class="com.gm.spring.aop.log.LogAspect" /> <bean class="org.springframework.aop.aspectj.annotation.AnnotationAwareAspectJAutoProxyCreator" /> ``` ```@Component @Aspect public class LogAspect { //Logger logger = Logger.getLogger(gm_log.class); //String logStr = null; @Before("execution(* com.core.user.service..*(..))") public void doBefore(JoinPoint jp){ /* logStr = jp.getTarget().getClass().getName() + "类的" + jp.getSignature().getName() + "方法开始执行 ****Start****"; logger.info(logStr);*/ System.out.println("执行执行执行执行执行执行执行执行执行执行"); } } ``` ```@Service @Transactional public class sysMenuService { @Autowired private sysMenuMapper mapper; public List<sysMenu> getMenu(){ return mapper.getMenu(); } ```

Spring注解实现Aop,找不到@Pointcut注解下的方法标签

各类中感觉是没有什么问题,我也查找了很多相关资料,也未能发现问题所在。 使用的是Eclipse,jdk8。 此项目导入了aspectjrt.jar、aspectjweaver.jar、cglib-nodep-2.1_3.jar、spring-2.5.jar。 我也换过其它版本的Spring包,问题照旧。 求大神们帮忙看看是什么情况,谢谢 ![此为抛出的异常,此异常是说在@berfore中没有找到自己定义的那个@Pointcut方法标签??可以这样理解吗](https://img-ask.csdn.net/upload/201708/24/1503564328_211138.png) ![切面类](https://img-ask.csdn.net/upload/201708/24/1503564385_377781.png) ![xml配置](https://img-ask.csdn.net/upload/201708/24/1503564409_528944.png) ![测试类](https://img-ask.csdn.net/upload/201708/24/1503565946_414294.png) ![实现了接口](https://img-ask.csdn.net/upload/201708/24/1503566056_989089.png)

ehcache+springAOP配置不成功?

刚接触ehcache缓存框架,在网上看了一些例子(不过发现所有的例子都是那么一个,只是在不停地转载。真不知道那些转的人到底有没有实际操作过?)springAOP 拦截注入的时候报错,一时 不知道 怎么解决,大家来看看,交流下! 开始使用 springMVC注解的方式配置ehcache,发现虽然配置成功但是缓存不起作用,后面想想 还是用springAOP来试试。相关配置如下: cacheContext.xml(拦截器配置): <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans> <!-- 引用ehCache的配置 --> <bean id="defaultCacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean"> <property name="configLocation"> <value>ehcache.xml</value> </property> </bean> <!-- 定义ehCache的工厂,并设置所使用的Cache name --> <bean id="ehCache" class="org.springframework.cache.ehcache.EhCacheFactoryBean"> <property name="cacheManager"> <ref local="defaultCacheManager"/> </property> <property name="cacheName"> <value>DEFAULT_CACHE</value> </property> </bean> <!-- find/create cache拦截器 --> <bean id="methodCacheInterceptor" class="ehcache.scada.utils.MethodCacheInterceptor"> <property name="cache"> <ref local="ehCache" /> </property> </bean> <!-- flush cache拦截器 <bean id="methodCacheAfterAdvice" class="ehcache.scada.utils.MethodCacheAfterAdvice"> <property name="cache"> <ref local="ehCache" /> </property> </bean>--> <bean id="methodCachePointCut" class="org.springframework.aop.support.RegexpMethodPointcutAdvisor"> <property name="advice"> <ref local="methodCacheInterceptor"/> </property> <property name="patterns"> <list> <value>.*find.*</value> <value>.*get.*</value> </list> </property> </bean> <!-- <bean id="methodCachePointCutAdvice" class="org.springframework.aop.support.RegexpMethodPointcutAdvisor"> <property name="advice"> <ref local="methodCacheAfterAdvice"/> </property> <property name="patterns"> <list> <value>.*save.*</value> <value>.*insert.*</value> <value>.*update.*</value> <value>.*delete.*</value> <value>.*remove.*</value> </list> </property> </bean> --> </beans> 上面配置中的两个拦截器 在工具类中都写有相关实体 bean MethodCacheInterceptor.java MethodCacheAfterAdvice.java springContext.xml(切入点配置): <import resource="cacheContext.xml"/> <bean id="testServiceTarget" class="hqhop.scada.daos.res.impl.ResDaoImpl"/> <bean id="testService" class="org.springframework.aop.framework.ProxyFactoryBean"> <property name="target"> <ref local="testServiceTarget"/> </property> <property name="interceptorNames"> <list> <value>methodCachePointCut</value> <!--<value>methodCachePointCutAdvice</value>--> </list> </property> </bean> 并在web.xml中加载了 springContext.xml 也有ehcache相关的jar 最后启动项目 报错: Caused by: org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.cache.ehcache.EhCacheFactoryBean]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory (当然还有其他错,但是我觉得 这个是罪魁祸首)

proxy-target-class="true"> <aop:advisor advice-ref="txAdvice" pointcut="execution (* com.mobile.dao.*.*(..))"/>[/code] </aop:config> 这种方式我试过了。也会出错。 [b]4:其二,既然你要用注解的方式,那么你就要在你的项目中,加入这两个jar包:aspectjweaver.jar aspectjrt.jar 我好像没加这两个包。我加加试试。[/b] 5:配置文件哪里有问题?如果我不在接口或类上加@Transactional 就是完全正确的运行。 谢谢!请帮忙! [b]问题补充:[/b] [b]再补充:两个包我加了,还是一样的错误。而且那两个包是aop才需要的吧?[/b] [b]问题补充:[/b] [b][color=darkred]yangtao309[/color][/b] 按照你说的把那个多余的连接池delete了。程序不会出错了。 但是不会回滚事务? 那我另问一下:[color=blue]我把@Transactional(readOnly=false) public Response addCustomer(VisCustomer cut) 放在一个接口的实现类的方法上面,那是不是就说我这个方法体都具有一个相同的事务呢?只要其中一个地方出错整个方法都执行失败? 因为我这个方法内不止使用了一个dao的一个方法,有多个方法。比如我现在有 table1,table1-2(关系表),table2 我现在要操作table1,给其insert ,insert之后要向 table1-2中添加一条数据,这时我添加table1-2时出错了,那么我操作table1的数据可以回滚吗? [/color] [b]问题补充:[/b] [b]我添加table1-2时并没有异常,是在数据库中被回滚的,程序中执行是正确的。这样能把它在程序中就回滚了吗?我正在看spring2.5的开发参考手册,其中rollbackForClassname 是定义一组类的名字,必须是Throwable的子类,遇到时必须回滚。如果我产生不了异常不就是说还是回滚不了?[/b] [b]问题补充:[/b] [quote]@Transactional(readOnly=false,rollbackFor = Throwable.class)[/quote] 不能回滚事务。肯定还有地方不对。但是配置我想是没问题了。看了api现在完全按照上面来了。非常非常感谢[color=olive]yangtao309 [/color]
