问题描述：

Hibernate + Springmvc，配置了AOP如下：

<aop:config> <aop:pointcut id="userDaoPointCut" expression="execution(* com.mkyong.users.service.*Dao.*(..))" /> <aop:advisor advice-ref="txAdvice" pointcut-ref="userDaoPointCut" /> </aop:config> build时报错 ClassNotFoundException: org.aspect.weaver...

caused by: java.lang.NoClassDefFoundError: org/aspectj/weaver/reflect/ReflectionWorld$ReflectionWorldException at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Unknown Source) at java.lang.Class.getConstructor0(Unknown Source) at java.lang.Class.getDeclaredConstructor(Unknown Source) at org.springframework.beans.factory.support.SimpleInstantiationStrategy.instantiate(SimpleInstantiationStrategy.java:78) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.instantiateBean(AbstractAutowireCapableBeanFactory.java:1030) ... 47 more Caused by: java.lang.ClassNotFoundException: org.aspectj.weaver.reflect.ReflectionWorld$ReflectionWorldException at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1680) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1526) ... 53 more

原因和解决：

由于缺少 spring-aspects 的jar包，需要在pom.xml中声明： pom.xml <properties> <spring.version>3.2.8.RELEASE</spring.version> </properties> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${spring.version}</version> </dependency> </dependencies>
