问题描述
我的配置文件如下：<?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"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.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx-2.5.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"> <tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/> <context:annotation-config/> <context:component-scan base-package="com.len"> </context:component-scan> <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="persistenceXmlLocation" value="WEB-INF/jpa.xml"/> <property name="dataSource" ref="dataSource" /> <property name="jpaVendorAdapter"> <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> <property name="database" value="MYSQL" /> <property name="showSql" value="false" /> </bean> </property> </bean> <bean id="entityManagerAdvisor"class="org.springframework.aop.support.DefaultPointcutAdvisor"><property name="advice"><bean class="org.springframework.orm.jpa.JpaInterceptor" autowire="byName" /></property></bean><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://127.0.0.1:3306/apkbak?useUnicode=true&characterEncoding=utf8"/> <property name="username" value="root"/> <property name="password" value=""/> <property name="initialSize" value="20"/> <property name="maxActive" value="100"/> <property name="maxIdle" value="20"/> <property name="minIdle" value="0"/> <property name="testOnBorrow"><value>true</value></property> <property name="validationQuery"><value>SELECT 1 FROM DUAL</value></property></bean><bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory" /> </bean> <aop:aspectj-autoproxy proxy-target-class="true"></aop:aspectj-autoproxy></beans>启动的时候报错：信息: Initializing Spring root WebApplicationContextlog4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).log4j:WARN Please initialize the log4j system properly.2013-2-27 17:37:21 org.apache.catalina.core.StandardContext listenerStart严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListenerorg.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'org.springframework.transaction.annotation.AnnotationTransactionAttributeSource#0': Bean with name 'org.springframework.transaction.annotation.AnnotationTransactionAttributeSource#0' has been injected into other beans [org.springframework.transaction.config.internalTransactionAdvisor] in its raw version as part of a circular reference, but has eventually been wrapped. This means that said other beans do not use the final version of the bean. This is often the result of over-eager type matching - consider using 'getBeanNamesOfType' with the 'allowEagerInit' flag turned off, for example.at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:546)at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:456)at org.springframework.beans.factory.support.AbstractBeanFactory$1.getObject(AbstractBeanFactory.java:291)at org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:222)at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:288)at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:190)at org.springframework.beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons(DefaultListableBeanFactory.java:580)at org.springframework.context.support.AbstractApplicationContext.finishBeanFactoryInitialization(AbstractApplicationContext.java:895)at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:425)at org.springframework.web.context.ContextLoader.createWebApplicationContext(ContextLoader.java:276)at org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:197)at org.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:47)at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4205)at org.apache.catalina.core.StandardContext.start(StandardContext.java:4704)at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1053)at org.apache.catalina.core.StandardHost.start(StandardHost.java:840)at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1053)at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:463)at org.apache.catalina.core.StandardService.start(StandardService.java:525)at org.apache.catalina.core.StandardServer.start(StandardServer.java:754)at org.apache.catalina.startup.Catalina.start(Catalina.java:595)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)at java.lang.reflect.Method.invoke(Unknown Source)at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:289)at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:414)2013-2-27 17:37:21 org.apache.catalina.core.StandardContext start严重: Error listenerStart2013-2-27 17:37:21 org.apache.catalina.core.StandardContext start严重: Context [/wett] startup failed due to previous errors如果不加入： <aop:aspectj-autoproxy proxy-target-class="true"></aop:aspectj-autoproxy>便能运行，，为什么呢。请大侠们看看，，我需要用到aop...
解决方案
如果用的是SpringMVC ，在加载dispatcherServlet这个servlet的时候，也有一个配置文件<servlet-name>-servlet.xml，将AOP 配置 <aop:aspectj-autoproxy proxy-target-class="true"></aop:aspectj-autoproxy> 放在上面的xml文件中，试试。
