应该是配置文件的问题

[-yi--鸣-]

我的配置文件如下： <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"> <!-- 配置数据源 --> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"></property> <property name="url" value="jdbc:mysql://localhost/springmvc"></property> <property name="username" value="root"></property> <property name="password" value="root"></property> </bean> <!-- 配置SessionFactory --> <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.format_sql">true</prop> </props> </property> <!-- 注解扫描的包 --> <property name="annotatedClasses"> <list> <value>ne.springmvc.entity.User</value> </list> </property> </bean> <!-- 配置一个事务管理器 --> <bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> <!-- 配置事务，使用代理的方式 --> <bean id="transactionProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" abstract="true"> <property name="transactionManager" ref="transactionManager"></property> <property name="transactionAttributes"> <props> <prop key="add*">PROPAGATION_REQUIRED,-Exception</prop> <prop key="modify*">PROPAGATION_REQUIRED,-myException</prop> <prop key="del*">PROPAGATION_REQUIRED</prop> <prop key="*">PROPAGATION_REQUIRED</prop> </props> </property> </bean> </beans>

<!-- 注解扫描的包 --> <property name="annotatedClasses"> <list> <value>ne.springmvc.entity.User</value> </list> </property> 注解只扫描这一个类？

[奄灬苟且偷生]

不会是 ne.springmvc.entity.User少打了一个了吧 ne.springmvc.entity.User.*换成这个试试
