有删节：只复制了前半部分。级别有限只能发这些字。。
急~~高手快来吧。。注：文件都有，有人说要更新JAR包我也下了。没用。。
有可能的话可以描素spring habernate Struts框架存放的位置如：spring直接放在根目录或***
谢谢，因为有的人说跟放的位置也有一点关系。不知道是不是。
所以方便的话给个大置框架位置。
对了我用Habernate反向生成实体类时，不在我指定的entity包中而在存在了default包中

Answer 1

这个可能是你添加Spring的配置文件没有配置好，导致Action中没有传入值。可以参考一下这个配置对比一下
<beans>

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
<property name="url" value="jdbc:sqlserver://localhost:1433;DataBaseName=zf" />
<property name="username">
<value>sa</value>
</property>
<property name="password">
<value>sa</value>
</property>
</bean>

<!-- 定义一个sessionFactory Bean -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref local="dataSource"/>
</property>
<property name="mappingResources">
<list>
<value>com/aptech/jb/entity/FWXX.hbm.xml</value>
<value>com/aptech/jb/entity/QX.hbm.xml</value>
<value>com/aptech/jb/entity/USER.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.SQLServerDialect
</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>
<!-- 1,dao层注入 -->
<bean id="fwxxDAO" class="com.aptech.jb.dao.hibimpl.FwxxDAOhibImpl">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<bean id="userDAO" class="com.aptech.jb.dao.hibimpl.UserDAOhibImpl">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>

<!-- Target -->
<bean id="fwxxBizTarget" class="com.aptech.jb.biz.impl.FwxxBizImpl">
<property name="fwxxDao" ref="fwxxDAO"></property>
</bean>
<bean id="userBizTarget" class="com.aptech.jb.biz.impl.UserBizImpl">
<property name="userDao" ref="userDAO"></property>
</bean>

<!-- 2,biz 在这里"侵入"原来的配置，本来是注入"fwxxDao"的-->
<bean id="fwxxBiz" parent="baseTransProxy">
<property name="target" ref="fwxxBizTarget" />
</bean>
<bean id="userBiz" parent="baseTransProxy">
<property name="target" ref="userBizTarget" />
</bean>

<!-- 3,Action层注入 -->
<bean name="/fwxx" class="com.aptech.jb.web.action.FwxxAction">
<property name="fwxxBiz" ref="fwxxBiz"></property>
</bean>
<bean name="/user" class="com.aptech.jb.web.action.UserAction">
<property name="userBiz" ref="userBiz"></property>
</bean>

<!-- Spring1.x的声明式事务,声明一个事务管理器 -->
<bean id="MyHibTransactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>

<bean id="baseTransProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" abstract="true">
<property name="transactionManager" ref="MyHibTransactionManager" />
<property name="transactionAttributes">
<props>
<prop key="insert*">PROPAGATION_REQUIRED</prop>
<prop key="delete*">PROPAGATION_REQUIRED</prop>
<prop key="modify*">PROPAGATION_REQUIRED</prop>
<prop key="do*">PROPAGATION_REQUIRED</prop>
<prop key="*">PROPAGATION_SUPPORTS,readOnly</prop>
</props>
</property>
</bean>

</beans>

Answer 2

org.hibernate.DuplicateMappingException: Duplicate class/entity mapping Achievement
Caused by: org.hibernate.DuplicateMappingException: Duplicate class/entity mapping Achievement

Achievement 这个类有两个副本，或者就是你copy/paste错误，检查一下吧

Answer 3

看一下你的Hibernate配置文件中是否有多个重复的Achievement映射。如果有，删掉其他，只保留一个

Answer 4

[applicationContext.xml这个配置文件有误，不能创建SESSIONFACTORY配置文件的问题。 你的某个配置文件是不是重复配置了，好像是HIBERNATE的配置文件

Answer 5

jar包冲突了吧

Answer 6

spring habernate Struts
