关于事物的一个异常
这是我spring中事物的配置：

<!-- 配置事物 -->
<bean id="transactionManager" class="org.springframework.transaction.interceptor.TransactionInterceptor">
<property name="sessionFactory">
<ref local="sessionFactory"/>
</property>
</bean>

<bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor">
<!-- 事务拦截器bean需要依赖注入一个事务管理器 -->
<property name="transactionManager" ref="transactionManager" />
<property name="transactionAttributes">
<!-- 下面定义事务传播属性 -->
<props>
<prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
<prop key="*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>

<!-- 定义BeanNameAutoProxyCreator -->
<bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
<!-- 指定对满足哪些bean name的bean自动生成业务代理 -->
<property name="beanNames">
<!-- 下面是所有需要自动创建事务代理的bean -->
<list>
<value>userService</value>
<value>baseService</value>
<value>shujiService</value>
<value>shujibaseService</value>
</list>
<!-- 此处可增加其他需要自动创建事务代理的bean -->
</property>
<!-- 下面定义BeanNameAutoProxyCreator所需的事务拦截器 -->
<property name="interceptorNames">
<list>
<!-- 此处可增加其他新的Interceptor -->
<value>transactionInterceptor</value>
</list>
</property>
</bean>
<!-- 事物管理 -->
这是tomcat启动报错：
- <Context initialization failed>
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager' defined in class path resource [conf/applicationContext.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'sessionFactory' of bean class [org.springframework.transaction.interceptor.TransactionInterceptor]: Bean property 'sessionFactory' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?
