[游一游走一走]

<property name="sessionFactory" value="sessionFactory"></property>
不应该是value="sessionFactory"而是ref="sessionFactory"

[Nodin]

楼主把
<bean id="userDAO" class="com.lr.dao.impl.UserDaoImpl">
<property name="sessionFactory" value="sessionFactory"></property>
</bean>

中的value改为ref

[sustbeckham]

[Quote=引用 2 楼 zyz1985 的回复:]

<property name="sessionFactory" value="sessionFactory"></property>
不应该是value="sessionFactory"而是ref="sessionFactory"
[/Quote]

楼上说的很对


org.springframework.beans.TypeMismatchException: Failed to convert property value of type [java.lang.String] to required type [org.hibernate.SessionFactory] for property 'sessionFactory'
这句已经说的很明白了。

[yukiMark]

<property name="sessionFactory">
			<ref bean="sessionFactory" />
		</property>

这样也行

楼上都说了 自己要学会看异常提示~~

SSH启动报错 原因大致分为两种：
一： 配置文件有问题
二： jar 包的问题（冲突、缺少。。。）
