Answer 1

Failed to convert property value of type [java.lang.String] to required type [javax.sql.DataSource] for property 'dataSource'

这句话就是关键,你定义sessionFactory bean 的时候可能把该用<ref bean = "dataSource">的地方用了<value>dataSource</value>了吧????最好吧你的ApplicationContext.xml贴出来

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="configLocation">
<value>WEB-INF/classes/hibernate.cfg.xml</value>
</property>
<property name="hibernateProperties"
value="hibernate.dialect=org.hibernate.dialect.MySQLDialect" />
</bean>
