NullPointerException異常，我會嘗試使用JTA與Hibernate配置我和春天有這個春天的xml文件：從Spring的LocalSessionFactoryBuilder
model.xml
<beans>
<bean id="txManager"
class="org.springframework.transaction.jta.JtaTransactionManager">
<property name="transactionManagerName" value="java:/TransactionManager" />
<property name="userTransactionName" value="UserTransaction" />
<property name="allowCustomIsolationLevels" value="true" />
</bean>
<tx:annotation-driven transaction-manager="txManager" />
<jee:jndi-lookup id="dataSource" jndi-name="java:jdbc/tSDS" />
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="mappingResources">
<list>
<value>it/thera/common/dto/persistence/Calciatori.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<value>
hibernate.dialect=org.hibernate.dialect.MySQLDialect
hibernate.transaction.factory_class=org.hibernate.transaction.JTATransactionFactory
hibernate.transaction.manager_lookup_class=org.hibernate.transaction.JBossTransactionManagerLookup
hibernate.show_sql=false
</value>
</property>
</bean>
</beans>
...但是這將引發異常：
