2、错误原因

@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = false)

Java中加了注解，但是在applicationContext.xml未配置事务管理

3、解决办法

在applicationContext.xml中添加事务管理配置

<!-- 事务管理  -->
<bean name="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
	<property name="dataSource" ref="dataSource" />
</bean>
