原因：
Switch this to "false" to let the transaction originator make the rollback decision. If a participating transaction fails with an exception, the caller can still decide to continue with a different path within the transaction. However, note that this will only work as long as all participating resources are capable of continuing towards a transaction commit even after a data access failure: This is generally not the case for a Hibernate Session, for example; neither is it for a sequence of JDBC insert/update/delete operations.
大意是：如果isGlobalRollbackOnParticipationFailure为false,则会让主事务决定回滚，如果当遇到exception加入事务失败时，调用者能继续在事务内决定是回滚还是继续。然而，要注意是那样做仅仅适用于在数据访问失败的情况下且只要所有操作事务能提交。
初步解决方案：
<bean id="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> <property name="globalRollbackOnParticipationFailure" value="false" /> <!--指定此参数为false--> </bean>
