Apache Tomcat/7.0.67

原因：从No bean named 'transactionManager' is defined看出是事物出了问题，在bean中没有配置事物

解决方案：在spring的配置文件中配置如下信息

 <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
          <property name="dataSource" ref="comboPooledDataSource"></property>
  </bean>

 <tx:annotation-driven transaction-manager="transactionManager"/>
