Spring MVC JdbcTemplate Transactional Annotation does not work

I have two insert operation in one http post request. something like

@Service
public class StudentService {

    @Transactional(rollbackFor = Exception.class, propagation = Propagation.REQUIRED)
    public int create(final Student student) {
        // insert into table 1

        // insert into table 2 using id return from insert 1, but something BAD happen here
    }
}

so, I added @Transactional at method level as shown above.

In order to make it work, I added this tx:annotation-driven

<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>

so my app-servlet.xml looks like

<?xml version="1.0" encoding="UTF-8"?>
<beans 
    xmlns="http://ift.tt/GArMu6"
    xmlns:mvc="http://ift.tt/1bHqwjR"
    xmlns:tx="http://ift.tt/OGfeU2"
    xmlns:xsi="http://ift.tt/ra1lAU" 
    xmlns:p="http://ift.tt/1jdM0fE"
    xmlns:context="http://ift.tt/GArMu7"
    xsi:schemaLocation="
        http://ift.tt/GArMu6
        http://ift.tt/1cnl1uo
        http://ift.tt/GArMu7 
        http://ift.tt/1ldEMZY
        http://ift.tt/1bHqwjR
        http://ift.tt/1kF4x7W
        http://ift.tt/OGfeU2
        http://ift.tt/KC395X">

    <mvc:annotation-driven />
    <mvc:resources mapping="/res/**" location="/res/" />

    <context:component-scan base-package="com.app" />

    <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

    <bean id="dataSource" name="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://xxx:3306/AppDb" />
        <property name="username" value="username" />
        <property name="password" value="password" />
    </bean>

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

    <tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>
</beans>

the component-scan will basically scan all class include controller, service, model, viewmodel, helper class etc.

If I remove the tx:annotation-driven, the @transactional won't work. But once I add this tx:annotation-driven, some error starts to appear, like

Error creating bean with name 'homeController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.app.service.StudentService com.app.controller.HomeController.studentRepository; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'studentService' defined in file [/path/workspace/.metadata/.plugins/http://ift.tt/1Hzsbw2]: Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/springframework/cglib/transform/impl/MemorySafeUndeclaredThrowableStrategy

How can I make this @transactional work.
