I’ve added the following to my pom.xml…

<dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
            <version>${org.springframework-version}</version>
        </dependency>

<org.springframework-version>3.1.0.RELEASE</org.springframework-version>

Does anyone have any ideas?

You are missing reference to DataSoure.

your entire xml file should look like this:

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
  <property name="driverClassName" value="com.mysql.jdbc.Driver" />
  <property name="url" value="jdbc:mysql://localhost:3306/xxx" />
  <property name="username" value="xxx" />
  <property name="password" value="xxx" />
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="hibernateProperties">
 <props>
    <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> 
    <prop key="hibernate.show_sql">true</prop> 
    <prop key="hibernate.hbm2ddl.auto">update</prop> 
    <prop key="hibernate.show_sql">true</prop> 
  </props>
     </property>
        <property name="annotatedClasses">
      <list>
        <value>x.y.z.Student</value>        
         </list>
    </property>
  </bean>

<bean id="transactionManager" 
            class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"/>
  </bean>
