各位高手帮忙解决一下啊，谢谢了。

实体类：
@Entity
public class Customer implements Serializable{
private static final long serialVersionUID = -803075682525328610L;
private Integer customerId;
private String loginName;
private String password="123456";
private String nickName;
private String email;
private String cellphone;
@Id @GeneratedValue
public Integer getCustomerId() {
return customerId;
}
}
DAO:
public interface DAO<T> {
public void save(Object entity);
}
DAO抽象类：
@Transactional
public abstract class DaoSupport<T> implements DAO<T> {
protected Class<T> entityClass = GenericsUtils.getSuperClassGenricType(this.getClass());
@PersistenceContext protected EntityManager em;
public void save(Object entity) {
em.persist(entity);
}

}

Service层：
public interface CustomerService extends DAO<Customer>{
}

@Service
@Transactional
public class CustomerServiceBean extends DaoSupport<Customer> implements CustomerService {
}

Controller层：
@Controller
public class ModiPersonDataController {
@Resource CustomerService customerService;

@RequestMapping("/modiPersonDataUI.do")
public String jumpToModiUI() {
return "modiPersonData";
}
/**
* 修改个人资料和密码
*/
@RequestMapping("/modiPersonData.do")
public void modiPersonData(CustomerForm customerForm){
Customer customer = new Customer();
customer.setLoginName(customerForm.getLoginName());
customer.setPassword(customerForm.getPassword());
customer.setNickName(customerForm.getNickName());
customer.setCellphone(customerForm.getCellphone());
customer.setEmail(customerForm.getEmail());
customerService.save(customer);
}
}

webform层：
public class CustomerForm implements Serializable{
private static final long serialVersionUID = -4425312158083346598L;
private Integer customerId;
private String loginName;
private String password;
private String nickName;
private String cellphone;
private String email;
public String getLoginName() {
return loginName;
}
。。。
}

persistence.xml 配置如下：

<?xml version="1.0"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0">

<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.format_sql" value="false"/>
</properties>
</persistence-unit>
</persistence>

beans.xml配置如下：
<aop:aspectj-autoproxy/>
<context:component-scan base-package="cn.kuaishang"/>
<context:property-placeholder location="classpath:jdbc.properties"/>

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">

</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory"/>
</bean>

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

jdbc.properties）(略)

spring mvc 配置如下：

<context:component-scan base-package="cn.kuaishang"/>

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"
p:prefix="/WEB-INF/jsp/" p:suffix=".jsp"/>

web.xml 配置如下：
<display-name>Spring Annotation MVC Sample</display-name>

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:beans.xml</param-value>
</context-param>


<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>

<servlet>
<servlet-name>annomvc</servlet-name>
