为什么spring的事务处理不起作用?

在CustomerServiceImp类的add()方法里先给customers表里插入一条数据,然后在往Customerdaily表里插入一条数据,由于在Customerdaily.hbm.xml里配置的主键生成是根据customers的主键生成,两张表共用相同的主键,由于customerdaily表的Name属性定义为NOU NULL,在add()方法里没有给CustomerDaily对象的Name属性赋值,这样数据库肯定会抛异常,正常的话,customers和Customerdaily里都不会插入记录,但是程序完执行的时候,customers表里有一条记录,CustomerServiceImp类其实是TransactionProxyFactoryBean类,也就是CustomerServiceImp的代理,但是我用System.out.println(customerService.getClass().getName());语句输出的结果却还是com.ajax.service.CustomerServiceImp,为什么spring的事务在这里没有起作用呢?

customerService类的定义如下,在add()方上加入事务处理,:

package com.ajax.service;

import java.util.List;

import com.ajax.dao.CustomerDailyDao;
import com.ajax.dao.CustomerDao;
import com.ajax.pojos.Customer;
import com.ajax.pojos.Customerdaily;

public class CustomerServiceImp implements CustomerService{
 private CustomerDao customerDao;
 private CustomerDailyDao customerDailyDao;
 public void add(Customer customer) throws Exception {
  // TODO Auto-generated method stub
  Customerdaily customerDaily=new Customerdaily();
//  customerDaily.setName(customer.getName());//注释
  customer.setCustomerDaily(customerDaily);
  customerDaily.setCustomer(customer);
  customerDao.addCustomer(customer);
 }

 }

数据库表的DDL是这样定义:

    create table `ajax`.`customers`(
        `id` int not null auto_increment,
       `name` varchar(20) default '' not null unique,
       `dataofbirthday` date default '' not null,
       `sex` varchar(1) default '' not null,
       `address` varchar(40) default '' not null,
       `amount_water` double,
       `amount_elic` double,
       `updatedate` varchar(20) default '' not null,
       `remark` varchar(100),
        primary key (`id`)
    );

    create table `ajax`.`customerdaily`(
        `id` int not null auto_increment,
       `name` varchar(20) default '' not null unique,
       `usedwaterinmonth` double,
       `usedelicinmonth` double,
       `managecharge` double,
        primary key (`id`)
    );

    alter table `ajax`.`customerdaily` 
        add index `customerdaily_ibfk_1`(`id`),
        add constraint `customerdaily_ibfk_1`
        foreign key (`id`)
        references `ajax`.`customers`(`id`);
    create index `PRIMARY` on `ajax`.`customerdaily`(`id`);
    create index `name` on `ajax`.`customerdaily`(`name`);

    customers表的hibernate的配置如下:

 <?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

Customerdaily表的hibernate的配置如下:

<?xml version="1.0" encoding="utf-8"?>

            </generator>
        </id>
        <one-to-one name="customer" class="com.ajax.pojos.Customer" constrained="true"/>
        <property name="name" type="java.lang.String">

            <column name="managecharge" precision="22" scale="0" />
        </property>
    </class>
</hibernate-mapping>
