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">

</hibernate-mapping>

Customerdaily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">

??????? </property>
??????? <property name="usedwaterinmonth" type="java.lang.Double">
??????????? <column name="usedwaterinmonth" precision="22" scale="0" />

??????? <property name="usedelicinmonth" type="java.lang.Double">
??????????? <column name="usedelicinmonth" precision="22" scale="0" />
??????? </property>
??????? <property name="managecharge" type="java.lang.Double">
??????????? <column name="managecharge" precision="22" scale="0" />
??????? </property>
??? </class>
</hibernate-mapping>

spring的配置文件是这样的

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd" >
<beans>
?<import resource="springDao.xml"/>
