使用自动有线Bean和较少的XML配置来重建项目，所以我正在重新研究此问题。我遵循了我以前的项目实现此方法的方式，但是没有用。有人可以为我提供帮助，为什么我应该做出什么改变？

我故意在插入用户详细信息方法中使用不存在的表名来故意引发异常。但是，不会回滚插入用户和插入用户角色的语句。请帮忙。

我当前的注册设计是这样的。

Part of servlet.xml:

<context:component-scan base-package="com.doyleisgod.golfer.controllers"/>
<context:component-scan base-package="com.doyleisgod.golfer.dao"/>
<context:component-scan base-package="com.doyleisgod.golfer.services"/>
<context:component-scan base-package="com.doyleisgod.golfer.validators"/>

Part of application context:

<context:annotation-config />
<tx:annotation-driven />    

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${jdbc.driverClassName}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</bean>

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

Registration controller:

package com.doyleisgod.golfer.controllers;

        if (bindingResult.hasErrors()) {
            logger.warn("Registration Validation Failed");
            model.addAttribute("validationError", "Please correct the fields marked with errors");
            return "registration";
        }

        try {
            iRegistrationService.registerUser(registrationForm);
        } catch (Exception e) {
            logger.error("An Exception has occured processing the registration form");
            model.addAttribute("exceptionError", "An exception has occured, please try again.");
            e.printStackTrace();
            return "registration";
        }

        return "redirect:login.htm?registration=sucessful";
