spring AOP 拦截器方式配置事务失效

Question

Spring.xml配置如下

    <!-- 自动扫描dao和service包(自动注入) -->
    <context:component-scan base-package="com.zfy.db.dao,com.zfy.service" />

spring-mybatis.xml配置文件如下

项目架构
DAO接口： com.zfy.db.dao.form.FormSubjectMapper

package com.zfy.db.dao.form;

import com.zfy.db.model.form.FormSubject;

public interface FormSubjectMapper {


    int insert(FormSubject record);
 }

Service ： com.zfy.service.form.FormSubjectService

package com.zfy.service.form;

import com.zfy.db.model.form.FormSubject;

/**
 * @author keke
 * @version 创建时间：2013-5-15 下午11:05:45
 * 
 */
public interface FormSubjectService {
    public    int insert(FormSubject record) throws Exception;
}

ServiceImpl： com.zfy.service.form.impl.FormSubjectServiceImpl
package com.zfy.service.form.impl;
import com.zfy.db.model.form.FormSubject;

public int insert(FormSubject record){
        FormSubject fs = new FormSubject();
              fs.setFormCode(3);
              fs.setFormName("张三123");
             for (int i = 0; i <2; i++) {
                          mapper.insert(fs);
                     }
     return 0;
}

}

mybatis 配置文件 FormSubjectMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.zfy.db.dao.form.FormSubjectMapper" >
  <resultMap id="BaseResultMap" type="com.zfy.db.model.form.FormSubject" >
    <id column="FORM_CODE" property="formCode" jdbcType="INTEGER" />
    <result column="FORM_NAME" property="formNam" jdbcType="VARCHAR" />
  </resultMap>

  <insert id="insert" parameterType="com.zfy.db.model.form.FormSubject" >
    insert into FORM_SUBJECT (FORM_CODE, FORM_NAME)
    values (#{formCode,jdbcType=INTEGER}, #{formName,jdbcType=VARCHAR})
  </insert>
  </mapper>

Junit 测试类：

@Test
    public void  test1() throws Exception{

        try {

              formSubjectService.insert( null);
        }} catch (RuntimeException e) {
            e.printStackTrace();
        }
    }

开发路线: Spring3.1 mybatis 3.1 运行之后。“张三”是插入进去了，但“李四 ”存在 违反唯一约束条件，没有回滚，所以事务没有起到作用。请大家帮忙看看。谢谢啦！ 在线等……

这些配置文件都是用来配置Spring框架的，在这里你可以定义项目中所使用的bean，以及定义bean之间的依赖关系。

---

在Spring.xml文件中，你使用了context:component-scan标签来自动扫描并注册项目中的bean。在这里，你指定了要扫描的包路径为com.zfy.db.dao和com.zfy.service，Spring框架会在这两个包中寻找带有特定注解（例如@Component，@Service等）的类，并自动将这些类作为bean注册到Spring容器中。

---

在spring-mybatis.xml文件中，你使用了标签来定义了一个数据源bean（即DruidDataSource类型的bean），这个bean将会用于连接数据库。你还使用了标签来定义了一个SqlSessionFactory类型的bean，这个bean将会用于创建SqlSession对象，而SqlSession对象可以用于执行SQL语句。

---

此外，你还使用了标签来定义了一些Mapper接口的代理实现类，这些代理实现类将会用于执行数据库操作。你还使用了tx:annotation-driven标签来启用注解式事务管理，这样你就可以在代码中使用@Transactional注解来声明事务边界。
