最近使用开发的过程中出现了一个小问题,顺便记录一下原因和方法--配置事务
Spring.xml配置如下
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="

<!-- 主动扫描dao和service包(主动注入) -->
<context:component-scan base-package="com.zfy.db.dao,com.zfy.service" />
</beans>
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 创立时间:2013-5-15 下昼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;mport com.zfy.db.model.form.FormSubject;
/**
* @author keke
* @version 创立时间:2013-5-15 下昼11:06:56
*
*/
@Service
@Transactional
public class FormSubjectServiceImpl implements FormSubjectService {
@Resource
private FormSubjectMapper mapper;
public int insert(FormSubject record) throws Exception {
return mapper.insert(record);
}
}
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 {
FormSubject fs = new FormSubject();
fs.setFormCode(3);
fs.setFormName("张三123");
for (int i = 0; i <2; i++) {
mapper.insert( fs);
}} catch (RuntimeException e) {
e.printStackTrace();
}
}
开发线路: Spring3.1 mybatis 3.1
运行之后。“张三”是插入进去了,但“李四 ”存在 违反独一约束条件,没有回滚,所以事务没有起到作用。
请大家帮助看看。谢谢啦! 在线等……
文章结束给大家分享下程序员的一些笑话语录:
看到有人回帖“不顶不是中国人”,他的本意是想让帖子沉了。
