最近使用開發(fā)的過程中出現(xiàn)了一個小問題，順便記錄一下原因和方法--配置事務(wù)

????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=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd "><!-- 引入屬性文件 --><context:property-placeholder location="classpath:config.properties" /><!-- 主動掃描dao和service包(主動注入) --><context:component-scan base-package="com.zfy.db.dao,com.zfy.service" /> </beans>

????spring-mybatis.xml配置文件如下

俄國作家契訶夫說：“有大狗，有小狗，小狗不該因為大狗的存在而心慌意亂。所有的狗都應(yīng)該叫，就讓他各自用上帝給他的聲音。

????項目架構(gòu)?

????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 創(chuàng)立時間：2013-5-15 下晝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 創(chuàng)立時間：2013-5-15 下晝11:06:56* */ @Service @Transactional public class FormSubjectServiceImpl implements FormSubjectService {@Resourceprivate 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? 測試類：

?

@Testpublic void test1() throws Exception{try {FormSubject fs = new FormSubject();fs.setFormCode(3);fs.setFormName("張三123");for (int i = 0; i <2; i++) {mapper.insert( fs);}} catch (RuntimeException e) {e.printStackTrace();}}

開發(fā)線路: Spring3.1? mybatis 3.1?

????運行之后。“張三”是插入進去了，但“李四 ”存在 違反獨一約束條件，沒有回滾，所以事務(wù)沒有起到作用。

?

????請大家?guī)椭纯础Ｖx謝啦！ 在線等……
