第Java開發(fā)之ssm三大框架整合目錄1.springmvc2.spring-dao.xml與mybatis-config.xml3.spring-service.xml4.引用

1.springmvc

和只有spring-mvc時(shí)一樣，web.xmlspring-mvc.xml

2.spring-dao.xml與mybatis-config.xml

主要就是spring整合mybatis

spring整合mybatis

在上面的基礎(chǔ)上，去掉成接口的實(shí)現(xiàn)類了，需要配置dao接口掃描包，我的理解是這個(gè)dao接口掃描包中有datasource，有mapper的掃描范圍,它會(huì)自動(dòng)生成這些接口對應(yīng)的mapper,并將接口的mapper放到xml文件中，所以在spring-service中，直接

propertyname=bookmapperref=bookmapper/property

引用即可

xmlversion="1.0"encoding="UTF-8"

beansxmlns="/schema/beans"

xmlns:xsi="/2001/XMLSchema-instance"

xmlns:context="/schema/context"

xsi:schemaLocation="/schema/beans

/schema/beans/spring-beans.xsd

/schema/context

/schema/context/spring-context.xsd"

!--讀取數(shù)據(jù)庫配置文件--

beanid="dataSource"

propertyname="driverClass"value="${jdbc.driver}"/

propertyname="jdbcUrl"value="${jdbc.url}"/

propertyname="user"value="${jdbc.username}"/

propertyname="password"value="${jdbc.password}"/

propertyname="maxPoolSize"value="30"/

propertyname="minPoolSize"value="10"/

!--關(guān)閉連接后不自動(dòng)commit--

propertyname="autoCommitOnClose"value="false"/

!--獲取連接超時(shí)時(shí)間--

propertyname="checkoutTimeout"value="10000"/

!--當(dāng)獲取連接失敗重試次數(shù)--

propertyname="acquireRetryAttempts"value="2"/

/bean

beanid="sqlsessionFactory"

propertyname="dataSource"ref="dataSource"/property

propertyname="configLocation"value="classpath:mybatis-config.xml"/property

/bean

!--配置dao接口掃描包，動(dòng)態(tài)的實(shí)現(xiàn)了dao接口可以注入到spring容器中

就是用來代替BookMapperImpl類--

bean

!--注入sqlsessionfactory--

!--個(gè)人理解,這個(gè)dao接口掃描包中有datasource，有mapper的掃描范圍,

它會(huì)自動(dòng)生成這些接口對應(yīng)的mapper,并將接口的mapper放到xml文件中，所以在spring-service中，直接

propertyname="bookmapper"ref="bookmapper"/property引用即可--

propertyname="sqlSessionFactoryBeanName"value="sqlsessionFactory"/property

!--要掃描的dao包,會(huì)自動(dòng)生成包下的類的接口的實(shí)現(xiàn)類--

propertyname="basePackage"value="com.hxut.rj1192.zyk"/property

/bean

/beans

mybatis-config.xml詳細(xì)在上面的mybatis整合spring的文章中，它做兩件事，配置映射文件路徑，配置接口掃描范圍，它被import到spring-dao.xml中。

xmlversion="1.0"encoding="UTF-8"

!DOCTYPEconfiguration

"/dtd/mybatis-3-config.dtd"

configuration

!--配置數(shù)據(jù)源交給spring了--

!--給類起別名--

typeAliases

packagename="com.hxut.rj1192.zyk.mapper"/

/typeAliases

!--設(shè)置映射文件路徑--

mappers

mapperresource="com/hxut/rj1192/zyk/mapper/Bookmapper.xml"/mapper

/mappers

/configuration

3.spring-service.xml

在這個(gè)文件中要進(jìn)行事務(wù)的處理（事務(wù)本來就應(yīng)該是在service層），要將service層的類全部放到ioc容器中，然后這些類中因?yàn)檎{(diào)用了dao層的類，然后因?yàn)閯偛诺诙颗渲昧私涌趻呙璋?，直接ref獲取mapper即可
