1.springmvc
和只有spring-mvc时一样，web.xml spring-mvc.xml
spring-mvc.xml

</filter-mapping>
</web-app>2.spring-dao.xml与mybatis-config.xml
主要就是spring整合mybatis
spring整合mybatis
在上面的基础上，去掉成接口的实现类了，需要配置dao接口扫描包，我的理解是这个dao接口扫描包中有datasource，有mapper的扫描范围, 它会自动生成这些接口对应的mapper,并将接口的mapper放到xml文件中，所以在spring-service中，直接
<property name="bookmapper" ref="bookmapper"></property>
引用即可
<?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.xsd
http://www.springframework.org/schema/context
https://www.springframwork.org/schema/context/spring-context.xsd">
<!-- 读取数据库配置文件-->
<context:property-placeholder location="classpath:database.properties"></context:property-placeholder>
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}"/>
<property name="jdbcUrl" value="${jdbc.url}"/>
<property name="user" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
<property name="maxPoolSize" value="30"/>
<property name="minPoolSize" value="10"/>
<!-- 关闭连接后不自动commit -->
<property name="autoCommitOnClose" value="false"/>
<!-- 获取连接超时时间 -->
<property name="checkoutTimeout" value="10000"/>
<!-- 当获取连接失败重试次数 -->
<property name="acquireRetryAttempts" value="2"/>
</bean>
<bean id="sqlsessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="configLocation" value="classpath:mybatis-config.xml"></property>
</bean>
<!--配置dao接口扫描包 ，动态的实现了dao接口可以注入到spring容器中
就是用来代替BookMapperImpl类 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 注入sqlsessionfactory-->
<!--个人理解,这个dao接口扫描包中有datasource，有mapper的扫描范围,
它会自动生成这些接口对应的mapper,并将接口的mapper放到xml文件中，所以在spring-service中，直接
<property name="bookmapper" ref="bookmapper"></property> 引用即可-->
<property name="sqlSessionFactoryBeanName" value="sqlsessionFactory"></property>
<!-- 要扫描的dao包, 会自动生成包下的类的接口的实现类-->
<property name="basePackage" value="com.hxut.rj1192.zyk"></property>
</bean>
</beans>mybatis-config.xml 详细在上面的mybatis整合spring的文章中，它做两件事，配置映射文件路径，配置接口扫描范围，它被import到 spring-dao.xml中。
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!-- 配置数据源交给spring了-->
<!-- 给类起别名-->
<typeAliases>
<package name="com.hxut.rj1192.zyk.mapper"/>
</typeAliases>
<!-- 设置映射文件路径-->
<mappers>
<mapper resource="com/hxut/rj1192/zyk/mapper/Bookmapper.xml"></mapper>
</mappers>
</configuration>3.spring-service.xml
在这个文件中要进行事务的处理（事务本来就应该是在service层），要将service层的类全部放到ioc容器中，然后这些类中因为调用了dao层的类，然后因为刚才第二部配置了接口扫描包，直接ref获取mapper即可
<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.xsd
http://www.springframework.org/schema/context
https://www.springframwork.org/schema/context/spring-context.xsd">
<!-- 开启注解驱动-->
<context:component-scan base-package="com.hxut.rj1192.zyk.service"></context:component-scan>
<bean id="booksServiceimpl" class="com.hxut.rj1192.zyk.service.BooksServiceimpl">
<property name="bookmapper" ref="bookmapper"></property>
</bean>
<!-- 声明式事务-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<!-- 注入数据源 -->
<property name="dataSource" ref="dataSource"></property>
</bean>
</beans>4.引用
将这些文件的引用放到一个大的xml文件中，这个文件只放引用，这样就很容易看
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<import resource="applicationContext.xml"></import>
<import resource="spring-dao.xml"></import>
<import resource="Spring-Service.xml"></import>
<import resource="Spring-springmvc.xml"></import>
</beans>或者在project structure中设置 spring application context，效果是一样的
