SpringMVC(二)
今天在完成的工作的前提下,最终在睡觉前将SpringMVC和Mybatis整合了~~~
其实就是按照从网上(参考http://www.toutiao.com/a6332703083554324737/)找到的教程自己做了一回,我的习惯是先做然后再深究:
1、创建工程(marven工程);
2、创建所需要的目录(如图):
3、各个文件所需要的代码如下:
(1)spring-dao.xml
<?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
http://www.springframework.org/schema/context/spring-context.xsd">
<!-- 配置整合mybatis过程 -->
<!-- 1.配置数据库相关参数properties的属性:${url} -->
<!-- 使用数据库配置文件解耦 -->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!-- 下面的druid配置都是基本配置,具体优化设置可以上网查询,也可以去github上面直接搜索druid -->
<!-- 2.数据库连接池 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
init-method="init" destroy-method="close">
<!-- 配置连接池属性 -->
<property name="driverClassName" value="${jdbc.driver}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
<!-- 配置初始化大小、最小、最大 -->
<property name="initialSize" value="1" />
<property name="minIdle" value="1" />
<property name="maxActive" value="10" />
<!-- 配置获取连接等待超时的时间 -->
<property name="maxWait" value="10000" />
<!-- 配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位是毫秒 -->
<property name="timeBetweenEvictionRunsMillis" value="60000" />
<!-- 配置一个连接在池中最小生存的时间,单位是毫秒 -->
<property name="minEvictableIdleTimeMillis" value="300000" />
<property name="testWhileIdle" value="true" />
<!-- 这里建议配置为TRUE,防止取到的连接不可用 -->
<property name="testOnBorrow" value="true" />
<property name="testOnReturn" value="false" />
<!-- 打开PSCache,并且指定每个连接上PSCache的大小 -->
<property name="poolPreparedStatements" value="true" />
<property name="maxPoolPreparedStatementPerConnectionSize"
value="20" />
<!-- 这里配置提交方式,默认就是TRUE,可以不用配置 -->
<property name="defaultAutoCommit" value="true" />
<!-- 验证连接有效与否的SQL,不同的数据配置不同 -->
<property name="validationQuery" value="select 1 " />
<property name="filters" value="stat" />
<property name="proxyFilters">
<list>
<ref bean="logFilter" />
</list>
</property>
</bean>
<!-- 3.配置SqlSessionFactory对象 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 注入数据库连接池 -->
<property name="dataSource" ref="dataSource"/>
<!-- 配置MyBaties全局配置文件:mybatis-config.xml -->
<property name="configLocation" value="classpath:mybatis-config.xml"/>
<!-- 扫描entity包 使用别名 -->
<!-- cn.acheng1314是我的应用程序的包名,你们需要使用你们自己的包名,也就是前面我们提到过的GroupId -->
<property name="typeAliasesPackage" value="cn.acheng1314.domain"/>
<!-- 扫描sql配置文件:mapper需要的xml文件 -->
<property name="mapperLocations" value="classpath:mapper/*.xml"/>
</bean>
<!-- 4.配置扫描Dao接口包,动态实现Dao接口,注入到spring容器中 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 注入sqlSessionFactory -->
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
<!-- 给出需要扫描Dao接口包 -->
<property name="basePackage" value="cn.acheng1314.dao"/>
</bean>
<!-- 上面的druid的配置 -->
<bean id="logFilter" class="com.alibaba.druid.filter.logging.Slf4jLogFilter">
<property name="statementExecutableSqlLogEnable" value="false" />
</bean>
</beans>

<!-- 配置事务管理器 -->

4、这些只是我能够跑起来的一些程序代码,因为我看到了数据库的cmd窗口运行起来了,具体的实现还没有做,等明天做完了截图。
5、还有其中的一些原理现在也不是很清楚,还需要继续研究一下,等知道了再上图解释介绍。
