mybatis_基本配置

基于maven 管理的工程

1..加入以下jar包

<dependency><groupId>org.mybatis</groupId><artifactId>mybatis</artifactId></dependency><dependency><groupId>org.mybatis</groupId><artifactId>mybatis-spring</artifactId></dependency>

2.导入数据库连接jar包<pre name="code" class="html"><dependency><span style="white-space:pre"></span><groupId>mysql</groupId><span style="white-space:pre"></span><artifactId>mysql-connector-java</artifactId></dependency>

3.配置文件mybatis.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:p="http://www.springframework.org/schema/p"      xmlns:context="http://www.springframework.org/schema/context"      xmlns:mvc="http://www.springframework.org/schema/mvc"     xsi:schemaLocation=" http://www.springframework.org/schema/beans                            http://www.springframework.org/schema/beans/spring-beans-3.1.xsd                           http://www.springframework.org/schema/context                           http://www.springframework.org/schema/context/spring-context-3.1.xsd                           http://www.springframework.org/schema/mvc                           http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">     <!-- 自动扫描 -->     <context:component-scan base-package= "项目的包名" />     <!-- 引入配置文件 -->     <bean id="propertyConfigurer"         class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" >         <property name= "location" value="数据库配置文件所在路径" />     </bean >  <!--数据库配置-->    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"          destroy-method="close" >         <property name= "driverClassName" value="${driver}" />         <property name= "url" value ="${url}" />         <property name= "username" value ="${username}" />         <property name= "password" value ="${password}" />         <!-- 初始化连接大小 -->          <property name= "initialSize" value="${initialSize}" ></property>          <!-- 连接池最大数量 -->          <property name= "maxActive" value="${maxActive}" ></property>          <!-- 连接池最大空闲 -->          <property name= "maxIdle" value="${maxIdle}" ></property>          <!-- 连接池最小空闲 -->          <property name= "minIdle" value="${minIdle}" ></property>          <!-- 获取连接最大等待时间 -->     <property name="maxWait" value="${maxWait}"></property>      </bean >      <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean" >         <property name= "dataSource" ref ="dataSource" />         <!-- 自动扫描mapping.xml文件 -->          <property name= "mapperLocations" value="mapper.xml文件存放路径" ></property>      </bean >      <!-- DAO接口所在包名，Spring会自动查找其下的类 -->      <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" >         <property name= "basePackage" value="dao层接口所在位置" />         <property name= "sqlSessionFactoryBeanName" value="sqlSessionFactory" ></property>   </bean></beans>  

4.将mybatis.xml配置文件配置到web.xml中即可

至此：mybatis的基本配置就完成了
