2、在java目录下创建entity、dao、server、controller等主要目录
3、在resource中创建mapper文件夹，用于存放mybatis的mapper.
4、在resource中创建jdbc.properties文件，用于配置数据库连接参数
# jdbc要和依赖中的对应jdbc.driver=org.postgresql.Driverjdbc.url=jdbc:postgresql://127.0.0.1:5432/dm_video_demojdbc.username=postgresqljdbc.password=123456
5、在resource中创建mybatis.<??><!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration> <!-- 配置全局属性 --> <settings> <!-- 使用jdbc的getGeneratedKeys获取数据库自增主键值 --> <setting name="useGeneratedKeys" value="true" /> <!-- 使用列别名替换列名 默认:true --> <setting name="useColumnLabel" value="true" /> <!-- 开启驼峰命名转换:Table{a_bc} -> Entity{aBc} --> <setting name="mapUnderscoreToCamelCase" value="true" /> </settings></configuration>
6、在resource中创建spring_dao.<??><beans ="http://www.springframework.org/schema/beans" ="http://www.w3.org/2001/ ="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans >> <!-- 配置整合mybatis过程 --> <!-- 1.配置数据库相关参数properties的属性：${url} --> <context:property-placeholder location="classpath:jdbc.properties" /> <!-- 2.数据库连接池 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <!-- 配置连接池属性 --> <property name="driverClass" value="${jdbc.driver}" /> <property name="jdbcUrl" value="${jdbc.url}" /> <property name="user" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <!-- c3p0连接池的私有属性 --> <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> <!-- 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" /> <!-- MyBaties配置文件:mybatis.--> <property name="configLocation" value="classpath:mybatis. /> <!-- 扫描entity包 使用别名 --> <property name="typeAliasesPackage" value="com.test.entity" /> <!-- 扫描sql配置文件:mapper需要的--> <property name="mapperLocations" value="classpath:mapper/*. /> </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="com.test.dao" /> </bean></beans>
