一、需要导入的jar包
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>4.3.11.RELEASE</version>
</dependency>
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis</artifactId>
<version>3.3.1</version>
</dependency>
<dependency>
<groupId>org.mybatis</groupId>
<artifactId>mybatis-spring</artifactId>
<version>1.2.3</version>
</dependency>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid</artifactId>
<version>1.0.18</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.14</version>
</dependency>
二、数据库的设置和 SqlSession Bean
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:database.properties</value>
</list>
</property>
</bean>
<!--BI 商品推荐数据源-->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
<property name="driverClassName" value="${jdbc.driver}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
<!--链接池初始化线程数据-->
<property name="initialSize" value="${jdbc.initialPoolSize}" />
<!--链接池最小线程数-->
<property name="minIdle" value="${jdbc.minPoolSize}" />
<!--链接池最大线程数-->
<property name="maxActive" value="${jdbc.maxPoolSize}" />
<!--获取链接超时时间-->
<property name="maxWait" value="${jdbc.maxWaitTime}" />
<!--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" />
<!--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="validationQuery" value="SELECT 'x'" />
<property name="testWhileIdle" value="true" />
<property name="testOnBorrow" value="false" />
<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="false" />
<property name="maxPoolPreparedStatementPerConnectionSize" value="20" />
</bean>
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!--mybatis的配置文件-->
<property name="configLocation" value="classpath:mybatis-config.xml" />
<property name="dataSource" ref="dataSource" />
</bean>
<bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg index="0" ref="sqlSessionFactory" />
</bean>
三、mybatis配置文件
<configuration>
<mappers>
<mapper resource="supplierProductMapper.xml"/>
</mappers>
</configuration>
四、实体类
public class SupplierProduct {
private int id;
private int supplierId;
private String createdAt;
private String updatedAt;
private String deletedAt;
private int isDeleted;
//省略get、set方法
五、实体类与mybatis的映射
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.jolly.spider.bean.supplierProductMapper" >
<!--返回自增的id-->
<insert id="insert" useGeneratedKeys="true" keyProperty="id" parameterType="com.jolly.spider.bean.SupplierProduct">
INSERT INTO
supplier_product
(
supplier_id,created_at,updated_at,process_status,is_deleted,supp_parent_id,supp_parent_code,
name,
description,category,image_url,image_list,extra,currency
)VALUES(
#{supplierId},#{createdAt},#{updatedAt},#{processStatus},#{isDeleted},#{suppParentId},#{suppParentCode},#{name},
#{description},#{category},#{imageUrl},#{imageList},#{extra},#{currency}
)
</insert>
</mapper>
六、测试
private final static String SPACE="com.jolly.spider.bean.supplierProductMapper";
private static String path="database.config.xml";
private SqlSessionTemplate sqlSession;
public SupplierDao(){
ApplicationContext context=new ClassPathXmlApplicationContext(path);
sqlSession=(SqlSessionTemplate) context.getBean("sqlSession");
}
public int insert(SupplierProduct sp){
try{
return sqlSession.insert(SPACE+".insert",sp);
}catch (Exception e){
e.printStackTrace();
}
return -1;
}
