背景:
基于mybatis的3.1.1和Spring的3.1.0.RELEASE做集成操作,不采用事务控制。
依赖jar:
<dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.1.1</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.1.1</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.25</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>3.1.0.RELEASE</version> </dependency>
web.xml中感知到spring的存在:
<context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring-*.xml</param-value> </context-param>
spring-db.xml:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:task="http://www.springframework.org/schema/task" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:beans="http://www.springframework.org/schema/beans" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-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/task http://www.springframework.org/schema/task/spring-task-3.1.xsd"> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://host:3005/db" /> <property name="username" value="username" /> <property name="password" value="password" /> </bean> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="configLocation" value="/WEB-INF/mybatis-config.xml"/> <property name="mapperLocations" value="classpath*:com/xx/dao/*.xml" /> <property name="typeAliasesPackage" value="com.xx.vo" /> </bean> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.xx.dao" /> </bean> </beans>
上述指定了dataSource,同时sqlSessionFactory中引入了dataSource,configLocation中的配置如下:
<?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> <typeAliases> <typeAlias alias="demo_t" type="com.xx.vo.Demo" /> </typeAliases> </configuration>
mapperLocations(DemoMapper.xml)配置如下:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.xx.dao.DemoDao"> <cache /> <select id="getDemo" parameterType="string" resultType="Demo" > select id from demo_t where id = #{id} </select> </mapper>
VO和Dao如下:
public class Demo implements Serializable { private static final long serialVersionUID = -7271550743849359837L; private String id; public String getId() { return id; } public void setId(String id) { this.id = id; } }
public interface DemoDao { Demo getDemo(String id); }
此时配置完成只需要调用即可:
this.demoDao.getDemo(id);
