1、添加spring相关jar包
2、配置ehcache jar包。
3、添加ehcache mybatis 适配器jar包（在mybatis官网）
4、添加spring mybatis 适配器jar包（在mybatis）官网
5、pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.ntjr.mybatisSpring</groupId> <artifactId>mybatisSpring</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <properties> <mybatis_version>3.4.2</mybatis_version> <mysql_connector_version>5.1.38</mysql_connector_version> <org.springframework>4.3.7.RELEASE</org.springframework> </properties> <dependencies> <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis_version}</version> </dependency> <!-- https://mvnrepository.com/artifact/mysql/mysql-connector-java --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql_connector_version}</version> </dependency> <!-- https://mvnrepository.com/artifact/log4j/log4j --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.16</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework/spring-webmvc --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${org.springframework}</version> </dependency> <!-- https://mvnrepository.com/artifact/org.springframework/spring-tx --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${org.springframework}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${org.springframework}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${org.springframework}</version> </dependency> <!-- https://mvnrepository.com/artifact/org.aopalliance/com.springsource.org.aopalliance --> <dependency> <groupId>org.aopalliance</groupId> <artifactId>com.springsource.org.aopalliance</artifactId> <version>1.0.0</version> </dependency> <!-- https://mvnrepository.com/artifact/net.sourceforge.cglib/com.springsource.net.sf.cglib --> <dependency> <groupId>net.sourceforge.cglib</groupId> <artifactId>com.springsource.net.sf.cglib</artifactId> <version>2.2.0</version> </dependency> <!-- https://mvnrepository.com/artifact/org.aspectj/com.springsource.org.aspectj.weaver --> <dependency> <groupId>org.aspectj</groupId> <artifactId>com.springsource.org.aspectj.weaver</artifactId> <version>1.6.10.RELEASE</version> </dependency> <!-- https://mvnrepository.com/artifact/com.mchange/c3p0 --> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.5.2</version> </dependency> <dependency> <groupId>org.mybatis.caches</groupId> <artifactId>mybatis-ehcache</artifactId> <version>1.1.0</version> </dependency> <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis-spring --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.1</version> </dependency> <!-- https://mvnrepository.com/artifact/commons-logging/commons-logging --> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.2</version> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.taglibs/taglibs-standard-impl --> <dependency> <groupId>org.apache.taglibs</groupId> <artifactId>taglibs-standard-impl</artifactId> <version>1.2.5</version> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.taglibs/taglibs-standard-impl --> <dependency> <groupId>org.apache.taglibs</groupId> <artifactId>taglibs-standard-spec</artifactId> <version>1.2.5</version> </dependency> </dependencies> </project>
6、applicationContext.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" xmlns:mybatis-spring="http://mybatis.org/schema/mybatis-spring" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring-1.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd"> <!-- Spring希望管理所有的业务逻辑组件，等。。。 --> <context:component-scan base-package="com.atguigu.mybatis"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" /> </context:component-scan> <!-- 引入数据库的配置文件 --> <context:property-placeholder location="classpath:dbconfig.properties" /> <!-- Spring用来控制业务逻辑。数据源、事务控制、aop --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="jdbcUrl" value="${jdbc.url}"></property> <property name="driverClass" value="${jdbc.driver}"></property> <property name="user" value="${jdbc.username}"></property> <property name="password" value="${jdbc.password}"></property> </bean> <!-- spring事务管理 --> <bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean> <!-- 开启基于注解的事务 --> <tx:annotation-driven transaction-manager="dataSourceTransactionManager"/> <!-- 整合mybatis 目的：1、spring管理所有组件。mapper的实现类。 service==>Dao @Autowired:自动注入mapper； 2、spring用来管理事务，spring声明式事务 --> <!--创建出SqlSessionFactory对象 --> <bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"></property> <!-- configLocation指定全局配置文件的位置 --> <property name="configLocation" value="classpath:mybatis-config.xml"></property> <!--mapperLocations: 指定mapper文件的位置--> <property name="mapperLocations" value="classpath:mybatis/mapper/*.xml"></property> </bean> <!--配置一个可以进行批量执行的sqlSession --> <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate"> <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactoryBean"></constructor-arg> <constructor-arg name="executorType" value="BATCH"></constructor-arg> </bean> <!-- 扫描所有的mapper接口的实现，让这些mapper能够自动注入； base-package：指定mapper接口的包名 --> <mybatis-spring:scan base-package="com.atguigu.mybatis.dao"/> <!-- <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.atguigu.mybatis.dao"></property> </bean> --> </beans>
7、mybatis-config.xml
<?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> <settings> <setting name="mapUnderscoreToCamelCase" value="true" /> <setting name="jdbcTypeForNull" value="NULL" /> <!--显式的指定每个我们需要更改的配置的值，即使他是默认的。防止版本更新带来的问题 --> <setting name="cacheEnabled" value="true" /> <setting name="lazyLoadingEnabled" value="true" /> <setting name="aggressiveLazyLoading" value="false" /> </settings> <databaseIdProvider type="DB_VENDOR"> <property name="MySQL" value="mysql" /> <property name="Oracle" value="oracle" /> <property name="SQL Server" value="sqlserver" /> </databaseIdProvider> </configuration>
注意：此处mybatis配置文件中没有配置数据源，数据源由spring负责。
此外还需要ehcache.xml配置文件,Mapper.xml文件。
