MyBatis SpringMVC整合实现步骤详解

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 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 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 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 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。
