1. ibatis3.*版本以后正式改名为mybaits,它也从apache转到了google code下;也就是说ibatis2.*,mybatis3.*。
2. 映射文件的不同
ibatis的配置文件如下
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE sqlMapConfig PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-config-2.dtd"> <sqlMapConfig> <!-- 公共配置 --> <settings useStatementNamespaces="true" maxRequests="3000" maxSessions="1000" maxTransactions="3000" /> <!-- 配置文件 begin --> <sqlMap resource="com/test/biz/dao/sql/AA_SqlMap.xml" />
<pre name="code" class="html"> <sqlMap resource="com/test/biz/dao/sql/BB_SqlMap.xml" />
</sqlMapConfig>
mybatis的配置文件如下
<?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> <settings> <!-- changes from the defaults for testing --> <setting name="cacheEnabled" value="false" /> <setting name="useGeneratedKeys" value="true" /> <setting name="defaultExecutorType" value="REUSE" /> <!-- 延迟加载 --> <setting name="lazyLoadingEnabled" value="true" /> <setting name="aggressiveLazyLoading" value="false" /> </settings> <mappers> <mapper resource="com/test/biz/dao/sql/AAMapper.xml"/> </mappers> </configuration>
从以上两个配置文件,大致分析有哪些不同点:
2.1 dtd约束文件不同
2.2 ibatis中根元素是sqlMapConfig,mybatis中是configuration;
2.3 settings属性的不同配置
ibatis中是
<settings 属性1="属性值1" 属性2="属性值2" 属性x="属性值x"/>
mybatis中是
<settings>
<setting name="属性1" value="属性值1"/>
<setting name="属性2" value="属性值2"/>
<setting name="属性x" value="属性值x"/>
</settings>
2.4 ibatis中是使用sqlMap元素,mybatis中是使用mappers元素;
2.5 数据库表的映射区别
ibatis中某表的映射文件
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-2.dtd" > <sqlMap namespace="PP_CLASS_PROPERTY">

两者的区别有:
2.5.1 ibatis中根元素是sqlMap,mybatis中是mapper;
2.5.2 在 iBatis 中,namespace 不是必需的,且它的存在没有实际的意义。在 MyBatis 中,namespace 终于派上用场了,它使得映射文件与接口绑定变得非常自然。
2.5.3 ibatis中有resultMap和resultClass两种返回类型,resultMap是我们在ibatis的配置文件中定义的,也就是在配置文件中使用resultMap元素定义的;resultClass是指java语言中内置的类型,如:integer、java.util.HashMap等等;
mybatis中将两者统一为resultType,这样挺好的,开发者不用再记两个属性了。
2.5.4 ibatis中有parameterClass,mybatis中有parameterType,两者区别不大。
2.5.5 参数的写法比较
ibatis中写法,如代码片段:
WHERE ID = #id:VARCHAR#
mybatis中写法,如代码片段:
where ID = #{id,jdbcType=VARCHAR}
2.5.6 iBatis/MyBatis 调用存储过程的写法
iBatis 调用存储过程的方法,通过使用 <procedure> 元素进行存储过程的调用:
<parameterMap id="swapParameters" class="map" > <parameter property="contactId" jdbcType="INTEGER" javaType="java.lang.Integer" mode="IN"/> <parameter property="firstName" jdbcType="VARCHAR" javaType="java.lang.String" mode="IN"/> <parameter property="lastName" jdbcType="VARCHAR" javaType="java.lang.String" mode="IN"/> </parameterMap> <procedure id="swapContactName" parameterMap="swapParameters" > {call swap_contact_name (?, ?,?)} </procedure>
在 MyBatis 中,<proccedure> 元素已经被移除,通过 <select>、<insert> 和 <update> 进行定义:
<select id="swapContactName" parameterMap="swapParameters" statementType="CALLABLE"> { ? = call swap_contact_name (?,?,?)} </select>
如上所示,通过 statementType 属性将该语句标识为存储过程而非普通 SQL 语句。
2.6 ibatis和mybatis与spring的集成配置
ibatis的配置
<!--===================================================================== --> <!-- iBATIS 配置文件定义 --> <!--===================================================================== --> <bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean"> <property name="configLocation" value="classpath:sqlMap-config.xml" /> <property name="dataSource" ref="dataSource" /> </bean>
mybatis的配置
<!-- define the MyBatis SqlSessionFactory --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="configLocation" value="classpath:com/ilvyou/core/config/mybatis-config.xml" /> <property name="mapperLocations" value="classpath*:com/ilvyou/**/*Mapper.xml" /> </bean>
通过前面的示例可以看出,MyBatis 在编码中的最大的改变就是将一个最常用的 API 由 SqlMapClient 改为了 SqlSessionFactory。另外,类型处理器接口也由原来的 TypeHandlerCallback 改为了 TypeHandler。最后 DataSourceFactory 也进行了调整,移动到 org.apache.ibatis.datasource 包下,其中的方法也作了微调。总之,代码层面公开的部分改动较少,不会给开发者造成较大的移植成本。
