篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了MyBatis_ibatis和mybatis的区别相关的知识，希望对你有一定的参考价值。
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>
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"/>
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">

</mapper>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。
