預設mybatis需要在配置檔案中載入每個mapper.xml，例如：

<?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>
	<!-- <properties resource="db.properties" /> -->
	<settings>
		<!-- 開啟延遲載入的開關 -->
		<setting name="lazyLoadingEnabled" value="true" />
		<!-- 將積極載入修改為消極載入，即延遲載入 -->
		<setting name="aggressiveLazyLoading" value="false" />
		<!-- 開啟二級快取 -->
		<setting name="cacheEnabled" value="true" />
	</settings>
	<typeAliases>
		<package name="cn.study.mybatis.po" />
	</typeAliases>

	<!-- 和Spring整合後environment配置都會被幹掉 -->
	<environments default="development"> 
		<environment id="development"> 
			<!-- 使用jdbc事務管理，目前由mybatis來管理  -->
			<transactionManager type="JDBC" /> 
			<!--資料庫連線池，目前由mybatis來管理 -->
			<dataSource type="POOLED"> 
			<property name="driver" value="${jdbc.driver}"/> 
			<property name="url" value="${jdbc.url}" /> 
			<property name="username" value="${jdbc.username}"/> 
			<property name="password" value="${jdbc.password}"/> 
			</dataSource> </environment> 
	</environments>
	<mappers>
		<mapper resource="cn/study/mybatis/mapper/UserMapper.xml" />
 

		批量載入mapper 和spring整合後，使用mapper掃描器，這裡不需要配置了 
		<package name="cn.study.mybatis.dao" />
	</mappers>

</configuration>

如果有多個mapper.xml則需要寫N個繁瑣且程式碼冗雜，所以與spring整合後用下面的方式會方面很多：

<?xml version="1.0" encoding="UTF-8"?>

	<!-- myBatis檔案 -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<!-- 自動掃描entity目錄, 省掉Configuration.xml裡的手工配置 -->
		<property name="mapperLocations" value="classpath*:com/gbanker/golddashi/**/mapper/*.xml" />
 

                <!-- 配置實體對映別名在*.xml中直接使用類名即可 -->

<property name="typeAliasesPackage" value="com.study.ssm.**.po" /><property name="configLocation" value="classpath:config/MybatisConf.xml"></property></bean><!-- 掃包 --><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
 <property name="basePackage" value="com.study.ssm.**.dao" /><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /></bean></beans> 大家如果覺得有哪裡不對歡迎指出，謝謝。http://blog.csdn.net/y534560449
