二、web.xml

　　

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

    <!-- 通过注解，把URL映射到Controller类的方法上 -->

    </bean>
    
    <context:component-scan base-package="com.smartpay.demoweb.**.**"/>

            <list>

        <property name="dataSource" ref="dataSource" />
    </bean>

    <context:component-scan base-package="com.**.dao" />

</beans>

四、ibatis配置：

　　sqlMapConfig.xml：

<?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>
      <settings
        cacheModelsEnabled="true"
        lazyLoadingEnabled="true"
        enhancementEnabled="true"
        maxSessions="64"
        maxTransactions="20"
        maxRequests="128"
        useStatementNamespaces="true"/>
    
    <!-- 这里无需配置sqlMap,可以通过spring的配置加载某个目录的多个SqlMap.xml-->
    <sqlMap resource="ibatis/emptyForIbatisParse_sqlmap.xml"/>
    
</sqlMapConfig>

emptyForIbatisParse_sqlmap.xml：

　　

<?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">

<!-- only for ibatis parse -->
<sqlMap namespace="emptyOnlyForIbatisParse_sqlmap">

</sqlMap>
