之前使用poi匯出Excel表格，需要配置很多東西，也比較麻煩，這裡使用poi的封裝easypoi，可以快速配置，實現Excel或者word檔案的匯出。這裡我們結合SpringMVC開發easypoi。

匯入jar包

這裡是springMVC和easypoi所需的jar包

主要是easypoi-base和easypoi-web，其它都是關聯所需的jar包，我們需要commons-lang3.jar包，開始使用commons-lang2.6版本會出現錯誤。

spring-servlet.xml配置

<!-- Bean解析器,級別高於預設解析器,尋找bean物件進行二次處理 -->
<bean id="beanNameViewResolver"
		class="org.springframework.web.servlet.view.BeanNameViewResolver" p:order="0">
</bean>
 

	<!-- Excel 處理 根據使用者輸入進行物件處理 -->
	<bean id="jeecgExcelView" class="org.jeecgframework.poi.excel.view.JeecgSingleExcelView" />
	<bean id="jeecgTemplateExcelView" class="org.jeecgframework.poi.excel.view.JeecgTemplateExcelView" />
	<bean id="jeecgTemplateWordView" class="org.jeecgframework.poi.excel.view.JeecgTemplateWordView" />
	<bean id="jeecgMapExcelView" class="org.jeecgframework.poi.excel.view.JeecgMapExcelView" />
