spring 实现Excel的导出下载功能

1.在xml中配置：

<!--基金基本资料 Excel导出 -->
 <bean id="TestExcelController" class="cn.fund.system.Xsl.impl.TestExcelController">
  <property name="commandClass">
    <value>cn.fund.code.model.JzhqView</value>
  </property>
 </bean>
 <bean id="ListInfoUseExcel" class="cn.fund.system.Xsl.impl.ListInfoUseExcel"></bean>

 

<prop key="/excel.dos">TestExcelController</prop>

}利用java操作xls文件总结：
1.jxl行对于poi功能弱一点，但是jxlAPI对中文支持很好，并不依赖于windows系统，即使运行于Linux下，它同样能够处理excel文件。另外需要说明的是，这套API对图形和图表的支持很有限，而且仅仅识别PNG格式。
