[置顶] SpringMvc+POI 处理Excel的导入操作需要的所有环境

本人用的是JDK8+spring4.28+tomcat8.0



以上是jar包



以上是结构

需要改的地方：第一处：

for (int j = sheet.getFirstRowNum(); j <sheet.getLastRowNum()+1; j++)

第二处： 
for (int y = row.getFirstCellNum(); y < row.getLastCellNum(); y++) {
cell = row.getCell(y);
if(cell==null){
li.add("");
}else{

li.add(this.getCellValue(cell));}
}

第三处：处理数据类型的问题

case Cell.CELL_TYPE_NUMERIC:
if("m/d/yy".equals(cell.getCellStyle().getDataFormatString())){
value = sdf.format(cell.getDateCellValue());
}else{
HSSFDataFormatter dataFormatter = new HSSFDataFormatter();
value = dataFormatter.formatCellValue(cell);
}

第四处：前后缀被我注解掉了

<!-- 视图解释类 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- <property name="prefix" value="/WEB-INF/jsp/"></property>
<property name="suffix" value=".jsp"></property> -->
</bean>
第五处：spring版本的头文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</beans>
</beans>

第六处：防止可能的中文乱码

在web.xml中加

<filter>
<filter-name>SetCharacterEncoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>SetCharacterEncoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
