SpringMvc+POI 處理Excel的匯入操作需要的所有環境

本人用的是JDK8+spring4.28+tomcat8.0

以上是jar包


以上是結構

需要改的地方:第一處:

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


第二處: 
for (int y = row.getFirstCellNum(); y < row.getLastCellNum(); y++) {
cell = row.getCell(y);
if(cell==null){
li.add("");
}else{

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


第三處:處理資料型別的問題
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);
}

第四處:前後綴被我註解掉了

<!-- 檢視解釋類 -->  
     <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>

第五處:spring版本的標頭檔案

</beans>

</beans>

第六處:防止可能的中文亂碼

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>
