Java导出数据为EXCEL的两种方式JXL和POI

JXL和POI导出数据方式的比较

POI支持excel2003和2007，而jxl只支持excel2003。

下面为测试代码：

Java代码  收藏代码
  1. public class TestCondition {  
  2.       
  3.     /** 
  4.      * 生成的记录条数 
  5.      */  
  6.     public static final int RECORD_COUNT = 21000;  
  7.       
  8.     /** 
  9.      * 模板文件 
  10.      */  
  11.     public static final String TEMPLATE_FILE = "E:/MyKernelPlatformWorkspace/Template/query_order.xls";  
  12.       
  13.     /** 
  14.      * JXL生成文件位置 
  15.      */  
  16.     public static final String JXL_TARGET_FILE_NAME = "E:/MyKernelPlatformWorkspace/Template/target/jxl_order.xls";  
  17.       
  18.     /** 
  19.      * POI生成文件位置 
  20.      */  
  21.     public static final String POI_TARGET_FILE_NAME = "E:/MyKernelPlatformWorkspace/Template/target/poi_order.xls";  
  22.       
  23.     /** 
  24.      * JXL临时文件位置 
  25.      */  
  26.     public static final String JXL_TEMP_DIR = "E:/MyKernelPlatformWorkspace/Template/temp";  
  27.       
  28. }  

 

然后在此测试条件下编写JXL和POI的测试类，首先是JXL的

执行Main函数

  1. public class JXLMain {  
  2.   
  3.     /**     
  4.      * 描述：     
  5.      * @param args     
  6.      * @throws Exception  
  7.      */  
  8.     public static void main(String[] args) throws Exception {  
  9.            
  10.         long jxlStart = System.currentTimeMillis();  
  11.         JXLExcel jxl = new JXLExcel();  
  12.         jxl.execute();  
  13.         long jxlStop = System.currentTimeMillis();  
  14.         System.out.println("jxl takes : " + (jxlStop - jxlStart)/1000 + " seconds.");  
  15.           
  16.     }  

 

 

然后是POI的
