一、依赖引入

<dependency>
<groupid>net.sourceforge.jexcelapi</groupid>
<artifactid>jxl</artifactid>
<version> 2.6 . 12 </version>
</dependency>

二、表格操作
1、读取xls文件
测试文件为:

public void test() throws ioexception, biffexception {
// 1、获取文件,创建workbook
file file = new file( "d:/test/自动化监测数据上传模板20210525.xls" );
workbook workbook = workbook.getworkbook(file);
// 2.获取第一个工作表
sheet sheet = workbook.getsheet( 0 );
// 3.获取表中数据
range[] rangecell = sheet.getmergedcells();
system.out.println( "行:" + sheet.getrows());
system.out.println( "列:" + sheet.getcolumns());
for ( int i = 0 ; i < sheet.getrows(); i++) {
for ( int j = 0 ; j < sheet.getcolumns(); j++) {
cell cell = sheet.getcell(j, i);
string contents = cell.getcontents();
system.out.print(contents + " " );
}
system.out.println();
}
workbook.close();
}

输出结果(注意合并单元格处,需要特殊处理):
改造代码如下:

}
}
system.out.print(contents + " " );
}
system.out.println();
}
workbook.close();
