篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了POI setCellStyle 没有效果相关的知识，希望对你有一定的参考价值。
HSSFWorkbook outWB = new HSSFWorkbook();
HSSFSheet outSheet = outWB.createSheet("Sheet1");
HSSFRow outFstRow = outSheet.createRow((short)0);
HSSFRow outRow = outSheet.createRow((short)1);
HSSFCellStyle cellStyle = outWB.createCellStyle();
HSSFCellStyle cellStyleclor = outWB.createCellStyle();
cellStyleclor.setFillForegroundColor(HSSFColor.RED.index);
cellStyleclor.setFillBackgroundColor(HSSFColor.BLUE.index);
for(int m=0;m<columnList.size();m++)
column =columnList.get(m)+"";
HSSFCell outCell = outFstRow.createCell((short)m);
outCell.setCellValue(column);
outCell.setCellStyle(cellStyleclor);
为什么出来的 excel 单元格 颜色没变化？ 我哪写错了？
----------------------------------------------------------------
setFillBackgroundColor(HSSFColor.GREEN.index);
//设定单元个背景颜色
style.setFillForegroundColor(HSSFColor.RED.index);
//设置单元格显示颜色本回答被提问者采纳 参考技术B 你没用实体点填充，所以颜色出不来。
cellStyleclor.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);<——加上这个
cellStyleclor.setFillForegroundColor(HSSFColor.RED.index); 参考技术C 你好。楼主。我专门来骂你的。
真想用最脏的话来形容你。NM%$#^%#你个大S……%￥&之类的。
我看见你好几处帖子不回。解决了也不说怎么解决了。你这种人，真让人恶心。
poi导入excel
Spring+SpringMVC+Maven+MyBatis+Mysql此环境下的POI导入
此文档讲解Excel导入的功能
1.1 POI导入excel
浏览器效果展示：
前端代码
前端Html代码：
<!-- 导入 -->
<div class="layui-inline">
<div class="layui-input-block" style="margin-left: 10px;">
<button type="button" permission="49" class="layui-btn layui-btn-small">
<input type="file" name="picture" id="picture">
</button>
</div>
</div>
<div class="layui-inline">
<div class="layui-input-block" style="margin-left: 10px;">
<button type="button" permission="49" id="scheduExcel" class="layui-btn layui-btn-small">Excel导入</button>
</div>
</div>
<!-- 导出 -->
<div class="layui-inline">
<div class="layui-input-block" style="margin-left: 10px;">
<button type="button" permission="49" id="exportExcel" class="layui-btn layui-btn-small">Excel导出</button>
</div>
</div>
Js代码
//JS校验form表单信息
<script>
function checkData() {
var fileDir = $("#picture").val();
var suffix = fileDir.substr(fileDir.lastIndexOf("."));
if("" == fileDir) {
alert("选择需要导入的Excel文件！");
return false;
}
if(".xls" != suffix && ".xlsx" != suffix) {
alert("选择Excel格式的文件导入！");
return false;
}
return true;
}
//Excel表格导入
var importExcelhospDeptDoc = function() {
if(!checkData()) {
return;
}
//表单传值
var form = new FormData(document.getElementById("excelScheduForm"));
$.ajax({
type: "post",
dataType: "json",
processData: false, //表单传值必须
contentType: false, //表单传值必须
url: "/importExcel/importShopingOrder",
data: form,
success: function(msg) {
//debugger;
if(msg.resultCode == 200) {
alert(msg.msg);
window.location.reload();
} else if(msg.resultCode == 400) {
alert(msg.msg);
document.getElementById("errorSoCode").innerText=msg.content;
document.getElementById("picture").value="";
}
}
});
}
//导入商城订单
$(‘#scheduExcel‘).on(‘click‘, function() {
importExcelhospDeptDoc();
});
</script>
