用java实现:上传excl表格。读取数据,输出结果。

package chexianchaxun;
import java.io.*;

public class FeiYong{
public static void main(String[] args) throws Exception {

    java.net.URL url = new java.net.URL("http://********");
    java.net.URLConnection con = url.openConnection();
    con.setUseCaches(false);
    con.setDoOutput(true);
    con.setDoInput(true);

    DataOutputStream dataOut = new DataOutputStream(con.getOutputStream());
    //字节流:InputStream(读取)、OutputStream(写入)
    String Msg = "<Request> <VinNo>ZAMJK39E6B0060491</VinNo><LicenseNo></LicenseNo><LoginID>215288</LoginID></Request>" ;

    /**转保车辆VinNo为必填
*/
    System.out.println(Msg);
    //字符流:Writer(写入)、Reader(读取)
    dataOut.write(Msg.getBytes("gbk"));//将已经解析出来的字节数据转化为gbk编码格式的字符串
    dataOut.flush();
    dataOut.close();
    InputStream is = con.getInputStream();
    InputStreamReader isr = new InputStreamReader(is, "gbk");
    BufferedReader br = new BufferedReader(isr);
    StringBuffer sb = new StringBuffer();

    String templine=null;
    while ((templine = br.readLine()) != null)
        sb.append(templine);

    System.out.println(sb.toString());
}

}
如上。
当个输入信息车架号,通过接口,可以获取对应的数据信息。
现需要实现,excl表格形式上传,表格内有多条车辆的车架号数据,通过接口,然后再获取对应的数据信息。

感谢Always_MyLoverX 的耐心回答

443193862@qq.com,楼主把你的代码、部署环境描述发过来,给你贴代码估计你系统也跑不起来,我可以给你做个简单上传demo,你自己根据业务再扩展

Java 也有NPOI 可以用

java有专门针对excel操作的类及函数。可以找一下。话说我们以后不会是同事吧?

1、确认模板 。 2、用org.apache.poi实现表格生成上传。

InputStream inp = new FileInputStream("F://downloads/wordbook.xlsx");

Workbook wb = WorkbookFactory.create(inp);

Sheet sheet = wb.getSheetAt(0);
Row row = sheet.getRow(2);

Cell cell = row.getCell(3);
System.out.println(cell.getNumericCellValue());


function upload${prefix_file}() {
var book = document.getElementById('${prefix_file}file-restBook-1');
var files = book.files;
var file = files[0];
if(!file) {
$.messager.alert("提示", "请选择上传文件!", "info");
return;
}
var name = file.name

;
if(name.indexOf(".") == -1) {
$.messager.alert("提示", "请按照模板上传 Excel 文件!", "info");
return;
}
var suffix = name.substring(name.indexOf(".") + 1);
if( suffix != "xls" && suffix != "xlsx") {
$.messager.alert("提示", "请按照模板上传 Excel 文件!", "info");
return;
}

        var reader = new FileReader();
        reader.onload = function(e) {
            var data = e.target.result;
            //var wb = XLSX.read(data, {type: 'binary'});
            var arr = String.fromCharCode.apply(null, new Uint8Array(data));
            var wb = XLSX.read(btoa(arr), {type: 'base64'});
            var sheet = wb.Sheets[wb.SheetNames[0]];
            var jsono = XLSX.utils.sheet_to_row_object_array(sheet);
            var jsons = JSON.stringify(jsono);
            $.ajax({
                url : "${ctx}/book/parseExcel.shtml",
                method : "post",
                dataType : "json",
                data : {
                    "data" : jsons,
                },
                success : function(data) {
                    var result = eval(data);
                    $.messager.alert("提示",  result.msg, "info", function() {
                        parent.closeUploadWin${win_id}();
                    });
                },
                error : function(XMLHttpRequest, textStatus, errorThrown) {
                    $.messager.alert("提示", "页面出现异常,请联系管理员!", "error");
                }
            });
        };
        //reader.readAsBinaryString(file);
        reader.readAsArrayBuffer(file);
    }

fileChooser = new JFileChooser();

//过滤Excel文件,只寻找以xls结尾的Excel文件,如果想过滤word文档也可以写上doc

//获取该工作表中的第一个工作表

            之前项目上用到的,java读取excel数据,实体类换成你自己的 直接用
