如何在jsp中获取java控制台输出 [英] How can get java console output to view in jsp

问题描述

我在javaclass.how的excel文件中使用forloop获取getnumbersheets我可以在jsp中显示所有工作表的radiobutton的工作表名



我尝试过：



package com;



import java.io.FileInputStream;



import java.io.IOException;

import java.util.ArrayList;



import org.apache.poi.xssf.usermodel.XSSFWorkbook;



public class ExcelDataParser

{

private ArrayList< string> arr;



public ArrayList< string> getArr（）{

return arr;

}



public void setArr（ArrayList< string> arr） {

this.arr = arr;

}

// public static void getSheetNames（）

public static void main（String args []）抛出IOException

{

ArrayList< string> arr = new ArrayList< string>（）;



try {

String str =C：\\Downloads\\\ \\ _Associate_Details.xlsx;



FileInputStream fileInputStream = null;



fileInputStream = new FileInputStream（str） ;

XSSFWorkbook工作簿=新的XSSFWorkbook（fileInputStream）;

字符串工作;

for（int i = 0; i< workbook.getNumberOfSheets （）; i ++）

{



work = workbook.getSheetName（i）;

arr.add （工作）;

}

System.out.println（arr）;

workbook.close（）;

} catch（IOException e）{

// TODO自动生成的捕获块

e.printStackTrace（）;

}}



}

解决方案

为了在jsp页面中显示输出，你必须使用out.write（ ）; method.so，在for循环中使用

 out.write（< input type =radio>+ work +< br>）; 

am using forloop for getnumbersheets in excel file in javaclass.how can i display sheetnames in jsp with radiobutton for all sheets

What I have tried:

package com;

import java.io.FileInputStream;

import java.io.IOException;
import java.util.ArrayList;

import org.apache.poi.xssf.usermodel.XSSFWorkbook;

public class ExcelDataParser
{
private ArrayList<string>arr;

public ArrayList<string> getArr() {
return arr;
}

public void setArr(ArrayList<string> arr) {
this.arr = arr;
}
//public static void getSheetNames()
public static void main(String args[]) throws IOException
{
ArrayList<string> arr=new ArrayList<string>();

try {
String str="C:\\Downloads\\Associate_Details.xlsx";

FileInputStream fileInputStream = null;

fileInputStream = new FileInputStream(str);
XSSFWorkbook workbook = new XSSFWorkbook(fileInputStream);
String work;
for (int i = 0; i < workbook.getNumberOfSheets(); i++)
{

work=workbook.getSheetName(i);
arr.add(work);
}
System.out.println(arr);
workbook.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}}

}

解决方案

In order to show the output in jsp page you have to use out.write(); method.so, inside your for loop use

out.write("<input type="radio">"+work+"<br>");
