Java读取excel文件生成xml文档和JSON文档

Java读取excel文件生成xml文档和JSON文档

目录(?)[+]

1.读取Excel文档中的内容

注意：刚开始在网上下了jlx.rar文件，没注意直接把jlx.rar当成jar包导进去了，在写代码时候纠结了，死活找不到相关jxl.jar包下面的类！各位看客注意了导包的时候一定要导入.jar包 rar与jar 真的好像 眼睛睁大
放亮了呵呵！

jlx.jar包下载地址：

[java] view
plaincopy

<span style="font-size:14px;">package com.jun.excel;

import java.io.FileInputStream;

import java.io.InputStream;

import jxl.Cell;

import jxl.Sheet;

import jxl.Workbook;

public class ImportUser

{

public static void main(String[] args)

{

readExcelFile();

}

//读取d://test.xls文件

private static void readExcelFile() {

// TODO Auto-generated method stub

try

{

String sourcefile = "d://test.xls";

InputStream is = new FileInputStream(sourcefile);

Workbook rwb = Workbook.getWorkbook(is);

//获得总的Sheets，得到sheet的层数

Sheet[] sheets = rwb.getSheets();

int sheetLen = sheets.length;

//获得第一个Sheets 的结果

jxl.Sheet rs = rwb.getSheet(0);

int num_row = rs.getRows();//得到行数

int num_column=rs.getColumns();//得到列数

for(int j=0;j < num_row ;j++)

{

Cell[] cell = rs.getRow(j);//得到第j行的所有值

for(int column_index=0;column_index<num_column;column_index++){

String value = cell[column_index].getContents();//得到第j行，第column_indexs列的值

System.out.print(""+""+rs.getRow(j)[column_index].getContents()+" ");

}

System.out.println("");

}

}

catch(Exception ex)

{

ex.printStackTrace();

}

}

}</span>

2.生成xml文档

生成XML文档类的主要代码：

[java] view
plaincopy

package com.jun.createxml;

import java.io.FileOutputStream;

import javax.xml.parsers.DocumentBuilder;

import javax.xml.parsers.DocumentBuilderFactory;

import javax.xml.transform.Result;

import javax.xml.transform.Source;

import javax.xml.transform.Transformer;

import javax.xml.transform.TransformerFactory;

import javax.xml.transform.dom.DOMSource;

import javax.xml.transform.stream.StreamResult;

import org.w3c.dom.Document;

import org.w3c.dom.Element;

import org.w3c.dom.Node;

import com.jun.excel.ImportUser;

public class CreateXML {

DocumentBuilderFactory dbf = null;

DocumentBuilder db = null;

Document doc = null;

TransformerFactory tff = null;

Transformer tf = null;

Source in = null;

Result out = null;

String xmlpath = null;

public CreateXML()throws Exception

{

dbf = DocumentBuilderFactory.newInstance();//实例化工厂类

dbf.setValidating(false);//不进行有效性检查

dbf.setNamespaceAware(true);

db = dbf.newDocumentBuilder();//实例化DocumentBuilder类

doc = (Document) db.newDocument();//实例化Document类

tff = TransformerFactory.newInstance();

tf = tff.newTransformer();

in=new DOMSource((Node) doc);

}

/*=====================================================

*============生成xml文件

*=====================================================*/

public void ProuduceXml(String axmlpath)

{

try

{

Element users = ((org.w3c.dom.Document) doc).createElement("users");//生产根元素students

((Node) doc).appendChild(users);//将根元素添加到根节点后面

for(int i=0;i<ImportUser.userList.size();i++){

Element user = ProuduceElement(ImportUser.userList.get(i).getName(), ImportUser.userList.get(i).getAge(),ImportUser.userList.get(i).getAddress(),ImportUser.userList.get(i).getPhone());

users.appendChild(user);

}

xmlpath = axmlpath;

out=new StreamResult(new FileOutputStream(xmlpath+"tr.xml"));//生成输出源

tf.transform(in,out);

}

catch(Exception e)

{

System.out.println(e.getMessage());

}

}

public Element ProuduceElement(String aname, String _age,String _address,String _phone) throws Exception

{

Element user = ((org.w3c.dom.Document) doc).createElement("student");//生成student元素(students的子元素)

Element name = ((org.w3c.dom.Document) doc).createElement("name");//创建name子元素

name.appendChild(((org.w3c.dom.Document) doc).createTextNode(aname));//在name元素后添加文本节点

user.appendChild(name);//添加student的子元素name

//设置student的属性id的值

Element age = doc.createElement("age");

age.appendChild(doc.createTextNode(_age));

user.appendChild(age);

Element address = doc.createElement("address");

age.appendChild(doc.createTextNode(_address));

user.appendChild(address);

Element phone= doc.createElement("phone");

age.appendChild(doc.createTextNode(_phone));

user.appendChild(address);

return user;

}

}

在main函数中调用的方法：

[java] view
plaincopy

//创建XML文档

private static void createXMLFile() {

// TODO Auto-generated method stub

try

{

CreateXML xml=new CreateXML();

xml.ProuduceXml(xmlpath);

}

catch(Exception e)

{

System.out.println("main:\n"+e.getMessage());

}

}

3.生成json文档
