需求描述

客户要求导出的txt文件内容对齐，切没有边框。

需求实现

 

利用api导出txt文件，在导出之前设置ReportDefine的边框为无边框再利用ReportUtils.exportToText(os, ireport);方法导出即可。

 

示例代码如下：

import java.io.FileInputStream;

import java.io.FileNotFoundException;

import java.io.FileOutputStream;

import java.io.InputStream;

import java.io.OutputStream;

import java.io.OutputStreamWriter;

import com.runqian.report4.model.ReportDefine;

import com.runqian.report4.model.engine.ExtCellSet;

import com.runqian.report4.usermodel.Context;

import com.runqian.report4.usermodel.Engine;

import com.runqian.report4.usermodel.IReport;

import com.runqian.report4.util.ReportUtils;

import com.runqian.report4.view.text.TextFile;

public class TestTextReport {

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

// TODO Auto-generated method stub

ReportDefine rd = (ReportDefine)ReportUtils.read(“d:\\Program Files (x86)\\reportHome4543\\webapps\\demo\\reportFiles\\test_txt.raq”);

//TextFile textFile = new TextFile(ireport,” “,”\n”);

//String text = textFile.toString();

//System.out.println(text);

int r = rd.getRowCount();

int c = rd.getColCount();

for(int i=1;i<=r;i++){

for(int j=1;j<=c;j++){

//rd.setTBWidth(i, (short)j, (float)1);

rd.setBBStyle(i, (short)j, (byte)80);

rd.setTBStyle(i, (short)j, (byte)80);

rd.setLBStyle(i, (short)j, (byte)80);

rd.setRBStyle(i, (short)j, (byte)80);

}

}

 

Context ctx = new Context();

Engine engine = new Engine(rd,ctx);

IReport ireport = engine.calc();

ExtCellSet.setLicenseFileName(“d:\\Program Files (x86)\\reportHome4543\\webapps\\demo\\WEB-INF\\classes\\runqianWindowServer.lic”);//设置授权

OutputStream os = new FileOutputStream(“D:\\TEXT.txt”);//创建导出的输出流

ReportUtils.exportToText(os, ireport);

 

OutputStreamWriter osw = new OutputStreamWriter(os);

//osw.write(text,0,text.length());//内容写到流中

osw.close();

os.close();

}

}
