1获取两个地址间距离
获取两个地址间距离，实现方式比较多，例如基于百度地图api，高德地图api，下面基于高德地图api实现，代码如下：
private static String getLonLat(String address)throws Exception{//返回输入地址address的经纬度信息, 格式是 经度,纬度 String address2 = URLEncoder.encode(address,"UTF-8"); String queryUrl = "http://restapi.amap.com/v3/geocode/geo?key=aba6ce2149823adf738cdbe6fbb&address="+address2; String queryResult = getResponse(queryUrl); //高德接品返回的是JSON格式的字符串 // System.out.println(address+"//"+queryResult); JSONObject jo = new JSONObject().fromObject(queryResult); JSONArray ja = jo.getJSONArray("geocodes"); return new JSONObject().fromObject(ja.getString(0)).get("location").toString(); } private static Long getDistance(String startLonLat, String endLonLat){//返回起始地startAddr与目的地endAddr之间的距离，单位：米 Long result = new Long(0); String queryUrl = "http://restapi.amap.com/v3/distance?key=aba6ce2149823adf738cdbe6fbb&origins="+startLonLat+"&destination="+endLonLat; String queryResult = getResponse(queryUrl); JSONObject jo = new JSONObject().fromObject(queryResult); JSONArray ja = jo.getJSONArray("results"); result = Long.parseLong(new JSONObject().fromObject(ja.getString(0)).get("distance").toString()); return result; } private static String getResponse(String serverUrl){ StringBuffer result = new StringBuffer(); try { URL url = new URL(serverUrl); URLConnection conn = url.openConnection(); BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream())); String line; while((line = in.readLine()) != null){ result.append(line); } in.close(); } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return result.toString(); }
2起始点、中转点、终点距离实现
距离支持中转站，代码如下：
public static Map<String,String> getDis(String start, String middle, String end){ Map<String,String> map=new Hashtable<String,String>(); map.put("start",start); if(middle!=null){ map.put("middle",middle); } map.put("end",end); if(start==null||"".equals(start.trim())){ map.put("distance","起点不能为空"); return map; } if(end==null||"".equals(end.trim())){ map.put("distance","终点不能为空"); return map; } Long dis=0l; try { if(middle==null||"".equals(middle.trim())){//没有中转点 String startLonLat = getLonLat(start); String endLonLat = getLonLat(end); dis = getDistance(startLonLat, endLonLat); map.put("middle",""); map.put("distance",dis+""); }else{//有中转点 String startLonLat = getLonLat(start); String middleLonLat = getLonLat(middle); String endLonLat = getLonLat(end); dis = getDistance(startLonLat, middleLonLat); dis =dis+ getDistance(middleLonLat, endLonLat); map.put("distance",dis+""); } }catch (Exception e){ //e.printStackTrace(); map.put("distance","获取失败"); } //System.out.println(dis); return map; }
3导出Excel文件
导出Excel文件的默认如下，共四列，包含起始点，途径点，终点以及距离
起始点 途径点 终点 起点到终点距离(米) 北京 石家庄 北京 天津 石家庄 浙江省杭州市西湖区 石家庄藁城市直接上代码
public void exportExcel(List<Map<String,String>> resultlist,String exportPath)throws Exception{ExportData2Excel excel=new ExportData2Excel();HSSFWorkbook workbook = excel.generateWorkbook(resultlist);File xlsFile = new File(exportPath);if(!xlsFile.exists()){xlsFile.createNewFile();}FileOutputStream xlsStream = new FileOutputStream(xlsFile);workbook.write(xlsStream); xlsStream.close();xlsStream.flush();}public HSSFWorkbook generateWorkbook(List<Map<String,String>> orderList)throws Exception {// 声明一个工作薄HSSFWorkbook wb = new HSSFWorkbook();// 声明一个单子并命名HSSFSheet sheet = wb.createSheet("sheet1");// 冻结标题(width * height)// sheet.createFreezePane(15, 1);// 给单子名称一个长度sheet.setDefaultColumnWidth((short) 15);// 生成一个样式HSSFCellStyle style = wb.createCellStyle();// 设置表头颜色HSSFFont font = wb.createFont();font.setColor(HSSFColor.BLUE.index);style.setFont(font);// 水平布局 居中style.setAlignment(HSSFCellStyle.ALIGN_CENTER);// 上下居中style.setVerticalAlignment(HSSFCellStyle.VERTICAL_CENTER);// 不锁定style.setLocked(false);// 设置边框style.setBorderBottom(HSSFCellStyle.BORDER_THIN); // 下边框style.setBorderLeft(HSSFCellStyle.BORDER_THIN);// 左边框style.setBorderTop(HSSFCellStyle.BORDER_THIN);// 上边框style.setBorderRight(HSSFCellStyle.BORDER_THIN);// 右边框// 创建第一行（也可以称为表头）HSSFRow row = sheet.createRow(0);// 样式字体居中style.setAlignment(HSSFCellStyle.ALIGN_CENTER);this.createExcelTitle(row, style);int k = 0;int orderSize = orderList == null ? 0 : orderList.size();for (int i = 0; i < orderSize; i++) {k++;row = sheet.createRow(k);this.addExcelContent(row, orderList.get(i));// row.createCell((short) 1).setCellValue(new// HSSFRichTextString(StringUtil.isNullObject(orderList.get(i).get("orderId")+"")));// System.out.println(orderList.get(i));}return wb;} /** * * 功能描述：创建工单title. * */private void createExcelTitle(HSSFRow row, HSSFCellStyle style) {String[] titles = { "起始点","途径点","终点","起点到终点距离(米)" };for (int i = 0; i < titles.length; i++) {String title = titles[i];// 给表头第一行一次创建单元格HSSFCell cell = row.createCell((short) i);cell.setCellValue(title);cell.setCellStyle(style);}} private void addExcelContent(HSSFRow row, Map<String,String> pageData) {String[] fields = { "start","middle", "end" ,"distance"};for (int i = 0; i < fields.length; i++) {String field = fields[i];row.createCell((short) i).setCellValue(new HSSFRichTextString(pageData.get(field) + ""));}}
4封装成客户端工具
下面就用JFrame封装，封装后的界面如下：
代码如下
public class AreaUI extends JFrame { private JButton btn; private JPanel contentPane; //内容面板 private JTextField textField; //文本框 JButton okBtn ;//地址获取按钮 public AreaUI() { setTitle("批量获取地址间距离工具"); //设置窗体的标题 setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //设置窗体退出时操作 setBounds(100, 100, 800, 400); //设置窗体位置和大小 contentPane = new JPanel(); //创建内容面板 contentPane.setBorder(new EmptyBorder(100, 5, 5, 5)); //设置面板的边框 contentPane.setLayout(new BorderLayout(0, 0)); //设置内容面板为边界布局 setContentPane(contentPane); //应用内容面板 JPanel panel1 = new JPanel(); //新建面板用于保存文本框 panel1.setBounds(5, 100, 800, 100); contentPane.add(panel1, BorderLayout.NORTH); //将面板放置在边界布局的北部 textField = new JTextField(); //新建文本框 panel1.add(textField); //将文本框增加到面板中 textField.setPreferredSize(new Dimension(400, 40)); final JButton btn = new JButton("选择文件"); btn.setPreferredSize(new Dimension(100, 40)); panel1.add(btn); JPanel panel2 = new JPanel(); //新建面板用于保存按钮 contentPane.add(panel2, BorderLayout.CENTER); //将面板放置在边界布局的中央 okBtn = new JButton("批量获取"); okBtn.setPreferredSize(new Dimension(100, 40)); panel2.add(okBtn); setVisible(true); btn.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { //按钮点击事件 JFileChooser chooser = new JFileChooser(); //设置选择器 chooser.setMultiSelectionEnabled(true); //设为多选 int returnVal = chooser.showOpenDialog(btn); //是否打开文件选择框 if (returnVal == JFileChooser.APPROVE_OPTION) { //如果符合文件类型 String filepath = chooser.getSelectedFile().getAbsolutePath(); //获取绝对路径 //System.out.println(filepath); textField.setText(filepath); } } }); /* 确定点击 */ okBtn.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { String filepath = textField.getText(); if ("".equals(filepath) || filepath == null) { JOptionPane.showMessageDialog(getContentPane(), "请先选择文件","警告", JOptionPane.WARNING_MESSAGE); return; } String suffix = filepath.substring(filepath.lastIndexOf(".") + 1); if (!(suffix.equals("xlsx") || (suffix.equals("xls")))) { JOptionPane.showMessageDialog(getContentPane(), "请选择Excel文件","警告", JOptionPane.WARNING_MESSAGE); return; } File exitFile=new File(filepath); if(!exitFile.exists()){ JOptionPane.showMessageDialog(getContentPane(), "文件地址不存在","警告", JOptionPane.WARNING_MESSAGE); return; } try { List<DistanceVO> list =openFile(filepath); /* 打开文件 */ if(list==null||list.isEmpty()){ JOptionPane.showMessageDialog(getContentPane(), "解析Excel失败","警告", JOptionPane.WARNING_MESSAGE); return; } List<Map<String,String>> pageDataList=new ArrayList<Map<String,String>>(); int listSize=list.size(); int listIndexNum=0; System.out.println("共需要获取"+listSize+"个"); for(DistanceVO distanceVO:list){ listIndexNum++; Map<String,String> map=DistanceUtil.getDis(distanceVO.getStart(),distanceVO.getMiddle(),distanceVO.getEnd()); pageDataList.add(map); if(listIndexNum%100==0){ System.out.println(getCurTime()+"使劲获取中，共"+listSize+"已获取"+listIndexNum+"个"); } } System.out.println("地址已全部获取完成……"); ExportData2Excel exportData2Excel=new ExportData2Excel(); String exportPath=""; if (suffix.equals("xlsx")){ exportPath=filepath.replaceAll(".xlsx","转化后.xls"); }else if(suffix.equals("xls")){ exportPath=filepath.replaceAll(".xls","转化后.xls"); } exportData2Excel.exportExcel(pageDataList,exportPath); JOptionPane.showMessageDialog(getContentPane(), "获取后文件保存地址："+exportPath,"提示", JOptionPane.INFORMATION_MESSAGE); } catch (Exception e1) { e1.printStackTrace(); } okBtn.setText("地址获取"); } }); } /* 打开对应的Excel文件 */ public List<DistanceVO> openFile(String filepath) throws IOException { FileInputStream fileInputStream = new FileInputStream(new File(filepath)); XSSFWorkbook workbook = new XSSFWorkbook(fileInputStream); List<DistanceVO> list= queryRows(workbook); if(fileInputStream!=null){ fileInputStream.close(); } return list; } /* 检索需要信息 */ public List<DistanceVO> queryRows(XSSFWorkbook workbook) { List<DistanceVO> list = new ArrayList<>(); XSSFSheet sheet = workbook.getSheetAt(0); for (int i = 1; i <= sheet.getLastRowNum(); i++) { //System.out.println(sheet.getRow(i).getCell(0).getStringCellValue()); DistanceVO vo=new DistanceVO(); vo.setStart(sheet.getRow(i).getCell(0).getStringCellValue()); try { vo.setMiddle(sheet.getRow(i).getCell(1).getStringCellValue()); }catch (Exception e){} vo.setEnd(sheet.getRow(i).getCell(2).getStringCellValue()); list.add(vo); } return list; } private String getCurTime(){ SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");//设置日期格式 return df.format(new Date()); } public static void main(String[] args) { AreaUI ui= new AreaUI(); }
