目录
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();
