xml的使用

例子一：

获取银行的code 和value

bankhf.xml

<?xml version="1.0" encoding="UTF-8"?>

<banktype>

<property>

<key>01020000</key>

<value>中国工商银行</value>

</property>

<property>

<key>01030000</key>

<value>中国农业银行</value>

</property>

</banktype>

private static Document document;

public BankHfXmlUtil() {

SAXBuilder builder = new SAXBuilder();

try {

document = builder.build(getClass().getResourceAsStream(conifgName));

} catch (JDOMException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}

}

private synchronized static BankHfXmlUtil getInstance() {

if (null == instance) {

instance = new BankHfXmlUtil();

}

return instance;

}

/**

public static Map<String, Bank> getBankMap() {

if (null == instance) {

initBankMap();

}

return bankMap;

}

private static void initBankMap() {

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

Element key = element.getChild("key");

bank.setId(key.getTextTrim());

//System.out.println(key.getTextTrim());

bank.setName(value.getTextTrim());

//System.out.println(value.getTextTrim());

bankMap.put(key.getTextTrim(), bank);

}

}

}

public class Bank {

}

control.java

BankHfXmlUtil.getBankMap().get(ewvo.getBankType()).getName()

/**

*/

@RequestMapping(value = "/banklist", method = RequestMethod.GET)

@ResponseBody

public List<Bank> getBanks(Model model) {

List<Bank> bankList = new ArrayList<Bank>();

Map<String, Bank> bankMap = BankHfXmlUtil.getBankMap();

Set<String> bidlist = bankMap.keySet();

List<String> list = new ArrayList<String>(bidlist);

Collections.sort(list); // XML文件中的顺序取出来后，需要排序

for (String bid : list) {

Bank bank = new Bank();

bank.setId(bid);

bank.setName(bankMap.get(bid).getName());

bankList.add(bank);

}

return bankList;

}

bank.js

var getprourl = "select/banklist";

// 获取省份列表，页面加载后立即请求

$(document).ready(

function() {

var hd = $("#btid").val();

$.ajax({

url : getprourl, // 为请求的url

type : "get", // get请求方式

dataType : "json",

success : function(msg) { // 其中msg是服务器上返回的数据，可以alert查看一下

//alert("初始化加载省份信息");

var str = "<option value=''>银行类型</option>";

$.each(msg, function(i, item) {

if (hd == item.id) {

str = str + "<option selected='selected' value='" + item.id + "'>" + item.name + "</option>";

} else {

str = str + "<option value='" + item.id + "'>" + item.name + "</option>";

}

});

$("#bankType").empty();

$("#bankType").append(str);

}

});

});

bank.html

<form:select path="bankType"></form:select>

<input id="btid" name="btid" value="${withdrawals.bankType}" type="hidden" />

---结束

使用列子二：

获取省市，格式如下:

area.xml

<?xml version="1.0" encoding="UTF-8"?>

<dict>

<key>00</key>

<dict>

<key>北京市</key>

<dict>

<key>00</key>

<dict>

<key>北京市</key>

<array>

<string>东城区</string>

<string>西城区</string>

<string>朝阳区</string>

<string>丰台区</string>

<string>石景山区</string>

</array>

</dict>

</dict>

</dict>

<key>01</key>

<dict>

<key>天津市</key>

<dict>

<key>00</key>

<dict>

<key>天津市</key>

<array>

<string>和平区</string>

<string>河东区</string>

<string>河西区</string>

<string>南开区</string>

</array>

</dict>

</dict>

</dict>

</dict>
