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>

package com.sxiic.util;


import java.io.IOException;
import java.util.ArrayList;
import java.util.Collections;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Set;


import org.jdom2.Document;
import org.jdom2.Element;
import org.jdom2.JDOMException;
import org.jdom2.input.SAXBuilder;


import com.sxiic.entity.Bank;


public class BankHfXmlUtil {
private static Map<String, Bank> bankMap = new HashMap<String, Bank>();
// 配置文件名称
private static final String conifgName = "/bankhf.xml";
private static BankHfXmlUtil instance;
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;
}


/**
* 获取属性列表
* 
* @return
*/
public static Map<String, Bank> getBankMap() {
if (null == instance) {
getInstance();
initBankMap();
}
return bankMap;
}




private static void initBankMap() {
Element root = document.getRootElement();// 获得根节点
List<Element> list = root.getChildren();
// 省份id
for (int i = 0; i < list.size(); i++) {
Element element = list.get(i);
Bank bank = new Bank();

Element key = element.getChild("key");
bank.setId(key.getTextTrim());
//System.out.println(key.getTextTrim());

Element value = element.getChild("value");
bank.setName(value.getTextTrim());
//System.out.println(value.getTextTrim());

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




}

public class Bank {


private String id;
private String name;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}

}

control.java

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

/**
* 获取银行列表
* 
* @param model
*/
@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>
