关键?XML XMLBean Parser
一、关于XML解析
(tng) (tng)XML在Java应用E序里变得越来越重要, q泛应用于数据存储和
交换. 比如我们常见的配|文?都是以XML方式存储? XMLq应?br />于Java Message Service和W(xu)eb Services{技术作为数据交?
因此,正确dXML文档是XML应用的基.
(tng) (tng)Java提供?jin)SAX和DOM两种方式用于解析XML,但即便如?要读写一?br />E微复杂的XML,也不是一件容易的?
二、XMLBean?/span>
(tng) (tng) (tng) (tng)Hibernate已经成ؓ(f)目前行的面向Java环境的对?关系数据库映工?
在Hibernate{对?关系数据库映工具出C?Ҏ(gu)据库的操作是
通过JDBC来实现的,Ҏ(gu)据库的Q何操?开发h员都要自己写SQL语句
来实? 对象/关系数据库映工具出现后,Ҏ(gu)据库的操作{成对
JavaBean的操?极大方便?jin)数据库开? 所以如果有一个类似的工具能够
实现对XML的读写{成对JavaBean的操?会(x)化XML的读?即对XML
不熟(zhn)的开发h员(sh)能方便地dXML. q个工具是XMLBean.

四、XMLBean使用步骤
(tng) (tng) (tng) (tng)和其他面向Java环境的对?关系数据库映工L(fng)使用步骤一?
在正式用XMLBean?我们要作两个准备.
(tng) (tng) (tng) (tng)1. 生成XML Schema文g
(tng) (tng) (tng) (tng) (tng) (tng) 什么是XML Schema文g? 正常情况?每个XML文g都有一个Schema文g,
(tng) (tng) (tng) (tng) (tng) (tng) XML Schema文g是一个XML的约束文?它定义了(jin)XML文g的结构和元素.
(tng) (tng) (tng) (tng) (tng) (tng) 以及(qing)对元素和l构的约? 通俗地讲,如果说XML文g是数据库里的记录,
(tng) (tng) (tng) (tng) (tng) (tng) 那么Schema是表结构定?
(tng) (tng) (tng) (tng) (tng) (tng) Z么需要这个文? XMLBean需要通过q个文g知道一个XML文g?br /> (tng) (tng) (tng) (tng) (tng) (tng) l构以及(qing)U束,比如数据cd{? 利用q个Schema文g,XMLBean会(x)产生
(tng) (tng) (tng) (tng) (tng) (tng) 一pd相关的Java Classes来实现对XML的操? 而作为开发h?则是
(tng) (tng) (tng) (tng) (tng) (tng) 利用XMLBean产生的Java Classes来完成对XML的操作而不需要SAX或DOM.
(tng) (tng) (tng) (tng) (tng) (tng) 怎样产生q个Schema文g? 如果对于熟?zhn)XML的开发h?可以自己?br /> (tng) (tng) (tng) (tng) (tng) (tng) 写这个Schema文g,对于不熟(zhn)XML的开发h?可以通过一些工h完成.
(tng) (tng) (tng) (tng) (tng) (tng) 比较有名的如XMLSPY和Stylus Studio都可以通过XML文g来生成Schema
(tng) (tng) (tng) (tng) (tng) (tng) 文g. 加入我们已经生成q个Schema文g(customer.xsd):
(tng) (tng) (tng) (tng) (tng) (tng)

(tng) (tng) (tng) (tng)2. 利用scomp来生成Java Classes
(tng) (tng) (tng) (tng) (tng) (tng) scomp是XMLBean提供的一个编译工?它在bin的目录下. 通过q个工具,
(tng) (tng) (tng) (tng) (tng) (tng) 我们可以以上的Schema文g生成Java Classes.
(tng) (tng) (tng) (tng) (tng) (tng) scomp的语法如?-
(tng) (tng) (tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng) (tng) (tng) scomp [options] [dirs]* [schemaFile.xsd]* [service.wsdl]* [config.xsdconfig]*
(tng) (tng) (tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng) (tng) (tng) 主要参数说明:
(tng) (tng) (tng) (tng) (tng) (tng) -src [dir] (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)-- 生成的Java Classes存放目录
(tng) (tng) (tng) (tng) -srconly (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)-- 不编译Java Classes,不生Jar文g
(tng) (tng) (tng) (tng) -out [jarFileName] (tng) (tng)-- 生成的Jar文g,~省是xmltypes.jar
(tng) (tng) (tng) (tng) (tng) (tng) -compiler (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) -- Java~译器的路径,即Javac的位|?br /> (tng) (tng) (tng) (tng) (tng) (tng) schemaFile.xsd (tng) (tng) (tng) (tng)-- XML Schema文g位置
(tng) (tng) (tng) (tng) (tng) (tng) config.xsdconfig (tng) (tng) -- xsdconfig文g的位|? q个文g主要用来制定生成的Java Class
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)的一些文件名规则和Package的名U?在本?package是sample.xmlbean
(tng) (tng) (tng) (tng) (tng) (tng) 在本?我是q样q行?
(tng) (tng) (tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng) (tng) (tng) scomp -src build\src (tng) (tng)-out build\customerXmlBean.jar schema\customer.xsd
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) -compiler C:\jdk142_04\bin\javac customer.xsdconfig
(tng) (tng) (tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng) (tng) (tng) q个命o(h)行的意思是告诉scomp生成customerXmlBean.jar,攑֜build目录?同时
(tng) (tng) (tng) (tng) (tng) (tng) 生成源代码放在build\src? Schema文g是customer.xsd,xsdconfig文g是customer.xsdconfig.
(tng) (tng) (tng) (tng) (tng) (tng) 其实, 生成的Java源代码没有多大作?我们要的是jar文g.我们先看一下build\src\sample\xmlbean下生成的Classes.
(tng) (tng) (tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)CustomersDocument.java (tng) (tng) (tng) (tng)-- 整个XML文档的Java Class映射
(tng) (tng) (tng) (tng) (tng) (tng) CustomerType.java (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)-- 节点sustomer的映?br /> (tng) (tng) (tng) (tng) (tng) (tng) AddressType.java (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) -- 节点address的映?br /> (tng) (tng) (tng) (tng) (tng) (tng) BillingAddressType.java (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)-- 节点billingAddress的映?br /> (tng) (tng) (tng) (tng) (tng) (tng) PrimaryAddressType.java (tng) (tng) (tng) (tng) (tng) (tng)-- 节点primaryAddress的映?br /> (tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng) (tng) (tng) 好了(jin),到此我们所有的准备工作已经完成? 下面开始进入重点：(x)利用刚才生成的jar文gdXML.
五、利用XMLBean读XML文g

(tng) (tng) (tng) (tng)怎么?是不是很L? XMLBean的威?
六、利用XMLBean写XML文g
(tng) (tng) (tng) (tng)利用XMLBean创徏一个XML文档也是一件轻而易丄?我们再增加一个Method,
(tng) (tng) (tng) (tng)L(fng)一下的Java Class:
(tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng)public void createCustomer() {
(tng) (tng) (tng) (tng)try {
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)// Create Document

(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)// set customer info
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)customer.setId(3);
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)customer.setFirstname("Jessica");
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)customer.setLastname("Lim");
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)customer.setGender("female");
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)customer.setPhoneNumber("1234567");
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)// Add new address
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)AddressType address = customer.addNewAddress();
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)// Add new PrimaryAddress
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)PrimaryAddressType primaryAddress = address.addNewPrimaryAddress();
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)primaryAddress.setPostalCode("350106");
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)primaryAddress.setAddressLine1("#25-1");
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)primaryAddress.setAddressLine2("SHINSAYAMA 2-CHOME");
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)// Add new BillingAddress
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)BillingAddressType billingAddress = address.addNewBillingAddress();
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)billingAddress.setReceiver("Ms Danielle");
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)billingAddress.setPostalCode("350107");
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)billingAddress.setAddressLine1("#167");

(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)File xmlFile = new File(filename);
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)doc.save(xmlFile);
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)} catch (Exception ex) {
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)ex.printStackTrace();
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)}
(tng) (tng)}
(tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng)修改main method.
(tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng)public static void main(String[] args) {
(tng) (tng) (tng) (tng)String filename = "F://JavaTest//Eclipse//XMLBean//xml//customers_new.xml";

(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)customerXMLBean.createCustomer();
(tng) (tng) (tng) (tng)}
(tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng)q行,打开customers_new.xml:

七、利用XMLBean修改XML文g
(tng) (tng) (tng) (tng)我们再增加一个Method:
(tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng) (tng) (tng)public void updateCustomer(int id,String lastname) {
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) try {
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)File xmlFile = new File(filename);
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)CustomersDocument doc = CustomersDocument.Factory.parse(xmlFile);
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)CustomerType[] customers = doc.getCustomers().getCustomerArray();
(tng) (tng) (tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)for (int i = 0; i < customers.length; i++) {
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) CustomerType customer = customers[i];
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)if(customer.getId()==id){
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)customer.setLastname(lastname);
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)break;
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)}
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)}
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)doc.save(xmlFile);
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) } catch (Exception ex) {
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)ex.printStackTrace();
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) }
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)}
(tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng)main method:
(tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng)public static void main(String[] args) {
(tng) (tng) (tng) (tng) String filename = "F://JavaTest//Eclipse//XMLBean//xml//customers_new.xml";
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng)CustomerXMLBean customerXMLBean = new CustomerXMLBean(filename);
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng)customerXMLBean.updateCustomer(3,"last");
(tng) (tng) (tng) (tng)}
(tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng)q行之后,我们会(x)看到客户~号?的客L(fng)lastname已经改ؓ(f)last.
八、利用XMLBean删除一个customer
(tng) (tng) (tng) (tng)再增加一个Method:
(tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng)public void deleteCustomer(int id) {
(tng) (tng) (tng) (tng) try {
(tng) (tng) (tng) (tng) (tng) (tng)File xmlFile = new File(filename);
(tng) (tng) (tng) (tng) CustomersDocument doc = CustomersDocument.Factory.parse(xmlFile);
(tng) (tng) (tng) (tng)CustomerType[] customers = doc.getCustomers().getCustomerArray();
(tng) (tng) for (int i = 0; i < customers.length; i++) {
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)CustomerType customer = customers[i];
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)if(customer.getId()==id){
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)customer.setNil() ;
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)break;
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) }
(tng) (tng) }
(tng) (tng) doc.save(xmlFile);
(tng) (tng) } catch (Exception ex) {
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)ex.printStackTrace();
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)}
(tng) (tng) }
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) main method:
(tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng)public static void main(String[] args) {
(tng) (tng) (tng) (tng)String filename = "F://JavaTest//Eclipse//XMLBean//xml//customers_new.xml";
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng)CustomerXMLBean customerXMLBean = new CustomerXMLBean(filename);
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)
(tng) (tng) (tng) (tng)customerXMLBean.deleteCustomer(3);
(tng) (tng) (tng) (tng)}
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng)
q行,我们会(x)看到客户~号?的客L(fng)资料已经被删?
?ji)、查询XML
(tng) (tng) (tng) (tng)除了(jin)本文在以上讲q的,利用XMLBean能轻L村֮成XML的读写操作外,l合XPath和XQuery,
(tng) (tng) XMLBeanq能完成象SQL查询数据库一h便地查询XML数据. 关于XML查询以及(qing)如何创徏XML数据? 我将在另一文章里讨论.
十、结束语
(tng) (tng) (tng) (tng)XMLBean能帮助我们轻易读写XML,q将有助于我们降低XML的学?fn)和使?有了(jin)q个基础,
