2. 利用scomp来生成Java Classes
scomp是XMLBean提供的一个编译工具,它在bin的目录下. 通过这个工具,我们可以将以上的Schema文件生成Java Classes.scomp的语法如下:-
scomp [options] [dirs]* [schemaFile.xsd]* [service.wsdl]* [config.xsdconfig]*
主要参数说明:
-src [dir] -- 生成的Java Classes存放目录
-srconly -- 不编译Java Classes,不产生Jar文件
-out [jarFileName] -- 生成的Jar文件,缺省是xmltypes.jar
-compiler -- Java编译器的路径,即Javac的位置
schemaFile.xsd -- XML Schema文件位置
config.xsdconfig -- xsdconfig文件的位置, 这个文件主要用来制定生成的Java Class的一些文件名规则和Package的名称,在本文,package是sample.xmlbean
在本文,我是这样运行的:
scomp -src build\src -out build\customerXmlBean.jar schema\customer.xsd
-compiler C:\jdk142_04\bin\javac customer.xsdconfig
这个命令行的意思是告诉scomp生成customerXmlBean.jar,放在build目录下,同时生成源代码放在build\src下, Schema文件是customer.xsd,xsdconfig文件是customer.xsdconfig.其实, 生成的Java源代码没有多大作用,我们要的是jar文件.我们先看一下build\src\sample\xmlbean下生成的Classes.
CustomersDocument.java -- 整个XML文档的Java Class映射
CustomerType.java -- 节点sustomer的映射
AddressType.java -- 节点address的映射
BillingAddressType.java -- 节点billingAddress的映射
PrimaryAddressType.java -- 节点primaryAddress的映射
好了,到此我们所有的准备工作已经完成了. 下面就开始进入重点:利用刚才生成的jar文件读写XML.
五、利用XMLBean读XML文件
新建一个Java Project,将XMLBean2.0.0\lib\下的Jar文件和刚才我们生成的customerXmlBean.jar加入到Project的ClassPath.
新建一个Java Class: CustomerXMLBean. 源码如下:
package com.sample.reader;
import java.io.File;
import sample.xmlbean.*;
import org.apache.commons.beanutils.BeanUtils;
import org.apache.xmlbeans.XmlOptions;
public class CustomerXMLBean {
private String filename = null;
public CustomerXMLBean(String filename) {
super();
this.filename = filename;
}
public void customerReader() {
try {
File xmlFile = new File(filename);
CustomersDocument doc = CustomersDocument.Factory.parse(xmlFile);
CustomerType[] customers = doc.getCustomers().getCustomerArray();
for (int i = 0; i < customers.length; i++) {
CustomerType customer = customers[i];
println("Customer#" + i);
println("Customer ID:" + customer.getId());
println("First name:" + customer.getFirstname());
println("Last name:" + customer.getLastname());
println("Gender:" + customer.getGender());
println("PhoneNumber:" + customer.getPhoneNumber());
// Primary address
PrimaryAddressType primaryAddress = customer.getAddress().getPrimaryAddress();
println("PrimaryAddress:");
println("PostalCode:" + primaryAddress.getPostalCode());
println("AddressLine1:" + primaryAddress.getAddressLine1());
println("AddressLine2:" + primaryAddress.getAddressLine2());
// Billing address
BillingAddressType billingAddress = customer.getAddress().getBillingAddress();
println("BillingAddress:");
println("Receiver:" + billingAddress.getReceiver());
println("PostalCode:" + billingAddress.getPostalCode());
println("AddressLine1:" + billingAddress.getAddressLine1());
println("AddressLine2:" + billingAddress.getAddressLine2());
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
private void println(String str) {
System.out.println(str);
}
public static void main(String[] args) {
String filename = "F://JavaTest//Eclipse//XMLBean//xml//customers.xml";
CustomerXMLBean customerXMLBean = new CustomerXMLBean(filename);
customerXMLBean.customerReader();
}
