xmlbeans 2.5.0使用详细说明

xmlbeans有点和hibernate相识，hibernate对数据进行对象化操作，xmlbeans对xml进行对象操作化，很好用，不过很少人用，也可能是对初学者来说比较难入门的原因

先到官网上下载xmlbeans 2.5.0，到apache官网下载，下载只要下载xmlbeans-2.5.0.zip就好

解压，可以看到以下的几个目录：

-bin 常用的命令在这个目录

-lib 一些核心或者用到的JAR

-docs 文档

-samples 示例包括schema和生成后的xml

-schemas 一些schema示例，直接可以拿来打包

注意的地方

schema手写的时候最好在IDE里面写，里面可以告诉你详细的错误信息

从里面拿个示例出来，schemas/easypo.xsd

<xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:po="http://openuri.org/easypo"
targetNamespace="http://openuri.org/easypo"
elementFormDefault="qualified">

<xs:element name="purchase-order">
<xs:complexType>
<xs:sequence>
<xs:element name="customer" type="po:customer"/>
<xs:element name="date" type="xs:dateTime"/>
<xs:element name="line-item" type="po:line-item" minOccurs="0" maxOccurs="unbounded"/>
<xs:element name="shipper" type="po:shipper" minOccurs="0" maxOccurs="1"/>
</xs:sequence>
</xs:complexType>
</xs:element>

<xs:complexType name="customer">
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="address" type="xs:string"/>
</xs:sequence>
<xs:attribute name="age" type="xs:int"/>
<xs:attribute name="moo" type="xs:int" default="100"/>
<xs:attribute name="poo" type="xs:int" fixed="200"/>
</xs:complexType>

<xs:complexType name="line-item">
<xs:sequence>
<xs:element name="description" type="xs:string"/>
<xs:element name="per-unit-ounces" type="xs:decimal"/>
<xs:element name="price" type="xs:decimal"/>
<xs:element name="quantity" type="xs:integer"/>
</xs:sequence>
</xs:complexType>

<xs:complexType name="shipper">
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="per-ounce-rate" type="xs:decimal"/>
</xs:sequence>
</xs:complexType>

</xs:schema>

xmlns:po="http://openuri.org/easypo" //下面的元素引用到的都要以po:属性名命名，也可以写成 xmlns="http://openuri.org/easypo" 则下面的引用元素就不能以po:属性名命名

targetNamespace="http://openuri.org/easypo"//这个是打包的时候的明白规则，可以不用，不用的时候可以在打包的时候加上，通过文件.xsdconfig索引定义的包名，下面有详细介绍

注意：如果这个类似这个schema，生成的xml在子节点位置要有attribute，则在增加，修改的方法不能直接用节点的documentsave，要把它转为String后再通过IO保存该XML数据

打包

schema写好后，到bin下打包，把easypo.xsd和easypo.xsdconfig一起扔到bin下

运行cmd窗口，切换到bin的当前目录，运行命令：

scomp -src easyposrc easypo.xsd easypo.xsdconfig

命令解析：

//-src是生成的src的文件名，该src的文件名为easyposrc

easypo.xsd是要打包的schema

easypo.xsdconfig是命名规则，如果你在schema定义了targetNamespace，那么加上这个easypo.xsdconfig没效，最后生成的xml

文件是以targetNamespace定义的参数为准

下面的是一个写好的示例，注意，这个是另外的一个schema

xml文件

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

操作xml

把jar放到项目下，引入后，其他的操作都和操作对象没什么多大的区别

public class CustomerTest {
// 增加一个顾客
public boolean addCustomer() throws IOException {
boolean bol = false;
CustomersDocument document = CustomersDocument.Factory.newInstance();
document.addNewCustomers().addNewCustomer();
// Create Document
CustomersDocument doc = CustomersDocument.Factory.newInstance();
// Add new customer
CustomerType customer = doc.addNewCustomers().addNewCustomer();
// set customer info
customer.setId(3);
customer.setFirstname("Jessica");

customer.setGender("female");
customer.setPhoneNumber("1234567");
// Add new address
AddressType address = customer.addNewAddress();
// Add new PrimaryAddress

primaryAddress.setPostalCode("350106");
