JAXB出來很長時間了,英文是Java Architecture for XML Binding, JAVA XML 綁定體系結(jié)構(gòu)。

　　主要是做XML與JAVA對象間的轉(zhuǎn)換。不需要編碼，只需要定義好XSD文件，就可以XSD生成JAVA對象文件。讓我們從重體力勞動中解脫出來。

　　關(guān)于這個框架的用法以后再說，先來介紹如何概據(jù)XSD文件檢測XML是否合法。

package com.chouy.jaxb.main;

import java.io.File;

import java.io.FileInputStream;

import javax.xml.XMLConstants;

import javax.xml.transform.Source;

import javax.xml.transform.sax.SAXSource;

import javax.xml.validation.Schema;

import javax.xml.validation.SchemaFactory;

import javax.xml.validation.Validator;

import org.xml.sax.InputSource;

public class XmlValidateByXSD

{

public static void main(String[] args)

{

try

{

// JAXBContext jc = JAXBContext.newInstance(REQUEST.class);

// Unmarshaller unmarshaller = jc.createUnmarshaller();

String schemaLanguage = XMLConstants.W3C_XML_SCHEMA_NS_URI;

SchemaFactory schemaFactory = SchemaFactory.newInstance(schemaLanguage);

Schema schema = schemaFactory.newSchema(new File("E:/zy_share/dev_project/jaxb_training/src/request.xsd"));

// unmarshaller.setSchema(schema);

Validator validator = schema.newValidator();

InputSource inputSource = new InputSource(new FileInputStream(new File("E:/zy_share/dev_project/jaxb_training/request.xml")));

Source source = new SAXSource(inputSource);

validator.validate(source);

System.out.println("success");

}

catch (Exception e)

{

e.printStackTrace();

}

}

}

　　順便說一個XSD文件，它主要是為了解決DTD文件無法精解描述XML和無法完全驗證XML合法性的缺點而制定的。它的好處是用XML文件格式，描述XML文件的格式。
