Spring Oxm 简明教程

Spring OXM - Quick Guide

Spring OXM - Overview

Spring 框架使用全局 marshall/unmarshall 接口提供对象/XML 或 O/X 映射，并允许轻松切换 O/X 映射框架。将对象转换为 XML 的此过程称为 XML 编组/序列化，而将 XML 转换为对象的过程称为 XML 解编组/反序列化。

Spring 框架提供了一个 Marshall 和 UnMarshaller 接口，其中 Marshall 接口负责将对象编组到 XML，而 UnMarshaller 接口将 xml 反序列化到一个对象。以下是使用 Spring OXM 框架的主要优点。

Easy Configuration − 通过使用 spring bean context 工厂，创建 marshall/unmarshall 非常容易，并且可配置，而无需担心 O/X 库结构，如 JAXB Context、JiBX binding 工厂等。marshall/unmarshall 可配置为任何其他 bean。
Consistent Interfacing − Marshall 和 UnMarshaller 是全局接口。这些接口提供了一个对其他 O/X 映射框架抽象的层，并允许在它们之间切换，而无需更改代码或进行少量代码更改。
Consistent Exception Handling − 所有底层异常都映射到 XmlMappingException 作为根异常。因此，开发人员不必担心底层 O/X 映射工具自己的异常层次结构。

Marshaller

Marshaller 是一个具有单个方法 marshal 的接口。

public interface Marshaller {
   /**
      * Marshals the object graph with the given root into the provided Result.
   */
   void marshal(Object graph, Result result)
      throws XmlMappingException, IOException;
}

其中 graph 是要编组的任意对象，而 result 是表示 XML 输出的标记接口。以下是可用类型−

javax.xml.transform.dom.DOMResult − Represents org.w3c.dom.Node.
javax.xml.transform.sax.SAXResult − Represents org.xml.sax.ContentHandler.
javax.xml.transform.stream.StreamResult − 表示 java.io.File、java.io.OutputStream 或 java.io.Writer。

UnMarshaller

UnMarshaller 是一个具有单个方法 unmarshal 的接口。

public interface UnMarshaller {
   /**
      * Unmarshals the given provided Source into an object graph.
   */
   Object unmarshal(Source source)
      throws XmlMappingException, IOException;
}

其中 source 是用于表示 XML 输入的标记化界面。以下是可用的类型：

javax.xml.transform.dom.DOMSource − Represents org.w3c.dom.Node.
javax.xml.transform.sax.SAXSource − 表示 org.xml.sax.InputSource 和 org.xml.sax.XMLReader。
javax.xml.transform.stream.StreamSource − 表示 java.io.File、java.io.InputStream 或 java.io.Reader。

Spring OXM - Environment Setup

本章将在您开始使用 Spring 框架时，指导您如何准备开发环境。它还将教您在设置 Spring 框架之前如何在您的机器上设置 JDK、Maven 和 Eclipse −

Setup Java Development Kit (JDK)

你可以从 Oracle 的 Java 站点下载 SDK 的最新版本 − Java SE Downloads. 你在下载文件中可以找到安装 JDK 的说明，按照给定的说明进行安装和配置。最后设置 PATH 和 JAVA_HOME 环境变量以引用包含 java 和 javac 的目录，通常分别为 java_install_dir/bin 和 java_install_dir。

如果您运行的是 Windows 且在 C:\jdk-11.0.11 中安装了 JDK，那么您将不得不把以下代码行放入您的 C:\autoexec.bat 文件中。

set PATH=C:\jdk-11.0.11;%PATH%
set JAVA_HOME=C:\jdk-11.0.11

或者，在 Windows NT/2000/XP 中，你必须右键单击我的电脑，选择属性 → 高级 → 环境变量。然后，你将不得不更新 PATH 值并单击确定按钮。

在 Unix（Solaris、Linux 等）中，如果 SDK 安装在 /usr/local/jdk-11.0.11 且您使用 C shell，那么您将不得不把以下代码行放入您的 .cshrc 文件中。

setenv PATH /usr/local/jdk-11.0.11/bin:$PATH
setenv JAVA_HOME /usr/local/jdk-11.0.11

或者，如果你使用诸如 Borland JBuilder、Eclipse、IntelliJ IDEA 或 Sun ONE Studio 这样的集成开发环境 (IDE)，则必须编译并运行一个简单程序来确认 IDE 知道你在何处安装了 Java。否则，你必须按照 IDE 文档中给出的内容执行正确的设置。

Setup Eclipse IDE

本教程中的所有示例都是使用 Eclipse IDE 编写的。因此，我们建议你应该在你机器上安装 Eclipse 的最新版本。

要安装 Eclipse IDE，请从 www.eclipse.org/downloads 下载最新的 Eclipse 二进制文件。下载安装文件后，将二进制分发包解压到方便的位置。例如，在 Windows 上的 C:\eclipse 中，或 Linux/Unix 上的 /usr/local/eclipse 中，最后相应地设置 PATH 变量。

可以通过在 Windows 机器上执行以下命令启动 Eclipse，或者你只需双击 eclipse.exe

%C:\eclipse\eclipse.exe

可以通过在 Unix（Solaris、Linux 等）机器上执行以下命令启动 Eclipse −

$/usr/local/eclipse/eclipse

成功启动后，如果一切正常，它应该显示以下结果 −

Set Maven

在本教程中，我们使用 maven 来运行和构建基于 Spring 的示例。请按照 Maven - Environment Setup 安装 maven。

Spring OXM - Create Project

在 Eclipse 中，选择 File → New → Maven Project 。勾选 *创建简单项目（跳过原型选择）*并单击下一步。

按照以下所示输入详细信息 −

groupId − com.tutorialspoint
artifactId − springoxm
version − 0.0.1-SNAPSHOT
name − Spring OXM
description − Spring OXM 项目

单击完成按钮，将创建一个新项目。

pom.xml

您可以查看 pom.xml 的默认内容

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

   <artifactId>springoxm</artifactId>
   <version>0.0.1-SNAPSHOT</version>
   <name>Spring OXM</name>
   <description>Spring OXM Project</description>
</project>

现在我们的项目已经准备就绪，在下一章中，让我们在 pom.xml 中添加以下依赖项。

Spring Core
Spring OXM
JAXB

Spring OXM - Update Project JAXB2

按照下面所示更新 pom.xml 的内容，使其包含 Spring core、Spring oxm 和 jaxb 依赖项：

按照下面所示使用 O/X 注解创建 Student.java 类。

Student.java

package com.tutorialspoint.oxm.model;

import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class Student{
   String name;
   int age;
   int id;

   public String getName(){
      return name;
   }
   @XmlElement
   public void setName(String name){
      this.name = name;
   }
   public int getAge(){
      return age;
   }
   @XmlElement
   public void setAge(int age){
      this.age = age;
   }
   public int getId(){
      return id;
   }
   @XmlAttribute
   public void setId(int id){
      this.id = id;
   }
}

在 *src → main → resources * 中创建 applicationcontext.xml，其内容如下。

applicationcontext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

   <oxm:jaxb2-marshaller id="jaxbMarshaller">
      <oxm:class-to-be-bound name="com.tutorialspoint.oxm.model.Student"/>
   </oxm:jaxb2-marshaller>
</beans>

Spring OXM - Test JAXB2

使用 marshall 和 unmarshall 对象创建主类 OXMApplication.java 。此类的目的是使用 marshall 对象将学生对象编组到 student.xml，然后使用 unmarshall 对象将 student.xml 解编组到 student 对象。

Example

OXMApplication.java

package com.tutorialspoint.oxm;

import java.io.FileInputStream;
import java.io.FileWriter;
import java.io.IOException;
import javax.xml.transform.stream.StreamResult;
import javax.xml.transform.stream.StreamSource;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.oxm.Marshaller;
import org.springframework.oxm.Unmarshaller;
import org.springframework.oxm.XmlMappingException;
import com.tutorialspoint.oxm.model.Student;

public class OXMApplication {
   public static void main(String[] args) {
      ApplicationContext context = new ClassPathXmlApplicationContext("applicationcontext.xml");
      Marshaller marshaller = (Marshaller)context.getBean("jaxbMarshaller");
      Unmarshaller unmarshaller = (Unmarshaller)context.getBean("jaxbMarshaller");

      // create student object
      Student student = new Student();
      student.setAge(14);
      student.setName("Soniya");

      try {
         marshaller.marshal(student, new StreamResult(new FileWriter("student.xml")));
         System.out.println("Student marshalled successfully.");
         FileInputStream is =  new FileInputStream("student.xml");
         Student student1 = (Student)unmarshaller.unmarshal(new StreamSource(is));
         System.out.println("Age: " + student1.getAge() + ", Name: " + student1.getName());
      } catch(IOException | XmlMappingException ex) {
         ex.printStackTrace();
      }
   }
}

Output

在 Eclipse 中的文件内容区中单击鼠标右键，然后选择 Run as java application 并验证输出。

package com.tutorialspoint.oxm.model;

public class Student {
   String name;
   int age;
   int id;

   public String getName(){
      return name;

在 src → main → resources * 文件夹中添加一个 castor 映射所需的映射 xml，以便将 *Student 类映射为 mappings.xml ，如下所示：

mappings.xml

<?xml version="1.0"?>
<!DOCTYPE mapping PUBLIC "-//EXOLAB/Castor Mapping DTD Version 1.0//EN" "http://castor.org/mapping.dtd">
