Jibx是一款非常优秀的XML文件数据绑定的框架，提供灵活的绑定映射文件，实现数据对象和XML文件之间的转换，并不需要修改既有的Java，另外，它的转换效率是目前很多其他开源项目都无法比拟的。本文来演示下如何使用

package com.dpb.netty.xml.pojo;
    
    /** * * @author 波波烤鸭 * @email dengpbs@163.com * */
    public class Order { 
    
        private long orderNumber;
    
        private Customer customer; 
    
        /** Billing address information. */
        private Address billTo;
    
        private Shipping shipping;
    
        /** * Shipping address information. If missing, the billing address is also * used as the shipping address. */
        private Address shipTo;
    
        private Float total;
    
        public long getOrderNumber() { 
    	return orderNumber;
        }
    
        public void setOrderNumber(long orderId) { 
    	this.orderNumber = orderId;

        @Override
        public String toString() {

## 生成绑定文件 ##

我们想将绑定文件生成在src/main/resources/jibx目录下，进入cmd下，**切换到maven项目的target/classes**目录下

![在这里插入图片描述][20190413232059737.png]  
然后执行如下命令

java -cp c:\tools\工具\jibx_1_3_1\jibx\lib\jibx-tools.jar org.jibx.binding.generator.BindGen -t C:\tools\workspace\workspace-csdn\NettyLearn\src\main\resources\jibx -v  com.dpb.netty.xml.pojo.Customer com.dpb.netty.xml.pojo.Shipping com.dpb.netty.xml.pojo.Address com.dpb.netty.xml.pojo.Order com.dpb.netty.xml.pojo.OrderFactory

说明

java -cp ..libx-tools.jar ..BindGen -t 生成文件保存地址 -v 需要绑定文件的class文件 完整包名.类名

## 对字节码增强 ##

### 方式1:jibx-bind.jar增强 ###

**未增强前**:

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9kcGItYm9ib2thb3lhLXNtLmJsb2cuY3Nkbi5uZXQ_size_16_color_FFFFFF_t_70 3]

**执行如下命令**:

java -cp c:\tools\工具\jibx_1_3_1\jibx\lib\jibx-bind.jar org.jibx.binding.Compile -v C:\tools\workspace\workspace-csdn\NettyLearn\src\main\resources\jibx\binding.xml

### 方式2:maven插件动态增强 ###

在maven项目中如果能够通过插件动态的增强，那么实现起来就比较方便，实现步骤如下:

<dependency>
    	<groupId>org.jibx</groupId>
    	<artifactId>jibx-run</artifactId>
    	<version>1.3.1</version>
    </dependency>
    <dependency>
    	<groupId>org.jibx</groupId>
    	<artifactId>jibx-extras</artifactId>
    	<version>1.3.1</version>
    </dependency>
    
    <build>
    	<plugins>
    		<plugin>
    			
    			<groupId>org.jibx</groupId>
    			<artifactId>jibx-maven-plugin</artifactId>
    			<version>1.3.1</version>
    			<configuration>
    				<schemaBindingDirectory>${basedir}/src/main/resources/jibx</schemaBindingDirectory>
    				<includeSchemaBindings>
    					<includeSchemaBindings>*binding.xml</includeSchemaBindings>
    				</includeSchemaBindings>
    				<verbose>true</verbose>
    			</configuration>
    			<executions>
    				<execution>
    					<id>jibx-bind</id>
    					<phase>compile</phase>
    					
    					<goals>
    						<goal>bind</goal>
    					</goals>
    				</execution>
    			</executions>
    		</plugin>
    	</plugins>
    </build>

执行install即可增强class文件

## 测试 ##

执行如下测试代码

package com.dpb.netty.xml;
    
    import java.io.IOException;
    import java.io.StringReader;
    import java.io.StringWriter;
    
    import org.jibx.runtime.BindingDirectory;
    import org.jibx.runtime.IBindingFactory;
    import org.jibx.runtime.IMarshallingContext;
    import org.jibx.runtime.IUnmarshallingContext;
    import org.jibx.runtime.JiBXException;
    
    import com.dpb.netty.xml.pojo.Order;
    import com.dpb.netty.xml.pojo.OrderFactory;
    
    public class TestOrder { 
    	private IBindingFactory factory = null;
    	private StringWriter writer = null;
    	private StringReader reader = null;
    	private final static String CHARSET_NAME = "UTF-8";
    
    	private String encode2Xml(Order order) throws JiBXException, IOException { 
    		factory = BindingDirectory.getFactory(Order.class);
    		writer = new StringWriter();
    		IMarshallingContext mctx = factory.createMarshallingContext();
    		mctx.setIndent(2);
    		mctx.marshalDocument(order, CHARSET_NAME, null, writer);
    		String xmlStr = writer.toString();
    		writer.close();
    		System.out.println(xmlStr.toString());
    		return xmlStr;
    	}
    
    	private Order decode2Order(String xmlBody) throws JiBXException { 
    		reader = new StringReader(xmlBody);
    		IUnmarshallingContext uctx = factory.createUnmarshallingContext();
    		Order order = (Order) uctx.unmarshalDocument(reader);
    		return order;
    	}
    
    	public static void main(String[] args) throws JiBXException, IOException { 
    		TestOrder test = new TestOrder();
    		Order order = OrderFactory.create(123);
    		String body = test.encode2Xml(order);
    		Order order2 = test.decode2Order(body);
    		System.out.println(order2);
    	}
    }

XML的序列化和反序列执行成功。
