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
Jibx插件的使用

Order类
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; } public Customer getCustomer() { return customer; } public void setCustomer(Customer customer) { this.customer = customer; } public Address getBillTo() { return billTo; } public void setBillTo(Address billTo) { this.billTo = billTo; } public Shipping getShipping() { return shipping; } public void setShipping(Shipping shipping) { this.shipping = shipping; } public Address getShipTo() { return shipTo; } public void setShipTo(Address shipTo) { this.shipTo = shipTo; } public Float getTotal() { return total; } public void setTotal(Float total) { this.total = total; } /* * (non-Javadoc) * * @see java.lang.Object#toString() */ @Override public String toString() { return "Order [orderNumber=" + orderNumber + ", customer=" + customer + ", billTo=" + billTo + ", shipping=" + shipping.toString() + ", shipTo=" + shipTo + ", total=" + total + "]"; } }
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
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:
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> <!-- 生成jibx class信息 --> <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> <!-- 把jibx绑定到了comile编译阶段 --> <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。
