我成功地绑定了通过 XSD 生成的文件,并且在我的目录中得到了以下文件

C:\jibx\tutorial\example25>dir
Volume in drive C is WINDOWS
Volume Serial Number is 1C8F-663E

Directory of C:\jibx\tutorial\example25

现在我将这些文件复制到 Eclipse 中新创建的 JAVA 项目中,在该项目中创建了一个名为 example25 的包并将这些文件粘贴到那里,然后我使用以下代码并在调试模式下运行它

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.util.Iterator;

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 example25.*;


public class Test
{

public static void main(String[] args)
{

        try
        {

            // unmarshal customer information from file
            IBindingFactory bfact = BindingDirectory.getFactory(Order.class);
            IUnmarshallingContext uctx = bfact.createUnmarshallingContext();
            FileInputStream in = new FileInputStream("D:\\Java Libraries\\jibx\\dwcode2\\starter.xml");
            Order order = (Order)uctx.unmarshalDocument(in, null);

            // compute the total amount of the order
            float total = 0.0f;
            for (Iterator<Item> iter = order.getItemList().iterator(); iter.hasNext();)
            {
                Item item = iter.next();
                total += item.getPrice() * item.getQuantity();
            }
            order.setTotal(new Float(total));

            // marshal object back out to file (with nice indentation, as UTF-8)
            IMarshallingContext mctx = bfact.createMarshallingContext();
            mctx.setIndent(2);
            FileOutputStream out = new FileOutputStream("c:\\out.xml");
            mctx.setOutput(out, null);
            mctx.marshalDocument(order);
            System.out.println("Processed order with " +  order.getItemList().size() + " items and total value " + total);

        }
        catch (FileNotFoundException e)
        {
            e.printStackTrace();
            System.exit(1);
        } catch (JiBXException e)
        {
            e.printStackTrace();
            System.exit(1);
        }
    }

}//end main

执行第一条语句后出现以下错误

Unable to access binding information for class example25.Order
Make sure the binding has been compiled
java.lang.NoSuchFieldException: JiBX_bindingList
at java.lang.Class.getDeclaredField(Unknown Source)
at org.jibx.runtime.BindingDirectory.getBindingList(BindingDirectory.java:68)

拉杰什,

您在该目录中显示的文件意味着您正确执行了所有操作!

您犯的错误是使用eclipse,因为eclipse会再次自动编译源代码文件(没有您在绑定步骤中添加的绑定信息)

尝试使用您在第一步中生成的类文件运行 Test.class 文件。

你的 java 命令应该是这样的:

java -cp C:\directorywithtestclass;C:\jibx\tutorial Test

由于 JiBX Binding 编译器修改生成的类文件并使用 binding.xml 放入绑定信息,因此我们需要使用Binding 编译器将生成的 .java 文件和 binding.xml 生成类文件。要使用 eclipse 来执行此操作,我们可以按照此链接中的说明使用。
