如何使用javac正确编译这个文件

Question

我有以下名为 Test.Java 的文件，其代码是

package example25;

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;

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

}//end class

这是我尝试编译此文件的方式以及我得到的输出

测试使用的所有类文件都出现在它旁边并且已经正确编译。 测试是最后一个给我带来麻烦的文件。此外，测试中使用的一些类存在于 C:\jibx\lib> 中，而不是我执行命令的 C:\jibx utorial> 中。任何有关我如何在不修改之前生成的类文件的情况下解决此问题的建议将不胜感激。

Answer 1

将目录 C:\jibx\lib 添加到类路径，例如

SET CLASSPATH=%CLASSPATH%;C:\jibx\lib;.

然后执行javac

Answer 2

由于存在一些导入错误，请按照 Satya 的说法正确设置类路径，并且您当前的类位于某个目录中，您应该使用 javac 的 -d 属性来编译它 如下图

javac -d 。你的文件名.java
