java - 使用 Javac 编译困难 - 问题

Question

我有以下目录结构 c:\jibx\tutorial\example23\ 示例23包含以下文件

现在我正在尝试仅编译引用此文件夹中其他类的 CustomerManager java 文件。CustomerManager java 文件的代码很简单

package example23;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import org.jibx.runtime.*;

public class CustomerManager 
{

                 public CustomerManager()
                 {
            try 
            {
            IBindingFactory bfact = BindingDirectory.getFactory(Customer.class);
            IUnmarshallingContext uctx = bfact.createUnmarshallingContext();

            Object obj = uctx.unmarshalDocument(new FileInputStream("C:/jibx/tutorial/example23/customer.xml"), null);
            Customer customer = (Customer)obj;
            System.out.print(customer.street+", "+customer.city);
            IMarshallingContext mctx = bfact.createMarshallingContext();
            mctx.setIndent(4);
            mctx.marshalDocument(obj, "UTF-8", null, new FileOutputStream("C:/jibx/tutorial/example23/customer2.xml"));
            } 
            catch (FileNotFoundException e) 
            {
            e.printStackTrace();
            } 
            catch (JiBXException e) 
            { 
            e.printStackTrace();
            }
                  }   //end method

 public static void main(String[] args) 
 {
 new CustomerManager();
 }

 }//end class

现在此文件包含对其顶层目录中文件的引用，例如 c:\jibx\lib（文件本身位于 c:\jibx\tutorial\example23 中）

我尝试了以下方法来引用这些库并编译文件

C:\jibx\tutorial>javac  -classpath c:\jibx\lib\  example23\CustomerManager.java

and the output i got was
example23\CustomerManager.java:7: error: package org.jibx.runtime does not exist

关于我如何解决这个问题的任何建议？

Answer 1

我认为您的问题在于以下行

-classpath c:\jibx\lib\

此目录是否包含 jar 文件？

在这种情况下，您可以尝试使用这样的 glob：

-classpath c:\jibx\lib\*.jar

这样，您将在类路径的 c:\jibx\lib\ 目录中包含所有 jar 文件。

Answer 2

您必须在类路径中添加 .jar 文件。

例如，

javac  -cp .;c:\jibx\lib\your_lib.jar  example23\CustomerManager.java

Answer 3

我设法通过以下方式解决了这个问题：

C:\jibx\tutorial>javac  -cp .\example23\*;.;.;c:\jibx\lib\jibx-run.jar;  .\example23\CustomerManager.java

谢谢你的好建议
