初始SessionFactory创建失败.java.lang.NoClassDefFoundError:org/hiber nate/cfg/Configuration

Question

我在Eclipse中创建了一个项目并成功执行它(这是一个普通的项目,没有Maven或Beans,非常简单),我用项目创建了一个.jar并尝试执行它,但它抛出了以下错误:

C:\Documents\wrapper-windows-x86-64-3.5.19-st\bin>java -cp QuoteHandler.jar stoc

该项目的.classpath文件具有:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry kind="src" path="src"/>
    <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/jre7"/>

    <classpathentry kind="lib" path="lib/c3p0-0.9.1.jar"/>
    <classpathentry kind="output" path="bin"/>
</classpath>

检查Internet我将%CLASSPATH%变量修改为:

CLASSPATH = C:\Program Files\Java\jre7\lib;C:\Program Files\Java\jre7\lib\c3p0-0.9.1.jar

所有引用都在项目的构建路径中进行了很好的配置,并且它可以工作,但是当我执行.jar时它不起作用(所有引用都包含在jar中).我错过了什么？

Answer 1

尝试 Eclipse 中的以下选项：

1. 文件->导出
2. 从向导中选择 Java->Runnable JAR file
3. 点击下一步
4. 选择启动配置：选择具有 main() 方法的类，如果此处不可用，则尝试在 eclipse 中运行您的程序
5. 导出目标：选择 jar 文件的完整路径
6. 库处理：选择第三个“复制所需的库...”
7. 点击完成

转到命令提示符并将目录更改为导出的 jar 文件并输入 java -jar <exported_jar>.jar

需要注意的是：在 java 中，类路径 lib/* 无法解析目录中的所有 jar，您必须手动键入每个 jar 条目。
