java - 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了它(这是一个普通的项目，没有 Maven 或 Beans，非常简单)，我用该项目创建了一个 .jar 并尝试执行它但是它抛出以下错误:

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

项目的.classpath文件有:

<?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>

网上查了一下我把%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配置好并且可以正常工作，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

当您使用 -cp 运行程序时特别指定类路径时，您会覆盖默认的 CLASSPATH os 变量。

因此您需要将所有需要的类/jar 指定为 -cp 中的列表，或者您需要修改您的 CLASSPATH 以包含您的 jar 目录。这个问题，Setting multiple jars in java classpath , 描述了设置多个类路径元素。
