Question

`我正在尝试对 Maven ， Spring ， Spring MVC ， JPA 进行基本配置hibernate，c3p0，MySql和Jetty服务器一旦启动服务器我就得到了

ClassNotFoundException org.springframework.objenesis.ObjenesisException，

但我也添加了“objenesis-1.2”依赖，因为我看到了net的解决方案。

Answer 1

这是嵌入在Spring中的Objenesis版本。所以你不需要实际的Objenesis jar。这通常是春天的核心。

在您的情况下，我认为您的弹簧罐之间存在不兼容性。最简单的解决方案可能是将所有内容升级到最新的spring版本。

Answer 2

请确保jar位于服务器的引导类路径中。这通常是服务器的 lib或endorsed目录，而不是您的应用程序的WEB-INF/lib目录。

看看是否能解决您的问题。

希望这有帮助！
