春季食谱预订：AOP问题

正在阅读春季食谱和尝试一些AOP相关的东西。解释似乎很不错，当我试图运行的例子，我得到了以下错误：我只是想运行示例代码，完全没有改变。任何想法我可能会失踪？（我加入通用日志/ aspectjrt.jar和aspectjweaver.jar到我的类路径）春季食谱预订：AOP问题

的异常已经说，你的问题是什么：

的ClassLoader [sun.misc.Launcher $ AppClassLoader]不提供 'addTransformer（ClassFileTransformer）'方法。指定定制的LoadTimeWeaver或使用Spring的代理启动Java虚拟机： -javaagent：org.springframework.instrument.jar

尝试的命令行选项。

-javaagent：C：\ springjars \ spring \ spring-framework-3.1.0.M2 \ dist \ org.springframework.instrument-3.1.0.M2.jar。这工作得很好。谢谢。 –
