我已经升级到 Spring 源代码 3.1.0，但我不确定为什么我的项目无法再找到
ReflectiveLoadTimeWeaver
我已确保在我的构建路径中添加服务器运行时库，但我仍然以BeancreationExceptions. 堆栈跟踪：

主要说明它与 RelectiveLoadTimeWeaver 有问题，
Error creating bean with name 'org.springframework.instrument.classloading.ReflectiveLoadTimeWeaver#3834a1c8'
我曾经能够更新我的服务器的 context.xml 并添加 InstrumentalLoadtimeWeaver 加载器，但它不再有效。
<?xml version="1.0" encoding="UTF-8"?>

编辑：完整的堆栈跟踪
