问题
Springmvc 编译运行时出现如下异常
Caused by: org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [D:\***.class]; nested exception is org.springframework.core.NestedIOException: ASM ClassReader failed to parse class file - probably due to a new Java class file version that isn't supported yet ...
这个一般是升级了jdk版本后，导致低版本的springframework框架有些类不被jdk支持。如jdk1.6改成1.8后，spring 3x有些类会报错。
解决方案
在pom.xml中将springframework 3.x升级为5.x，问题解决。
