Caused by: org.springframework.core.NestedIOException: ASM ClassReader failed to parse class file

最近在琢磨maven，自己照着网上的例子塔了一个例子，在junit测试时报错了，详细错误信息：

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [D:workspaceMAVENexample_1	argetclassescnspringmvcserviceimplUserServiceImpl.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: file [D:workspaceMAVENexample_1	argetclassescnspringmvcserviceimplUserServiceImpl.class]; nested exception is java.lang.IllegalArgumentException

一点点搜吧，万能的stackoverflow啊，哈哈，老外同仁给出的解释：

Note that the Java 8 bytecode level (-target 1.8, as required by -source 1.8) is only fully supported as of Spring Framework 4.0. In particular, Spring 3.2 based applications need to be compiled with a maximum of Java 7 as the target, even if they happen to be deployed onto a Java 8 runtime. Please upgrade to Spring 4 for Java 8 based applications.

大概的意思就是java1.8版本只支持spring4.0以上，立马把pom里的sping版本换4.1.5就ok了，也可以把jdk调低点。
