3. 问题分析
“ASM ClassReader failed to parse class file”是其中主要的原因。检查Maven的类库,没有发现问题,无asm显性依赖,其依赖产生于spring本身。故分析有可能是spring本身的 问题造成了;但是这么流行的spring,怎么会出错了,我不能这么牛x碰到这么简单的问题吧?
难道是版本?除了版本之外,spring无大区别。经过一般搜索,网上还真有类似的问题:
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.
所以,看明白了吧,方案有两条:
a. 使用jdk7
b. 升级spring 4
4. 问题解决
最终选择了升级Spring4.1.7, 然后问题解决。
