"ASM ClassReader failed to parse class file" is the main reason. Check Maven's class library, no problems are found, no asm explicit dependencies, and its dependencies are generated by spring itself.
a. Use jdk7
b. Upgrade spring 4
I use jdk1.8 spring to use the demo spring-3.1.12.RELEASE before, and after modifying the spring version to 4.3.12.RELEASE, the problem is solved
