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

Recently, I have been pondering maven. I have shown an example on the Internet. An error was reported during junit testing. The error message is as follows:

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to read candidate component class: file [D:\workspace\MAVEN\example_1\target\classes\cn\springmvc\service\impl\UserServiceImpl.class]; nested exception is org.springframework.core.NestedIOException: ASM ClassReader failed to parse class

A bit of search, the omnipotent stackoverflow, haha, the explanation provided by the foreign colleagues:

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.

The general meaning is that Java 1.8 only supports spring4.0 and later versions, and it is OK to change the sping version in pom to 4.1.5 immediately. You can also reduce the jdk.
