Most likely you have lambda expression inside one of your spring beans. Apparently, spring 3 beans can't initialize if there is a lambda somewhere in their code. In case migration to spring 4 is not an option, try to rewrite your lambda expressions using anonymous classes, like
很可能您的一个 spring bean 中有 lambda 表达式。显然，如果代码中的某个地方存在 lambda，则 spring 3 bean 无法初始化。如果迁移到 spring 4 不是一种选择，请尝试使用匿名类重写 lambda 表达式，例如
Function<A,B> lambda = new Function() {
public B apply(A s) { ... }
}
or move lambda code out of the spring bean. I had the same issue and it helped me, I could still use spring 3 with jre/jdk 8.
或者将 lambda 代码移出 spring bean。我遇到了同样的问题，它对我有帮助，我仍然可以将 spring 3 与 jre/jdk 8 一起使用。

You have not stated which JDK you are using. If you are using 1.8 then you might find that you will need to upgrade Spring to 4 (or 3.2.9+ as yurez has pointed out).
您没有说明您使用的是哪个 JDK。如果您使用的是 1.8，那么您可能会发现需要将 Spring 升级到 4（或 yurez 指出的 3.2.9+）。
See the answer to this question: Java 1.8 ASM ClassReader failed to parse class file - probably due to a new Java class file version that isn't supported yet
请参阅此问题的答案： Java 1.8 ASM ClassReader failed to parse class file - 可能是由于尚不支持新的 Java 类文件版本

The problem is the location of your xml file. WEB-INF is not part of the classpath. Try copying it under the "src" folder.
问题是您的 xml 文件的位置。WEB-INF 不是类路径的一部分。尝试将其复制到“src”文件夹下。
回答by Atul
Try putting the file under src folder. It will be then copied to the WEB-INF/classesfolder. Then you can refer to it as classpath:dispatcher-servlet.xml. If the file is not directly under the classesdirectory, then you cannot use the location as classpath:dispatcher-servlet.xml in your test
尝试将文件放在 src 文件夹下。然后将其复制到 WEB-INF/ classes文件夹。然后您可以将其称为 classpath:dispatcher-servlet.xml。如果该文件不直接位于classes目录下，则不能在测试中将该位置用作 classpath:dispatcher-servlet.xml

There seems to be some invalid class file on your classpath.
您的类路径上似乎有一些无效的类文件。
A blog(http://blog.163.com/mxl_880310/blog/static/1847222162012320102631220/) (in Traditional Chinese) describes a similar problem, the author solves it by checking if there is a zero size class file.
一个博客（http://blog.163.com/mxl_880310/blog/static/1847222162012320102631220/）（繁体中文）描述了类似的问题，作者通过检查是否有零大小的类文件来解决它。
