当我运行 junit 测试类时，会出现以下异常吗？我该如何解决这个问题？

我的测试课是

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:dispatcher-servlet.xml")

public class CandidateDAOImplTest{
@Autowired
    public CandidateDAO candidateService;


    @Test
    public void testGetCandidate() {...}
}

它位于 web/WEB-INF/dispatcher-servlet.xml。
我正在使用 netbeams ied 7.3 和 glassfish server 3.0

很可能您的一个 spring bean 中有 lambda 表达式。显然，如果代码中某处存在 lambda，则 spring 3 bean 无法初始化。如果无法迁移到 spring 4，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) { ... }
}

或将 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。

避免这种失败：

您还没有说明您使用的是哪个 JDK。如果您使用的是 1.8，那么您可能会发现您需要将 Spring 升级到 4（或 yurez 指出的 3.2.9+）。

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

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。

尝试将文件放在 src 文件夹下。然后它将被复制到 WEB-INF/ classes文件夹。然后您可以将其称为 classpath:dispatcher-servlet.xml。如果文件不是直接在类目录下，那么您不能在测试中将该位置用作 classpath:dispatcher-servlet.xml

您的类路径上似乎有一些无效的类文件。

一篇博客（http://blog.163.com/mxl_880310/blog/static/1847222162012320102631220/）（繁体中文）描述了类似的问题，作者通过检查是否存在零大小的类文件来解决。
