Question

当我运行junit测试类时，出现以下异常？我怎么解决这个问题？

我的测试类是

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

public class CandidateDAOImplTest{
@Autowired
    public CandidateDAO candidateService;


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

调度-servlet.xml中

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

Answer 1

很可能你的一个spring bean中有lambda表达式。显然，如果代码中有某个lambda，则spring 3 beans无法初始化。如果不能选择迁移到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。我有同样的问题，它帮助了我，我仍然可以使用带有jre / jdk 8的弹簧3。

避免这种失败：

 Caused by: java.lang.ArrayIndexOutOfBoundsException: 10348
    at org.springframework.asm.ClassReader.<init>(Unknown Source)

Answer 2

您尚未说明您使用的是哪种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+）。

查看此问题的答案： Java 1.8 ASM ClassReader failed to parse class file - probably due to a new Java class file version that isn't supported yet

Answer 3

问题是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。

Answer 4

尝试将文件放在src文件夹下。然后将其复制到WEB-INF / 类文件夹。然后您可以将其称为classpath：dispatcher-servlet.xml。如果文件不在类目录下，则不能在测试中将该位置用作classpath：dispatcher-servlet.xml

Answer 5

您的类路径中似乎存在一些无效的类文件。

博客（http://blog.163.com/mxl_880310/blog/static/1847222162012320102631220/）（繁体中文）描述了一个类似的问题，作者通过检查是否存在零大小的类文件来解决它。

无法在ClassReader中加载由ArrayIndexOutOfBoundsException引起的ApplicationContext
