我的测试类是

@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服务器3.0
its located at web/WEB-INF/dispatcher-servlet.xml.

推荐答案
很可能你的一个spring bean里面有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
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
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spring 3.。
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.
避免这种失败：
