1、The resource is not on the build path of a Java project
然后把相应的依赖加入构建路径
2、Type mismatch: cannot convert from Class<SpringJUnit4ClassRunner> to Class<? extends Runner>
版本过低，spring不支持junit4.5以下的。
3、No grammar constraints (DTD or XML schema) detected for the document
警告，没关系
4、java.lang.IllegalStateException: Failed to load ApplicationContext
ested exception is org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'beans'
http://www.springframework.org/schema/context/spring-context-3.0.xsd
schema写成了scheme
5、java.lang.ClassNotFoundException: org.aopalliance.intercept.MethodInterceptor
因为缺少aopaliance.jar包
6、java.lang.ClassNotFoundException: org.aspectj.weaver.BCException
aspectjweaver.jar
7、org.springframework.aop.framework.AopConfigException: Cannot proxy target class because CGLIB2 is not available. Add CGLIB to the class path or specify proxy interfaces.
缺少jar包 cglib-2.1.3.jar 导入cglib-nodep-2.1_3.jar包，或者导入asm-2.2.3.jar和cglib-2.2.jar
缺少的包下载：下载
(junit-4.5.jar，cglib-nodep-2.1_3.jar,aopalliance.jar,aspectjweaver.jar)
