8.jar包如下：

cglib-nodep-2.1_3.jar
commons-logging-1.1.1.jar
commons-logging.jar
jakarta-oro-2.0.8.jar
jstl.jar
log4j-1.2.9.jar
spring-beans-4.0.0.RELEASE.jar
spring-context-4.0.0.RELEASE.jar
spring-core-4.0.0.RELEASE.jar
spring-expression-4.0.0.RELEASE.jar
spring.jar
standard.jar

经过多方查找，stackOverFlow csdn等论坛，猜测是jar包添加冲突问题，逐个删除jar包，发现无效。最后全部删除。换上

commons-logging.jar
jstl.jar
log4j-1.2.9.jar
spring.jar
standard.jar

问题解决
