org.springframework.validation.beanvalidation.OptionalValidatorFactoryBean#0

环境：SSM+Tomcat7+Maven
在使用org.hibernate.validator的标签限制对象的字符值的时候，出现当下错误
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘org.springframework.validation.beanvalidation.OptionalValidatorFactoryBean#0’: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: javax/el/ELManager

org.hibernate.validator版本：

  
    org.hibernate.validator
    hibernate-validator
    6.0.9.Final
  
  
    javax.validation
    validation-api
    2.0.1.Final
  

尝试pom.xml添加了依赖后仍然无法解决问题：

 
    javax.el
    javax.el-api
    3.0.0
  

后来查看了Tomcat的版本支持信息，原使用tomcat7版本和el3.0的版本，查看了tomcat对其他规范确实 是自己没有留意到版本的问题，一味的追求高版本，谨记以后多看看文档。
