关于报错问题的解决

在spring mvc中引用<mvc:default-servlet-handler/>后启动程序异常如下：

ERROR: org.springframework.web.servlet.DispatcherServlet - Context initialization failed
org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'org.springframework.validation.beanvalidation.LocalValidatorFactoryBean#0': Invocation of init method failed; nested exception is javax.validation.ValidationException: Unable to find a default provider

找问题很久，发现原来是JAR包冲突，去掉如下包：bean-validator.jar或者javax-validator。

问题解决。
