Question

搭建springmvc框架在<mvc:annotation-driven/>时 不能创建ApplicationContext 容器 ，去掉这句可以创建

为什么我在Spring的配置文件中使用<mvc:annotation-driven />注解以后,测试类就报错,每次都要手动屏蔽掉这句注解,才能测试,请高手指导下,这是测试类:

报错如下:

Exception in thread "main" 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 instantiate Configuration.

jar包有这几个:

Answer 1

这是头部的xmlns造成的，里面需要追加：xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="...http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd.."

其中的3.2是版本好，根据你现行的版本更改

Answer 2

spring jar的问题,换成3.2以上的jar包

Answer 3

测试类用的是spring test么?
