在Spring中使用<mvc:annotation-driven />注解,测试类报错问题

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.

Answer 1

javax.validation.ValidationException: Unable to instantiate Configuration.
配置文件的问题，检查下spring的配置文件applicationContext.xml

Answer 2

<mvc:annotation-driven /> 表示注入 spring mvc 一系列组件到容器中的意思，此时容器要使用applicationContext的子容器webApplicationContext才行。
所以，建议你修改代码 ApplicationContext ac = new ClassPa..... 这一段代码如下：
ApplicationContext ac = new FileSystemXmlApplicationContext("...."); //省略号替换为配置路径
ac.getBean("beanId");
