spring 的配置文件

<!-- SpringMVC上傳文件時，需要配置MultipartResolver處理器 -->
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="UTF-8"/>
<!-- 指定所上傳文件的總大小不能超過200KB。注意maxUploadSize屬性的限制不是針對單個文件，而是所有文件的容量之和 -->
<property name="maxUploadSize" value="200000000"/>
</bean>

<!-- SpringMVC在超出上傳文件限制時，會拋出org.springframework.web.multipart.MaxUploadSizeExceededException
該異常是SpringMVC在檢查上傳的文件信息時拋出來的，而且此時還沒有進入到Controller方法中 -->
<bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
<property name="exceptionMappings">
<props>
<!-- 遇到MaxUploadSizeExceededException異常時，自動跳轉到404頁面 -->
<prop key="org.springframework.web.multipart.MaxUploadSizeExceededException">/error/404</prop>
</props>
</property>
</bean>
