Restful与Spring MVC
Spring工作流程:
文件上传的处理:
解析参数的过滤器:
<filter> <filter-name>MultipartFilter</filter-name> <filter-class>org.springframework.web.multipart.support.MultipartFilter</filter-class> <init-param> <param-name>multipartResolverBeanName</param-name> <param-value>multipartResolver</param-value> </init-param> </filter> <filter-mapping> <filter-name>MultipartFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
转换http动作的:
<filter> <filter-name>hiddenHttpMethodFilter</filter-name> <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class> </filter> <filter-mapping> <filter-name>hiddenHttpMethodFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
错误页面信息:
解决方法:
代码:
<!-- 配置文件上传解析器 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 指定所上传文件的总大小不能超过20M。注意maxUploadSize属性的限制不是针对单个文件,而是所有文件的容量之和 --> <property name="maxUploadSize" value="20000000"/> <property name="defaultEncoding" value="utf-8"></property> </bean>
