前言
这里用ajax文件上传，并携带几个参数，网上查到的大多都是没带参数只有文件的。 由于我项目代码太多，这里只给出关键代码。
操作
我用的SSM框架，传之前，先在WEB-INF/dispatcherServlet-servlet.xml中配置multipartResolver
<!-- 文件上传 -->
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- 设置上传文件的最大尺寸为1MB -->
<property name="maxUploadSize" value="1048576" />
<!-- 字符编码 -->
<property name="defaultEncoding" value="UTF-8" />
</bean>前端代码
