网上搜的一些解决办法都是针对普通springMVC的，都是配置xml文件，如下：

<bean id="multipartResolver"  
          class="org.springframework.web.multipart.commons.CommonsMultipartResolver">  
        <!--1024*200即200k-->  
        <property name="maxUploadSize" value="204800"/>  
        <!--resolveLazily属性启用是为了推迟文件解析，以便在UploadAction 中捕获文件大小异常-->  
        <property name="resolveLazily" value="true"/>    
    </bean>

但是我用的是springBoot 所以上面的方法没用 又是各种搜索 最后搞定了 解决方法是在application.properties文件中加入如下两句

multipart.maxFileSize=50Mb(这里是限制的文件大小)
multipart.maxRequestSize=50Mb(这里是限制的文件大小)
