<!-- SpringMVC上传文件时，需要配置MultipartResolver处理器 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="defaultEncoding" value="UTF-8"/> <!-- 指定所上传文件的总大小不能超过200KB。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="1024000"/> <property name="fileItemFactory.sizeThreshold" value="0"></property> </bean>
查看该类源码
有一段说明文档
* <p>Provides "maxUploadSize", "maxInMemorySize" and "defaultEncoding" settings as
* bean properties (inherited from {@link CommonsFileUploadSupport}). See corresponding
* ServletFileUpload / DiskFileItemFactory properties ("sizeMax", "sizeThreshold",
* "headerEncoding") for details in terms of defaults and accepted values.
进入 CommonsFileUploadSupport
public abstract class CommonsFileUploadSupport {
protected final Log logger = LogFactory.getLog(getClass());
private final DiskFileItemFactory fileItemFactory;
private final FileUpload fileUpload;
private boolean uploadTempDirSpecified = false;
进入
DiskFileItemFactory 类
看到
/** * The threshold above which uploads will be stored on disk. */ private int sizeThreshold = DEFAULT_SIZE_THRESHOLD;//DEFAULT_SIZE_THRESHOLD=10240就是10k
设置下这个参数即可。
spring mvc MultipartFile 上传文件 当文件较小时(10k) ，无法上传成功 。
