- 匯入座標
<dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.4</version> </dependency> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency>
- 配置上傳檔案解析器
<!--配置檔案上傳解析器--> <!--id只能是multipartResolver--> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!--上傳檔案的編碼型別--> <property name="defaultEncoding" value="UTF-8"/> <!--上傳檔案總大小--> <property name="maxUploadSize" value="524800"/> <!--上傳單個檔案的大小--> <property name="maxUploadSizePerFile" value="524800"/> </bean>
- 編寫Controller
@RequestMapping("/request9")
public void request9(MultipartFile[] multipartFile, HttpServletRequest httpServletRequest) throws IOException {
for (MultipartFile file : multipartFile) {
file.transferTo(new File("F:/ProjectTest/fileupload/"+file.getOriginalFilename()));
}
}
