SpringMvc代码

jar包

commons-fileupload

commons-io

spring-mvc.xml配置

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="UTF-8" />
</bean>

Controller

@RequestMapping(value = "api/v1/upload", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public Map upload (@RequestParam(value = "files") MultipartFile [] files,
@RequestParam(value = "id") String id,
HttpServletRequest request, HttpServletResponse response) {
Map res = new HashMap();
try {
log.info("upload>>>>>id:{}", id);
if (files!=null) {
for (MultipartFile file:files) {
log.info("filename:{}", file.getOriginalFilename());
}
}
} catch (Exception e) {
log.error("upload>>>>异常:{}", e.toString());
}
log.info("upload>>>>返回结果:{}", res);
return res;
}

保存到本地

// copy File
public boolean copyFile (MultipartFile tempFile, String filePath) {
Boolean res = false;

try {
File file = new File(filePath);
if (!file.getParentFile().exists()) {
file.getParentFile().mkdirs();
}
// 将文件拷贝到当前目录下
tempFile.transferTo(file);
res = true;
} catch (Exception e) {
log.info("copyFile>>>>异常:{}", e.toString());
}
return res;
}

app.controller('uploadCtrl', ["$scope", "$http", function($scope, $http) {
$scope.submit = function () {
var fd = new FormData();
var files = document.querySelector('input[name="files"]').files;
for (var i=0; i<files.length; i++) {
fd.append("files", files[i]);
