java - 包含文件和 JSON 对象的多部分请求

Question

我尝试创建将获取多部分文件和 json 作为输入参数的函数。我写了这样的函数，如下:

@RequestMapping(method = RequestMethod.PUT)
    public ResponseEntity<UserWithPhoto> update(@RequestHeader(value="Access-key") String accessKey,
                                         @RequestHeader(value="Secret-key") String secretKey,
                                         @RequestPart("user") String string,
                                         @RequestPart("photo") MultipartFile file) throws Exception{
            User user = new ObjectMapper().readValue(string, User.class);

但问题是无法测试。我像这样使用 Postman 客户端并收到错误 org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.web.multipart.MultipartException: Could not parse multipart servlet request; nested exception is java.lang.IllegalStateException: Unable to process parts as no multi-part configuration has been provided
我相信它是因为我没有设置 postman 写

您是否尝试过将 MultipartResolver 添加到 Spring MVC 配置中:

<bean id="multipartResolver"
    class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
