问题 I am creating a little Spring REST service. I have a findById() call: @GetMapping("/items/{id}") MyItem one(@PathVariable String id) { return repository.findById(id).orElseThrow(() -> new MyItemNotFoundException(id)); } If there is no MyItem object with the given id , I am throwing an exception using the Optional<T>.orElseThrow() method. This is very useful and quite simple. Now I added a findAll() call from the PagingAndSorting<T, ID> repository: @GetMapping("/items") List<MyItem> all() {

问题 I'm using <input type="file" multiple /> to upload a list of files. This works fine as is, but I want the ability to remove individual files before upload, so I'm storing the FileList in a separate object and routing it through xhr. However, it doesn't work. The form looks like this: <form:form commandName="documentsBean" enctype="multipart/form-data"> <input type="hidden" name="submittedFormAction" value="attachDocumentSave"/> <input type="file" name="files" id="attachFiles" multiple/>

问题 I want to append some data to the incoming request. Like random generated token or uuid to the incoming request. And then I want to process it through the controller. I came to know about ClientHttpRequestInterceptor . But looking at this doc, it seems like it only intercept the response, it doesn't intercept the request. Which is what I am not looking. Is there any other way to do this ? And how can I register this intercept in my RestController ? So that before controller process the

问题 I'm trying to secure my spring boot application using a XSSFilter like this: public class XSSFilter implements Filter { @Override public void init(FilterConfig filterConfig) throws ServletException { } @Override public void destroy() { } @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { chain.doFilter(new XSSRequestWrapper((HttpServletRequest) request), response); } } And the wrapper: public class

问题 Consider the following requirement: request parameters have to be bound to objects using Spring MVC 3.0. The request parameters contain underscores (e.g. http://myurl:80/x?param_one=1&param_two=2 ). These parameters should be bound to the following object: class MyObject { private Integer paramOne; private Integer paramTwo; ... } How would you go about doing this? Important note: consider that there may be a substantial amount of parameters and objects like this and that it's not considered

问题 Just want to see whether I'm interpreting the answer to this question the right way. If we only need to secure one path like this: http.antMatcher("/api/**").authorizeRequests()....

If we need to secure multiple URL paths like this: http .authorizeRequests() .antMatchers("/high_level_url_A/sub_level_1").hasRole('USER') .antMatchers("/high_level_url_A/sub_level_2").hasRole('USER2') ... Then use antMatchers() . There are two answers in this question, but the example

问题 How can I validate that the body request part is not empty? @PostMapping("/messages") @ResponseStatus(HttpStatus.CREATED) fun createMessage(@Valid @RequestPart message: MessageCreate, @Valid @RequestPart @NotEmpty body: MultipartFile, @RequestParam attachments: List<MultipartFile>) { return service.create(message, body, attachments) } I tried to create a custom validator annotation that checks body.isEmpty() result but it has no effect. What is missing ? Is it possible do to it this way ? 回答1

问题 I've implemented a Spring MVC REST service that accepts a multipart message with both a file upload and a JSON body as the constitutive parts. Here are the main classes involved: My Controller: @RestController public class MyController { @Autowired private MyService myService; @RequestMapping(value = "/publish", method = RequestMethod.POST, consumes = "multipart/form-data", produces = "application/json") public PublishContentResponse publishContent(@RequestPart("json") PublishContentRequest
