Spring MVC - HTTP 状态 405 - 不支持请求方法“POST”

Question

我已阅读与此问题相关的所有问题，但没有适合我的解决方案...

我有一个简单的上传表单。 控制器，我不是我用过很多次的控制器（虽然从不用于文件上传）。

@Controller
public class FileUploadController {
    @Autowired
    private HttpServletRequest request;

    @RequestMapping(value={"/upload"}, method=  RequestMethod.GET)
    public String getUploadForm() {

        return "/upload";

    }

    @RequestMapping(value={"/upload"}, method=RequestMethod.POST)
    public @ResponseBody String uploadedFile(@RequestParam("uploadedFile") UploadedFile uploadedFile, BindingResult result, ModelMap model,
                                RedirectAttributes redirectAttributes) {

        if (result.hasErrors()) {
            return "/upload";

        } 
            InputStream is = null;
            OutputStream os = null;
            MultipartFile file = uploadedFile.getFile();
            String fileName = file.getOriginalFilename();
            String imagepath = request.getSession().getServletContext().getRealPath("/resources/images");
            try {
                is = file.getInputStream();
                File newFile = new File(imagepath+"/"+fileName);

                if(!newFile.exists()){
                    newFile.createNewFile();
                }
                os = new FileOutputStream(newFile);
                int read=0;
                byte[] bytes = new byte[1024];
                while((read = is.read(bytes)) != -1){
                    os.write(bytes, 0, read);
                }
                redirectAttributes.addFlashAttribute("css", "success");
                redirectAttributes.addFlashAttribute("msg", "File "+fileName+ "aggiunto correttamente");
                model.addAttribute("fileName", fileName);


            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        return "redirect:/floors";

    }

}

然后我有上传表单，清理表单所有 css 部分：

<form:form method="POST" enctype="multipart/form-data" modelAttribute="uploadedFile">

         <input type="hidden"
             name="${_csrf.parameterName}"
             value="${_csrf.token}" />
        <form:errors path="*" cssClass="alert alert-danger alert-dismissible"
            element="div" />


            <label class="control-label col-sm-2">Carica
                immagine</label>

                <input type="file" name="file">
                <form:errors path="file" class="control-label" />


        <button id="singlebutton" name="singlebutton"
                        class="btn btn-primary" type="submit">Carica</button>

        </div>
    </form:form>

不知道有没有用，不过这是UploadedFile.java，很简单

导入 org.springframework.web.multipart.MultipartFile;

public class UploadedFile{

    MultipartFile file;


    public MultipartFile getFile() {
        return file;
    }

    public void setFile(MultipartFile file) {
        this.file = file;
    }

}

HTML 中的表单有：

<form id="uploadedFile" class="form-horizontal" action="/smartpark/upload" method="POST" enctype="multipart/form-data">

问题出在哪里？我什至无法理解 POST 请求在什么时候出错...

我正在添加调试：Spring 调试说：

浏览器网络日志什么也没说，只是POST资源没有完成

谢谢

Answer 1

IntelliJ 建议我使用 <form:form，它使用给了

<html xmlns:form="http://www.w3.org/1999/xhtml">

在我的 .html 文件的顶部。我在正文中更改为 <form，然后我的 POST 请求成功了。

Answer 2

我发现了问题。 在这个link之后，我看到使用spring和CSRF的分段文件上传必须小心处理。

所以我首先禁用了 CSRF 以查看是否一切顺利。在它之后，我添加了

@Override protected void beforeSpringSecurityFilterChain(ServletContext servletContext) { insertFilters(servletContext, new MultipartFilter()); }

到我的 SecurityWebApplicationInitializer.java 以便不需要身份验证在服务器上上传文件，而只需将它们移动到最终目的地。

比我必须配置 filterMultipartResolver 并且一切顺利。

谢谢大家

Answer 3

查看 spring 的 PathVariables。

@RequestMapping(value = " /upload/{pathName}", method=RequestMethod.POST)
public String getOrder(@PathVariable String pathName){
 // do what you need
}

Answer 4

需要考虑的事项：

检查您的请求标头，看看它是否提交到floors/upload。如果不尝试在表单标签中添加 action="floors/upload" 属性。

尝试将您的控制器更改为（不带path）

 @RequestMapping(value="upload", method=RequestMethod.POST)
