Spring MVC Error 405上传文件时不支持请求方法'POST' [英] Spring MVC Error 405 Request method 'POST' not supported when uploading a file
问题描述
我想我已经在网上看过关于这个话题的每一篇文章，但我无法纠正这个错误：（
I think I have seen every post on the web about this topic but I cannot correct that bug :(
我有一个使用Spring Security和Spring Mvc的Web应用程序并且我想创建一个表单来上传图像（你必须记录才能这样做）但是无论我用论坛上的内容扭曲我的代码，我都有一个错误405请求方法'POST'没有上传文件时支持
I have a Web App using Spring Security and Spring Mvc and I want to create a form to upload an image (you have to be logged to do that) but whatever the way I twist my code with what I find on forums, I have an Error 405 Request method 'POST' not supported when uploading a file
这是我的applicationContext.xml：
Here is my applicationContext.xml :

<!-- one of the properties available; the maximum file size in bytes -->
<property name="maxUploadSize" value="100000"/>
</bean>
</beans>
我的经理人：
@Controller
public class FileUploadController {
@RequestMapping(value="/bo/uploadImage", method = RequestMethod.GET)
public String uploadImage() {
return "bo_uploadimage";
}
@RequestMapping(value="/bo/uploadImage", method = RequestMethod.POST)
public String uploadImage(@RequestParam(value = "file")FileUploadBean file, BindException errors, Map<String, Object> model) {
System.out.println("#############################" + file);
return "bo_uploadimage";
}
}
public class FileUploadBean{
private byte[] file;
public void setFile(byte[] file) {
this.file = file;
}
public byte[] getFile() {
return file;
}
}
jsp：
<html>
<head>
<title>Upload a file please</title>
</head>
<body>
<h1>Please upload a file</h1>
<form method="post" action="/meltdown/bo/uploadImage" enctype="multipart/form-data">
<input type="file" name="file"/>
<input type="submit"/>
</form>
</body>
</html>
我认为问题来自我的控制器，也许是因为我将Spring 4注释与Spring3 conf混合在一起？
I think the problem come from my controler and maybe because I mixed up Spring 4 annotations with Spring3 conf?
感谢您的帮助!!

推荐答案
好的，我终于发现了问题。
Ok so I finally find out the problem.
首先，我使用了几乎所有教程中提到的MultipartFile，并使用@ModelAttribute将此MultipartFile映射到我的表单。但问题并非如此：我只是清理了这个问题，使其更加标准化。
First, I used MultipartFile as mentionned in almost all tutorials and i used an @ModelAttribute to map this MultipartFile to my form. But it was not really the problem : I just cleaned up the implmentation to make it more standard.
然后，我在DEBUG日志中发现了一些错误：
Then, I discovered something wrong in the DEBUG logs :
20:58:38,370 DEBUG CsrfFilter:95 - Invalid CSRF token found for http://localhost:8080/meltdown/bo/createnews
我使用spring建议来纠正它:(参见spring security csrf doc）
and i used spring recommendation to correct it : (see spring security csrf doc)
使用CSRF保护和multipart / form-data有两种选择。每个选项都有权衡。
There are two options to using CSRF protection with multipart/form-data. Each option has its tradeoffs.
在Spring Security之前放置MultipartFilter
Placing MultipartFilter before Spring Security
在行动中包含CSRF令牌
Include CSRF token in action
我使用了第二个选项并在结尾处放置了？$ {_ csrf.parameterName} = $ {_ csrf.token} 我的表格的动作网址。
I used second option and placed ?${_csrf.parameterName}=${_csrf.token} at the end of my form's action url.
它有效，但我必须在所有这些东西下挖掘一下...并检查什么是真的，如果我需要csrf。
It works but I have to dig a bit what s under all that stuff... And to check what is really and if I need csrf.
