我想我已经在网上看到了关于这个话题的每一篇文章,但我无法纠正这个错误:
我有一个使用Security和Spring的Web,我想创建一个表单来上传一个图像(您必须被记录下来才能这样做),但是无论我用我在论坛上找到的东西扭曲代码的方式,我有一个错误405请求方法'POST‘在上传文件时不支持
这是我的applicationContext.xml:

@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>我认为这个问题来自于我的控制器,也许是因为我把Spring4注释与Spring3 conf混淆了?
谢谢你的帮助!!

好的,我终于找到问题了。
首先,我在几乎所有教程中都提到了MultipartFile,我使用@ModelAttribute将这个MultipartFile映射到我的表单中。但这并不是真正的问题:我只是清理了植入,以使它更标准。
然后,我在调试日志中发现了一些错误:
20:58:38,370 DEBUG CsrfFilter:95 - Invalid CSRF token found for http://localhost:8080/meltdown/bo/createnews我使用了spring建议来纠正它:(请参阅spring安全csrf文档)
使用多部分/表单数据的CSRF保护有两种选择。每一种选择都有它的权衡。 在春季安全前放置MultipartFilter 包括CSRF令牌的动作
我使用了第二个选项,并将?${_csrf.parameterName}=${_csrf.token}放在表单操作url的末尾。
它很管用,但我得挖一些东西下面的东西.看看什么才是真正的我是否需要csrf。
谢谢大家的帮助
