上载文件时不支持错误405请求方法’POST’
这是我的applicationContext.xml:

</beans>
我的控制器:
@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>
我认为问题出在我的控制器上,也许是因为我将Spring 4注释与Spring3 conf混在一起了?
谢谢你的帮助!!

问题答案:
好了,我终于找到了问题所在。
首先,我使用了几乎所有教程中都提到的MultipartFile,并使用@ModelAttribute将此MultipartFile映射到表单。但这不是真正的问题:我只是清理了实现以使其更标准。
然后,我在DEBUG日志中发现了问题:
20:58:38,370 DEBUG CsrfFilter:95 - Invalid CSRF token found for http://localhost:8080/meltdown/bo/createnews
并且我使用spring推荐来纠正它:(请参阅spring security csrf doc)
将CSRF保护与multipart / form-data一起使用有两种选择。每个选项都有其权衡。
在Spring Security之前放置MultipartFilter
包含CSRF令牌
我使用了第二个选项,并将 ?$ { csrf.parameterName} = $ { csrf.token} 放在表单操作网址的末尾。
它可以工作,但我必须对所有这些东西进行深入了解,并检查真正的内容以及是否需要csrf。
谢谢你们每一个人的帮助
