Spring MVC Error 405请求方法' POST'上传文件时不支持

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:(

我有一个使用Spring Security和Spring Mvc的Web应用程序,我想创建一个表单来上传图像(你必须要记录才能这样做),但不管用我在论坛上找到的代码扭曲我的代码,我上传文件时不支持错误405请求方法'POST'

这是我的applicationContext.xml:

 <beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:context="http://www.springframework.org/schema/context"
   xsi:schemaLocation="http://www.springframework.org/schema/beans 
                       http://www.springframework.org/schema/beans/spring-beans.xsd
                       http://www.springframework.org/schema/context
                       http://www.springframework.org/schema/context/spring-context.xsd">


<context:component-scan base-package="com.meltdown.*" />
<context:annotation-config />

<bean id="userDAO" class="com.meltdown.bo.users.infra.impl.JdbcUserDAO">
    <property name="dataSource" ref="dataSource" />
 </bean>
<bean id="userService" class="com.meltdown.bo.users.application.service.impl.StandardUserService" />

 <bean id="barDAO" class="com.meltdown.bo.bars.infra.impl.JdbcBarDAO">
    <property name="dataSource" ref="dataSource" />
 </bean>
<bean id="barService" class="com.meltdown.bo.bars.application.service.impl.StandardBarService" />

 <bean id="newsDAO" class="com.meltdown.bo.news.infra.impl.JdbcNewsDAO">
    <property name="dataSource" ref="dataSource" />
 </bean>
<bean id="newsService" class="com.meltdown.bo.news.application.service.impl.StandardNewsService" />

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- one of the properties available; the maximum file size in bytes -->
<property name="maxUploadSize" value="100000"/>
</bean>
</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?

感谢您的帮助!!

答案 0 :(得分:4)

好的,我终于找到了问题。

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。

然后,我在DEBUG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spring建议来纠正它:(参见spring security csrf doc)

  

对multipart / form-data使用CSRF保护有两种选择。每个选项都有其权衡。

     

在Spring Security之前放置MultipartFilter

     

在行动中加入CSRF令牌

我使用了第二个选项,并在表单的操作网址末尾放置了?$ {_ csrf.parameterName} = $ {_ csrf.token}

它可以工作,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。

谢谢大家的帮助
