尝试上传时无效的 CSRF 令牌 Spring 4 MVC

Question

我正在尝试使用 Spring MVC 4 通过 Web 应用程序上传文件，但出现错误：

Invalid CSRF Token 'null' was found on the request parameter '_csrf' or header 'X-CSRF-TOKEN'.

Spring版本：

Spring Version 4.1.7.RELEASE

Spring Security 4.0.1.RELEASE

代码：

我按照 the accepted answer to Spring Security 3.2, CSRF and multipart requests 第二点中的一般建议解决了这个问题，但使用 Spring Security 4.0.1.RELEASE 而不是版本 3.2.

改变 1

从 Servlet API 2.4 to Servlet API 3.0 更新了 Web 应用程序：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
          http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
          version="3.0">
....
</web-app>

使用基于 Java 的配置，创建了 StandardServletMultipartResolver which uses the multipart handling of Servlet 3.0 and does not require commons-fileupload。请注意，原始实现忽略了显式创建任何多部分解析器，尽管它确实在 Maven 项目中包含依赖项 commons-fileupload。

@Configuration
public class WebApplicationConfiguration {
    @Bean
    public MultipartResolver multipartResolver() {
        return new StandardServletMultipartResolver();
    }
}

变3

已将 "multipart-config" 添加到 DispatcherServlet:

在web.xml中：

<servlet>
    <servlet-name>spring-web</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
    <multipart-config>
        <location>/tmp</location>
        <max-file-size>1000000</max-file-size>
        <max-request-size>1000000</max-request-size>
        <file-size-threshold>10000</file-size-threshold>
    </multipart-config>
</servlet>

使用Java:

public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {
    public SecurityWebApplicationInitializer() {
    super(SecurityConfiguration.class);
    }

    @Override
    protected void beforeSpringSecurityFilterChain(ServletContext servletContext) {
    final XmlWebApplicationContext appContext = new XmlWebApplicationContext();
    appContext.setConfigLocation("/WEB-INF/spring-web-servlet.xml");

    final ServletRegistration.Dynamic registration = servletContext.addServlet("dispatcher",
        new DispatcherServlet(appContext));
    registration.setLoadOnStartup(1);
    registration.addMapping("/");
    registration.setMultipartConfig(new MultipartConfigElement("", 1000000, 1000000, 100000));
    }
}

从 Maven 项目中删除了依赖项 commons-fileupload。
