Question

我正在尝试使用Spring MVC 4上传带有Web应用程序的文件但是我收到错误：

在请求参数'_csrf'或标题'X-CSRF-TOKEN'上找到无效的CSRF令牌'null'。

春季版：

Spring Version 4.1.7.RELEASE

Spring Security 4.0.1.RELEASE

代码：

的web.xml

我通过遵循the accepted answer到Spring Security 3.2, CSRF and multipart requests的第二点中的一般建议来修复此问题，但使用的是Spring Security 4.0.1.RELEASE而不是版本3.2。

更改1

将Web应用程序从Servlet API 2.4更新为Servlet API 3.0：

<?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>

更改2

使用基于Java的配置，创建了StandardServletMultipartResolver，它使用Servlet 3.0的多部分处理，不需要commons-fileupload。请注意，原始实现忽略了显式创建任何多部分解析程序，尽管它在Maven项目中确实包含了依赖项commons-fileupload。

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

更改3

为DispatcherServlet添加了“multipart-config”：

在web.xml：

<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。
