尝试上传时无效的CSRF令牌Spring 4 MVC
问题内容：
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：
在请求参数’_csrf’或标头’X-CSRF-TOKEN’上发现无效的CSRF令牌’null’。
spring版：
spring版本4.1.7.RELEASE
Spring Security 4.0.1。发布

问题答案：
我通过遵循对 _Spring Security3.2，CSRF和multipart请求_的公认答案的第二点中的一般建议来解决此问题，但使用的是SpringSecurity 4.0.1.RELEASE而不是3.2版。
变更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>
变更2
使用基于Java的配置，创建了一个StandardServletMultipartResolver，它使用Servlet
3.0的多部分处理，并且不需要commons-fileupload。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commons- fileupload在Maven项目中包括了依赖项。
@Configuration
public class WebApplicationConfiguration {
@Bean
public MultipartResolver multipartResolver() {
return new StandardServletMultipartResolver();
}
}
变更3
在“”中添加了“ multipart-config”
DispatcherServlet：
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));
}
}
变更4
commons-fileupload从Maven项目中删除了依赖性。
