Tin*_*iny 8 spring struts2 csrf spring-security csrf-protection
我用,
其中,我使用内置安全令牌来防范CSRF攻击.
Struts表单如下所示.
<s:form namespace="/admin_side"
action="Category"
enctype="multipart/form-data"
method="POST"
validate="true"
id="dataForm"
name="dataForm">
<s:hidden name="%{#attr._csrf.parameterName}"
value="%{#attr._csrf.token}"/>
</s:form>
生成的HTML代码如下.
<form id="dataForm"
name="dataForm"
action="/TestStruts/admin_side/Category.action"
method="POST"
enctype="multipart/form-data">
<input type="hidden"
name="_csrf"
value="3748c228-85c6-4c3f-accf-b17d1efba1c5"
id="dataForm__csrf">
</form>
这工作正常,除非请求是多部分,在这种情况下,请求以状态代码403结束.
HTTP状态403 - 在请求参数'_csrf'或标题'X-CSRF-TOKEN'上找到无效的CSRF令牌'null'.
类型状态报告
消息无效的CSRF令牌'null'在请求参数'_csrf'或标题'X-CSRF-TOKEN'上找到.
description禁止访问指定的资源.
该spring-security.xml文件如下.

那么,当请求是多部分时,在哪里查找此令牌？(这根本不应该和Struts有关.)
如果需要,UserDetailsService可以在我之前的这个问题中找到实现.
MultipartFilter在Spring Security之前放置也没有帮助.
该web.xml文件如下所示.

它只有在令牌作为查询字符串参数附加如下时才有效,但是不建议这样做.
<s:form namespace="/admin_side"
action="Category?%{#attr._csrf.parameterName}=%{#attr._csrf.token}"
enctype="multipart/form-data"
method="POST"
validate="true"
id="dataForm"
name="dataForm">
...
<s:form>
如果您使用@annotations，并且jsp 视图是这样的：
<form:form id="profileForm" action="profile?id=${param.id}" method="POST"
modelAttribute="appUser" enctype="multipart/form-data" >
...
<input type="file" name="file">
...
<input type="hidden" name="${_csrf.parameterName}"
value="${_csrf.token}" />
</form:form>
这可能有帮助：
AppConfig.java :
@EnableWebMvc
@Configuration
@Import({ SecurityConfig.class })
public class AppConfig {
@Bean(name = "filterMultipartResolver")
public CommonsMultipartResolver filterMultipartResolver() {
CommonsMultipartResolver filterMultipartResolver = new CommonsMultipartResolver();
filterMultipartResolver.setDefaultEncoding("utf-8");
// resolver.setMaxUploadSize(512000);
return filterMultipartResolver;
}
...
SecurityConfig.java 扩展了 WebSecurityConfigurerAdapter 并且是 SpringSecurity 的配置
multipart/form-data过滤器（MultipartFilter）需要在启用CSRF的SecurityConfig之前注册。你可以这样做：
SecurityInitializer.java：
public class SecurityInitializer extends
AbstractSecurityWebApplicationInitializer {
@Override
protected void beforeSpringSecurityFilterChain(ServletContext servletContext) {
super.beforeSpringSecurityFilterChain(servletContext);
// CSRF for multipart form data filter:
FilterRegistration.Dynamic springMultipartFilter;
springMultipartFilter = servletContext.addFilter(
"springMultipartFilter", new MultipartFilter());
springMultipartFilter.addMappingForUrlPatterns(null, false, "/*");
}
}
在这种情况下，由于它是一个多部分请求，其中 CSRF 令牌对 Spring 安全性不可用，除非MultipartFilter正确MultipartResolver配置，以便 Spring 可以处理多部分请求。
MulipartResolver文件中applicationContext.xml必须按如下方式注册
<bean id="filterMultipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize" value="-1" />
</bean>
-1的属性值maxUploadSize对上传文件的大小没有限制。该值可能会根据要求而变化。如果是多个文件，则文件大小为所有上传文件的大小。
还，
<servlet-name>/*</servlet-name>
的<filter-mapping>需要MultipartFilter更改为
<url-pattern>/*</url-pattern>
如果只有 Spring MVC，这会工作得很好。
但如果它是 Spring 和 Struts(2) 的集成，则会在关联的 Struts 操作类中引发另一个问题。上传文件的信息将位于null关联的 Struts 操作类中。
