我正在升级到Java 8，Spring 4和Spring Security 4（来自Java 7，Spring / Security 3，其中一切正常）。升级后，除了从服务器下载/流式传输到浏览器的能力之外的一切都可以正常工作。
对于UI，我们使用Vaadin。在一个实例中，我在浏览器中创建一个框架，该框架应显示PDF并在输入流中提供application / pdf类型的数据。在其他情况下，流返回浏览器以保存为文件
在Java中调试，我看到一个打开的InputStream，其中包含要在浏览器中下载的数据。数据从输入流中读取并写入response.OutputStream，它也是打开的。但是，当Tomcat尝试将输出流数据写入套接字时，它会抛出您可以在下面看到的异常（Tomcat 8.5在尝试刷新数据时抛出异常，Tomcat 7在尝试刷新数据时抛出异常 - 不同的实现）。似乎已终止与浏览器的连接。只有在使用Spring Security保护应用程序时才会发生这种情况。如果我删除安全性一切正常（它也适用于Spring Security 3）
非常感谢任何解决此问题的帮助！如果我能提供任何其他信息来解释这个问题，请告诉我。

在Spring 3到4迁移指南中找到答案
performSegueWithIdentifier:()`
第6.6节迁移标题
作为Spring Security 4.0+安全HTTP响应标头现在默认启用。
标题的存在（以某种方式）阻止了下载流。
建议：通过将csrf和headers标记添加到配置以使其运行来开始迁移，然后尝试了解是否可以禁用这些功能。另外，阅读指南，它可能会节省你一些时间......奇怪的是:-)
<security:http auto-config='true' use-expressions="true" realm="Illustration System">
<security:intercept-url pattern="/**" access="isFullyAuthenticated()" />
<security:http-basic />
<security:csrf disabled="true"/>

</security:http>
答案 1 :(得分：2)
Spring Boot中存在与Spring安全性相同的问题。我无法在HttpServletResponse outputStream中传输视频。用Java配置解决了它。
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
public class SecurityConfig extends WebSecurityConfigurerAdapter{
@Override
protected void configure(HttpSecurity http) throws Exception {
http
.csrf().disable()
.headers().disable()
.authorizeRequests()
.antMatchers("/").permitAll() // home page
.anyRequest().authenticated();
}
//... other methods
}
