java - ServletRequest.getServletContext() 的 UnsupportedOperationException

转载作者：行者123 更新时间：2023-12-02 01:41:47

我正在努力将现有应用程序从 Spring Boot 1.5 升级到 2.1。此应用程序作为 WAR 文件部署在现有 Tomcat 实例中。

我已经克服了大部分迁移障碍，但现在当 Thymeleaf 的 Spring Security Dialect 尝试检查 sec:authorize-url 时我看到了这一点规则，我得到一个 UnsupportedOperationException :

2019-08-13 15:31:22,836 [http-nio-8080-exec-7] ERROR org.springframework.boot.web.servlet.support.ErrorPageFilter  - Cannot forward to error page for request [/] as the response has already been committed. As a result, the response may have the wrong status code. If your application is running on WebSphere Application Server you may be able to resolve this problem by setting com.ibm.ws.webcontainer.invokeFlushAfterService to false

异常点处的Thymeleaf代码只是一个sec:authorize-url属性，例如:

<li sec:authorize-url="/foo">...</li>

我看不出 ServletContext 不可用的任何明显原因。任何有关如何进一步调试的指示将不胜感激。

这只发生在我登录之后，所以我知道 Thymeleaf 和 Servlet 的东西并没有从根本上被破坏，因为我看到了我的自定义登录页面。看来我错过了 Spring Security Dialect 的一些“陷阱”，或者可能是其他过滤器在某个地方出现了奇怪的情况？

更新

我在调试器中进行了研究，发现这种情况发生在 org.springframework.boot.actuate.autoconfigure.security.servlet.EndpointRequest.AbstractRequestMatcher#matches 时。使用 org.springframework.security.web.DummyRequest 调用.

最佳答案

好的，我发现我所做的更改破坏了这个。

作为迁移安全配置的一部分，我使用了 Actuator Security 中的 EndpointRequest 代码版本。 Spring Boot 2.0 迁移指南的部分，具体来说，我将其添加到现有的 antMatchers()

中

    http
        .authorizeRequests()
                // ...
                .requestMatchers(EndpointRequest.to("health"))
                    .permitAll()
                .requestMatchers(EndpointRequest.toAnyEndpoint())
                    .hasAnyRole("ADMIN", "MONITORING")
                // ...

这似乎与 Thymeleaf Spring Security Dialect 询问 Spring Security 的方式不太相符。

所以，我不确定这是否是 Spring Security、Thymeleaf 或两者中的错误，但至少我有一个解决方法......
