Grails 3 + Tomcat 8：无法解析名称为“grailsDispatcherServlet”的 servlet 中名称为“/login/authAjax”的视图

Posted 2023-02-27

【中文标题】Grails 3 + Tomcat 8：无法解析名称为“grailsDispatcherServlet”的 servlet 中名称为“/login/authAjax”的视图

【英文标题】：Grails 3 + Tomcat 8: Could not resolve view with name '/login/authAjax' in servlet with name 'grailsDispatcherServlet'

【问题描述】：

我将 Grails 3.1.3 与 Spring Security 3.0.3 一起使用（编译“org.grails.plugins:spring-security-core:3.0.3”）。我的问题仅在应用程序部署到 Tomcat 8 实例时发生。使用run-app 完全没问题，但不幸的是，我们首选的部署方法是 Tomcat。

这是控制器代码（由插件生成）。

def authAjax() 
    log.info "authAjax: $params"
    response.setHeader 'Location', SpringSecurityUtils.securityConfig.auth.ajaxLoginFormUrl
    response.sendError HttpServletResponse.SC_UNAUTHORIZED

这是一个不错的 Grails 堆栈跟踪。

有人知道为什么会发生这种情况吗？

【问题讨论】：

对我来说似乎是一个 Grails 错误，因为它一直在运行并且适用于 run-app。尝试在方法末尾添加response.flushBuffer() 以查看是否让 Grails 意识到响应已提交并且不查找视图

【参考方案1】：

正如我在评论中提到的，这是一个 Grails 或 Spring Boot 错误，因为它在 2.5.x 中工作并在 run-app 中工作。添加对response.flushBuffer() 的调用可以解决该问题：

def authAjax() 
   log.info "authAjax: $params"
   response.setHeader 'Location', SpringSecurityUtils.securityConfig.auth.ajaxLoginFormUrl
   response.sendError HttpServletResponse.SC_UNAUTHORIZED
   response.flushBuffer()

我将此报告为 grails-core 问题，因为它与插件无关： https://github.com/grails/grails-core/issues/9900

【讨论】：

这是您定制的旧控制器吗？在 2.0 插件中，它使用您拥有的代码，但在 3.0.0.M2 左右，有一个请求请求将 sendError() 调用更改为 render(status: HttpServletResponse.SC_UNAUTHORIZED, text: 'Unauthorized')。因为它调用了一个 Grails 控制器方法，所以它确实提交了响应并阻止了视图渲染/查找

是的。我们已将应用程序从 1.3 升级到 3.1。

很酷，因此将sendError() 和flushBuffer() 调用替换为仅render() 调用会更简洁一些，并且与当前实现保持一致。

【参考方案2】：

您可能需要更多地搜索此配置参数：

grails.plugin.springsecurity.auth.ajaxLoginFormUrl

我认为默认值为/login/authAjax，但您可以将其更改为您的自定义网址。
