我成功运行了以下示例（简单的 Spring Web 应用程序）： https ://www.youtube.com/watch?v=GTrNkhVnJBU

现在我想在一个基于 Spring Boot 和 Vaadin TouchKit 的项目中使用 Spring Loaded。

当我进行更改时（例如 ComboBox 的新标题），Spring Loaded 似乎可以识别它：

2015-09-03 10:23:08.823  INFO 1956 --- [Loader@799dbc3b] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/error]}" onto public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)

但是按 F5 刷新浏览器后，我看不到变化（组合框的标题与以前保持一致）。

我错过了什么吗？在 Spring Loaded 与 Vaadin TouchKit 一起工作之前，我还需要做其他事情吗？

感谢您的阅读以及您可能提前获得的任何提示！

编辑：

当我在简单的 Spring Web 应用程序示例中进行更改时，我得到以下日志输出：

2015-09-03 10:51:06.503  INFO 8388 --- [Loader@14dad5dc] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/]}" onto java.lang.String ???.???.tests.springloaded.SpringLoadedController.home()
2015-09-03 10:51:06.504  INFO 8388 --- [Loader@14dad5dc] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/error]}" onto public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)

所以上下文“/”似乎在那里更新，但不是在 TouchKit 应用程序中。

我在https://github.com/Artur-/spring-boot-loaded-vaadin使用 Spring Boot + Spring Loaded + Vaadin 创建了一个简单的示例项目

使用 mvn install spring-boot:run 运行它，您可以更改 UI 类并在刷新后查看更改。

我看不出 TouchKit 会改变什么，除非你的 UI 类上有 @PreserveOnRefresh。在这种情况下，除了刷新之外，您还需要通过将 ?restartApplication 添加到 URL 来强制创建新的 UI 实例。
