java - 浏览器不显示 Vaadin 项目的更改 - 使用 Windows

Question

我的网络浏览器都没有显示我的 vaadin 项目的当前更改。

• vaadin项目部署在tomcat上
• 我在 eclipse 中使用 tomact 6 和 vaadin 6
• 我尝试重启 tomcat - 没有成功
• 我还尝试删除浏览器的缓存 - 没有成功
• 我还在 server.xml 中设置了项目上下文的 cookies="false"- 没有成功

这是我的 eclipse 控制台:

感谢帮助

更新 1:我发现我必须重新启动 Eclipse 才能正常工作，但这真的很烦人

解决方案:问题出在我的操作系统上。 Windows 会锁定文件。所以你需要告诉 tomcat 他必须解锁它们。读这个:

在我的 tomcat 的 context.xml 中完成这些更改后，我只需要重新启动 tomcat，一切都像往常一样工作。

Answer 1

Java Servlet 不像 PHP、python 等。您必须等待部署。在 eclipse crtl+shift+s 中更改某些内容然后等待并查看控制台。 20 秒到 5 分钟。你应该再次在控制台中看到如下内容:

lut 24, 2015 2:36:19 PM org.apache.catalina.core.StandardContext reload
INFO: Reloading Context with name [/ProjectVaadin] is completed

然后刷新网页。

您也可以保存所有文件 (crtl+shift+s) 按 Crtl + F5 并检查重启 tomcat。

您也可以使用 JRebel 非常好的 Eclipse 工具。

附言。 顺便提一句。不要使用旧的 Vaadin 6。
