运行 Java IntelliJ 2017.2.2 预发布下的 Vaadin 8.1 应用程序
Run Vaadin 8.1 app under Java 9 prerelease in IntelliJ 2017.2.2
在 IntelliJ 2017.2.2 中，我能够 运行 Vaadin 8.1.2 应用程序（全新的 vaadin-archetype-application 原型）Tomcat 8.5.20 在 Java 9+181 如果 Project Structure > Project SDK 设置为 Java 1.8。
如果 Project Structure > Project SDK 设置为 Java 9 我在 FillIn 附近收到此编译器错误，断言错误与 filling 有关Vaadin 鼠标事件。我试过谷歌搜索但没有找到任何线索。

那么，两个问题：
- IntelliJ + Vaadin + Tomcat 可以在 Java 9 下工作吗？ （即 运行ning as a Java 9 project – does indeed 运行 on Java 9 但仅作为 Java 8 项目）
- 如果是这样，在我使用全新的未修改 Vaadin 应用程序 Maven 原型的情况下，问题可能是什么？
内嵌为时间线
- 在我使用全新的未修改 Vaadin 应用程序 Maven 原型的情况下，问题可能是什么？
为了具体找出您案例的根本原因，我们肯定需要您在代码定义方面尝试的更多详细信息。
- IntelliJ + Vaadin + Tomcat 可以在 Java 9 下工作吗？*
On 22 August 2017
是。你可以使这个特定的组合起作用。在解决了我 的问题后，我终于可以使用 mvn package 到 运行 使用 tomcat 创建 war。
详情：您需要使用 Java 9 兼容版本的 Tomcat。 （apache-tomcat-9.0.0.M26 在我的例子中）并将其配置为以
开头
Using JRE_HOME: /Library/Java/JavaVirtualMachines/jdk-9.jdk/Contents/Home/
服务器启动后，您可以访问应用程序@ localhost:8080/vaadinjavanine/，其中 vaadinjavanine 是我的 tomcat 中的 war 文件名的 webapps 文件夹。
On 21 August 2017
遗憾的是，具体到组合的答案仍然是否。我相信还不可能使这种组合起作用。
码头服务器
这是我更新的 sample application 在我的 localhost:8080 上与 IntelliJ + Vaadin + Jetty 一起工作使用 Jetty 服务器，无论我的项目 SDK 设置为 Java1.8 还是 Java9。它的工作原理是这样的：
这是在克服 #jetty.project/1758 by upgrading to the 6.0_BETA of asm and asm-commons libraries and using the custom 9.4.7-SNAPSHOT built on my local used in the project(commit - #e34415 之后获得的。)
Tomcat服务器
按照创建 war 的推荐方法，我使用以下命令创建了应用程序 war（在我的例子中是 <finalName>vaadinjavanine</finalName>）：
mvn package
确保 CATALINA_HOME/webapps 包含此文件。基本复制了。
- 在默认端口上启动 tomcat 以访问应用程序的 url：
localhost:8080/vaadinjavanine/
但最终在当前链中发现了另一个问题：
On 20 August 2017
问题的答案是否。
我所做的是，在 getting started guide 之后，尝试从头开始创建基于 java9 的基于 maven 的 vaadin 应用程序。使用以下配置：
apache-tomcat-8.0.22
intelliJ-IDEA 2017.2.2
<vaadin.version>8.1.2</vaadin.version>
