Java 将 Tomcat 9 添加到 Eclipse

Add Tomcat 9 to eclipse

提问by jamesdeath123

I have downloaded and installed tomcat 9 to my machine, but on Eclipse > Window > Preferences > Server > Runtime Environment, after clicking on Add, I see only Tomcat 7 and Tomcat 8, but not Tomcat 9.

我已经将 tomcat 9 下载并安装到我的机器上，但是在 Eclipse > Window > Preferences > Server > Runtime Environment 上，单击 Add 后，我只看到 Tomcat 7 和 Tomcat 8，但没有看到 Tomcat 9。

What I have done: 1) installed tomcat 9 to local server; 2) updated eclipse to Mars (latest as of 2015-11-25); 3) installed eclipse "JST Server Adapters" and "JST Server Adapters Extensions"

我做了什么：1）将tomcat 9安装到本地服务器；2) 更新到火星的日食（最新至 2015-11-25）；3）安装eclipse“JST Server Adapters”和“JST Server Adapters Extensions”

Note: My purpose of using tomcat 9 is it seems to be the only version that explicitly support java 8 and later, and my web app is using java 8. (http://tomcat.apache.org/whichversion.html) I also have tomcat 7 exist in project but I also want to keep it in the machine, not to delete it.

注意：我使用 tomcat 9 的目的是它似乎是唯一明确支持 java 8 及更高版本的版本，而我的网络应用程序使用的是 java 8。（http://tomcat.apache.org/whichversion.html）我也项目中存在tomcat 7，但我也想将其保留在机器中，而不是删除它。

There are two things to note here:

这里有两点需要注意：

• Tomcat 9 is not released yet.Not a final version that is. If you check the official website, you will see that the only available version is an M1 version. Hence there is no support from Eclipse WTP for this early version. It will come soon, but not yet.

• Tomcat 9 is not the only version that explicitly supports Java 8.If you check this page, you will see that "Supports Java version: 8 and later", which in this context means, that it officially support only Java 8 and above. It does notmean however this is the only one supporting Java 8. Theoretically you should be able to use any Tomcat version, in practice a Tomcat 8 will work perfectly well, since it support Java 7 and above. The majority of people with a Java8 + Tomcat combination are using Tomcat 8. Tomcat 8 also has Eclipse WTP support.

• Tomcat 9 尚未发布。不是最终版本。如果您查看官方网站，您会看到唯一可用的版本是M1版本。因此，Eclipse WTP 不支持此早期版本。它很快就会到来，但还没有。

• Tomcat 9 并不是唯一明确支持 Java 8 的版本。如果您查看此页面，您将看到“支持 Java 版本：8 及更高版本”，在此上下文中，这意味着它正式仅支持 Java 8 及更高版本。它并不意味着然而，这是唯一一个支持Java 8理论上你应该能够使用任何Tomcat的版本，在实践中的Tomcat 8将会很好地工作，因为它支持Java 7及以上。大多数拥有 Java8 + Tomcat 组合的人都在使用 Tomcat 8。Tomcat 8 还具有 Eclipse WTP 支持。
