如何嵌入Tomcat 6? [英] How to embed Tomcat 6?

问题描述

我目前正在生产环境中在 Tomcat 6 上运行我的 web 应用程序，并想评估在嵌入式模式下运行 Tomcat.

I'm currently running my webapps on Tomcat 6 in production, and would like to evaluate running Tomcat in embedded mode.

除了 api 文档?

推荐答案

代码不言自明.查看 pom.xml 片段和运行 tomcat 的类.

Code speaks for itself. See the pom.xml snippet and the class to run tomcat.
