webapp-runner使用指南

webapp-runner 可以在任何安装有 JRE 环境的系统中利用 Tomcat 将应用程序启动。使用 webapp-runner 不需要安装 Tomcat。它只是一个 jar 文件可以用java命令运行和配置。Rainbond 运行 War 包、或 Maven 打包成 War 包的项目都默认使用 webapp-runner。

版本说明

Webapp Runner 是基于 Tomcat server 的。默认 Rainbond 支持的版本如下:

高级特性配置

目前 Rainbond 提供的 Webapp-runner 都支持 session 管理.

session 管理

# Procfile
$ java -jar ./webapp-runner.jar --session-store memcache target/<appname>.war

然后确保有三个环境变量可供配置 MEMCACHE_SERVERS, MEMCACHE_USERNAME, MEMCACHE_PASSWORD

或者

# Procfile
java -jar ./webapp-runner.jar --session-store redis target/<appname>.war

然后确保 Redis 环境变量可用于配置：REDIS_URL

设置访问路径

# Procfile
java -jar ./webapp-runner.jar --path /phone target/<appname>.war
