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:

web服务支持web服务版本自定义Procfile中jar文件名
tomcat7webapp-runner-7.0.91.0.jarwebapp-runner.jar
tomcat8webapp-runner-8.0.52.0.jarwebapp-runner.jar
tomcat85 (默认)webapp-runner-8.5.38.0.jarwebapp-runner.jar
tomcat9webapp-runner-9.0.16.0.jarwebapp-runner.jar
jetty7jetty-runner-7.5.4.v20111024.jarjetty-runner.jar
jetty9jetty-runner-9.4.0.v20161208.jarjetty-runner.jar

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
