JRuby1.5.1下运行Rails2.2.2应用

最近要把我的一个RoR项目卖给客户,为了进行产权保护,研究了一下JRuby的打包,记录如下

下载/安装JRuby
- JRuby 下载地址 http://jruby.org/download
- 下载Windows版本,然后安装到C盘下
  - 安装的时候自动设置PATH,方便不少.
  - 运行 jruby -v 验证安装成功
安装Rails 2.2.2
1. jruby -S gem install rails -v 2.2.2
安装JDBC驱动
1. JDBC
  - jruby -S gem install activerecord-jdbc-adapter
2. Sqlite3
  - jruby -S gem install activerecord-jdbcsqlite3-adapter
3. MySQL
  - jruby -S gem install activerecord-jdbcmysql-adapter
安装Sqlite3数据库
1. 下载Sqlit3
2. 放置sqlite3.exe和sqlite3.dll到JRUBY/bin下
建立Rails 项目
- > jruby -S rails myapp
- > cd myapp
- # 生成一个界面
- > jruby script/generate scaffold post title:string body:text published:boolean
- #创建数据库，如果失败，检查sqlite3.exe是否在PATH中
- > jruby -S rake db:create
- #导入数据
- > jruby -S rake db:migrate
- #启动服务器
- > jruby script/server
- #测试地址1
- http://localhost:3000
- #测试地址2
- http://localhost:3000/posts
修改config
1. myapp/config/database.yml
2. development: adapter: jdbcsqlite3 database: db/development.sqlite3 pool: 5 timeout: 5000
利用warbler打包
- 安装
- > jruby -S gem install warbler
- 生成config配置
- > jruby -S warble config
- 修改warble.rb配置
- # You can also use regexps or Gem::Dependency objects for flexibility or # fine-grained control. # config.gems << /^merb-/ # config.gems << Gem::Dependency.new("merb-core", "= 0.9.3") #追加一下代码 %w{activerecord-jdbcsqlite3-adapter activerecord-jdbc-adapter}.each{|g| config.gems << g}
- 生成war包
- > jruby -S warble war
- 把生成的myapp.war放在tomcat下运行。
- 虽然可以在Tomcat下运行Rails程序，但是打开War包一看,还是rb代码。所以还要用AOT模式重新打一次
利用warbler进行AOT模式打包
1. 下载唐力群修改过得warbler包，地址为 http://github.com/crazycode/warbler
2. 下载后解压缩，覆盖C:/jruby-1.5.1/lib/ruby/gems/1.8/gems/warbler-1.1.0下内容
3. 执行warble -T,会多出war:aot
4. rake config # Generate a configuration file to customize your w... rake pluginize # Unpack warbler as a plugin in your Rails application rake version # Display version of warbler rake war # Create Administrator.war rake war:aot # Create AOT Administrator.war rake war:app # Copy all application files into the .war rake war:clean # Clean up the .war file and the staging area rake war:compile # Compile rails code, and patch activesupport rake war:exploded # Create an exploded war in the app's public directory rake war:gems # Unpack all gems into WEB-INF/gems rake war:jar # Run the jar command to create the .war rake war:java_classes # Copy java classes into the .war rake war:java_libs # Copy all java libraries into the .war rake war:public # Copy all public HTML files to the root of the .war rake war:war:java_libs # Copy all java libraries into the .war rake war:webxml # Generate a web.xml file for the webapp
5. 如果你不是Rails2.3.2的话还需要修改C:/jruby-1.5.1/lib/ruby/gems/1.8/gems/warbler-1.1.0/lib/warbler/task.rb文件
6. def define_compile_task with_namespace_and_config do |name, config| desc "Compile rails code, and patch activesupport" task "compile" do # replace lib/active_support/dependencies.rb with patched version cp "#{File.dirname(__FILE__)}/dependencies-2.2.2.rb", "#{@config.staging_dir}/WEB-INF/gems/gems/activesupport-2.2.2/lib/active_support/dependencies.rb" # jrubyc all app file. Dir["#{@config.staging_dir}/WEB-INF/app/**/*.rb"].each do |file| rm file end sh "jrubyc app -t #{@config.staging_dir}/WEB-INF" end end end
7. 执行 > jruby -S warble war:aot
8. 生成war包。并且里面只有class
9. 唐力群修改过的包提供了2.2.2/2.3.2两个版本的dependencies.rb的修改。如果不是这两个版本的rails，则需要自行修改dependencies.rb. 参考如下
