Play Framework - 环境搭建(2.2)

下载安装：

    由于楼主是windows平台，所以mac的朋友们请看官方安装步骤哟。https://www.playframework.com/documentation/2.2.x/Installing

    pre1：jdk6+的版本http://www.oracle.com/technetwork/java/javase/downloads/index.html

    pre2：eclispe版本下载：http://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/marsr

    1.到https://downloads.typesafe.com/play/2.2.6/play-2.2.6.zip下载play 2.2.6安装包。

    2.解压zip到xx目录，得到xx\play-2.2.6 的目录。设置环境变量

    点击计算机 - 属性

    

  2.点击高级系统设置

3.点击环境变量

        4.点击新建

    

            5.设置环境变量，注意不要加“；”

            

            6.找到Path，点击编辑

    

7.输入";%PLAY%;"注意分号。

8.验证Path&Play

创建第一个Demo：

    1. play new [direaction]

    调出CMD输入 play new myNews //默认为当前路径，

    要是想创建到其他路径，需要写入全路径比如：E:\workspace-main\j2ee\myNews

    

    2.输入application name，这里同样输入myNews

    3.输入2（“ 2             - Create a simple Java application”）

    

    4.创建完毕。

    

项目目录结构：

    └ classes_managed    → Managed class files (templates, ...)
    └ resource_managed   → Managed resources (less, ...)
    └ src_managed        → Generated sources (templates, ...)
test                     → source folder for unit or functional tests

运行myNews：

    1.打开cmd，cd到创建项目的目录下

    

    2.输入 play，初始化项目，等到出现"[myNews] $"就OK了。

    

    3.输入 run，就开始解析资源，然后启动9000的端口了。输入http://localhost:9000/就可以访问myNews了

    第一次貌似访问有点慢，貌似在编译一些东西。（红框的部分是第一次访问参数的日志）

    

    4.输入ctrl+d 停止web application的运行。

   

关联到Eclipse：

    1.打开cmd ，cd到创建的工程myNews。

    2.输入eclipse

    

    打开刚才的工作空间发现，产生了如下文件：

    3.打开eclispe，导入myNews，发现工程如下，发现引用的lib太多了，稍后我们滴4步优化下。

    

    4.在eclipse，打开window，选中prefence，依次展开Java->Build Path->User Libraries,点击右边的New，输入PLAY_LIBS点击OK。

    

    5.在%eclips_workspace%\.metadata\.plugins\org.eclipse.core.runtime\.settings

     %eclips_workspace%代表你的工作空间。比如我的是E:\workspace-main\j2ee

     那么我的路径就是：E:\workspace-main\j2ee\.metadata\.plugins\org.eclipse.core.runtime\.settings

    找到并打开“org.eclipse.jdt.core.prefs”

    

    末尾添加：

    如果你的play路径不是“E:\IDE-OTHRE\play-2.2.6”你需要添加如下替换假设你的路径是X:Y\Z：

    那么需要全部替换"X\:/Y/Z",此处注意盘符后有个\，并且替换的时候不需要选择正则表达式匹配

    

    最终效果是这个样子：

    

    6.重新打开Eclipse，点击myNews右键Build Path -> Configure Build Path ，选中所以的LIB，remove

    

    7.在6的基础上，点击 Add Libraries，选中User Library，选择我们刚才新建的“PLAY_LIBS”，点击OK

    8.点击myNews右键Build Path -> Configure Build Path ，点击Add Class Folder，

    选择myNews/target/scale-2.0/classes_managed，点击OK

    

        

    9.build 该项目。不会报错就成了了

    

总结：

    过程比较繁琐，也不知道有更好的方式没有，如有的话，请道友指点下。
