【技术文档】Jeecg-P3开发环境搭建入门（java插件开发框架）

一、项目工程说明

jeecg-p3-web | 启动主项目 jeecg-p3-biz-demo | 插件项目 注意：项目为maven工程，采用maven方式导入eclipse等IDE开发工具 标准开发工具：eclipse + jdk7 + tomcat7 + mysql

二、开发环境搭建入门

第一步：创建Mysql数据库jeecg-p3(UTF-8编码)，执行数据库脚本

脚本位置：jeecg-p3-web/doc/sql/jeecg-p3-mysql.sql

[1].注意编码选择：

<ignore_js_op style="word-wrap: break-word;"><img id="aimg_1617" aid="1617" src="http://www.jeecg.org/data/attachment/forum/201603/23/094542oqy74s7s7sfs9gs7.png" zoomfile="data/attachment/forum/201603/23/094542oqy74s7s7sfs9gs7.png" file="data/attachment/forum/201603/23/094542oqy74s7s7sfs9gs7.png" class="zoom" width="406" inpost="1" alt="1.png" title="1.png" initialized="true" style="word-wrap: break-word; cursor: pointer;"></ignore_js_op>

[2].脚本执行成功，生成两个测试表

<ignore_js_op style="word-wrap: break-word;"><img id="aimg_1618" aid="1618" src="http://www.jeecg.org/data/attachment/forum/201603/23/094621yelbp4pneohee8z8.png" zoomfile="data/attachment/forum/201603/23/094621yelbp4pneohee8z8.png" file="data/attachment/forum/201603/23/094621yelbp4pneohee8z8.png" class="zoom" width="600" inpost="1" alt="2.png" title="2.png" initialized="true" style="word-wrap: break-word; cursor: pointer;"></ignore_js_op>

第二步：启动项目方法 (jeecg-p3-web)

• 方式一：快捷启动方式（前提先创建数据库，执行脚本）
  

步骤：直接双击运行jeecg-p3-web\bin\run-tomcat7.bat或bin\run-tomcat.bat

->启动Web服务器（第一次运行，需要下载依赖jar包，请耐心等待）。

-> 启动成功，直接进入第三步，访问测试地址

• 方式二：elipse采用maven方式（前提先创建数据库，执行脚本）
  

[1].按照顺序依次install{jeecg-p3-pom}{jeecg-p3-biz-demo}

提醒：很重要，如果不install，会报依赖包仓库找不到的错误。

[2].启动web项目

a. Web项目右建->debug as->debug configurations->选中jeecg-p3-web项目->输入命令：tomcat:run

注意：update snapshots需要选中，官方会不断更新底层包

<ignore_js_op style="word-wrap: break-word;"><img id="aimg_1619" aid="1619" src="http://www.jeecg.org/data/attachment/forum/201603/23/095652agffh3fffgfxxg4p.jpg" zoomfile="data/attachment/forum/201603/23/095652agffh3fffgfxxg4p.jpg" file="data/attachment/forum/201603/23/095652agffh3fffgfxxg4p.jpg" class="zoom" width="600" inpost="1" alt="3.jpg" title="3.jpg" initialized="true" style="word-wrap: break-word; cursor: pointer;"></ignore_js_op>

b. 点击debug启动，看到以下截图表明启动成功

<ignore_js_op style="word-wrap: break-word;"><img id="aimg_1620" aid="1620" src="http://www.jeecg.org/data/attachment/forum/201603/23/095918ra5zgaex11ljg6dk.png" zoomfile="data/attachment/forum/201603/23/095918ra5zgaex11ljg6dk.png" file="data/attachment/forum/201603/23/095918ra5zgaex11ljg6dk.png" class="zoom" width="600" inpost="1" alt="4.png" title="4.png" initialized="true" style="word-wrap: break-word; cursor: pointer;"></ignore_js_op>

第三步：访问测试地址

1.http://localhost/jeecg-p3-web/p3/wxActInvite.do?list

2.http://localhost/jeecg-p3-web/p3/auth.do?list

第四步：截图演示

a. 树列表

<ignore_js_op style="word-wrap: break-word;"><img id="aimg_1621" aid="1621" src="http://www.jeecg.org/data/attachment/forum/201603/23/095956tcm1n0nhmcyyy6hu.png" zoomfile="data/attachment/forum/201603/23/095956tcm1n0nhmcyyy6hu.png" file="data/attachment/forum/201603/23/095956tcm1n0nhmcyyy6hu.png" class="zoom" width="600" inpost="1" alt="5.png" title="5.png" initialized="true" style="word-wrap: break-word; cursor: pointer;"></ignore_js_op>

b.普通列表

<ignore_js_op style="word-wrap: break-word;"><img id="aimg_1622" aid="1622" src="http://www.jeecg.org/data/attachment/forum/201603/23/100047b2ddt2sika4paxta.png" zoomfile="data/attachment/forum/201603/23/100047b2ddt2sika4paxta.png" file="data/attachment/forum/201603/23/100047b2ddt2sika4paxta.png" class="zoom" width="600" inpost="1" alt="6.png" title="6.png" style="word-wrap: break-word; cursor: pointer;"></ignore_js_op>

第五步：jeecg项目集成插件方法

[1]. 第一步采用maven直接引入

<ignore_js_op style="word-wrap: break-word;"><img id="aimg_1623" aid="1623" src="http://www.jeecg.org/data/attachment/forum/201603/23/100118xp5tkdp5p54ii4ii.png" zoomfile="data/attachment/forum/201603/23/100118xp5tkdp5p54ii4ii.png" file="data/attachment/forum/201603/23/100118xp5tkdp5p54ii4ii.png" class="zoom" width="600" inpost="1" alt="7.png" title="7.png" initialized="true" style="word-wrap: break-word; cursor: pointer;"></ignore_js_op>

[2].在jeecg库，执行插件SQL脚本

[3].配置插件功能访问菜单

<ignore_js_op style="word-wrap: break-word;"><img id="aimg_1624" aid="1624" src="http://www.jeecg.org/data/attachment/forum/201603/23/100147b8at1fhay91707fv.png" zoomfile="data/attachment/forum/201603/23/100147b8at1fhay91707fv.png" file="data/attachment/forum/201603/23/100147b8at1fhay91707fv.png" class="zoom" width="600" inpost="1" alt="8.png" title="8.png" initialized="true" style="word-wrap: break-word; cursor: pointer;"></ignore_js_op>

[4].截图演示

<ignore_js_op style="word-wrap: break-word;"><img id="aimg_1625" aid="1625" src="http://www.jeecg.org/data/attachment/forum/201603/23/100217ysxs1kkf18tucfmw.png" zoomfile="data/attachment/forum/201603/23/100217ysxs1kkf18tucfmw.png" file="data/attachment/forum/201603/23/100217ysxs1kkf18tucfmw.png" class="zoom" width="600" inpost="1" alt="9.png" title="9.png" initialized="true" style="word-wrap: break-word; cursor: pointer;"></ignore_js_op>

第六步：jeecg-p3代码生成器使用

工具类： jeecg-p3-web/src/main/java/util/P3CodeGenerateUtil.java

配置文件：jeecg-p3-web/src/main/resources/p3-cg-config.properties

代码生成器模板位置：jeecg-p3-web/src/main/resources/p3/cg/template/ftl（不做二次开发，不需要修改模板文件）
