環境

　　JDK 1.8
　　MySQL 5.6
　　Tomcat 8
　　idea
　　activiti 5.22

activiti-explorer是官方提供的一個演示項目，可以使用頁面管理Activiti流程。activiti-explorer是以war包的形式存的。這里整合Spring+Activiti Modeler。

一、資源文件准備
1、下載activiti-5.22.0.rar
官網下載比較慢，可以從這里下載：https://pan.baidu.com/s/1XVTammPbIrbzU1MK7TBFOA

2、解壓activiti-5.22.0.rar

進入wars目錄，解壓activiti-explorer.war demo

我們需要以下文件：

(1)diagram-viewer、editor-app、modeler.html
(2)stencilset.json（原版的title、description描述都是英文，可以改成中文：傳送門）

二、搭建maven web工程
這里搭建傳統應用：Spring + SpringMVC + Mybatis + Activiti
1、pom.xml

三、整合activiti-explorer

1、將diagram-viewer、editor-app、modeler.html拷貝到src/main/webapp下
2、將stencilset.json拷貝到/src/main/resources下

代碼目錄結構：

3、修改代碼

(1)modeler.html

<div style="display: none" class="navbar navbar-fixed-top navbar-inverse" role="navigation" id="main-header">
        <div class="navbar-header">
            <a href="" ng-click="backToLanding()" class="navbar-brand"
               title="{{'GENERAL.MAIN-TITLE' | translate}}"><span
                    class="sr-only">{{'GENERAL.MAIN-TITLE' | translate}}</span></a>
        </div>
    </div>

這塊代碼用於展示流程設計器上面顯示activit自帶的logo，可以通過 style="display: none" 隱藏，也可以換成公司自己的logo。

2、修改editor-app/app-cfg.js

var ACTIVITI = ACTIVITI || {};
ACTIVITI.CONFIG = {
        'contextRoot' : '/activiti',
    };

修改上下文，改為應用的上下文即可。

3、修改editor-app/app.js

activitiModeler
  // Initialize routes
  .config(['$selectProvider', '$translateProvider', function ($selectProvider, $translateProvider) {

      // Override caret for bs-select directive
      angular.extend($selectProvider.defaults, {
          caretHtml: '&nbsp;<i class="icon icon-caret-down"></i>'
      });
        
        // Initialize angular-translate
        $translateProvider.useStaticFilesLoader({
            prefix: '/activiti/editor-app/i18n/',
            suffix: '.json'
        });

        $translateProvider.preferredLanguage('zh');

        // remember language
        $translateProvider.useCookieStorage();
        
  }])

上文標出的兩個部分，這個是用於查詢國際化文件的配置，prefix配置的是查詢前綴，這里要加上應用上下文前綴，另外一個地方：$translateProvider.preferredLanguage('zh') 默認是en,改為zh:

查詢的是：

4、editor-app/configuration/url-config.js

 */
var KISBPM = KISBPM || {};

KISBPM.URL = {

    getModel: function(modelId) {
        return ACTIVITI.CONFIG.contextRoot + '/model/' + modelId + '/json';
    },

    getStencilSet: function() {
        return ACTIVITI.CONFIG.contextRoot + '/editor/stencilset?version=' + Date.now();
    },

    putModel: function(modelId) {
        return ACTIVITI.CONFIG.contextRoot + '/model/' + modelId + '/save';
    }
};

這個文件是獲取流程元數據json、獲取流程設計器規范json、保存流程的URL地址設置，要根據你自己寫的controller里的requestmapping來定，這里附上我的controller:
