【Activiti学习之八】Spring整合Activiti
环境
JDK 1.8
MySQL 5.6
Tomcat 8
idea
activiti 5.22
activiti-explorer是官方提供的一个演示项目，可以使用页面管理Activiti流程。activiti-explorer是以war包的形式存的。这里整合Spring+Activiti Modeler。
一、资源文件准备
1、下载activiti-5.22.0.rar
官网下载比较慢，可以从这里下载：https://pan.baidu.com/s/1XVTammPbIrbzU1MK7TBFOA
2、解压activiti-5.22.0.rar
进入wars目录，解压activiti-explorer.war demo
我们需要以下文件：
(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：传送门）
二、搭建maven web工程
这里搭建传统应用：Spring + SpringMVC + Mybatis + Activiti
1、pom.xml

log4j.appender.E.Threshold = ERROR
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern = [%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n
三、整合activiti-explorer
1、将diagram-viewer、editor-app、modeler.html拷贝到src/main/webapp下
2、将stencilset.json拷贝到/src/main/resources下
代码目录结构：
3、修改代码
(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>
这块代码用于展示流程设计器上面显示activit自带的logo，可以通过 style="display: none" 隐藏 ，也可以换成公司自己的logo。
2、修改editor-app/app-cfg.js
var ACTIVITI = ACTIVITI || {};
ACTIVITI.CONFIG = {
'contextRoot' : '/activiti',
};
修改上下文，改为应用的上下文即可。
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: ' <i class="icon icon-caret-down"></i>'
}); // Initialize angular-translate
$translateProvider.useStaticFilesLoader({
prefix: '/activiti/editor-app/i18n/',
suffix: '.json'
}); $translateProvider.preferredLanguage('zh'); // remember language
$translateProvider.useCookieStorage(); }])
上文标出的两个部分，这个是用于查询国际化文件的配置，prefix配置的是查询前缀，这里要加上应用上下文前缀，另外一个地方：$translateProvider.preferredLanguage('zh') 默认是en,改为zh:
查询的是：
4、editor-app/configuration/url-config.js

var KISBPM = KISBPM || {}; KISBPM.URL = { getModel: function(modelId) {
return ACTIVITI.CONFIG.contextRoot + '/model/' + modelId + '/json';
}, getStencilSet: function() {

这个文件是获取流程元数据json、获取流程设计器规范json、保存流程的URL地址设置，要根据你自己写的controller里的requestmapping来定，这里附上我的controller:
