activiti 5.14 activitimodeler與業務系統整合（業務系統為spring，struts2，mybatis結構）

網上各種查資料，各種沒有，最多的一片文章是咖啡兔的大作，基於spring MVC與marven，與我整合的業務系統差別較大，且activiti是5.12版本，其他文章基本都是抄來抄去，後面終於自己整了出來，整合內容存在冗餘，目錄結構不合理，本文暫不考慮，我還沒整理清楚，記錄下整理步驟：

（1）下載activiti 5.14，下載完成後，找到此檔案，activiti-5.14\wars\activiti-explorer.war,解壓後目錄結構如下，（war包解壓java cvf 命令）

（2）把除“WEB_INFO”以外的檔案先不加處理的仍到項目的WebRoot檔案夾下

（3）後修改spring設定檔

添加如下配置：

<!-- 流程引擎基礎配置開始 -->
<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
<property name="dataSource" ref="dataSource" />
<!-- Database configurations -->
<property name="databaseSchemaUpdate" value="true" />
<!-- job executor configurations -->
<property name="jobExecutorActivate" value="false" />
<property name="transactionManager" ref="transactionManager"/>
<property name="deploymentResources" value="classpath*:/diagrams/*/*.bpmn"/>   
<!-- font -->
        <property name="activityFontName" value="宋體"/>
        <property name="labelFontName" value="宋體"/>
</bean>
<bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">
<property name="processEngineConfiguration" ref="processEngineConfiguration"/>
</bean>
<bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService" />
<bean id="runtimeService" factory-bean="processEngine" factory-method="getRuntimeService" />
<bean id="taskService" factory-bean="processEngine" factory-method="getTaskService" />
<bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService" />
<bean id="managementService" factory-bean="processEngine" factory-method="getManagementService" />
<bean id="identityService" factory-bean="processEngine" factory-method="getIdentityService"/>
<bean id="formService" factory-bean="processEngine" factory-method="getFormService" />
    <!-- 流程引擎基礎配置結束 --> 

（4）再次開啟解壓出來的war包檔案，找到“WEB-INF\classes”下面的所有設定檔，不加修改的仍到項目系統對應的目錄下，保證項目編譯完成後在WEB-INF\classes下能找到該檔案。

（5）修改web.xml檔案

activiti modeler採用servlet的方式，可以採用自己手寫過濾器的方式進行過濾攔截，也可以直接修改struts在web.xml的配置實現，個人直接修改設定檔

如上圖所示，添加過濾攔截，此處根據不同的原系統配置需要做不同的實現，目前本人業務系統action之間的跳轉都是通過.action的方式。

（6）在web.xml下添加如下內容

<servlet>
    <servlet-name>RestletServlet</servlet-name>
    <servlet-class>org.restlet.ext.servlet.ServerServlet</servlet-class>
    <init-param>
        <!-- Application class name -->
        <param-name>org.restlet.application</param-name>
        <param-value>org.activiti.rest.explorer.application.ExplorerRestApplication</param-value>
    </init-param>
</servlet>
 
<!-- Catch all service requests -->
<servlet-mapping>
    <servlet-name>RestletServlet</servlet-name>
    <url-pattern>/service/*</url-pattern>
</servlet-mapping>

（7）添加jar檔案，將下載到的activiti包activiti-5.14\libs下的所有jar檔案匯入到業務系統中。

（8）反編譯WEB-INF\classes下相關類，總共沒幾個很好反編譯。還原war包下此處的所有class檔案，最終將相關檔案按照原目錄結構全部copy到業務系統中，結構如下

（9）寫一個action類，建立流程

package com.boyun.activiti.base.action;


import org.activiti.engine.FormService;
import org.activiti.engine.HistoryService;
import org.activiti.engine.IdentityService;
import org.activiti.engine.ProcessEngine;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.TaskService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;
import org.activiti.explorer.demo.DemoDataGenerator;
import java.io.ByteArrayInputStream;
import java.util.List;






import org.activiti.editor.constants.ModelDataJsonConstants;
import org.activiti.engine.repository.Model;
import org.apache.commons.lang3.StringUtils;
import org.codehaus.jackson.map.ObjectMapper;
import org.codehaus.jackson.node.ObjectNode;


import com.boyun.action.BaseAction;
@Scope("prototype")
@Controller("baseActivitiAction")
public class BaseActivitiAction extends BaseAction{
/**
* 
*/
private static final long serialVersionUID = 1L;
@Autowired
ProcessEngine processEngine;
@Autowired
RepositoryService repositoryService;
@Autowired
TaskService taskService;
@Autowired
RuntimeService runtimeService;
@Autowired
protected IdentityService identityService;
@Autowired
private FormService formService;
@Autowired
private HistoryService historyService;
public String createActiviti(){
try {
ObjectMapper objectMapper = new ObjectMapper();
ObjectNode editorNode = objectMapper.createObjectNode();
     editorNode.put("id", "canvas");
     editorNode.put("resourceId", "canvas");
     ObjectNode stencilSetNode = objectMapper.createObjectNode();
     stencilSetNode.put("namespace", "http://b3mn.org/stencilset/bpmn2.0#");
     editorNode.put("stencilset", stencilSetNode);
     Model modelData = repositoryService.newModel();
 
     ObjectNode modelObjectNode = objectMapper.createObjectNode();
     modelObjectNode.put(ModelDataJsonConstants.MODEL_NAME, "name");
     modelObjectNode.put(ModelDataJsonConstants.MODEL_REVISION, 1);
    String description = StringUtils.defaultString("description");
     modelObjectNode.put(ModelDataJsonConstants.MODEL_DESCRIPTION, description);
     modelData.setMetaInfo(modelObjectNode.toString());
     modelData.setName("name");
     modelData.setKey(StringUtils.defaultString("key"));
 
     repositoryService.saveModel(modelData);
     repositoryService.addModelEditorSource(modelData.getId(), editorNode.toString().getBytes("utf-8"));
 
     this.getResponse().sendRedirect(this.getRequest().getContextPath() + "/service/editor?id=" + modelData.getId());
}catch(Exception e){
e.printStackTrace();
}
return null;
}
private String modelId;

 
}

（10）將此類按照正常struts配置，完成後訪問此類，建立完成，後直接跳轉到編輯頁面"    this.getResponse().sendRedirect(this.getRequest().getContextPath() + "/service/editor?id=" + modelData.getId());",

跳轉完成後如下圖所示，下圖已經漢化完成，預設展示的是英文版本。
