activiti 5.14 activitimodeler与业务系统集成（业务系统为spring，struts2，mybatis结构）

2014-10-30 12:08 513 查看
网上各种查资料，各种没有，最多的一片文章是咖啡兔的大作，基于spring MVC与marven，与我集成的业务系统差别较大，且activiti是5.12版本，其他文章基本都是抄来抄去，后面终于自己整了出来，集成内容存在冗余，目录结构不合理，本文暂不考虑，我还没整理清楚，记录下整理步骤：

（1）下载activiti 5.14，下载完成后，找到此文件，activiti-5.14\wars\activiti-explorer.war,解压后目录结构如下，（war包解压java cvf 命令）






（2）把除“WEB_INFO”以外的文件先不加处理的仍到项目的WebRoot文件夹下






（3）后修改spring配置文件

添加如下配置：

<!-- 流程引擎基础配置开始 -->

<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="宋体"/>

<property name="labelFontName" value="宋体"/>

</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" />

<!-- 流程引擎基础配置结束 -->



（4）再次打开解压出来的war包文件，找到“WEB-INF\classes”下面的所有配置文件，不加修改的仍到项目系统对应的目录下，保证项目编译完成后在WEB-INF\classes下能找到该文件。






（5）修改web.xml文件

activiti modeler采用servlet的方式，可以采用自己手写过滤器的方式进行过滤拦截，也可以直接修改struts在web.xml的配置实现，个人直接修改配置文件

如上图所示，添加过滤拦截，此处根据不同的原系统配置需要做不同的实现，目前本人业务系统action之间的跳转都是通过.action的方式。

（6）在web.xml下添加如下内容

<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文件，将下载到的activiti包activiti-5.14\libs下的所有jar文件导入到业务系统中。

（8）反编译WEB-INF\classes下相关类，总共没几个很好反编译。还原war包下此处的所有class文件，最终将相关文件按照原目录结构全部copy到业务系统中，结构如下











（9）写一个action类，创建流程

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）将此类按照正常struts配置，完成后访问此类，创建完成，后直接跳转到编辑页面" this.getResponse().sendRedirect(this.getRequest().getContextPath() + "/service/editor?id=" + modelData.getId());",

跳转完成后如下图所示，下图已经汉化完成，默认展示的是英文版本。
