SpringMVC与Activiti网页流程设计器整合

https://blog.csdn.net/qq_30270931/article/details/79267279

1.官方例子研究

Activiti给出的官方例子activiti-explorer中有一个网页版的流程设计器，看起来很不错的样子。考虑到以后的工作中，可能会涉及到用户自己设计流程，这样的话，会要用到网页版的流程设计器，因此，想办法吧这个官网的网页设计器从activiti-explorer工程中分离出来，与SpringMvc集成在一起，这样以后就可以在自己的项目中直接设计流程，然后发布运行了，不需要在Eclipse的Activiti插件中先将流程设计好，再导入项目中这么麻烦了，而且后期的修改和维护更加的方便。我们先可以看一下activiti-explorer的例子中流程设计器的样子。

从官网上下载Activiti 5.18.0的压缩包，下载地址: http://www.activiti.org/download.html 。

将压缩包解压到任一目录下。我们可以看到Activiti的目录结构

Database是存放Activiti需要用到的数据库的各个版本的数据库脚本。打开到具体的目录我们可以看到，Activiti支持的数据库包括h2，Mysql，Oracle，Postgre，db2，SQL Server。

Docs中存放的是Activiti的参考文档，都是网页版的形式，里面有一些使用API的文档可以参考使用。

Libs中存放的是Activiti需要用到的各种jar包，以后若差什么jar包找不到，可以在这里面查找添加到工程中。

Wars里面放的是Activiti的两个例子工程，将这两个工程放到一个tomcat的webapp目录下，运行tomcat就可以看到Activiti运行的整个过程。

将wars中的activiti-explorer.war 复制到一个tomcat的webapp目录下，启动tomcat。在浏览器中输入 http://localhost:8080/activiti-explorer/，我们可以看到Activiti的登录界面

使用账户 kermit/kermit 登录系统，切换到流程便签，我们可以看到系统中已经有的几个流程的例子。

点击此页面上的“流程设计工作区”，点击“新建模型”，填写名称，描述后点击创建。

之后，系统会跳转到流程设计的界面上。

在左侧工具栏中拖动控件到右边的工作区，给各个模块去一个名字之后，将流程用箭头有机连接在一起，就行成了一个完整的工作流，以下是一个简单的财务报销的流程。流程开始后，先要流程申请人提交财务报销申请，提交完成之后，靖经理审批，财务审批，审批完成之后进入财务报销环节，财务报销之后，整个流程结束。十分的简单明了。

2. 搭建SpringMVC框架。

2.1. 添加依赖文件

新建Maven工程，取名为demo。在demo的pom文件中加入springMvc的依赖包，maven依赖如下。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2.2 配置spring-mvc.xml文件

在demo工程的src/main/resources下新建spring-mvc.xml文件，在文件中加入以下内容。

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beans

<property name="prefix" value="/" />

<property name="suffix" value=".jsp" />

</bean>

</beans>

2.3 Spring与Hibernate集成

在demo工程的src/main/resources目录下新建spring-hibernate.xml文件，向文件中添加以下内容。

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"

xmlns:aop="http://www.springframework.org/schema/aop"

xsi:schemaLocation="

<property name="minPoolSize" value="5" />

<property name="maxPoolSize" value="20" />



<property name="acquireIncrement" value="5" />

</bean>



<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">



<property name="dataSource" ref="dataSource" />



<property name="hibernateProperties">

</props>

</property>



<property name="packagesToScan" value="com.fh.server.api.entity" />

</bean>



<bean id="transactionManager"

class="org.springframework.orm.hibernate4.HibernateTransactionManager">

<property name="sessionFactory" ref="sessionFactory" />

</bean>



<tx:advice id="transactionAdvice" transaction-manager="transactionManager">



<tx:attributes>

<tx:method name="insert*" propagation="REQUIRED" />

<tx:method name="update*" propagation="REQUIRED" />

<tx:method name="find*" propagation="SUPPORTS" read-only="true" />

<tx:method name="select*" propagation="SUPPORTS" read-only="true" />

<tx:method name="load*" propagation="SUPPORTS" read-only="true" />



<tx:method name="*" />

</tx:attributes>

</tx:advice>



<aop:config>



<aop:pointcut id="transactionPointcut"

expression="execution(* com.fh.server.service..*Impl.*(..))" />



<aop:advisor pointcut-ref="transactionPointcut"

advice-ref="transactionAdvice" />

</aop:config>

</beans>

配置完这些之后，还要在src/main/resources目录下新建ehcache.xml文件，来配置hibernate的二级缓存。向ehcache.xml中加入以下内容

<?xml version="1.0" encoding="UTF-8"?>

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../config/ehcache.xsd">

<diskStore path="c:/ehcache" />



     <defaultCache

            maxElementsInMemory="1000"

            eternal="false"

            timeToIdleSeconds="120"

            timeToLiveSeconds="120"

            maxElementsOnDisk="1000000"

            overflowToDisk="true"

            memoryStoreEvictionPolicy="LRU">



    </defaultCache>



<cache

     name="org.andy.work.entity.AcctUser"

maxElementsInMemory="2"

memoryStoreEvictionPolicy="LRU"

eternal="true"

diskPersistent="false"

overflowToDisk="false"

maxElementsOnDisk="1000000" />

</ehcache>

2.4配置spring.xml文件

在demo的src/main/resources目录下新建spring.xml文件，向其中加入以下内容。

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-4.1.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.1.xsd">



<context:property-placeholder location="classpath:config.properties"/>



<context:component-scan base-package="com.fh.server.service.impl,com.fh.server.dao.impl" />

</beans>

2.5 配置demo工程的web.xml文件

在demo工程的src/main/webapp目录下新建WEB-INF文件夹，在WEB-INF文件夹中新增web.xml文件，向web.xml文件中加入以下内容。

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

id="WebApp_ID" version="2.5">

</welcome-file-list>

</web-app>

至此，我们已经搭建好了SpringMVC+Spring+Hibernate的框架。可以将项目部署到tomcat下，启动tomcat在浏览器中输入http://localhost:8080/demo, 就可以看到我们index.jsp中的内容，表示项目已经可以运行。

3. Spring与Activiti集成

 3.1 添加activiti的依赖包

3.2 配置spring-activiti.xml文件

在demo的src/main/resources目录下新建spring-activiti.xml文件，向其中加入以下内容。

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

3.3 修改web.xml文件

打开demo的web.xml文件，修改context-param为以下内容，对比上面的web.xml文件可知，此处只是添加了classpath:spring-activiti.xml这一项。

<context-param>

<param-name>contextConfigLocation</param-name> <param-value>classpath:spring.xml,classpath:spring-hibernate.xml,classpath:spring-activiti.xml</param-value>

</context-param>

此时activiti已经与springMVC+Spring+Hibernate集成在一起了，我们可以使用activiti提供的各种服务如repositoryService，runtimeService等。此处就不贴Junit的单元测试代码了，这里要写的话，又可以写成一个文档。

4.集成Activiti的在线流程设计器

 4.1 复制文件。

下载activiti-webapp-explorer2的源代码，将activiti-explorer工程中的diagram-viewer，editor-app和modeler.html文件复制到demo工程的src/main/webapp目录下，将activiti-explorer工程中WEB-INF/classes文件加下的stencilset.json，ui.properties，ui.properties.alfresco复制到demo工程的src/main/resources目录下。

复制完成之后的demo工程目录如下。

4.2 复制Controller文件。

打开activiti5.18.0的源码，将modules/目录中找到orgactiviti estdiagram和orgactiviti esteditor这两个包，将他们整个复制到demo工程的src/main/java目录下。复制完成后目录结构如图。

4.3修改spring-mvc.xml文件

修改spring-mvc.xml文件，在其中加入以下内容，使spring在扫描controller类的时候，也扫描这些包里面的类。



<context:component-scan base-package="org.activiti.rest.editor" />

<context:component-scan base-package="org.activiti.rest.diagram" />

4.4修改web.xml文件

打开demo工程的web.xml文件，向其中添加以下内容，让spring也管理起来带/service/的链接。

<servlet-mapping>

     <servlet-name>springmvc</servlet-name>

     <url-pattern>/service/*</url-pattern>

</servlet-mapping>

4.5 细节修改

打开editor-app/app-cfg.js, 将其中的“activiti-explorer”修改为“demo”。当然，具体项目中这里可能会经常变化，我们可以写一个js函数来自动获取工程的名字，这样以后将设计器集成到其他工程的时候，就不需要修改这里的内容了。做完这些操作之后，已经将activiti的页面流程设计器集成到了demo项目中了，下面我们编写一些代码做个测试

 5.测试Activiti页面流程设计器

在demo工程的srcmainjavaorgactiviti esteditor目录下新建一个java文件，命名为ModuleController,向其中加入以下内容。

import java.io.IOException;

import java.util.List;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.activiti.editor.constants.ModelDataJsonConstants;

import org.activiti.engine.ManagementService;

import org.activiti.engine.RepositoryService;

import org.activiti.engine.RuntimeService;

import org.activiti.engine.TaskService;

import org.activiti.engine.repository.Model;

import org.activiti.engine.repository.ProcessDefinition;

import org.activiti.engine.runtime.ProcessInstance;

import org.activiti.engine.task.Task;

import org.apache.commons.lang3.StringUtils;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestParam;

import org.springframework.web.servlet.ModelAndView;

import com.fasterxml.jackson.databind.ObjectMapper;

import com.fasterxml.jackson.databind.node.ObjectNode;

@Controller

@RequestMapping("/model")

public class ModuleController {

private Logger logger = LoggerFactory.getLogger(ModuleController.class);

@Autowired

private RepositoryService repositoryService;

@Autowired

private RuntimeService runtimeService;

@Autowired

private TaskService taskService;

@Autowired

private ManagementService managementService;

@RequestMapping(value = "create")

public void create(@RequestParam("name") String name, @RequestParam("key") String key,

@RequestParam("description") String description, HttpServletRequest request, HttpServletResponse response) {

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);

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"));

response.sendRedirect(request.getContextPath() + "/modeler.html?modelId=" + modelData.getId());

} catch (Exception e) {

logger.error("创建模型失败：", e);

}

}

}

然后将工程部署到tomcat下，启动tomcat。访问链接 http://localhost:8080/demo/model/create?name=test&key=test&description=testModel ,就可以看到系统自动创建了一个流程，浏览器自动跳转到设计器页面。我们就可以在设计器页面进行流程的设计了,你可以查看数据库，里面已经添加了相应的数据记录。
