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，，，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 ，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"

<mvc:resources mapping="/static/css/**" location="/static/css/" />
<!-- 以下为SpringMVC配置 -->
<mvc:annotation-driven />
<bean id="defaultJsonView" class="org.springframework.web.servlet.view.json.MappingJackson2JsonView"/>
<!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass"

<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"

<property name="user" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<!-- 请求超时时间 -->
<property name="checkoutTimeout" value="30000" />
<!-- 每60秒检查所有连接池中的空闲连接。默认值: 0，不检查 -->
<property name="idleConnectionTestPeriod" value="30" />

</prop>
</props>
</property>
<!-- 扫描hibernate注解配置的entity -->
<property name="packagesToScan" value="com.fh.server.api.entity" />
</bean>
<!-- 配置事务管理器 -->
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<!-- 配置事务增强处理Bean，指定事务管理器 -->
<tx:advice id="transactionAdvice" transaction-manager="transactionManager">
<!-- 配置详细事务处理语义 -->
<tx:attributes>
<tx:method name="insert*" propagation="REQUIRED" />
<tx:method name="update*" propagation="REQUIRED" />
<tx:method name="delete*" propagation="REQUIRED" />
<tx:method name="get*" propagation="SUPPORTS" read-only="true" />
<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" />
<!-- 其他采用默认事务方式 -->
<tx:method name="*" />

<!-- Spring aop事务管理 -->
<aop:config>
<!-- 配置切入点 -->
<aop:pointcut id="transactionPointcut"
expression="execution(* com.fh.server.service..*Impl.*(..))" />
<!-- 指定在txAdvice切入点应用txAdvice事务增强处理 -->
<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 setting. -->
<defaultCache
maxElementsInMemory="1000"
eternal="false"
timeToIdleSeconds="120"
timeToLiveSeconds="120"
maxElementsOnDisk="1000000"
overflowToDisk="true"
memoryStoreEvictionPolicy="LRU">
</defaultCache>
<!-- Special objects setting. -->
<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">
<!-- 加载配置文件 -->
<context:property-placeholder location="classpath:config.properties"/>
<!-- 扫描service自动注入为bean -->
<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"

</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。

</dependency>
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"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
<property name="dataSource" ref="dataSource" />
<property name="transactionManager" ref="transactionManager" />
<property name="databaseSchemaUpdate" value="true" />
<property name="jobExecutorActivate" value="false" />
</bean>
<bean id="objectMapper" class="com.fasterxml.jackson.databind.ObjectMapper"/>
<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="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
</beans>
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org\activiti\rest\diagram和org\activiti\rest\editor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。
<!--加入Spring Activiti-Modeler的运行配置 -->
<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src\main\java\org\activiti\rest\editor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;
@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 ,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。
好长时间了，第一次写博客，CSDN的编辑器竟然不能直接从word里面复制粘贴，排版都乱了，见谅
