activiti自己定义流程之Spring整合activiti-modeler实例（一）：环境搭建

项目中须要整合activiti-modeler自己定义流程，找了非常多资料后，最终成功的跳转到activiti-modeler流程设计界面。下面是记录：

一、整合基础：eclipse4.4.1、tomcat7、jdk1.7、mysql5.6.25、maven3.2.5、activiti5.16.3、spring4.0.9
二、步骤：
   1、下载activiti-5.16.3.zip: http://www.activiti.org/download.html
   2、解压zip文件，解压后的文件夹打开例如以下：
    
   

  3、打开上图中wars，可看到例如以下：
 
   

   4、把上图中的api、editor、explorer、libs拷贝到项目的webapp下，如图：
 

   5、进入第三步所看到的的WEB-INF的classes文件夹，可看到如图：
 

   6、把上图中的editor.html、stencilset.json、plugins.xml拷贝到项目的src/main/sources中，（spring.xml是自己建立的）如图：
 
  

 7、配置web.xml文件，整个文件内容例如以下：

 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">
     <filter>
         <description>字符集过滤器description>

         <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>
         <init-param>

             <param-value>UTF-8param-value>
         init-param>
     filter>
     <filter-mapping>
         <filter-name>encodingFilterfilter-name>
         <url-pattern>/*url-pattern>
     filter-mapping>


     <servlet>
     <servlet-name>RestletServletservlet-name>
     <servlet-class>org.restlet.ext.servlet.ServerServletservlet-class>
     <init-param>

         <welcome-file>default.htmwelcome-file>
         <welcome-file>default.jspwelcome-file>
     welcome-file-list>
 web-app>

8、使用maven导入须要的pring、activiti以及mysql的jar包。Pom.xml内容例如以下：

   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
   4.0.0
   activitiTest1
   activitiTest1
   war
   0.0.1-SNAPSHOT
   activitiTest1 Maven Webapp
   http://maven.apache.org


       junit
       junit
       3.8.1
       test


         org.springframework
         spring-beans

9、建立spring的配置文件spring.xml,例如以下：

 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:p="http://www.springframework.org/schema/p"
     xmlns:context="http://www.springframework.org/schema/context"
     xmlns:mvc="http://www.springframework.org/schema/mvc"
     xsi:schemaLocation="
         http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
         http://www.springframework.org/schema/context
         http://www.springframework.org/schema/context/spring-context-3.0.xsd
         http://www.springframework.org/schema/mvc
         http://www.springframework.org/schema/mvc/spring-mvc.xsd">


     <context:annotation-config />
     <mvc:annotation-driven />
     <context:component-scan base-package="controllers" />
     <bean id="dataSource" class="org.springframework.jdbc.datasource.SimpleDriverDataSource">

        <property name="driverClass" value="com.mysql.jdbc.Driver">property>
        <property name="url" value="jdbc:mysql://192.168.0.201:3306/testtu?useUnicode=true&characterEncoding=utf8" >property>
        <property name="username" value="root" >property>
        <property name="password" value="123456" >property>
     bean>

     <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource">property>
     bean>

     <bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
         <property name="dataSource" ref="dataSource" />
         <property name="databaseSchemaUpdate" value="true" />
         <property name="jobExecutorActivate" value="false"/>
         <property name="history" value="full"/>
         <property name="transactionManager" ref="transactionManager" />



     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="formService" factory-bean="processEngine" factory-method="getFormService" />


     <bean id="mappingJacksonHttpMessageConverter"
         class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
         <property name="supportedMediaTypes">
             <list>
                 <value>text/html;charset=UTF-8value>
             list>
         property>
     bean>



     <bean
         class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
         <property name="messageConverters">
             <list>
                 <ref bean="mappingJacksonHttpMessageConverter" />
             list>
         property>
     bean>

 beans>

10、建立controller类。用来控制页面跳转到activiti-modeler流程设计页面：

 package controllers;


 import java.util.HashMap;
 import java.util.Map;


 import javax.servlet.http.HttpServletRequest;
 import javax.servlet.http.HttpServletResponse;


 import org.activiti.editor.constants.ModelDataJsonConstants;
 import org.activiti.engine.RepositoryService;
 import org.activiti.engine.repository.Model;
 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.RequestMethod;
 import org.springframework.web.bind.annotation.RequestParam;
 import org.springframework.web.bind.annotation.ResponseBody;


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


 @Controller
 public class ActivitiController {
     @Autowired
     private RepositoryService repositoryService;


     /**
      * 查询生日列表
      *
      * @param req
      * @return
      */
     @RequestMapping(value = "/activiti.do", method = RequestMethod.GET, produces = "application/json;charset=utf-8")
     @ResponseBody
     public Object brithdayList(HttpServletRequest req) {
         Map map = new HashMap();
         map.put("name", "activiti");
         return map;
     }


     @RequestMapping(value = "/create.do", method = RequestMethod.GET, produces = "application/json;charset=utf-8")
     public void create(
             @RequestParam("name") String name,
             @RequestParam("key") String key,
             @RequestParam(value = "description", required = false) String description,
             HttpServletRequest request, HttpServletResponse response) {
         try {
             ObjectMapper objectMapper = new ObjectMapper();
             ObjectNode modelObjectNode = objectMapper.createObjectNode();
             modelObjectNode.put(ModelDataJsonConstants.MODEL_NAME, name);
             modelObjectNode.put(ModelDataJsonConstants.MODEL_REVISION, 1);
             modelObjectNode.put(ModelDataJsonConstants.MODEL_DESCRIPTION,
                     org.apache.commons.lang3.StringUtils
                             .defaultString(description));
             Model newModel = repositoryService.newModel();
             newModel.setMetaInfo(modelObjectNode.toString());
             newModel.setName(name);
             newModel.setKey(key);
             repositoryService.saveModel(newModel);
             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);
             repositoryService.addModelEditorSource(newModel.getId(), editorNode
                     .toString().getBytes("utf-8"));
             response.sendRedirect(request.getContextPath()
                     + "/service/editor?id=" + newModel.getId());
         } catch (Exception e) {
             e.getStackTrace();
         }
     }
 }

11、改动index.jsp为activiti.html:

 >
 <html>
 <head>
 <meta charset="utf-8">
 head>
 <body>
 <h2>Hello World!h2>
 <a href="./activiti.do">activitia>
   <form action="./create.do" method="get">
     <input type="text" id="name" name="name">input>
     <input type="text" id="key" name="key">input>
     <input type="text" id="description" name="description">input>
     <input type="submit" value="提交">
   form>
 body>
 html>

12、启动项目，使用http://localhost:8080/activitiTest1訪问项目，看到例如以下页面：

 
13、点击提交后，跳转到流程图设计界面：
