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

Posted 2020-10-02 jhcelue

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：

[html] view plain copy

 

1. <?

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

   >  

2. <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
3.     xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"  
4.     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"  
5.     id="WebApp_ID" version="2.5">      
6.     <filter>  
7.         <description>字符集过滤器</description>  
8.         <filter-name>encodingFilter</filter-name>  
9.         <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>  
10.         <init-param>  
11.             <description>字符集编码</description>  
12.             <param-name>encoding</param-name>  
13.             <param-value>UTF-8</param-value>  
14.         </init-param>  
15.     </filter>  
16.     <filter-mapping>  
17.         <filter-name>encodingFilter</filter-name>  
18.         <url-pattern>/*</url-pattern>  
19.     </filter-mapping>  
20.   
21.   
22.     <servlet>  
23.     <servlet-name>RestletServlet</servlet-name>  
24.     <servlet-class>org.restlet.ext.servlet.ServerServlet</servlet-class>  
25.     <init-param>  
26.       <param-name>org.restlet.application</param-name>  
27.       <param-value>org.activiti.rest.editor.application.ModelerRestApplication</param-value>  
28.     </init-param>  
29.   </servlet>  
30.   <servlet-mapping>  
31.     <servlet-name>RestletServlet</servlet-name>  
32.     <url-pattern>/service/*</url-pattern>  
33.   </servlet-mapping>  
34.       
35.       
36.     <servlet>    
37.         <servlet-name>springMVC</servlet-name>    
38.         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    
39.         <init-param>    
40.             <param-name>contextConfigLocation</param-name>    
41.             <param-value>classpath:spring.xml</param-value>    
42.         </init-param>      
43.     </servlet>    
44.     <servlet-mapping>    
45.         <servlet-name>springMVC</servlet-name>    
46.         <url-pattern>*.do</url-pattern>    
47.     </servlet-mapping>  
48.     <welcome-file-list>  
49.         <welcome-file>activiti.html</welcome-file>  
50.         <welcome-file>activiti.htm</welcome-file>  
51.         <welcome-file>activiti.jsp</welcome-file>  
52.         <welcome-file>default.html</welcome-file>  
53.         <welcome-file>default.htm</welcome-file>  
54.         <welcome-file>default.jsp</welcome-file>  
55.     </welcome-file-list>    
56. </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：

[plain] view plain copy

 

1. <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
2.   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">  
3.   <modelVersion>4.0.0</modelVersion>

125.   <build>  
126.     <finalName>activitiTest1</finalName>  
127.   </build>  
128. </project>  

9、建立spring的配置文件spring.xml,例如以下：

[html] view plain copy

 

1. <?

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

   >    

2. <beans xmlns="http://www.springframework.org/schema/beans"    
3.     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"    
4.     xmlns:context="http://www.springframework.org/schema/context"    
5.     xmlns:mvc="http://www.springframework.org/schema/mvc"      
6.     xsi:schemaLocation="    
7.         http://www.springframework.org/schema/beans     
8.         http://www.springframework.org/schema/beans/spring-beans-3.0.xsd    
9.         http://www.springframework.org/schema/context     
10.         http://www.springframework.org/schema/context/spring-context-3.0.xsd  
11.         http://www.springframework.org/schema/mvc   
12.         http://www.springframework.org/schema/mvc/spring-mvc.xsd">    
13.   
14.   
15.     <context:annotation-config />    
16.     <mvc:annotation-driven />  
17.     <context:component-scan base-package="controllers" />    
18.     <bean id="dataSource" class="org.springframework.jdbc.datasource.SimpleDriverDataSource">  
19.          
20.        <property name="driverClass" value="com.mysql.jdbc.Driver"></property>  
21.        <property name="url" value="jdbc:mysql://192.168.0.201:3306/testtu?

    useUnicode=true&characterEncoding=utf8" ></property>  

22.        <property name="username" value="root" ></property>   
23.        <property name="password" value="123456" ></property>   
24.     </bean>  
25.       
26.     <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">  
27.        <property name="dataSource" ref="dataSource"></property>  
28.     </bean>  
29.       
30.     <bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">  
31.         <property name="dataSource" ref="dataSource" />  
32.         <property name="databaseSchemaUpdate" value="true" />  
33.         <property name="jobExecutorActivate" value="false"/>  
34.         <property name="history" value="full"/>  
35.         <property name="transactionManager" ref="transactionManager" />  
36.         <!-- 配置事务管理器。统一事务 -->  
37.           
38.         <!-- 设置建表策略，假设没有表，自己主动创建表 -->  
39.     </bean>  
40.     <!-- 创建流程引擎对象 -->  
41.     <bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">  
42.         <property name="processEngineConfiguration" ref="processEngineConfiguration" />  
43.     </bean>  
44.   
45.   
46.     <!-- 由流程引擎对象。提供的方法，创建项目中使用的Activiti工作流的Service -->  
47.     <bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService" />  
48.     <bean id="runtimeService" factory-bean="processEngine" factory-method="getRuntimeService" />  
49.     <bean id="taskService" factory-bean="processEngine" factory-method="getTaskService" />  
50.     <bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService" />  
51.     <bean id="formService" factory-bean="processEngine" factory-method="getFormService" />  
52.        
53.     <!-- 避免IE运行AJAX时,返回JSON出现下载文件 -->  
54.     <bean id="mappingJacksonHttpMessageConverter"  
55.         class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">  
56.         <property name="supportedMediaTypes">  
57.             <list>  
58.                 <value>text/html;charset=UTF-8</value>  
59.             </list>  
60.         </property>  
61.     </bean>  
62.   
63.   
64.     <!-- 启动Spring MVC的注解功能，完毕请求和注解POJO的映射 -->  
65.     <bean  
66.         class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">  
67.         <property name="messageConverters">  
68.             <list>  
69.                 <ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 -->  
70.             </list>  
71.         </property>  
72.     </bean>  
73.       
74. </beans>    

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

[java] view plain copy

 

1. package controllers;  
2.   
3.   
4. import java.util.HashMap;  
5. import java.util.Map;  
6.   
7.   
8. import javax.servlet.http.HttpServletRequest;  
9. import javax.servlet.http.HttpServletResponse;  
10.   
11.   
12. import org.activiti.editor.constants.ModelDataJsonConstants;  
13. import org.activiti.engine.RepositoryService;  
14. import org.activiti.engine.repository.Model;  
15. import org.springframework.beans.factory.annotation.Autowired;  
16. import org.springframework.stereotype.Controller;  
17. import org.springframework.web.bind.annotation.RequestMapping;  
18. import org.springframework.web.bind.annotation.RequestMethod;  
19. import org.springframework.web.bind.annotation.RequestParam;  
20. import org.springframework.web.bind.annotation.ResponseBody;  
21.   
22.   
23. import com.fasterxml.jackson.databind.ObjectMapper;  
24. import com.fasterxml.jackson.databind.node.ObjectNode;  
25.   
26.   
27. @Controller  
28. public class ActivitiController {  
29.     @Autowired  
30.     private RepositoryService repositoryService;  
31.   
32.   
33.     /** 
34.      * 查询生日列表 
35.      *  
36.      * @param req 
37.      * @return 
38.      */  
39.     @RequestMapping(value = "/activiti.do", method = RequestMethod.GET, produces = "application/json;charset=utf-8")  
40.     @ResponseBody  
41.     public Object brithdayList(HttpServletRequest req) {  
42.         Map<String, Object> map = new HashMap<String, Object>();  
43.         map.put("name", "activiti");  
44.         return map;  
45.     }  
46.   
47.   
48.     @RequestMapping(value = "/create.do", method = RequestMethod.GET, produces = "application/json;charset=utf-8")  
49.     public void create(  
50.             @RequestParam("name") String name,  
51.             @RequestParam("key") String key,  
52.             @RequestParam(value = "description", required = false) String description,  
53.             HttpServletRequest request, HttpServletResponse response) {  
54.         try {  
55.             ObjectMapper objectMapper = new ObjectMapper();  
56.             ObjectNode modelObjectNode = objectMapper.createObjectNode();  
57.             modelObjectNode.put(ModelDataJsonConstants.MODEL_NAME, name);  
58.             modelObjectNode.put(ModelDataJsonConstants.MODEL_REVISION, 1);  
59.             modelObjectNode.put(ModelDataJsonConstants.MODEL_DESCRIPTION,  
60.                     org.apache.commons.lang3.StringUtils  
61.                             .defaultString(description));  
62.             Model newModel = repositoryService.newModel();  
63.             newModel.setMetaInfo(modelObjectNode.toString());  
64.             newModel.setName(name);  
65.             newModel.setKey(key);  
66.             repositoryService.saveModel(newModel);  
67.             ObjectNode editorNode = objectMapper.createObjectNode();  
68.             editorNode.put("id", "canvas");  
69.             editorNode.put("resourceId", "canvas");  
70.             ObjectNode stencilSetNode = objectMapper.createObjectNode();  
71.             stencilSetNode.put("namespace",  
72.                     "http://b3mn.org/stencilset/bpmn2.0#");  
73.             editorNode.put("stencilset", stencilSetNode);  
74.             repositoryService.addModelEditorSource(newModel.getId(), editorNode  
75.                     .toString().getBytes("utf-8"));  
76.             response.sendRedirect(request.getContextPath()  
77.                     + "/service/editor?id=" + newModel.getId());  
78.         } catch (Exception e) {  
79.             e.getStackTrace();  
80.         }  
81.     }  
82. }  

11、改动index.jsp为activiti.html:

[html] view plain copy

 

1. <!DOCTYPE html>  
2. <html>  
3. <head>  
4. <meta charset="utf-8">  
5. </head>  
6. <body>  
7. <h2>Hello World!</h2>  
8. <a href="./activiti.do">activiti</a>  
9.   <form action="./create.do" method="get">  
10.     <input type="text" id="name" name="name"></input>  
11.     <input type="text" id="key" name="key"></input>  
12.     <input type="text" id="description" name="description"></input>  
13.     <input type="submit" value="提交">  
14.   </form>  
15. </body>  
16. </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：
