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

2024-11-26 04:58:02   203人阅读

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：
 技术分享

   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：
 技术分享
  

 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"?

    >

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

9、建立spring的配置文件spring.xml,例如以下：
[html] view plain copy
 技术分享技术分享
  1. <?

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

    >    

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

  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
 技术分享技术分享
  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;

  22.   
  23. import com.fasterxml.jackson.databind.ObjectMapper;

  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
 技术分享技术分享
  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：
