  • 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：

    [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

    1. <?

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

    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
     在CODE上查看代码片派生到我的代码片
    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;

    25.   
    26.   
    27. @Controller  
    28. public class ActivitiController {  
    29.     @Autowired  
    30.     private RepositoryService repositoryService;  
    31.   
    32.   
    33.     /**

    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,

    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
     在CODE上查看代码片派生到我的代码片
    1. <!DOCTYPE html>
