首先去activiti 下载Activiti,我用的是5.22.
下载完解压打开wars文件
解压activiti-explorer把里边的文件全部复制到项目的webapp下
然后打开activiti-5.22.0/lib,找到activiti-modeler-5.22.0-sources.jar
解压一下,把里边的java文件复制到SSM项目里
然后找到activiti-5.22.0\wars\activiti-explorer\WEB-INF\classes\stencilset.json 复制到resources下,设计器页面的中文包.
在applicationContext.xml中引入activiti配置文件
<!--引入Activiti-->
<import resource="classpath:/activiti/activiti.cfg.xml"/>
然后修改ModelEditorJsonRestResource,ModelSaveRestResource,StencilsetRestResource在三个类的方法上都添加service前缀,如:
package com.ys.activiti;
import org.activiti.engine.ActivitiException;
import org.apache.commons.io.IOUtils;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import java.io.InputStream;
@RestController
public class StencilsetRestResource
{
@RequestMapping(value={"/service/editor/stencilset"}, method={org.springframework.web.bind.annotation.RequestMethod.GET}, produces={"application/json;charset=utf-8"})
@ResponseBody
public String getStencilset()
{
System.out.println("StencilsetRestResource.getStencilset-----------");
InputStream stencilsetStream = getClass().getClassLoader().getResourceAsStream("stencilset.json");
try {
return IOUtils.toString(stencilsetStream, "utf-8");
} catch (Exception e) {
throw new ActivitiException("Error while loading stencil set", e);
}
}
}
然后修改editor-app里的app-cfg.js,在service前边加上项目路径,如:

var ACTIVITI = ACTIVITI || {};
ACTIVITI.CONFIG = {
'contextRoot' : '/myProject/service',
};
新建controller文件,创建activiti模型
package com.ys.controller;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.node.ObjectNode;
import org.activiti.bpmn.converter.BpmnXMLConverter;
import org.activiti.bpmn.model.BpmnModel;
import org.activiti.editor.constants.ModelDataJsonConstants;
import org.activiti.editor.language.json.converter.BpmnJsonConverter;
import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngines;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.repository.Deployment;
import org.activiti.engine.repository.Model;
import org.activiti.engine.runtime.ProcessInstance;
import org.activiti.engine.task.Task;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.List;
/**
* @ClassName ActivitiController
* @description:
* @time 2018/9/2517:07
**/
@RestController
@RequestMapping("/act")
public class ActivitiController {
/**
* 创建模型
*/
@RequestMapping("create")
public void create(HttpServletRequest request, HttpServletResponse response) {
try {
ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
RepositoryService repositoryService = processEngine.getRepositoryService();
ObjectMapper objectMapper = new ObjectMapper();
ObjectNode editorNode = objectMapper.createObjectNode();
editorNode.put("id", "ceshi");
editorNode.put("resourceId", "ceshi");
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, "测试");
modelObjectNode.put(ModelDataJsonConstants.MODEL_REVISION, 1);
String description = "测试---";
modelObjectNode.put(ModelDataJsonConstants.MODEL_DESCRIPTION, description);
modelData.setMetaInfo(modelObjectNode.toString());
modelData.setName("lutiannan");
modelData.setKey("ceshi");
//保存模型
repositoryService.saveModel(modelData);
repositoryService.addModelEditorSource(modelData.getId(), editorNode.toString().getBytes("utf-8"));
response.sendRedirect(request.getContextPath() + "/modeler.html?modelId=" + modelData.getId());
} catch (Exception e) {
System.out.println("创建模型失败：");
}
}
}
然后在页面请求act/create方法进入activiti-modeler页面则成功
完成.
