4.模型实体类：

  1. package model;
  2. import java.util.Date;
  3. public class ActivitiModel {
  4. private String id;
  5. private String name;
  6. private String key;
  7. private String description;
  8. private Date createTime;
  9. private Date lastUpdateTime;
  10. private int version;
  11. public String getId() {
  12. return id;
  13. }
  14. public void setId(String id) {
  15. this.id = id;
  16. }
  17. public Date getCreateTime() {
  18. return createTime;
  19. }
  20. public void setCreateTime(Date createTime) {
  21. this.createTime = createTime;
  22. }
  23. public Date getLastUpdateTime() {
  24. return lastUpdateTime;
  25. }
  26. public void setLastUpdateTime(Date lastUpdateTime) {
  27. this.lastUpdateTime = lastUpdateTime;
  28. }
  29. public int getVersion() {
  30. return version;
  31. }
  32. public void setVersion(int version) {
  33. this.version = version;
  34. }
  35. public String getName() {
  36. return name;
  37. }
  38. public void setName(String name) {
  39. this.name = name;
  40. }
  41. public String getKey() {
  42. return key;
  43. }
  44. public void setKey(String key) {
  45. this.key = key;
  46. }
  47. public String getDescription() {
  48. return description;
  49. }
  50. public void setDescription(String description) {
  51. this.description = description;
  52. }
  53. @Override
  54. public String toString() {
  55. return "ActivitiModel [id=" + id + ", name=" + name + ", key=" + key
  56. + ", description=" + description + ", createTime=" + createTime
  57. + ", lastUpdateTime=" + lastUpdateTime + ", version=" + version
  58. + "]";
  59. }
  60. }

5.后台业务代码，这里最后的操作是把跳转到acitiviti-modeler流程图设计界面的路径返回到了前端，然后让前端再跳转到流程图设计界面。

在我操作过程中，必须这样做才能实现设想的结果，因为我的前端使用的是angular js，页面上的路由跳转也都是由angular ui来控制，所以像第一篇spring整合activiti-modeler中那样从后台直接重定向的话就没有任何反应：

  1. /**
  2. * 创建模型
  3. *
  4. * @author：tuzongxun
  5. * @Title: create
  6. * @param @param activiti
  7. * @param @param request
  8. * @param @param response
  9. * @param @return
  10. * @return Object
  11. * @date Mar 17, 2016 12:30:29 PM
  12. * @throws
  13. */
  14. @RequestMapping(value = "/create.do", method = RequestMethod.POST, produces = "application/json;charset=utf-8")
  15. @ResponseBody
  16. public Object create(@RequestBody ActivitiModel activiti,
  17. HttpServletRequest request, HttpServletResponse response) {
  18. Map<String, String> map = new HashMap<String, String>();
  19. Boolean isLogin = this.isLogin(request);
  20. if (isLogin) {
  21. Model newModel = repositoryService.newModel();
  22. try {
  23. ObjectMapper objectMapper = new ObjectMapper();
  24. ObjectNode modelObjectNode = objectMapper.createObjectNode();
  25. modelObjectNode.put(ModelDataJsonConstants.MODEL_NAME,
  26. activiti.getName());
  27. modelObjectNode.put(ModelDataJsonConstants.MODEL_REVISION, 1);
  28. modelObjectNode.put(ModelDataJsonConstants.MODEL_DESCRIPTION,
  29. StringUtils.defaultString(activiti.getDescription()));
  30. newModel.setMetaInfo(modelObjectNode.toString());
  31. newModel.setName(activiti.getName());
  32. newModel.setKey(StringUtils.defaultString(activiti.getKey()));
  33. repositoryService.saveModel(newModel);
  34. ObjectNode editorNode = objectMapper.createObjectNode();
  35. editorNode.put("id", "canvas");
  36. editorNode.put("resourceId", "canvas");
  37. ObjectNode stencilSetNode = objectMapper.createObjectNode();
  38. stencilSetNode.put("namespace",
  39. "http://b3mn.org/stencilset/bpmn2.0#");
  40. editorNode.put("stencilset", stencilSetNode);
  41. repositoryService.addModelEditorSource(newModel.getId(),
  42. editorNode.toString().getBytes("utf-8"));
  43. } catch (Exception e) {
  44. e.getStackTrace();
  45. }
  46. // response.sendRedirect(request.getContextPath() +
  47. // "/service/editor?id="
  48. // + newModel.getId());
  49. map.put("isLogin", "yes");
  50. map.put("userName",
  51. (String) request.getSession().getAttribute("userName"));
  52. map.put("path", "/service/editor?id=");
  53. map.put("modelId", newModel.getId());
  54. } else {
  55. map.put("isLogin", "no");
  56. }
  57. return map;
  58. }

6.angular js前台代码，路由控制页面跳转：

（1）.app.js:

  1. $stateProvider
  2. .state('create', {
  3. url: "/create",
  4. views: {
  5. 'view': {
  6. templateUrl: 'activi_views/create.html',
  7. controller: 'createCtr'
  8. }
  9. }
  10. });

(2).createCtr.js，angular js中的控制器，和后台交互，按我们公司前端现在的标准做法，应该还要服务层service，但是我运用还不太熟练，就暂且都放在controller中了:

  1. angular.module('activitiApp')
  2. .controller('createCtr', ['$rootScope','$scope','$http','$location','$state', function($rootScope,$scope,$http,$location,$state){
  3. //创建模型
  4. $http.post("createFlush.do").success(function(result){
  5. if(result.isLogin==="yes"){
  6. $rootScope.userName=result.userName;
  7. }else{
  8. $location.path("/login");
  9. }
  10. });
  11. $scope.createTo=function(activiti){
  12. //向后台提交数据
  13. $http.post("./create.do",activiti,{headers:'Content-Type:application/json'}).success(function(createResult){
  14. console.log(createResult);
  15. $location.path("/modelList");
  16. window.open("http://localhost:8080/activitiTest1"+createResult.path+createResult.modelId);
  17. });
  18. }
  19. }])

7.如果模型创建成功，则可以看到数据库act_re_model中会出现一条数据，如下：

activiti自定义流程之Spring整合activiti-modeler5.16实例（二）：创建流程模型

同时在act_ge_bytearray表中会出现两条数据，如下图：

activiti自定义流程之Spring整合activiti-modeler5.16实例（二）：创建流程模型

并且可以看到，在model表中会有两个字段把bytearray表中两条数据的id保存起来。
