2.基础配置:web.xml,这个也主要是spring相关的东西,不多说了:
- <?xml version="1.0" encoding="UTF-8"?>

3.基础配置spring.xml:

4.模型实体类:
- package model;
- import java.util.Date;
- public class ActivitiModel {
- private String id;
- private String name;
- private String key;
- private String description;
- private Date createTime;
- private Date lastUpdateTime;
- private int version;
- public String getId() {
- return id;
- }
- public void setId(String id) {
- this.id = id;
- }
- public Date getCreateTime() {
- return createTime;
- }
- public void setCreateTime(Date createTime) {
- this.createTime = createTime;
- }
- public Date getLastUpdateTime() {
- return lastUpdateTime;
- }
- public void setLastUpdateTime(Date lastUpdateTime) {
- this.lastUpdateTime = lastUpdateTime;
- }
- public int getVersion() {
- return version;
- }
- public void setVersion(int version) {
- this.version = version;
- }
- public String getName() {
- return name;
- }
- public void setName(String name) {
- this.name = name;
- }
- public String getKey() {
- return key;
- }
- public void setKey(String key) {
- this.key = key;
- }
- public String getDescription() {
- return description;
- }
- public void setDescription(String description) {
- this.description = description;
- }
- @Override
- public String toString() {
- return "ActivitiModel [id=" + id + ", name=" + name + ", key=" + key
- + ", description=" + description + ", createTime=" + createTime
- + ", lastUpdateTime=" + lastUpdateTime + ", version=" + version
- + "]";
- }
- }
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:
- /**
- * 创建模型
- *
- * @author:tuzongxun
- * @Title: create
- * @param @param activiti
- * @param @param request
- * @param @param response
- * @param @return
- * @return Object
- * @date Mar 17, 2016 12:30:29 PM
- * @throws
- */
- @RequestMapping(value = "/create.do", method = RequestMethod.POST, produces = "application/json;charset=utf-8")
- @ResponseBody
- public Object create(@RequestBody ActivitiModel activiti,
- HttpServletRequest request, HttpServletResponse response) {
- Map<String, String> map = new HashMap<String, String>();
- Boolean isLogin = this.isLogin(request);
- if (isLogin) {
- Model newModel = repositoryService.newModel();
- try {
- ObjectMapper objectMapper = new ObjectMapper();
- ObjectNode modelObjectNode = objectMapper.createObjectNode();
- modelObjectNode.put(ModelDataJsonConstants.MODEL_NAME,
- activiti.getName());
- modelObjectNode.put(ModelDataJsonConstants.MODEL_REVISION, 1);
- modelObjectNode.put(ModelDataJsonConstants.MODEL_DESCRIPTION,
- StringUtils.defaultString(activiti.getDescription()));
- newModel.setMetaInfo(modelObjectNode.toString());
- newModel.setName(activiti.getName());
- newModel.setKey(StringUtils.defaultString(activiti.getKey()));
- repositoryService.saveModel(newModel);
- ObjectNode editorNode = objectMapper.createObjectNode();
- editorNode.put("id", "canvas");
- editorNode.put("resourceId", "canvas");
- ObjectNode stencilSetNode = objectMapper.createObjectNode();
- stencilSetNode.put("namespace",
- "http://b3mn.org/stencilset/bpmn2.0#");
- editorNode.put("stencilset", stencilSetNode);
- repositoryService.addModelEditorSource(newModel.getId(),
- editorNode.toString().getBytes("utf-8"));
- } catch (Exception e) {
- e.getStackTrace();
- }
- // response.sendRedirect(request.getContextPath() +
- // "/service/editor?id="
- // + newModel.getId());
- map.put("isLogin", "yes");
- map.put("userName",
- (String) request.getSession().getAttribute("userName"));
- map.put("path", "/service/editor?id=");
- map.put("modelId", newModel.getId());
- } else {
- map.put("isLogin", "no");
- }
- return map;
- }
6.angular js前台代码,路由控制页面跳转:
(1).app.js:
- $stateProvider
- .state('create', {
- url: "/create",
- views: {
- 'view': {
- templateUrl: 'activi_views/create.html',
- controller: 'createCtr'
- }
- }
- });
(2).createCtr.js,angular js中的控制器,和后台交互,按我们公司前端现在的标准做法,应该还要服务层service,但是我运用还不太熟练,就暂且都放在controller中了:
- angular.module('activitiApp')
- .controller('createCtr', ['$rootScope','$scope','$http','$location','$state', function($rootScope,$scope,$http,$location,$state){
- //创建模型
- $http.post("createFlush.do").success(function(result){
- if(result.isLogin==="yes"){
- $rootScope.userName=result.userName;
- }else{
- $location.path("/login");
- }
- });
- $scope.createTo=function(activiti){
- //向后台提交数据
- $http.post("./create.do",activiti,{headers:'Content-Type:application/json'}).success(function(createResult){
- console.log(createResult);
- $location.path("/modelList");
- window.open("http://localhost:8080/activitiTest1"+createResult.path+createResult.modelId);
- });
- }
- }])
(3).index.html:

(4).create.html:

- <input style="font-size:28px;cursor:pointer" type="button" value="返回">
- </div>
- </center>
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:
同时在act_ge_bytearray表中会出现两条数据,如下图:
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。
