activiti自己定义流程之Spring整合activiti-modeler实例(七):任务列表展示
1.通过上一节的操作,能够知道流程启动以后会同一时候生成一个流程实例和用户任务。这个用户任务保存在act_ru_task和act_hi_task表中,从表明能够看出ru是runtime,hi是history。可是须要注意的是,和操作流程使用的service不同。操作正在发生任务不是使用runtimeService,而是专门的taskService。
2.后台业务代码,
(1)自己定义的任务实体类
(2)业务逻辑:查询任务使用taskService调用相关的方法来完毕,能够依据特定的条件,也能够不加条件查询全部。能够返回task为元素的list。也能够返回单独的task对象,可是须要注意的是,假设要返回单独的task对象。则必须确定返回值是唯一的对象,否则就会抛出异常。下边的样例中。我是依据当前登陆的username来查询出相应的全部task:

3.angular js前台代码(前台仅仅是做简单的展示,不多讲):
(1)app.js中配置路由:
- $stateProvider
- .state('taskList', {
- url: "/taskList",
- views: {
- 'view': {
- templateUrl: 'activi_views/taskList.html',
- controller: 'taskCtr'
- }
- }
- });
(2)逻辑相关代码:
- angular.module('activitiApp')
- .controller('taskCtr', ['$rootScope','$scope','$http','$location','$state', function($rootScope,$scope,$http,$location,$state){
- $scope.init=function(){
- $http.post("./findTask.do").success(function(result) {
- if(result.isLogin==="yes"){
- console.log(result.data);
- $rootScope.userName=result.userName;
- $scope.taskList=result.data;
- }else{
- $location.path("/login");
- }
- });
- }
- $scope.completeTaskTo=function(task){
- console.log(task);
- $rootScope.task=task;
- //$location.path("/completeTaskTo");
- $location.path("/completeTaskTo1");
- }
- }])
4.相应的填写相关信息的页面:
- <div id="logdiv1" ng-init="init();">
- <p style="font-size:22px;margin-top:10px">当前任务列表</p>
- <center>
- <table border="1px" style="width:87%;font-size:14px;text-align:center;margin-top:1px;margin-left:2px;position:relative;float:left;" cellSpacing="0px" cellPadding="0px">
- <tr style="background-color:#ccc">
- <td>类型</td>
- <td>ID</td>
- <td>NAME</td>
- <td>ProcessIntanceId</td>
- <td>ProcessDefId</td>
- <td>创建时间</td>
- <td>申请人</td>
- <td>受理人</td>
- <td>申请原因</td>
- <td>申请内容
