Asp.Net MVC 3 + ExtJs 4.01做一个Quartz.Net管理平台

在原来的公司曾经用asp.net + extjs 2做过一个Quartz.Net简单管理平台（后来申请了著作权，尽然也可以），随着Asp.Net MVC 3和ExtJs 4的发布，突然有了重新用Asp.Net MVC 3 + ExtJs 4重新做一下的冲动（冲动是魔鬼呀。。。）。本次只实现了显示触发器Trigger的信息。

效果图：

 

1.定义TriggerInfo，这里为了方便起见只列出了TriggerInfo的定义

 1     using System;
 2     using System.Runtime.Serialization;
 3 
 4     [DataContract]
 5     public class TriggerInfo
 6     {
 7         [DataMember]
 8         public string CalendarName { get; set; }
 9 
10         [DataMember]
11         public string Description { get; set; }
12 
13         [DataMember]
14         public DateTime? EndTimeUtc { get; set; }
15 
16         [DataMember]
17         public DateTime? FinalFireTimeUtc { get; set; }
18 
19         [DataMember]
20         public string FireInstanceId { set; get; }
21 
22         [DataMember]
23         public string FullJobName { get; set; }
24 
25         [DataMember]
26         public string FullName { get; set; }
27 
28         [DataMember]
29         public string Group { get; set; }
30 
31         [DataMember]
32         public bool HasAdditionalProperties { get; set; }
33 
34         [DataMember]
35         public bool HasMillisecondPrecision { get; set; }
36 
37         [DataMember]
38         public string JobGroup { get; set; }
39 
40         [DataMember]
41         public string JobName { get; set; }
42 
43         [DataMember]
44         public string Key { get; set; }
45 
46         [DataMember]
47         public bool MayFireAgain { get; set; }
48 
49         [DataMember]
50         public int MisfireInstruction { get; set; }
51 
52         [DataMember]
53         public string Name { get; set; }
54 
55         [DataMember]
56         public DateTime? NextFireTimeUtc { get; set; }
57 
58         [DataMember]
59         public DateTime? PreviousFireTimeUtc { get; set; }
60 
61         [DataMember]
62         public int Priority { get; set; }
63 
64         [DataMember]
65         public DateTime StartTimeUtc { get; set; }
66 
67         [DataMember]
68         public string[] TriggerListenerNames { get; set; }
69 
70         [DataMember]
71         public TriggerType TriggerType { get; set; }
72 
73         [DataMember]
74         public TriggerStateInfo TriggerState { get; set; }
75 
76         [DataMember]
77         public bool Volatile { get; set; }
78 
79         [DataMember]
80         public int RepeatCount { get; set; }
81 
82         [DataMember]
83         public TimeSpan RepeatInterval { get; set; }
84 
85         [DataMember]
86         public int TimesTriggered { get; set; }
87 
88         [DataMember]
89         public int RepeatIndefinitely { get; set; }
90 
91         [DataMember]
92         public string CronExpressionString { get; set; }
93 
94         [DataMember]
95         public TimeZoneInfo TimeZone { get; set; }
96     }

2.定义服务契约IScheduleService

  1     using System;
  2     using System.ServiceModel;
  3 
  4     using DataContract;
  5 
  6     [ServiceContract]
  7     public interface IScheduleService
  8     {
  9         [OperationContract]
 10         void AddJob(JobInfo jobInfo, bool replace);
 11 
 12         [OperationContract]
 13         bool DeleteJob(string jobName, string groupName);
 14 
 15         [OperationContract]
 16         string[] GetJobGroupNames();
 17 
 18         [OperationContract]
 19         JobInfo GetJobDetail(string jobName, string groupName);
 20 
 21         [OperationContract]
 22         string[] GetJobNames(string groupName);
 23 
 24         [OperationContract]
 25         TriggerInfo GetTrigger(string triggerName, string groupName);
 26 
 27         [OperationContract]
 28         string[] GetTriggerGroupNames();
 29 
 30         [OperationContract]
 31         string[] GetTriggerNames(string groupName);
 32 
 33         [OperationContract]
 34         TriggerStateInfo GetTriggerState(string triggerName, string triggerGroup);
 35 
 36         [OperationContract]
 37         bool IsJobGroupPaused(string groupName);
 38 
 39         [OperationContract]
 40         bool IsTriggerGroupPaused(string groupName);
 41 
 42         [OperationContract]
 43         void PauseAll();
 44 
 45         [OperationContract]
 46         void PauseJob(string jobName, string groupName);
 47 
 48         [OperationContract]
 49         void PauseJobGroup(string groupName);
 50 
 51         [OperationContract]
 52         void PauseTrigger(string triggerName, string triggerGroup);
 53 
 54         [OperationContract]
 55         void PauseTriggerGroup(string triggerGroup);
 56 
 57         [OperationContract]
 58         DateTime? RescheduleJob(string triggerName, string triggerGroup, TriggerInfo newTrigger);
 59 
 60         [OperationContract]
 61         void ResumeAll();
 62 
 63         [OperationContract]
 64         void ResumeJob(string jobName, string groupName);
 65 
 66         [OperationContract]
 67         void ResumeJobGroup(string groupName);
 68 
 69         [OperationContract]
 70         void ResumeTrigger(string triggerName, string groupName);
 71 
 72         [OperationContract]
 73         void ResumeTriggerGroup(string groupName);
 74 
 75         [OperationContract]
 76         DateTime ScheduleJob(TriggerInfo trigger);
 77 
 78         [OperationContract]
 79         DateTime ScheduleJobByTrigger(JobInfo jobInfo, TriggerInfo trigger);
 80 
 81         [OperationContract]
 82         void Shutdown(bool waitForJobsToComplete);
 83 
 84         [OperationContract]
 85         void Standby();
 86 
 87         [OperationContract]
 88         void Start();
 89 
 90         [OperationContract]
 91         void StartDelayed(TimeSpan delay);
 92 
 93         [OperationContract]
 94         void TriggerJob(string jobName, string groupName);
 95 
 96         [OperationContract]
 97         void TriggerJobWithVolatileTrigger(string jobName, string groupName);
 98 
 99         [OperationContract]
100         void UnscheduleJob(string triggerName, string groupName);
101     }

3.实现服务契约IScheduleService的ScheduleService ，由于服务提交代码，只能描述一下了，这个类就是把Quartz.Net的Schedule封装了一下。

4.定义SchduleController，来输出Job和Trigger的信息

 1     using System.Collections.Generic;
 2     using System.Web.Mvc;
 3 
 4     using Vancl.Schedule.DataContract;
 5     using Vancl.Schedule.ServiceContract;
 6     using Vancl.Schedule.ServiceImpl;
 7 
 8     public class ScheduleController : Controller
 9     {
10         private readonly IScheduleService scheduleService = ScheduleService.Instance;
11 
12         /// <summary>
13         /// 获取所有任务
14         /// </summary>
15         /// <returns></returns>
16         public ActionResult GetJobs()
17         {
18             IList<JobInfo> jobInfoes = new List<JobInfo>();
19 
20             string[] groupNames = scheduleService.GetJobGroupNames();
21 
22             if (groupNames != null)
23             {
24                 foreach (string groupName in groupNames)
25                 {
26                     string[] jobNames = scheduleService.GetJobNames(groupName);
27 
28                     if (jobNames != null)
29                     {
30                         foreach (string jobName in jobNames)
31                         {
32                             jobInfoes.Add(scheduleService.GetJobDetail(jobName, groupName));
33                         }
34                     }
35                 }
36             }
37 
38             return new JsonResult() { Data = jobInfoes, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
39         }
40 
41         /// <summary>
42         /// 获取所有触发器
43         /// </summary>
44         /// <returns></returns>
45         public ActionResult GetTriggers()
46         {
47             IList<TriggerInfo> triggerInfoes = new List<TriggerInfo>();
48 
49             string[] groupNames = scheduleService.GetTriggerGroupNames();
50 
51             if (groupNames != null)
52             {
53                 foreach (string groupName in groupNames)
54                 {
55                     string[] triggerNames = scheduleService.GetTriggerNames(groupName);
56 
57                     if (triggerNames != null)
58                     {
59                         foreach (string triggerName in triggerNames)
60                         {
61                             TriggerInfo triggerInfo = scheduleService.GetTrigger(triggerName, groupName);
62                             triggerInfo.TriggerState = scheduleService.GetTriggerState(triggerName, groupName);
63                             triggerInfoes.Add(triggerInfo);
64                         }
65                     }
66                 }
67             }
68 
69             return new JsonResult() { Data = triggerInfoes, JsonRequestBehavior = JsonRequestBehavior.AllowGet };
70         }
71     }

5.定义TriggerInfo，扩展于Ext.data.Model

 Ext.define("Vancl.Cxcp.TriggerInfo", {
2     extend: 'Ext.data.Model',
3     fields: ['Name', 'Group', 'JobName', 'JobGroup', 'TriggerType', 'StartTimeUtc', 'PreviousFireTimeUtc', 'NextFireTimeUtc', 'MisfireInstruction', 'TriggerState']
4 });

 6.出于方便，我直接利用了Ext的desktop，下面是用于显示所有Trigger信息的Grid

  1 Ext.define('MyDesktop.GridWindow', {
  2     extend: 'Ext.ux.desktop.Module',
  3 
  4     requires: [
  5         'Ext.data.*',
  6         'Ext.util.Format',
  7         'Ext.grid.Panel',
  8         'Ext.grid.RowNumberer'
  9     ],
 10 
 11     id: 'grid-win',
 12 
 13     init: function () {
 14         this.launcher = {
 15             text: 'Grid Window',
 16             iconCls: 'icon-grid',
 17             handler: this.createWindow,
 18             scope: this
 19         };
 20     },
 21 
 22     createWindow: function () {
 23         var desktop = this.app.getDesktop();
 24         var win = desktop.getWindow('grid-win');
 25         var store = new Ext.data.Store({
 26             model: 'Vancl.Cxcp.TriggerInfo',
 27             proxy: {
 28                 type: 'ajax',
 29                 url: 'schedule/gettriggers',
 30                 reader: {
 31                     type: 'json',
 32                     root: ''
 33                 }
 34             }
 35         });
 36         if (!win) {
 37             win = desktop.createWindow({
 38                 id: 'grid-win',
 39                 title: '触发器信息',
 40                  740,
 41                 height: 480,
 42                 iconCls: 'icon-grid',
 43                 animCollapse: false,
 44                 constrainHeader: true,
 45                 layout: 'fit',
 46                 items: [
 47                     {
 48                         border: false,
 49                         xtype: 'grid',
 50                         store: store,
 51                         columns: [{
 52                             text: 'Name',
 53                             dataIndex: 'Name'
 54                         }, {
 55                             text: 'Group',
 56                             dataIndex: 'Group'
 57                         }, {
 58                             text: 'JobName',
 59                             dataIndex: 'JobName'
 60                         }, {
 61                             text: 'JobGroup',
 62                             dataIndex: 'JobGroup'
 63                         }, {
 64                             text: 'TriggerType',
 65                             dataIndex: 'TriggerType'
 66                         }, {
 67                             text: 'StartTimeUtc',
 68                             dataIndex: 'StartTimeUtc'
 69                         }, {
 70                             text: 'PreviousFireTimeUtc',
 71                             dataIndex: 'PreviousFireTimeUtc'
 72                         }, {
 73                             text: 'NextFireTimeUtc',
 74                             dataIndex: 'NextFireTimeUtc'
 75                         }, {
 76                             text: 'MisfireInstruction',
 77                             dataIndex: 'MisfireInstruction'
 78                         }, {
 79                             text: 'TriggerState',
 80                             dataIndex: 'TriggerState'
 81                         }]
 82                     }
 83                 ],
 84                 tbar: [{
 85                     text: 'Add',
 86                     tooltip: 'Add a new trigger',
 87                     iconCls: 'add'
 88                 }, '-', {
 89                     text: 'Remove Trigger',
 90                     tooltip: 'Remove the selected trigger',
 91                     iconCls: 'remove'
 92                 }]
 93             });
 94         }
 95         win.show();
 96         store.load();
 97 
 98         return win;
 99     }
100 });

 从以上示例可以看出，ExtJs 4相对于ExtJs 2/3已经有了很大的变化。比如 data model，对于对象的定义更加简单明了。
