1.任务安排，画表格展示
| 计划时间 | 计划任务 | 计划是否完成 |
| 3.22-3.29 | 管理员的增删改查 | 是 |
| 3.29-4.5 | 编写活动模块 | 是 |
| 4.16-4.22 | 完善活动的增删改查 | 是 |
| 4.23-4.30 | 分类管理员与用户界面，交接前端 |
2.本周完成内容
完善了活动的增删改查
3.本周实现代码
主要是修改了event的servlet层代码，上周的代码不能正确调用，这周进行了完善

113 }
114 }else
115 {
116
117 }
118 }
119
120 }
4.本周代码实现截图
活动的增加和查询（面向管理员） 出现了点中文乱码问题，应该不难解决
活动的修改
活动的删除
5.本周碰到问题及解决方法
主要是没有正确的调用给之前给EventID命名的名称，然后就是时间类型不好设置和调用，正在考虑怎么实现最好
6.本周小结
活动的增删改查都写好了，但主要是面向管理员的，面向用户的准备下一周做出来，然后前端页面尽量花时间去做出来，
