springmvc+spring+mybatis分頁查詢實例版本3,添加條件檢索

在第二個版本上添加了姓名模糊查詢,年齡區間查詢;自以為easy,結果發現mybatis的各種參數寫法基本搞混或是忘了,zuo啊,直接上代碼,然后趕緊把mybatis整理一遍再研究自己的項目,應該還會有個版本4,基本就可以搬到實際項目上使用了,話說自己的項目要抓緊了,最近做的有點慢,也是沒辦法,工作偏忙,空閑時想看的東西太多,還是要科學計划一下,

效果如下:

還原再來

其實應該再加個清空條件后重新檢索全部的功能,不過想想算了,沒必要,就一個顯示全部,復制一個search去掉js的驗證就可以了,實際用起來還要再細致化去使用,先這樣

 又看了這個http://liuzidong.iteye.com/blog/1055491神的代碼,嗯感覺可以噠,時間有限,等到實際項目再采用練手吧
