关于分页Pagination的使用

在这个例子当中，用的是ssm框架整合，并且用的是Pagination实现分页

先来看一下分页中用到的类的源码

Paginable.java

 1 package cn.itcast.common.page;
 2
 3 /**
 4  * 分页接口
 5  */
 6 public interface Paginable {
 7     /**

13
14     /**
15      * 总页数
16      *
17      * @return
18      */
19     public int getTotalPage();
20
21     /**
22      * 每页记录数
23      *
24      * @return
25      */
26     public int getPageSize();
27
28     /**

30      *
31      * @return
32      */
33     public int getPageNo();
34
35     /**
36      * 是否第一页
37      *
38      * @return
39      */
40     public boolean isFirstPage();
41
42     /**
43      * 是否最后一页
44      *
45      * @return
46      */
47     public boolean isLastPage();
48
49     /**
50      * 返回下页的页号
51      */
52     public int getNextPage();
53
54     /**

56      */
57     public int getPrePage();
