1.使用maven解决依赖
<dependency>
<groupId>com.github.pagehelper</groupId>
<artifactId>pagehelper</artifactId>
<version>3.4.2</version>
</dependency>
2.在Controller调用Service的时候,调用PageHelper
@RequestMapping("/sysadmin/dept/list")
public String toDeptList(Model model,@RequestParam(required = false,defaultValue = "1",value = "pn")Integer pn ) {
PageHelper.startPage(pn, 8);
List<Dept> deptList = deptService.findAll();
PageInfo<Dept> p = new PageInfo<>(deptList);
model.addAttribute("deptList", deptList);
model.addAttribute("page", p);
return "sysadmin/dept/jDeptList";
}
PageHelper.startPage(pn, 8); //参数分别是设置当前的页数和每页的数量
PageInfo<Dept> p = new PageInfo<>(deptList); //将得到查询结果集进行封装
3.在jsp页面进行简单的分页
<a href="/sysadmin/dept/list?pn=${page.firstPage}">首页</a>
<c:if test="${page.hasPreviousPage}"><a href="/sysadmin/dept/list?pn=${page.prePage}">上一页</a></c:if>
<c:if test="${!page.hasPreviousPage}">上一页</c:if>
<c:if test="${page.hasNextPage}"><a href="/sysadmin/dept/list?pn=${page.nextPage}">下一页</a></c:if>
<c:if test="${! page.hasNextPage}">下一页</c:if>
<a href="/sysadmin/dept/list?pn=${page.lastPage}">最后页</a>
<p>一共${page.pages}页 --当前页是${page.pageNum } -- 共有${page.total }条数据</p>
简单的进行了调用,实现了基本的功能(使用pageInfo的相关属性)
