分页实现方法

pagination : 502_3@502_3@5502_3@5,10,15,20,50 ],

每次页面操作或者查询请求CURD时响应头部都会带着页面page和rows属性。所以后台可以指定接收参数进行分页。

例如在初始化的时候。我们会创建一个page的 bean用来接收前台传入的page 和 row、

502_3@ 502_3@

}

}@H_502_3@

再定义一个 pagination来方便json数组操作。

502_3@ 502_3@

@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@<span style="color: #0000ff;"&gt;private@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@ List<Object><span style="color: #000000;"&gt; rows;
@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@<span style="color: #0000ff;"&gt;private@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@<span style="color: #000000;"&gt; String total;

@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@<span style="color: #0000ff;"&gt;public@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@<span style="color: #000000;"&gt; List  getRows() {
    @H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@<span style="color: #0000ff;"&gt;return@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@<span style="color: #000000;"&gt; rows;
}
@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@<span style="color: #0000ff;"&gt;public@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@ <span style="color: #0000ff;"&gt;void@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@<span style="color: #000000;"&gt; setRows(List  rows) {
    @H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@<span style="color: #0000ff;"&gt;this@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@.rows =<span style="color: #000000;"&gt; rows;
}
@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@<span style="color: #0000ff;"&gt;public@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@<span style="color: #000000;"&gt; String getTotal() {
    @H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@<span style="color: #0000ff;"&gt;return@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@<span style="color: #000000;"&gt; total;
}
@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@<span style="color: #0000ff;"&gt;public@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@ <span style="color: #0000ff;"&gt;void@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@<span style="color: #000000;"&gt; setTotal(String total) {
    @H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@<span style="color: #0000ff;"&gt;this@H_<a href="/tag/502/" target="_blank" class="keywords">502</a>_3@.total =<span style="color: #000000;"&gt; total;
}

}@H_502_3@

Pagination p = 502_3@502_3@=502_3@502_3@502_3@ String json = "{\"total\":" + p.getTotal() + ",\"rows\":" + JSON.toJSONString(p.getRows(),SerializerFeature.DisableCircularReferenceDetect) + "}"502_3@ 502_3@ json;

直接调用find方法从数据库取出数据就可以了。结果会转化成json数据集然后显示在前台页面的。

我自己写了一个简单的分页实现，比上边方法直接，直观。

@RequestMapping("/find_test"502_3@502_3@ 502_3@502_3@502_3@502_3@ Account account = 502_3@502_3@502_3@502_3@502_3@后台的 page row http会包含在post头中@H_502_3@ 502_3@ currentPage = Integer.parseInt(request.getParameter("page"502_3@502_3@ pageSize = Integer.parseInt(request.getParameter("rows"502_3@502_3@查询条件的序列成map来管理@H_502_3@ String date_start = request.getParameter("date_start")== 502_3@?"":request.getParameter("date_start"502_3@= request.getParameter("date_end")== 502_3@?"":request.getParameter("date_end"502_3@= request.getParameter("orgid")== 502_3@?"":request.getParameter("orgid"502_3@= request.getParameter("customer.id")== 502_3@?"":request.getParameter("customer.id"502_3@ searchmap = 502_3@ HashMap502_3@"date_start"502_3@"date_end"502_3@"orgid"502_3@"customer.id"502_3@502_3@分页显示@H_502_3@ List dayRecruits = 502_3@502_3@502_3@ total = 502_3@502_3@"text/html;charset=utf-8"502_3@502_3@502_3@ String json = "{\"total\":"+total+",\"rows\":"+JSON.toJSONString(dayRecruits,SerializerFeature.DisableCircularReferenceDetect)+"}"502_3@502_3@502_3@

牵扯到的hql关键语句为

Query query =502_3@-1)*pageSize); 502_3@502_3@ query.setMaxResults(pageSize); 502_3@502_3@ List dayrecruit =502_3@502_3@ dayrecruit;
