String code;  String contractCode;  %>  <%  code = (String)request.getAttribute("code");  contractCode = URLEncoder.encode(code);//为解决乱码问题而设计的，所传参数没有中文不需要  request.setAttribute("contractCode",contractCode);    %>  <table class="listViewPaginationTdS1"><tr>  <div>    <s:if test="pagination.totalPages != 0">  <s:url action="%{#request.url}" id="first">  <s:param name="pagination.currentPage" value="1"></s:param>  <s:param name="contract.contractCode" value="#request.contractCode"/>  </s:url>  <s:url action="%{#request.url}" id="next" >  <s:param name="pagination.currentPage"  value="pagination.currentPage+1">  </s:param>  <s:param name="contract.contractCode" value="#request.contractCode"/>  </s:url>  <s:url action="%{#request.url}" id="prior" >  <s:param name="pagination.currentPage"  value="pagination.currentPage-1"></s:param>  <s:param name="contract.contractCode" value="#request.contractCode"/>  </s:url>  <s:url action="%{#request.url}" id="last">  <s:param name="pagination.currentPage" value="pagination.totalPages"></s:param>  <s:param name="contract.contractCode" value="#request.contractCode"/>  </s:url>  <s:if test="pagination.currentPage == 1">  <td>  <span class="current">首页</span>  <span class="current">上一 页</span></td>  </s:if>  <s:else>  <td>  <s:a href="%{first}">首页</s:a>  <s:a href="%{prior}">上一页</s:a> </td>  </s:else>  <s:if  test="pagination.currentPage == pagination.totalPages || pagination.totalPages == 0">  <td>  <span class="current">下一页</span>  <span class="current">末u-26507 </span> </td>  </s:if>  <s:else>  <td>  <s:a href="%{next}">下一页</s:a>&nbsp;&nbsp;                    <s:a href="%{last}">末页</s:a> </td>  </s:else>  <td>  <s:form action="%{#request.url}?contract.contractCode=%{#request.contractCode}" theme="simple"  cssStyle="display:inline">  <span class="jumplabel">跳转到</span>  <s:hidden name="pagination.totalPages" value="%{pagination.totalPages}"></s:hidden>  <input type="text" name="pagination.currentPage" size="2"  onblur="selectPage(this)" />  <span class="jumplabel">页</span>  </s:form>  </td>  <td>  <span class="jumplabel">共<s:property  value="pagination.totalRows" />条</span>  <span class="jumplabel">当前是第 <s:property  value="pagination.currentPage" />/<s:property value="pagination.totalPages"/>页</span>    </td>  </s:if>    </div>    </tr></table>  fenye.js的内容如下  function trim(str){  return str.replace(/(^\s*)|(\s*$)/g, "");  }    function selectPage(input){    var value = trim(input.value);  if(value == ""){  return;  }    if(/\d+/.test(value)){    input.form.submit();  return;  }  alert("请输入正确的页数");  input.focus();    }  注意：pagination.totalRows、pagination.totalPages、pagination.currentPage等的.后面的属性写法一定要和类里面的属性一致，否则在页面无法显示  3、在dao里面调用  public List<ContractEntryDetail> queryDetail(String code,int currentPage) {  String sql = "......";  List<ContractEntryDetail> list = null;     pagination = new Pagination(sql,currentPage,5,jdbcTemplate,new ContractEntryDetailRowMapper());     list = pagination.getResultList();//pagination 是dao的一个属性，dao内包含其get、set方法     return list;  }  4、Action里调用  public String execute(){  list = queryContractFenluDetailService.queryDetaiList(newSc3,pagination.getCurrentPage());  pagination = queryContractFenluDetailService.getPagination();  ActionContext ac = ActionContext.getContext();  ac.put("code", newSc3);  ac.put("url","fenlu.action");  ac.put("pagination",pagination);  ac.put("list", list);  return "success";    }
