JSF分页查询实现-优快云博客

本文介绍了一种使用JSF框架实现的分页查询功能，包括前端页面设计、后端业务逻辑处理及数据库交互过程。文章详细展示了如何通过JSF的`h:commandLink`和`page:pagination`组件来实现数据的分页显示，并介绍了如何配置`OutBean`及`OutServiceImpl`以完成数据的查询和分页。

首先要点一下查找才有数据
1.listChunkOut.jsp
<h:form id="searchForm">
<h:commandLink action="#{outBean.listChunkOut}"

styleClass="highLightLink" id="search">

<h:outputText value="查找" />

</h:commandLink>
<page:pagination>
<table>
<tr><td>字段１：</td><td>字段2：</td><td>字段3：</td></tr>
<c:forEach var="out" items="#{listChunk.list}">
<tr><td>取字段１：out.* </td><td>取字段2：</td><td>取字段3：

</td></tr>
</c:forEach>
</table>
</page:pagination>
2.OutBean.java
public String listChunkOut()
{
  outService.listChunkOut(searchConditions);
  return "listChunkOut";
}
3.OutServiceImpl.java
public ListChunk listChunkOut(SearchConditions conditions)
{
  BusinessSearchConditions

bconditions=conditions.validConditions(Arrays.asList(new String[]

{"I_outid"}));
return outDAO.listChunkOut(bconditions);
}

protected Map<String,String> conditions;

searchConditions.conditions['personName']

searchConditions
BusinessSearchConditions
<managed-bean>
  <managed-bean-name>searchConditions</managed-bean-name>
  <managed-bean-class>
   com.whlongyi.common.condition.SearchConditions
  </managed-bean-class>
  <managed-bean-scope>session?</managed-bean-scope>
</managed-bean>
jsf中baking Bean的配置
bean中有一对象，需要配置
<managed-property>
   <property-name>searchConditions</property-name>
   <value>#{searchConditions}</value>
</managed-property>
</managed-bean>???
