为什么我按上一页会直接跳到登录页面
<table border="0" cellspacing="0" cellpadding="0" align="center">
<tr>
<td align="right">
<span>第<s:property value="currPage"/>/<s:property value="totalPage"/>页</span>
<span>总记录数:<s:property value="totalCount"/> 每页显示:<s:property value="pageSize"/></span>
<span>
<s:if test="currPage != 1">
<a href="${pageContext.request.contextPath }/user_findAll.action?currPage=1">[首页]</a>
<a href="${pageContext.request.contextPath }/user_findAll.action?currPage=<s:property value="currPage-1"/>">[上一页]</a>
</s:if>
<s:if test="currPage != totalPage">
<a href="${pageContext.request.contextPath }/user_findAll.action?currPage=<s:property value="currPage+1"/>">[下一页]</a>
<a href="${pageContext.request.contextPath }/user_findAll.action?currPage=<s:property value="totalPage"/>">[尾页]</a>
</s:if>
</span>
</td>
</tr>
