<if test="startTime!=null and startTime!=''">
        and logintime <![CDATA[>=]]> #{startTime}
      </if>
      <if test="endTime!=null and endTime!=''">
        and logintime <![CDATA[<=]]> #{endTime}
      </if>

　　

原因：这是因为原因是mybatis 中对于时间参数进行比较时的一个bug. 如果拿传入的时间类型参数与空字符串''进行对比判断则会引发异常. 所以在上面的代码中去掉空字符串判断, 只保留非空判断就正常了。

解决办法：去掉！=''

<if test="startTime!=null ">
  and logintime <![CDATA[>=]]> #{startTime}
</if>
<if test="endTime!=null ">
  and logintime <![CDATA[<=]]> #{endTime}
</if>
