<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;如上@FilterGroup 的value 必须是[OR]或者[AND]开头，没有标记@FilterGroup的字段等价于标记了@FilterGroup(value = "[AND]")。[AND]、[OR]后面的字符串为GROUP_NAME，默认的GROUP_NAME为空字符串。如上"[OR]a"可以直接使用"[OR]"，有多个[OR]或者[AND]则需要加上不同的NAME。</p>
<p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;如上@FilterGroup 的value 用.来构建树结构，没有标记@FilterGroup的字段等价于标记了@FilterGroup(value = "")。</p>
