mybatis xml中特殊字符处理

Posted 2020-10-01

1，CDATA区：

它的全称为character data,以"<![CDATA[ "开始，以" ]]>" 结束，在两者之间嵌入不想被解析程序解析的原始数据，解析器不对CDATA区中的内容进行解析，而是将这些数据原封不动地交给下游程序处理。

2，特殊字符 ：

xml 中表示：   <= 小于等于、    >= 大于等于 需加  这样的标记：     <![CDATA[   ]]>      xml中有&的符号，需要

<![CDATA[&]]>这样表示&

<= 小于等于 ：<![CDATA[ <= ]]>

>= 大于等于：<![CDATA[  >=  ]]>

3，一些特殊字符也可用下面的替代符号所代替。

 特殊字符   替代符号

     &            &amp;

     <            &lt;

     >            &gt;

     "             &quot;

     ‘              &apos;
