springboot中mapper.xml出现The content of elements must consist of well-formed character data or markup

 

<select id="select_fy" resultType="User">
	select *
	from (select ROWNUM r,USER_NAME,USER_ID
		from (select ROWNUM,USER_NAME,USER_ID from YH_USER y where ROWNUM < {after}))
	where r >=  #{before}
</select>

最后发现是因为mybatis中的mapper.xml中 不能存在 <  >  符号

在代码中加入 <![CDATA[ 符号 ]]>

即可
