mybatis xml里面报错The content of elements must consist of well-formed character data or markup.

  核对xml里面的sql语句是否出现了”<”、”>”、”&”等字符，如果出现了需要进行转义。

<     <
>     >
&     &
'      &aops;
"     "

  修改前的sql语句

		select sum(A.sum_yhzcjz)/count(*) from (
		select @rownum:=@rownum+1,dj_yhzc.* 
		from (select @rownum:=0) t1 ,
		(select * from dj_yhzc  where sum_yhzcjz is not null  order by dj_yhzc.sum_yhzcjz desc) dj_yhzc 
		where @rownum < (select round((count(*)-1)/2) from dj_yhzc where sum_yhzcjz is not null ))A

  修改后的sql语句

		select sum(A.sum_yhzcjz)/count(*) from (
		select @rownum:=@rownum+1,dj_yhzc.* 
		from (select @rownum:=0) t1 ,
		(select * from dj_yhzc  where sum_yhzcjz is not null  order by dj_yhzc.sum_yhzcjz desc) dj_yhzc 
		where @rownum <(select round((count(*)-1)/2) from dj_yhzc where sum_yhzcjz is not null ))A
