jdbc在模糊搜索时候报错：Parameter index out of range

jdbc在模糊搜索时候报错：Parameter index out of range 

源代码如下

String sql = "select g.id,g.goodsname,g.price,g.offset,g.time,g.counts,g.cid  from goods g,(select g1.id, concat(g1.goodsname,c1.cname) words  "
				+ "from goods g1,category c1) t where words like '%?%' and  t.id = g.id  order by g.id limit ?,? ;";

报错问题如下

 Parameter index out of range (3 > number of parameters, which is 2).

修改如下

String sql = "select g.id,g.goodsname,g.price,g.offset,g.time,g.counts,g.cid  from goods g,(select g1.id, concat(g1.goodsname,c1.cname) words  "
				+ "from goods g1,category c1) t where words like concat('%',?,'%') and  t.id = g.id  order by g.id limit ?,? ;";
