首先來一下代碼StringBuffer sql = new StringBuffer();        sql.append("select");        sql.append("        f.id,");        sql.append("        f.foodName,");        sql.append("        f.price,");        sql.append("        f.mprice,");        sql.append("        f.intro,");        sql.append("        f.img,");        sql.append("        t.id,");        sql.append("        t.typeName ");        sql.append("from ");        sql.append("        OS_foodInfo f, ");        sql.append("        OS_foodType t ");        sql.append("where 1=1");        sql.append("        and f.foodType_id=t.id ");        List<Object> list = new ArrayList<Object>();        if (foodType_id > 0) {            sql.append("and f.foodType_id = ? ");            list.add(foodType_id);        }        if (foodName != null && !"".equals(foodName.trim())) {            sql.append("and f.foodName like '%");            sql.append("?");            sql.append("%' ");            list.add(foodName);        }        sql.append("limit ?,?");然后來運行后的錯誤java.sql.SQLException: Wrong number of parameters: expected 3, was given 4 Query: select f.id, f.foodName, f.price, f.mprice, f.intro, f.img, t.id, t.typeName from OS_foodInfo f, OS_foodType t where 1=1 and f.foodType_id=t.id and f.foodType_id = ? and f.foodName like '%?%' limit ?,? Parameters: [1, 蝦, 0, 6]是模糊拼接有問題嗎？
