Row map does not support entrySet

[atjiu]

        String sql = "SELECT * FROM blog";
        try(Connection con = MyDao.sql2o.open()) {
            List<Map<String, Object>> blogs = con.createQuery(sql)
                    .executeAndFetchTable()
                    .asList();
            return success(blogs);
        }

When I execute the code above, an exception is thrown Row map does not support entrySet

            int index = columnNameToIdxMap.get(colum);
            map.put(colum, values[index]);

@biezhi 你的这个有点复杂了。
