通过Writer写入数百万个字符串是否会影响java字符串池的内存和性能?

假设我有一段代码,它将字符串流回到一个拥有数百万行数据的客户机。每个写操作上的所有字符串都会被截取,从而影响java内存吗?如果是,为什么在我的情况下,它会或不被拘留?

查询将返回数百万行

try (BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(response.getOutputStream()))) {

            writer.write("[");
            jdbcTemplate.query(sql, new Object[]{name,  age},

                    rs -> {

                        try {

                            writer.write("{\"id1\":" + rs.getInt("id1") + ",");

                            writer.write("\"id2\":" + rs.getInt("id2") + "}");

                        } catch (IOException e) {

                            log.log(Level.ERROR, e);

                        }

                    });

            writer.write("]");

        } catch (IOException e) {

            throw e;

        }
