logged query does not escape the newline ("\n") character in the json field, which breaks sql parsing

[George Li]

Setup:

• p6spy:3.8.6
• spring-boot: 1.5.16
• Mysql: 5.7

CREATE TABLE `json_test` (
  `id` bigint(20) NOT NULL,
  `metadata` json DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8

The query logged by p6spy is

insert into json_test (id, metadata) values (1, '{"field": "\n"}');

The newline character will fails the sql parsing

mysql> insert into json_test (id, metadata) values (1, '{"field": "\n"}');
ERROR 3140 (22032): Invalid JSON text: "Invalid escape character in string." at position 10 in value for column 'json_test.metadata'.

Note that

• The actual query sent through jdbc is successful
• the above query is fine if the field is text

mysql> insert into text_test (id, metadata) values (1, '{"field": "\n"}');
Query OK, 1 row affected (0.01 sec)
