Configure the org.jooq.conf.Settings.backslashEscaping property - jooq

Question

In the book "Beginning jOOQ" by Tayo Koleoso it is written:
Caution For your own peace of mind, go ahead and configure the
org.jooq.conf.Settings.backslashEscaping property on
your Settings object. MySQL and some versions of PostgreSQL
support non-standard escape characters that can cause you a lot of
grief when you least expect it. This property lets jOOQ properly handle
this “feature” from MySQL.
The problem is that to the best of my ability I can't find in the book how toconfigure this.

#Controller

public class StartController {
#GetMapping("/")
public void start() {
try (Connection connection = DriverManager.
getConnection("jdbc:mysql://localhost/test?user=testdb&password=testdb")) {
DSLContext context = DSL.using(connection, SQLDialect.MYSQL);
ResultQuery resultQuery = context.
resultQuery("SELECT * FROM edens_car.complete_car_listing");
List<CompleteVehicleRecord> allVehicles =
resultQuery.fetchInto(CompleteVehicleRecord.class);
} catch (SQLException sqlex) {
assert true;
}
}
}
I just organised the Spring Controller for my convenience, don't pay attention to it.

Answer 1

Adapting your example code
You can pass custom Settings to one of the DSL.using() overloads, specifically:
DSLContext context = DSL.using(connection, SQLDialect.MYSQL, settings);
Noting that these methods are just convenience for creating your own DefaultConfiguration
A Spring Boot DefaultConfigurationCustomizer
Alternatively, if you're using Spring Boot, then this article shows how to use a DefaultConfigurationCustomizer, e.g.:
#Bean
public DefaultConfigurationCustomizer configurationCustomiser() {
return (DefaultConfiguration c) -> c.settings()
.withBackslashEscaping(...);
}
