Good day all who interested :) I have some problem with jOOQ.
I need to generate jOOQ entities from PostgreSQL table. It has a field with bigint[] type. jOOQ Gradle plugin(I'm using this one https://github.com/etiennestuder/gradle-jooq-plugin) doesn't have supports of array DateType, so the only way is to use custom types with forced types
// jooq config in build.gradle
customTypes {
customType {
name = "BigintArrayBinder"
type = "Long[]"
converter = "ru.stdev.tskad.yandexnavigator.binder.BigintArrayBinder"
}
}
forcedTypes {
forcedType {
name = "BigintArrayBinder"
includeExpression = '.*'
includeTypes = 'ARRAY'
}
}
And this is the implementation of this binder with its converter
public class BigintArrayConverter implements Converter<Object[], Long[]> {
@Override
public Long[] from(Object[] t) {
return t == null ? new Long[]{} : (Long[]) t;
}
@Override
public Object[] to(Long[] u) {
return u == null || u.length == 0 ? new Object[]{} : u;
}
@Override
public Class<Object[]> fromType() {
return Object[].class;
}
@Override
public Class<Long[]> toType() {
return Long[].class;
}
}

System.out.print("value -> ");
System.out.println(Arrays.toString(value));
PgArray pgArray = new PgArray(connection, longOid, Arrays.toString(value));
ctx.statement().setArray(ctx.index(), pgArray);
}
// Getting a bigint[] value from a JDBC ResultSet and converting that to a Long[]

}
}
So, it's compiling and worked fine for selects queries. But if I try to make insert I have this exception

The first thing that confuses me it's necessary to create BaseConnection. I can get a connection from DslContext, but it returns a HikariProxyConnection. So, it's not applying to PgArray, it requires BaseConnection. Then, I need to give it an oid, that equals 20 to Long type. And then i have to give a array as string or byte array. And as result i have ArrayIndexOutOfBoundsException. I made many attempts to find decision of this problem, but i failed. What i do wrong? I feel like I'm doing something wrong, but I don't understand what exactly.
You should try Connection.createArrayOf()
Eg ctx.statement().getConnection().createArrayOf(...)
