无法使用 jOOQ 编写 Postgres 数组列

Question

我有一个带有 String[] 和 Time[] 数组列的 Table。从 table 读取工作正常。但是当我尝试创建记录时...

MyTableRecord r = txJooq.newRecord(MY_TABLE);
r.setId(id);
r.setStringArr("foo", "bar");
r.setTimeArr(LocalTime.of(7, 0), LocalTime.of(10, 0));
r.store();

...我得到以下异常。

org.jooq.exception.DataAccessException: SQL [null]; Can't infer the SQL type to use for an instance of [Ljava.lang.String;. Use setObject() with an explicit Types value to specify the type to use.

jOOQ 似乎生成了无效的 SQL 语句。它创造了

values (
  ...
  ('foo', 'bar'), 
  ...
);

而不是正确的

values (
  ...
  '{"foo", "bar"}', 
  ...
);

我正在使用：

org.jooq: jooq: 3.9.1
org.jooq：jooq-codegen：3.9.1
org.postgresql：postgresql：9.4.1212
postgres 9.6

Answer 1

愚蠢的我，我用错误的 SQL 方言配置了 jOOQ

new DefaultConfiguration().set(SQLDialect.POSTGRES)

成功了
