JOOQ在executeInsert（）之后，需要知道自动生成的ID

Question

使用JOOQ（与sqlite3一起）。

有一些代码如下所示：（根据文档中的示例修改：https://www.jooq.org/doc/latest/manual/sql-execution/fetching/pojos/)

// A "mutable" POJO class
public class MyBook {
  public int id;
  public String title;
}

// Create a new POJO instance
MyBook myBook = new MyBook();
// myBook.id = 10; <-- Id is NOT set here because the database auto-generates it
myBook.title = "Animal Farm";

// Load a jOOQ-generated BookRecord from your POJO
BookRecord book = create.newRecord(BOOK, myBook);

// Insert it (explicitly)
create.executeInsert(book);

// What is value of the auto-generated id?

此时，我需要知道从数据库自动生成的ID。

• 有什么想法吗？
• 还是在保存之前需要设置ID？

使用executeInsert（）似乎无法恢复ID：

// Insert it (explicitly)
create.executeInsert(book);

然而，使用<代码>记录。存储功能：

book.store()

以下是如何从POJO转到记录，以便可以存储PJO，然后使用生成的ID获取更新的POJO：

// A "mutable" POJO class
public class MyBook {
  public int id;
  public String title;
}

// Create a new POJO instance
MyBook myBook = new MyBook();
// myBook.id = 10; <-- Id is NOT set here because the database auto-generates it
myBook.title = "Animal Farm";

// Load a jOOQ-generated BookRecord from your POJO
BookRecord book = create.newRecord(BOOK, myBook);

// Insert it (implicitly) using the BookRecord instead of create.executeInsert()
book.store();            // <--- THIS IS THE KEY DIFFERENCE

// Get new Book POJO from the BookRecord
MyBook newBook = book.into(MyBook.class);

// This is also a handy function to get the Record as Map, 
//   which is easier to view in the debugger
Map<String, Object> bookMap = book.intoMap();
