UPSERT in PostgreSQL using jOOQ

我正在尝试使用jOOQ库在PostgreSQL中执行UPSERT。

为此，我目前正在尝试在jOOQ中实现以下SQL语句：https://stackoverflow.com/a/6527838

到目前为止，我的代码看起来像这样：

public class UpsertExecutor {

    private static final Logger logger = LoggerFactory.getLogger(UpsertExecutor.class);

    private final JOOQContextProvider jooqProvider;

    @Inject
    public UpsertExecutor(JOOQContextProvider jooqProvider) {
        Preconditions.checkNotNull(jooqProvider);

        this.jooqProvider = jooqProvider;
    }

    @Transactional
    public <T extends Record> void executeUpsert(Table<T> table, Condition condition, Map<? extends Field<?>, ?> recordValues) {
        /*
         * All of this is for trying to do an UPSERT on PostgreSQL. See:
         * https://stackoverflow.com/a/6527838
         */

        SelectConditionStep<Record1<Integer>> notExistsSelect = jooqProvider.getDSLContext().selectOne().from(table).where(condition);
        SelectConditionStep<Record> insertIntoSelect = jooqProvider.getDSLContext().select(recordValues).whereNotExists(notExistsSelect);

        try {
            int[] result = jooqProvider.getDSLContext().batch(
                jooqProvider.getDSLContext().update(table).set(recordValues).where(condition),
                jooqProvider.getDSLContext().insertInto(table).select(insertIntoSelect)
            ).execute();

            long rowsAffectedTotal = 0;
            for (int rowsAffected : result) {
                rowsAffectedTotal += rowsAffected;
            }

            if (rowsAffectedTotal != 1) {
                throw new RuntimeException("Upsert must only affect 1 row. Affected: " + rowsAffectedTotal + ". Table: " + table + ". Condition: " + condition);
            }
        } catch (DataAccessException e) {
            if (e.getCause() instanceof BatchUpdateException) {
                BatchUpdateException cause = (BatchUpdateException)e.getCause();

                logger.error("Batch update error in upsert.", cause.getNextException());
            }

            throw e;
        }
    }
}

但是，此代码不会编译，因为 select（） 不支持值映射：

SelectConditionStep<Record> insertIntoSelect = jooqProvider.getDSLContext().select(recordValues).whereNotExists(notExistsSelect);

问题

如何为 select（） 提供一组预定义的值，如下所示：？SELECT 3, 'C', 'Z'

我设法让代码工作。下面是完整的类：

public class UpsertExecutor {

    private static final Logger logger = LoggerFactory.getLogger(UpsertExecutor.class);

    private final JOOQContextProvider jooqProvider;

    @Inject
    public UpsertExecutor(JOOQContextProvider jooqProvider) {
        Preconditions.checkNotNull(jooqProvider);

        this.jooqProvider = jooqProvider;
    }

    @Transactional
    public <T extends Record> void executeUpsert(Table<T> table, Condition condition, List<FieldValue<Field<?>, ?>> recordValues) {
        /*
         * All of this is for trying to do an UPSERT on PostgreSQL. See:
         * https://stackoverflow.com/a/6527838
         */

        Map<Field<?>, Object> recordValuesMap = new HashMap<Field<?>, Object>();
        for (FieldValue<Field<?>, ?> entry : recordValues) {
            recordValuesMap.put(entry.getFieldName(), entry.getFieldValue());
        }

        List<Param<?>> params = new LinkedList<Param<?>>();
        for (FieldValue<Field<?>, ?> entry : recordValues) {
            params.add(val(entry.getFieldValue()));
        }

        List<Field<?>> fields = new LinkedList<Field<?>>();
        for (FieldValue<Field<?>, ?> entry : recordValues) {
            fields.add(entry.getFieldName());
        }

        SelectConditionStep<Record1<Integer>> notExistsSelect = jooqProvider.getDSLContext().selectOne().from(table).where(condition);
        SelectConditionStep<Record> insertIntoSelect = jooqProvider.getDSLContext().select(params).whereNotExists(notExistsSelect);

        try {
            int[] result = jooqProvider.getDSLContext().batch(
                jooqProvider.getDSLContext().update(table).set(recordValuesMap).where(condition),
                jooqProvider.getDSLContext().insertInto(table, fields).select(insertIntoSelect)
            ).execute();

            long rowsAffectedTotal = 0;
            for (int rowsAffected : result) {
                rowsAffectedTotal += rowsAffected;
            }

            if (rowsAffectedTotal != 1) {
                throw new RuntimeException("Upsert must only affect 1 row. Affected: " + rowsAffectedTotal + ". Table: " + table + ". Condition: " + condition);
            }
        } catch (DataAccessException e) {
            if (e.getCause() instanceof BatchUpdateException) {
                BatchUpdateException cause = (BatchUpdateException)e.getCause();

                logger.error("Batch update error in upsert.", cause.getNextException());
            }

            throw e;
        }
    }
}

但是，使用该参数感觉不是很干净。关于如何做到这一点有什么更好的想法吗？List<FieldValue<Field<?>, ?>> recordValues
