Hibernate/H2外鍵拋出org.h2.jdbc.JdbcSQLException

我正在嘗試使用H2數據庫進行單元測試。我的實際數據庫是MYSQL，所以我用H2的MYSQL方言。一旦hbm文件被讀取/加載，問題就會出現。由於H2或Hibernate試圖改變表格，所以外鍵/關聯會失去作用，或者看起來如此。Hibernate/H2外鍵拋出org.h2.jdbc.JdbcSQLException

DB腳本：

DROP SCHEMA IF EXISTS `amr` ; 
CREATE SCHEMA IF NOT EXISTS `amr`; 

-- ----------------------------------------------------- 
-- Table `amr`.`classA` 
-- ----------------------------------------------------- 
DROP TABLE IF EXISTS `amr`.`classA` ;CREATE TABLE IF NOT EXISTS `amr`.`classA` (
    `classA_id` INT(11) NOT NULL , 
    `name` VARCHAR(56) NOT NULL , 
    PRIMARY KEY (`classA_id`)); 

-- ----------------------------------------------------- 
-- Table `amr`.`classB` 
-- ----------------------------------------------------- 
DROP TABLE IF EXISTS `amr`.`classB` ;CREATE TABLE IF NOT EXISTS `amr`.`classB` (
    `classB_id` INT(11) NOT NULL , 
    `name` VARCHAR(45) NOT NULL , 
    `classA_id` INT(11) NOT NULL , 
    PRIMARY KEY (`classB_id`) , 
    INDEX `fk_classB_service_provider_classA1` (`classA_id` ASC) , 
    CONSTRAINT `fk_classB_service_provider_classA1` 
    FOREIGN KEY (`classA_id`) 
    REFERENCES `amr`.`classA` (`classA_id`) 
    ON DELETE NO ACTION 
    ON UPDATE NO ACTION);

例外，我得到：

H2網址：

-------------------編輯/找到問題--------------- -------------------

幾乎從頭開始重新評估一切，發現我不正確地將下面的屬性添加到我的上下文文件中：

創建刪除

在其中一個論壇中，指導我的H2上下文配置指向使用它，因爲它「在會話關閉後刪除模式」。

所以我對這個屬性的無知導致了一個教訓。

@Thomas Mueller - 非常感謝您在這件事上的時間和協助。

如果您改用H2方言（並刪除MODE = MYSQL），它會起作用嗎？我想你無論如何都需要有兩個Hibernate配置（一個用於測試，一個用於生產）。 Hibernate應該能夠抽象數據庫特定的功能，因此如果在生產中使用不同的數據庫，則不需要太在意。 –

當我更改爲h2方言時，它對我的ddl語法不滿意： org.h2.jdbc.JdbcSQLException：未知數據類型：「FK_CLASSB_SERVICE_PROVIDER_CLASSA1」; SQL語句： CREATE TABLE IF NOT EXISTS'amr'.'classB'（ 'classB_id' INT（11）NOT NULL， 'name' VARCHAR（45）NOT NULL， 'classA_id' INT（11）NOT NULL， PRIMARY KEY（'classB_id'） INDEX'fk_classB_service_provider_classA1'（'classA_id' ASC），約束'fk_classB_service_provider_classA1' 外鍵（'classA_id'）參考'amr'。'classA'（'classA_id'） ON DELETE NO ACTION ON UPDATE NO ACTION） – user1655798

是的，我有單獨的休眠配置，但試圖維護一組數據庫腳本文件 – user1655798

您已使用僅適用於MySQL的腳本。下面的腳本應該是更多的跨數據庫，根據我的測試它適用於H2，MySQL和PostgreSQL（我沒有測試其他數據庫）。我還用INT替換了MySQL特定的INT(11)。腳本假設架構/數據庫amr已經存在：

drop table if exists amr.classB; 
drop table if exists amr.classA; 
CREATE TABLE IF NOT EXISTS amr.classA (
    classA_id INT(11) NOT NULL, 
    PRIMARY KEY (classA_id) 
); 
CREATE TABLE IF NOT EXISTS amr.classB ( 
    classB_id INT(11) NOT NULL , 
    name VARCHAR(45) NOT NULL , 
    classA_id INT(11) NOT NULL , 
    PRIMARY KEY (classB_id) 
); 
CREATE INDEX fk_classB_service_provider_classA1 
    ON amr.classA(classA_id ASC); 
ALTER TABLE amr.classB 
    ADD CONSTRAINT fk_classB_service_provider_classA1 
    FOREIGN KEY (classA_id) 
    REFERENCES amr.classA(classA_id) 
    ON DELETE NO ACTION ON UPDATE NO ACTION;

然後，在Hibernate的配置，使用H2的H2模式。
