Question

我使用带有嵌入式H2数据库的Spring Data JPA。我有两个sql文件：

schema.sql

CREATE TABLE SINGER (
    ID INT NOT NULL AUTO_INCREMENT,
    FIRST_NAME VARCHAR(60) NOT NULL,
    LAST_NAME VARCHAR(60) NOT NULL,
    BIRTH_DATE DATE,

    CONSTRAINT UQ_SINGER UNIQUE (FIRST_NAME, LAST_NAME),
    PRIMARY KEY (ID)
);

CREATE TABLE ALBUM(
    ID INT NOT NULL AUTO_INCREMENT,
    SINGER_ID INT,
    TITLE VARCHAR(100) NOT NULL,
    RELEASE_DATE DATE,

    CONSTRAINT UQ_ALBUM UNIQUE (TITLE),
    CONSTRAINT FK_ALBUM FOREIGN KEY (SINGER_ID) REFERENCES SINGER (ID),
    PRIMARY KEY (ID)
);

data.sql

INSERT INTO SINGER (FIRST_NAME, LAST_NAME, BIRTH_DATE) VALUES ('John', 'Mayer', '1977-10-16');
INSERT INTO SINGER (FIRST_NAME, LAST_NAME, BIRTH_DATE) VALUES ('Eric', 'Clapton', '1945-03-30');
INSERT INTO SINGER (FIRST_NAME, LAST_NAME, BIRTH_DATE) VALUES ('Jorn', 'Butler', '1975-04-01');

INSERT INTO ALBUM (SINGER_ID, TITLE, RELEASE_DATE) VALUES (1, 'The Search For Everything', '2017-01-20');
INSERT INTO ALBUM (SINGER_ID, TITLE, RELEASE_DATE) VALUES (1, 'Battle Studies', '2009-11-17');
INSERT INTO ALBUM (SINGER_ID, TITLE, RELEASE_DATE) VALUES (2, 'From The Cradle', '1994-09-13');

数据库配置：

@Bean
public DataSource dataSource() {
    try {
        EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
        return builder.setType(EmbeddedDatabaseType.H2)
                .addScripts("db/schema.sql", "db/data.sql")
                .build();
    } catch (Exception ex) {
        log.error("Cannot create DataSource", ex);
        return null;
    }
}

问题是：：执行schema.sql时未执行data.sql。所有测试（查找所有数据，按ID查找，插入，更新，删除）均成功通过

似乎data.sql已成功执行，但是只要插入一些数据，我就看不到数据（在测试方法中）。

更新：我有以下测试方法（它们均成功通过，但是在testFindAll（）中我看不到任何数据）：

@Test
void testFindAll() {
    List<Singer> singers = singerRepository.findAll();
    assertNotNull(singers);
    displayAllSingers(singers);
}

@Test
void testInsert() {
    Singer singer = createSinger();
    singerRepository.insert(singer);
    assertNotNull(singer.getId());

    displayAllSingers(singerRepository.findAll());
}

您不必担心SingerRepository的实现，它可以正常工作（在testInsert（）中，您可以看到singerRepository.findAll（），并且它可以工作，我看到插入的歌手）。
