liquibase 中的自定义属性（迁移到较新版本后）导致 Spring 启动失败

Question

我不得不在 Spring-boot maven 项目中迁移到更新版本的 Liquibase 核心，之后，我得到了一个 ArrayIndexOutOfBoundsException。

属性定义：

<property dbms="db2,derby,mysql,h2,mssql" name="autoid" value="BIGINT"/>
<property dbms="oracle" name="autoid" value="BIGINT" />
<property dbms="postgresql" name="autoid" value="SERIAL"/>

抛出异常

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'liquibase' defined in class path resource [com/unymira/kfirst/application/config/DatabaseManagementConfig.class]: Invocation of init method failed; nested exception is java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1

属性使用示例

<column autoIncrement="true" name="id" type="${autoid}">
<constraints nullable="false" primaryKey="true" primaryKeyName="${db_prefix}instancepk" />
</column>

我不得不提一下，这段代码是以前的代码，对于旧的 liquibase 没有任何问题。

有人对我做错了什么有建议吗？

Answer 1

这是一个不太优雅的解决方法，而这个错误是开放的。

免责声明：这会给您的测试增加一点开销，并且可能并不适合所有人。您需要手动更新您的测试架构。

假设您在 liquibase 迁移步骤上有以下数据库：

CREATE TABLE foo(
  id text PRIMARY KEY,
  name text not null,
  hobbies text[] not null,
  locals jsonb,
  status boolean not null default false,
  date_time_updated timestamp,
  date_time_created timestamp NOT NULL
);

在您的 SpringBoot 休息资源中的测试/资源上，您可以使用以下内容创建一个 testschema.sql：

CREATE TABLE foo(
  id character varying(255) DEFAULT RANDOM_UUID() NOT NULL,
  name character varying(255) NOT NULL,
  hobbies ARRAY NOT NULL,
  locals json NOT NULL,
  status boolean,
  date_time_updated timestamp without time zone,
  date_time_created timestamp without time zone NOT NULL
);

爱好是：

<property name="json_type" value="json" dbms="postgresql"/>

我在我的实体中拥有

@Table(name = "foo")
@TypeDef(name = "json", typeClass = JsonBinaryType.class)
@TypeDef(
  name = "string-array",
  typeClass = StringArrayType.class
)
public class Foo {
...
@Type(type = "string-array")
@Column(name = "hobbies", columnDefinition = "text[]")
private String[] hobbies;

@Type(type = "json")
@Column(name = "locals", columnDefinition = "json")
private JsonNode locals;

然后你可以简单地为你的 repo 写一个@DataJpaTest：

@ExtendWith(SpringExtension.class)
@DataJpaTest
@TestPropertySource(properties = {
  "spring.jpa.hibernate.ddl-auto=validate"
})
public class TestFooRepository {

  @Autowired
  private DataSource dataSource;
  @Autowired
  private JdbcTemplate jdbcTemplate;
  @Autowired
  private EntityManager entityManager;
  @Autowired
  private FooRepository fooRepository;

  @Test
  void injectedComponentsAreNotNull() {
    assertThat(dataSource).isNotNull();
    assertThat(jdbcTemplate).isNotNull();
    assertThat(entityManager).isNotNull();
    assertThat(notificationRepository).isNotNull();
  }

  @Test
  public void testShouldSaveTheCorrectObject() throws JsonProcessingException {
    Foo expected = buildTestFoo();
    fooRepository.save(expected);
    final Optional<Foo> actual = notificationRepository.findById("<foo_id>");
    Assert.assertNotNull(actual);
    Assert.assertTrue(actual.isPresent());

    Assert.assertEquals(expected.getId(), actual.get().getId());
  }
}

希望这会有所帮助。

Answer 2

就我而言，这是因为从 3.6.0 开始，在 MariaDB 上运行时我必须使用 dbms="mariadb"，而在之前的版本中它曾经被标识为 "mysql"。

由此更改引起：https://github.com/liquibase/liquibase/commit/7fb10ed7ae599cab585d4a6a4ec891ad7b91ecf1#diff-a07fbaf7b19fd286fef2e684648d5159

Answer 3

我在使用 Open JDK 11 时遇到了类似的问题。切换到 Oracle JDK 11 后，liquibase:diff 运行正常。很奇怪。
