java - Hsql异常: type not found or user lacks privilege: DATETIMEOFFSET

Question

我有一个 Java 8、Spring Boot 2 应用程序，其中 JPA 实体连接到 MS SQL Server 数据库。我正在尝试使用 HSQLDB (2.3.3) 创建集成测试，如果我不包含审核信息(创建日期、上次更新等)，该测试可以正常工作。

这是我收到的错误消息:

Caused by: org.hsqldb.HsqlException: type not found or user lacks privilege: DATETIMEOFFSET

据我了解，“未找到类型或用户缺乏权限”错误是通用错误，可能由多种原因引起。在这种情况下，我知道如果不是尝试将 datetimeoffset 列添加到表中，一切都会正确运行。

在网上寻找答案时，我发现this documentation至少支持一些 MS SQL 日期/时间类型和函数，但是 this (two-year-old) answer表明 HSQLDB 对 MS SQL 的支持有限。我还没有找到任何专门讨论 HSQLDB 与 datetimeoffset 数据类型相关的文档。

我的表创建和数据插入脚本:

    DROP SCHEMA TEST IF EXISTS;
    CREATE SCHEMA TEST;

    CREATE TABLE TEST.Example (
      ID int IDENTITY NOT NULL,
      Name nvarchar(30) NOT NULL,
      Description nvarchar(1000),
      CreatedDate datetimeoffset(7) NOT NULL
    );

    INSERT INTO TEST.Example (ID, Name, Description, CreatedDate) 
    VALUES (1, 'First', 'This is the first example.', '2019-04-18 12:00:00 -05:00');

我的数据源配置:

    config:
      datasource:
        jdbc-url: jdbc:hsqldb:mem:testdb;sys.syntax_mss=true
        driver-class-name: org.hsqldb.jdbc.JDBCDriver
        validation-query: SELECT 1
        test-on-borrow: false
        test-while-idle: true
        time-between-eviction-runs-millis: 60000
        max-active: 10

我的实体:

    @Data
    @Entity
    @Table(name = "Example", schema = "TEST")
    public class ExampleEntity {    
        @Id
        @Column(name = "ID", unique = true, nullable = false)
        @GeneratedValue(strategy = GenerationType.IDENTITY)
        private int id;

        @Column(name = "Name", nullable = false)
        private String name;

        @Column(name = "Description")
        private String description;

        @Column(name = "CreatedDate", nullable = false)
        private LocalDateTime createdDate;    
    }

我的存储库:

    public interface ExampleRepository extends CrudRepository<ExampleEntity, Integer> {
    }

我的集成测试配置:

    @Configuration
    @EnableJpaRepositories(
        basePackages = "com.test.example.repository",
        entityManagerFactoryRef = "integrationTestEntityFactory",
        transactionManagerRef = "integrationTestTransactionManager")
    public class IntegrationTestConfig {
        @Bean
        @ConfigurationProperties(prefix = "config.datasource")
        public DataSource integrationTestDatasource() {
            return new EmbeddedDatabaseBuilder()
                .addScript("scripts/schema.sql")
                .build();
        }

        @Bean
        public LocalContainerEntityManagerFactoryBean integrationTestEntityFactory(final DataSource integrationTestDatasource) {

            HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
            vendorAdapter.setDatabase(Database.SQL_SERVER);
            vendorAdapter.setShowSql(false);

            LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
            factory.setJpaVendorAdapter(vendorAdapter);
            factory.setPackagesToScan("com.test.example.entity");
            factory.setDataSource(integrationTestDatasource);
            return factory;
        }

        @Bean
        public PlatformTransactionManager integrationTestTransactionManager(final LocalContainerEntityManagerFactoryBean integrationTestEntityFactory) {
            JpaTransactionManager transactionManager = new JpaTransactionManager();
            transactionManager.setEntityManagerFactory(integrationTestEntityFactory.getObject());
            return transactionManager;
        }

        @Bean
        public NamedParameterJdbcTemplate integrationTestJdbcTemplate(final DataSource integrationTestDatasource) {
            return new NamedParameterJdbcTemplate(integrationTestDatasource);
        }
    }

Answer 1

对于 datetimeoffset SQL 类型，您应该使用 java.time.OffsetDateTime Java 类型:

    @Column(name = "CreatedDate", nullable = false)
    private OffsetDateTime createdDate; 

这是如果您的类路径中有 2.2 版本的 JPA。否则你需要创建一个 custom converter
