創建 EntityManagerFactory 時出現 ArrayIndexOutOfBoundsException

Question

除了spring-data-jpa之外，我還使用Spring Framework 。 我想通過創建 bean 以 promatically 的方式創建我的DataSource和EntityManagerFactory ，因為根據我的知識，不可能在純 Spring 上下文中使用包含所有這些東西的屬性文件。

如果有什么沒有意義，請不要懷疑我的配置。 這只是我從互聯網上獲得的一堆代碼，因為我對 hibernate/spring-data-jpa/jpa 以及它的調用方式並不了解。

所以我現在的問題是我想創建我的EntityManagerFactory但是，它拋出一個ArrayIndexOutOfBoundsException並且我不知道它來自哪里以及如何擺脫它。

堆：

我的配置：

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        vendorAdapter.setShowSql(true);
        vendorAdapter.setGenerateDdl(true); //Auto creating scheme when true
        vendorAdapter.setGenerateDdl(true);

        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
        factory.setJpaVendorAdapter(vendorAdapter);
        factory.setPackagesToScan("de.nebelniek.database.user");
        factory.setDataSource(dataSource());
        return factory;
    }

    @Bean
    public PlatformTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
        JpaTransactionManager txManager = new JpaTransactionManager();
        txManager.setEntityManagerFactory(entityManagerFactory);
        return txManager;
    }

    private DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("org.mariadb.jdbc.Driver");
        dataSource.setUsername("");
        dataSource.setPassword("");
        dataSource.setUrl("jdbc:mariadb://example.com:3306/database?createDatabaseIfNotExist=true");
        return dataSource;
    }

另外我認為在de.nebelniek.database.user提供實體會非常有用，我只有一個：

@Entity
@Getter
@Setter
@Builder
@AllArgsConstructor
@RequiredArgsConstructor
public class CloudUser {

    @Id
    @GeneratedValue
    private long id;
    private UUID uuid;
    private String lastUserName;
    private Date lastLogin;
    private String twitchId;
    private boolean subbed;

}

所以，話雖如此，感謝任何幫助我的人。 <3

我在番石榴圖書館發現了我的問題。 剛剛將番石榴的版本降級到 30.1.1-jre，它工作正常。
