java - 创建 EntityManagerFactory 时出现 ArrayIndexOutOfBoundsException

Question

除了 spring-data-jpa 之外，我还使用了 Spring Framework。我想通过创建 bean 来自动创建我的 DataSource 和 EntityManagerFactory ，因为据我所知，不可能在纯 Spring 上下文中使用包含所有这些内容的属性文件。

如果有任何问题，请不要怀疑我的配置。这只是我从互联网上获得的一堆代码，因为我不太了解 hibernate/spring-data-jpa/jpa 及其调用方式。

所以我现在的问题是我想创建我的 EntityManagerFactory 但是，它抛出 ArrayIndexOutOfBoundsException 并且我不知道它从哪里来以及如何摆脱它。

堆栈:

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;
    }

此外，我认为在 de.nebelniek.database.user 中提供实体会非常有用，但我只有一个:

@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;

}

话虽这么说，感谢任何帮助我的人。 <3

我在 Guava 库中发现了我的问题。 刚刚将 guava 版本降级到 30.1.1-jre，工作正常。
