创建 EntityManagerFactory 时出现 ArrayIndexOutOfBoundsException

Posted 2023-02-26

【中文标题】创建 EntityManagerFactory 时出现 ArrayIndexOutOfBoundsException

【英文标题】：ArrayIndexOutOfBoundsException when creating a EntityManagerFactory

【发布时间】：2021-12-19 00:40:48

【问题描述】：

除了spring-data-jpa，我还在使用Spring Framework。我想通过创建 bean 来创建我的 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。

如果有什么不合理的地方，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，因为我不喜欢 hibernate/spring-data-jpa/jpa 以及它的调用方式。

所以我现在的问题是我想创建我的EntityManagerFactory，但是它抛出了一个ArrayIndexOutOfBoundsException，我不知道它从哪里得到以及如何摆脱它。

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;
    

另外我认为在de.nebelniek.database.user 中提供实体会非常有用，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;

所以，话虽如此，感谢任何帮助我的人。

【问题讨论】：

可能与此有关？最好升级您的版本并尝试。 github.com/wildfly/jandex/issues/80

@KishoreBandi 我已经得到了版本 2.2.3.Final，因为他说应该在那里修复。

@JanHerzog 你能解决这个问题吗？我有同样的问题，由于某种原因只出现在 docker 中。

【参考方案1】：

我在番石榴库中发现了我的问题。 只是将番石榴的版本降级到 30.1.1-jre 并且它工作正常。
