Question

我使用Spring MVC/ Hibernate应用程序并在一段时间后重新启动它以继续工作。这次我收到以下错误，

我在Database中有几张表，下面提供了hibernate_sequence表，

我见过有人在论坛中建议填写hibernate_sequence表如下，我做了这个并没有解决它的问题。

Insert into wallet.hibernate_sequence(next_val) values(0)

我使用Java annotation based配置，下面提供了数据库连接，

    @Bean
    public DataSource dataSource() {

        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("com.mysql.cj.jdbc.Driver");

        // dataSource.setUrl("jdbc:mysql://localhost:3306/wallet?createDatabaseIfNotExist=true");
        dataSource.setUrl("jdbc:mysql://localhost:3306/wallet");
        dataSource.setUsername("testuser");
        dataSource.setPassword("testpassword");

        return dataSource;
    }

    Properties hibernateProperties() {

        Properties properties = new Properties();
//        properties.setProperty("hibernate.hbm2ddl.auto", "create-drop");
        properties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");
        properties.setProperty("hibernate.id.new_generator_mappings", "false");
        return properties;
    }

这是WalletInfo pojo，

    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @NotNull
    @Column(name = "name")
    private String name;

    @NotNull
    @Column(name = "address")
    private String address;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }
}

这里的问题是什么以及如何解决？

Answer 1

如果您未在数据库中维护任何序列，请使用 @GeneratedValue(strategy = javax.persistence.GenerationType.IDENTITY ) 它会自动为您的桌子保留一个唯一的标识。

javax.persistence.GenerationType.IDENTITY

IDENTITY选项只允许数据库为您的应用程序生成唯一的主键。没有序列或表用于维护主键信息，相反，数据库只会选择一个适当的唯一编号，以便Hibernate分配给实体的主键。使用MySQL，选择表中可用的第一个最低编号的主键，尽管这种行为可能因数据库而异。

org.hibernate.id.enhanced.TableStructure - 无法读取hi值
