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

我在数据库中有几个表，下面提供了hibernate_sequence表，
我在论坛上看到有人建议按如下方式填写 hibernate_sequence 表，我这样做并没有解决问题。
Insert into wallet.hibernate_sequence(next_val) values(0)
我使用基于Java注解的配置，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，
@Entity
@Table(name = "wallet_info")
public class WalletInfo {
@Id
@Column(name = "id")
@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;
}
}
这是什么问题，如何解决？
最佳答案
如果您不在数据库中维护任何序列，则使用
@GeneratedValue(strategy = javax.persistence.GenerationType.IDENTITY)
它会自动为您的 table 维护一个唯一的标识。
javax.persistence.GenerationType.IDENTITY
IDENTITY 选项只允许数据库为您的应用程序生成一个唯一的主键。没有使用序列或表来维护主键信息，相反，数据库只会为 Hibernate 选择一个合适的、唯一的编号来分配给实体的主键。对于 MySQL，会选择相关表中可用的第一个编号最小的主键，尽管这种行为可能因数据库而异。
