H2 Spring Boot - 不创建具有 LocalDateTime 属性的表

Question

我有 Spring Boot 3.2 和 H2 用于开发。 H2 正在创建一些表，但不是全部。

我最初使用 MySQL 数据库开发我的项目 - 但后来在 Spring Boot 中创建了一个新的开发配置文件，并将 mem 中的数据库更改为 H2。

正是在这一点上，一些实体没有获得在H2数据库中创建的表。

例如：

健康检查

@AllArgsConstructor
@NoArgsConstructor
@ToString
@Entity
@Data
@JsonIgnoreProperties({"hibernateLazyInitalizer", "handler"})
@SequenceGenerator(name = "health_check_seq", sequenceName = "HEALTH_CHECK_SEQ", initialValue = 100, allocationSize = 50)
@Table(name = "health_check")
public class HealthCheck {

    @Id
    @GeneratedValue(strategy = SEQUENCE, generator = "health_check_seq")
    private Long id;

    @JsonManagedReference
    @ManyToOne(fetch = FetchType.EAGER, optional = false)
    private Bird bird;
   
    @JsonManagedReference
    @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true, mappedBy = "healthCheck")
    private List<Task> tasks;

    @JsonFormat(pattern = "yyyy-MM-dd HH:mm")
    private LocalDateTime catchDateTime;


    @JsonBackReference
    private Point<G2D> location;

    @ManyToOne
    @JoinColumn(name = "holder_id")
    private User holder;

应用程序属性

spring.datasource.url=jdbc:h2:file:~/IdeaProjects/test/h2mem/data;MV_STORE=false;AUTO_SERVER=TRUE
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=password
spring.jpa.hibernate.ddl-auto=update
spring.sql.init.data-locations=classpath:/datadev.sql

更新了app.props：

spring.datasource.url=jdbc:h2:mem:testdb;INIT=CREATE SCHEMA IF NOT EXISTS TEST_SCHEMA_NAME
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=password
spring.jpa.hibernate.ddl-auto=update

我尝试在 datadev.sql 中插入数据，但失败，因为

HEALTH_CHECK

表不存在。

如何让H2为所有实体创建表？

Answer 1

根据您提供的资源，您的代码似乎是正确的。我认为问题可能出在 application.properties 文件中。请确保您设置了以下属性：“

spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.username=sa
spring.datasource.password=password
spring.jpa.hibernate.ddl-auto=update

@Entity
@Table(name = "health_check")
@AllArgsConstructor
@NoArgsConstructor
@ToString
@Data
public class HealthCheck {

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "health_check_seq")
    @SequenceGenerator(name = "health_check_seq", sequenceName = "HEALTH_CHECK_SEQ", initialValue = 100, allocationSize = 50)
    private Long id;

    @JsonManagedReference
    @ManyToOne(fetch = FetchType.EAGER, optional = false)
    @JoinColumn(name = "bird_id") // Make sure to specify the correct column name
    private Bird bird;

    @JsonManagedReference
    @OneToMany(cascade = CascadeType.ALL, orphanRemoval = true, mappedBy = "healthCheck")
    private List<Task> tasks;

    @JsonFormat(pattern = "yyyy-MM-dd HH:mm")
    private LocalDateTime catchDateTime;

    @JsonBackReference
    @Column(columnDefinition = "geometry(Point, 4326)") // Customize this based on your database and GIS library
    private Point location;

    @ManyToOne
    @JoinColumn(name = "holder_id")
    private User holder;

    // Getter and setter methods for all fields
}
