Question

将sql文件中的日期时间戳插入内存数据库中的h2失败。

我正在尝试在Spring应用程序启动时从.sql文件插入日期。

pom.xml如下所示：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.4.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>
<dependencies>
    ....
    <dependency>
        <groupId>com.h2database</groupId>
        <artifactId>h2</artifactId>
        <scope>runtime</scope>
    </dependency>
    ....
</dependencies>

属性文件如下所示：

spring:
  datasource:
    url: jdbc:h2:mem:my_db;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE
    platform: h2
    username: sa
    password:
    driverClassName: org.h2.Driver
  jpa:
    database-platform: org.hibernate.dialect.H2Dialect
    hibernate:
      ddl-auto: create-drop
    properties:
      hibernate:
        show_sql: true
        use_sql_comments: true
        format_sql: true
  h2:
    console:
      enabled: true
      path: /console
      settings:
        trace: false
        web-allow-others: false

实体如下：

@Data
@Entity
@Table(
    name = "class_room"
)
@NoArgsConstructor
public class Classroom
{

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue
    private Long id;

    @Column(nullable = false)
    @DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME)
    private ZonedDateTime dateCreated = ZonedDateTime.now();

    @Column(nullable = false)
    @NotNull(message = "Classroom Name can not be null!")
    private String classroomName;

    ....

}

当我使用以下命令运行应用程序时：

mvn clean install spring-boot:run

我收到以下错误：

Cannot create inner bean '(inner bean)#16f15ae9' of type [org.springframework.orm.jpa.SharedEntityManagerCreator] while setting bean property 'entityManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#16f15ae9': Cannot resolve reference to bean 'entityManagerFactory' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory': Post-processing of FactoryBean's singleton object failed; nested exception is org.springframework.jdbc.datasource.init.ScriptStatementFailedException: Failed to execute SQL script statement #1 of URL [file:/my_drive/app_server/target/classes/data.sql]:

插入class_room（id，date_created，...）值（1，＆＃39; 2018-03-15 18:47:52.69＆＃39;，...）;嵌套异常是 org.h2.jdbc.JdbcSQLException：十六进制字符串包含非十六进制性格：＆＃34; 2018-03-15 18：47：52.69＆＃34 ;; SQL语句：

data.sql看起来如下：

insert into class_room (id, date_created, ... ) values (1, '2018-03-15 18:47:52.69', ... )

或

insert into class_room (id, date_created, ... ) values (1, now(), ... )

和还尝试了http://www.h2database.com/html/functions.html#current_timestamp

insert into class_room (id, date_created, ... ) values (1, CURRENT_TIMESTAMP(), ... )

我试过，从sql插入时间戳的各种方式，但不幸的是sql无法将数据放入内存数据库。

任何帮助将不胜感激！
