[英]Spring boot is not saving data of data.sql file into h2 database on initialization

架構.sql
drop table if exists employee_model_read;
create table EMPLOYEE_MODEL_READ(
ID BIGINT AUTO_INCREMENT PRIMARY KEY,
AGE INTEGER(10),
DOJ VARCHAR(255),
NAME VARCHAR(255),
ROLE VARCHAR(255)
);
數據.sql
insert into employee_model_read(AGE,DOJ,NAME,ROLE) values (23,'25-09-2020','RAM','Front End Developer');
應用程序.properties
spring.datasource.url=jdbc:h2:mem:batchjob
spring.h2.console.enabled=true
spring.datasource.username=sa
spring.datasource.password=
spring.datasource.driverClassName=org.h2.Driver
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.batch.job.enabled=false
data.sql 文件的數據未在 H2 數據庫中選取。 H2 數據庫在 rest 其他情況下工作正常。 我正在使用 JPA 進行其他與數據庫相關的操作。 如果您想要其他文件,請告訴我,以便我上傳。 請幫助我知道這是行不通的方式。
將此行添加到我的application.properties文件后,代碼就可以工作了。
spring.jpa.hibernate.ddl-auto= update
我不完全了解所有上下文。 為什么不在 application.yml 中設置ddl-auto
config 的值。 如下圖。 就我而言,它正在工作。
請注意,如果將
ddl-auto
設置為驗證,則必須在 schema.sql 的列和實體的字段之間進行匹配。
spirng:
jpa:
hibernate:
ddl-auto: validate
Spring 文檔說In a JPA-based app, you can choose to let Hibernate create the schema or use schema.sql, but you cannot do both. Make sure to disable spring.jpa.hibernate.ddl-auto if you use schema.sql.
