moo*_*t94 4 postgresql hibernate gradle docker spring-boot
正在开发 java spring boot 应用程序。我们的 postgres 数据库是容器化的。我可以让 hibernate 自动创建表,但无法让它自动运行 import.sql 文件。你能帮我弄清楚发生了什么事吗?
这是 build.gradle 文件:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath('org.springframework.boot:spring-boot-gradle-plugin:2.1.6.RELEASE')
}
}
apply plugin: 'application'
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
mainClassName = 'idealab.IdeaLabMain'
bootJar {
baseName = 'idealab'
excludeDevtools = false //TODO(e-carlin): In production this should be removed
}
repositories {
mavenCentral()
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
dependencies {
compile('org.springframework.boot:spring-boot-devtools') // TODO(e-carlin): Make sure this isn't pulled in in the production jar
implementation('org.springframework.boot:spring-boot-starter-data-jpa')
implementation('org.springframework.boot:spring-boot-starter-web')
implementation('org.postgresql:postgresql')
testCompile('junit:junit')
}

这是 application.properties 文件:
logging.level.org.hibernate=DEBUG
debug=true
spring.jpa.database=POSTGRESQL
spring.datasource.platform=postgres
spring.datasource.url=jdbc:postgresql://localhost:5432/postgres
spring.datasource.username=postgres
spring.datasource.password=docker
spring.jpa.show-sql=true
spring.jpa.generate-ddl=true
hibernate.hbm2ddl.auto=create # TODO(e-carlin): This will wipe away the
# database data. Good for dev not for prod
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true

这是位于 src/main/resources 中的 import.sql 文件:
buildscript {
repositories {
mavenCentral()
}
dependencies {

}
}
apply plugin: 'application'

excludeDevtools = false //TODO(e-carlin): In production this should be removed

这是该模型的一个示例:
logging.level.org.hibernate=DEBUG
debug=true
spring.jpa.database=POSTGRESQL
spring.datasource.platform=postgres
spring.datasource.url=jdbc:postgresql://localhost:5432/postgres
spring.datasource.username=postgres
spring.datasource.password=docker
spring.jpa.show-sql=true
spring.jpa.generate-ddl=true
hibernate.hbm2ddl.auto=create # TODO(e-carlin): This will wipe away the
# database data. Good for dev not for prod
spring.jpa.properties.hibernate.jdbc.lob.non_contextual_creation=true

感谢您的任何帮助,您可以提供!
import.sqlhibernate.hbm2ddl.auto是 Hibernate 本机功能,只有设置为create或create-drop时才会执行。
但现在你正在设置:
spring.jpa.generate-ddl=true
hibernate.hbm2ddl.auto=create

spring.jpa.generate-ddl=true将hibernate.hbm2ddl.auto=update在幕后布景。hibernate.hbm2ddl.auto=create无效并且没有任何效果,因为所有有效的 springboot JPA 属性都应以spring.jpa 所以最后,将hibernate.hbm2ddl.auto被设置为更新,因此import.sql不会被执行。
您可以通过更改为简单地修复它hibernate.hbm2ddl.auto=create:
spring.jpa.properties.hibernate.hbm2ddl.auto=create

注意:spring.jpa.generate-ddl将被覆盖spring.jpa.properties.hibernate.hbm2ddl.auto,因此您可以简单地将其删除。
