Bitbucket CI/CD 管道中的 SQLite 数据库“无法打开数据库文件”

Question

在我的 Spring boot 项目（使用 gradle 作为构建工具）中，我使用 SQLite 数据库。数据库文件位于项目根目录

/db/

目录下：

my-project/
 - db/
    - mydb.db  ## This db file is generated by JPA when run the project
 - src/
    - main
      - java/
        ...
 - bitbucket-pipelines.yml

在我的

src/main/resouces/application.yml

我有：

spring:
  datasource:
    url: jdbc:sqlite:file:./db/mydb.db?cache=shared
    driver-class-name: org.sqlite.JDBC
    username: foo
    password: foo
  jpa:
    show-sql: true
    database-platform: org.hibernate.community.dialect.SQLiteDialect
    hibernate:
      ddl-auto: update

项目根目录下的文件夹

/db/

最初实际上是空的，当本地运行该项目时，数据库文件

mydb.db

是由JPA自动创建的。应用程序在本地也运行良好，数据库连接已建立。

现在我想在 CI/CD 管道中构建项目。在我的简单

bitbucket-pipelines.yml

中，我只有构建项目的步骤：

image: gradle:7.6.0-jdk17

definitions:
  steps:
    - step: &build-it
        name: Build project
        caches:
          - gradle
        script:
          - bash ./gradlew build
        artifacts:
          - 'build/**'
pipelines:
  default:
    - step: *build-it

将代码推送到bitbucket存储库后，管道被触发，但最终出现错误，提示无法打开数据库文件。由于完整的堆栈跟踪太长，我在下面添加了最有趣的行：

> Task :test
MyApplicationTests > testRestEndpoint() FAILED
    java.lang.IllegalStateException: Failed to load ApplicationContext for [WebMergedContextConfiguration@50b624da testClass = com.foo.MyApplicationTests, locations = [], classes = [com.foo.MyApplication], contextInitializerClasses = [], activeProfiles = [], propertySourceLocations = [], propertySourceProperties = ["org.springframework.boot.test.context.SpringBootTestContextBootstrapper=true"], contextCustomizers = [org.springframework.boot.test.autoconfigure.actuate.observability.ObservabilityContextCustomizerFactory$DisableObservabilityContextCustomizer@1f, org.springframework.boot.test.autoconfigure.properties.PropertyMappingContextCustomizer@4b3fa0b3, org.springframework.boot.test.autoconfigure.web.servlet.WebDriverContextCustomizerFactory$Customizer@6e950bcf, [ImportsContextCustomizer@1764e45e key = [org.springframework.boot.test.autoconfigure.web.servlet.MockMvcAutoConfiguration, org.springframework.boot.test.autoconfigure.web.servlet.MockMvcWebClientAutoConfiguration,

看起来我的管道无法打开 SQLite 数据库文件。

有人可以指导我如何重构我的

bitbucket-pipelines.yml

以使数据库文件可以通过管道访问吗？

Answer 1

根据堆栈跟踪中的错误消息

No suitable driver found for ${DATASOURCE_URL}

，问题似乎是，至少对于测试而言，您的应用程序正在使用环境变量

DATASOURCE_URL

来获取要连接的数据库url，而在您的管道中，您不这样做没有定义它。

定义它的一种方法是添加一个导出到脚本的步骤：

image: gradle:7.6.0-jdk17

definitions:
  steps:
    - step: &build-it
        name: Build project
        caches:
          - gradle
        script:
          - export DATASOURCE_URL='jdbc:sqlite:file:./db/mydb.db?cache=shared'
          - bash ./gradlew build
          
        artifacts:
          - 'build/**'
pipelines:
  default:
    - step: *build-it
