在我的 Spring Boot 项目中，我正在尝试设置 liquibase 并在开发、测试和生产数据库之间使用它。liquibase.properties除了将凭据从 HashiCorp Vault传递到文件之外，一切似乎都运行良好。我可以 application.properties毫无问题地访问凭据，但我不能liquibase.properties存档。我有以下文件，我想从密码库动态传递 URL 和凭据。

liquibase.properties

changeLogFile=src/main/resources/liquibase-changeLog.xml
url=jdbc:mysql://localhost:3306/oauth_reddit
username=tutorialuser
password=tutorialmy5ql
driver=com.mysql.jdbc.Driver
referenceUrl=hibernate:spring:org.baeldung.persistence.model
  ?dialect=org.hibernate.dialect.MySQLDialect
diffChangeLogFile=src/main/resources/liquibase-diff-changeLog.xml

liquibase.properties由 liquibase 直接使用。我不确定 spring 是否以某种方式修改了liquibase.properties，它可能仅由 maven 插件使用。所以你需要在 liquibase 中创建一些额外的解析器，它能够使用 Vault 或者只是忘记 liquibase.properties 并使用 spring 的属性。

下面的代码从保险库注入数据源中获取数据库详细信息，该数据源被 liquibase 用于连接和执行脚本

构建.gradle.kts

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

plugins {
    id("org.springframework.boot") version "2.4.4"
    id("io.spring.dependency-management") version "1.0.11.RELEASE"
    kotlin("jvm") version "1.4.31"
    kotlin("plugin.spring") version "1.4.31"
}

group = "com.db"
version = "0.0.1-SNAPSHOT"
java.sourceCompatibility = JavaVersion.VERSION_1_8

configurations {
    compileOnly {
        extendsFrom(configurations.annotationProcessor.get())
    }
}

repositories {
    mavenCentral()
}

dependencies {
    implementation("org.springframework.boot:spring-boot-starter-data-jpa")
    implementation("org.springframework.cloud:spring-cloud-starter-bootstrap:3.0.2")
    implementation("org.jetbrains.kotlin:kotlin-reflect")
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8")
    implementation("org.liquibase:liquibase-core:4.3.2")
    implementation(files("libs/ojdbc6.jar"))
    implementation("org.springframework.cloud:spring-cloud-starter-vault-config:3.0.2")
}

tasks.withType<KotlinCompile> {
    kotlinOptions {
        freeCompilerArgs = listOf("-Xjsr305=strict")
        jvmTarget = "1.8"
    }
}

tasks.withType<Test> {
    useJUnitPlatform()
}

引导程序属性

spring.cloud.vault.application-name=database-config
spring.cloud.vault.token=XXXXX
spring.cloud.vault.scheme=http
spring.cloud.vault.kv.enabled=true
spring.cloud.vault.host=localhost
spring.cloud.vault.port=8200

应用程序属性

logging.level.liquibase=DEBUG
spring.liquibase.change-log=classpath:db/changelog.xml
spring.liquibase.enabled=true

VaultDBConfig

import org.springframework.boot.context.properties.ConfigurationProperties

@ConfigurationProperties("db")
class VaultDBConfig {
    var username: String? = null
    var password: String? = null
    var url: String? = null
}

数据库配置

import oracle.jdbc.pool.OracleDataSource
import java.sql.SQLException
import org.slf4j.Logger
import org.slf4j.LoggerFactory
import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.Configuration
import org.springframework.context.annotation.Primary
import org.springframework.context.annotation.Profile
import org.springframework.core.env.Environment
import javax.sql.DataSource

@Configuration
class DatabaseConfig(private val dbDetails: VaultDBConfig, private val environment: Environment) {

    val logger: Logger = LoggerFactory.getLogger(DatabaseConfig::class.java)

    @Primary
    @Bean
    @Throws(SQLException::class)
    fun dataSource(): DataSource? {
        val oracleDataSource = OracleDataSource()
        oracleDataSource.setURL(dbDetails.url)
        oracleDataSource.setUser(dbDetails.username)
        oracleDataSource.setPassword(dbDetails.password)
        return oracleDataSource
    }
}

在 application.kt 中启用配置属性

@SpringBootApplication
@EnableConfigurationProperties(VaultDBConfig::class)
class ConfigApplication

fun main(args: Array<String>) {
    runApplication<ConfigApplication>(*args)
}

保险柜插入

vault kv put secret/database-config db.username=xxx db.password=xxx dp.url=xxx
