java - Hikari 抛出错误 Property url does not exist on target class org.postgresql.ds.PPGoolingDataSource

Question

我正面临来自 kubernetes 集群的这个错误。虽然它在我的本地服务器上运行得很好。这是我的SpringBoot App的application.yml

Spring :

datasource:
    dataSourceClassName: org.postgresql.ds.PGPoolingDataSource
    url: jdbc:postgresql://${POSTGRES_HOST}:5432/test_db
    databaseName: test_db
    poolName: SpringBootHikariCP
    username: ${POSTGRES_USER}
    password: ${POSTGRES_PASSWORD}
    testWhileIdle: true
    validationQuery: SELECT 1
jpa:
    database-platform: org.hibernate.dialect.PostgreSQL82Dialect
    openInView: false
    show_sql: true
    generate-ddl: true
    hibernate:
        ddl-auto: update
        naming-strategy: org.hibernate.cfg.ImprovedNamingStrategy
        use-new-id-generator-mappings: true
    properties:
        hibernate.cache.use_second_levelt_cache: false
        hibernate.cache.use_query_cache: false
        hibernate.generate_statistics: true
        hibernate.hbm2ddl.auto: validate

这是我的 Hikari 配置。

            HikariConfig config = new HikariConfig();
            config.setDataSourceClassName(dataSourceClassName);
            config.addDataSourceProperty("url", url);
            config.addDataSourceProperty("user", user);
            config.addDataSourceProperty("password", password);

            return new HikariDataSource(config);

我已经在没有 Hikari 的情况下检查了 kubernetes 的数据库连接，它运行良好。所以连接没有问题。请帮我解决这个问题。我坚持了几天。谢谢

${POSTGRES_HOST} 期待一个 system environment variable您可能在特定机器中缺少，例如添加它:

export POSTGRES_HOST="1.1.1.1"
