Spring Boot 应用程序卡在“Hikari-Pool-1 - 正在启动...”答案

【问题标题】：Spring Boot Application gets stuck on "Hikari-Pool-1 - Starting..."Spring Boot 应用程序卡在“Hikari-Pool-1 - 正在启动...”
【发布时间】：2018-12-16 23:36:32
【问题描述】：

我正在尝试运行连接到 PostgreSQL 数据库的 Spring Boot 应用程序。但是，当涉及到 Hikari 连接池初始化时，它只是卡住了，什么也没有发生。 HikariPool-1 - Starting... 出现在日志中，然后什么也没有发生。

我的apllication.properties：

spring.datasource.url=jdbc:postgresql://127.0.0.1:55491/TodoAppDatabase
spring.datasource.username=admin
spring.datasource.password=root
spring.datasource.hikari.connection-timeout=10000
spring.datasource.hikari.driver-class-name=org.postgresql.Driver
spring.datasource.hikari.maximum-pool-size=100
spring.data.jpa.repositories.enabled=true
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto = update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQL94Dialect
spring.jpa.properties.hibernate.cache.use_query_cache=true
spring.jpa.properties.hibernate.connection.provider_class=com.zaxxer.hikari.hibernate.HikariConnectionProvider

我该如何解决这个问题？

【问题讨论】：

嗨，这个错误解决了吗。我面临同样的问题。请回复
HikariCP和postgresql驱动的有效版本有哪些？

标签： spring postgresql spring-boot

【解决方案1】：

普通的 postgresql 端口是 5432，所以我假设您也将其配置为 55491。

通过您的 postgresql 客户端使用 psql -h 127.0.0.1 -p 55491 -d TodoAppDatabase -U admin 仔细检查这一点

最后你可以将 HikariCP 设置为 DEBUG 模式，这样你就可以看到它使用了哪些参数。

如果您的属性文件确实是 apllication.properties，那么这也可能是一个问题，因为 spring boot 只会自动拾取 application.properties。

【讨论】：

【解决方案2】：

在运行 jar 文件时尝试传递此参数：

-Djava.security.egd=file:/dev/../dev/urandom

【讨论】：

【解决方案3】：

在 application.properties 中进行以下更改应该可以正常工作：

spring.datasource.url=jdbc:postgresql://localhost:5432/<dbName>

还要确保，您未选中“固定端口号”框，在 pgAdmin 配置框中，请参阅截图

【讨论】：

【解决方案4】：

就我而言，这是网络连接的问题。如果遇到此问题，请确保您可以访问任何已配置的服务器。

telnet host 5432 将让您连接以查看是否存在到 DB 服务器的路由。

【讨论】：

【解决方案5】：

在我的例子中，spring.datasource.hikari.initializationFailTimeout 设置为一个非常高的值，3600000（1 小时）。这本身并不是配置错误，但它隐藏了真正的问题，因为应用程序在启动时挂起。

调整该值后，我得到了一个更易于理解的堆栈跟踪，这使我得出结论，在这种情况下，我无法使用我可能通过 jHipster 获得的默认 MariaDB 驱动程序配置。

到目前为止，我只在 AWS EC2 上的 MySQL8 和 Ubuntu 20 上看到过一个非常奇怪的问题。在本地，我通过 Docker 运行 Ubuntu 和 MySQL8 没有问题。

【讨论】：

【解决方案6】：

在我的情况下（Windows 10），它需要三个步骤：

停止运行的postgresql服务
以管理员身份打开命令提示符并终止端口5432上的所有服务
从服务窗口重新启动 postgresql 服务。

你很好。

【讨论】：

【解决方案7】：

它可能无法连接到数据库。尝试重新启动您的数据库实例并确保它可以访问。

【讨论】：

【解决方案8】：

我遇到了同样的问题，并通过删除 application.properties 文件中的 AUTO_SERVER=true 行解决了这个问题，因此在删除后应用程序照常运行。

删除#spring.datasource.url=jdbc:... AUTO_SERVER=true中的AUTO_SERVER=true

这样一来，您就失去了从终端等不同来源访问数据库的功能，这意味着您无法在应用运行时从终端访问数据库（即使用数据库）

但如果您需要AUTO_SERVER=true，请重新启动您的电脑，然后数据库将重新启动，这可能会解决您的问题（这不是开玩笑）。
