从 spring 引导应用程序连接到本地 MySQL 数据库时出错
Error connecting to local MySQL database from spring boot application
我正在使用 Intellij IDEA，开发 spring 引导应用程序并尝试连接到 docker 中的 mysql 数据库 运行。我在 application.properties 文件中设置了我的连接属性。问题是它似乎没有在启动时使用这些属性。如下所示，它正在尝试连接到我在项目中任何地方都没有引用的另一个数据库。似乎 jdbc 字符串是从其他地方获取的，但我不确定它可能在哪里。我已经使缓存无效并重新启动，并且还删除了 .gradle 中的缓存文件夹，因为我认为连接字符串来自某个地方的缓存，但仍然出现相同的错误。其他人以前遇到过这个问题吗？从下面的错误可以看出，它正在尝试连接到连接字符串中未指定的数据库。

Spring Boot 使用非常特殊的 PropertySource 顺序，该顺序旨在允许合理地覆盖值，按以下顺序考虑属性：
- 命令行参数。
- 来自 java 的 JNDI 属性：comp/env.
- Java 系统属性 (System.getProperties())。
- OS 环境变量。
- 只具有随机属性的 RandomValuePropertySource。*。
- 打包的 jar 文件之外的特定于配置文件的应用程序属性（application-{profile}.properties 和 YAML 变体）
- 打包在您的 jar 中的特定于配置文件的应用程序属性（application-{profile}.properties 和 YAML 变体）
- 打包 jar 之外的应用程序属性（application.properties 和 YAML 变体）。
- 打包在您的 jar 中的应用程序属性（application.properties 和 YAML 变体）。
- @Configuration 上的@PropertySource 注释类。
默认属性（使用 SpringApplication.setDefaultProperties 指定）。
你可以找到官方文档here。
在您的情况下，有一个 OS 环境变量 SPRING_DATASOURCE_URL（编号 4），它会覆盖打包在您的 jar spring.datasource.url（编号 9）中的应用程序属性。
所以下次用IDEA运行配置设置环境变量，这样环境变量只对你运行ning的项目起作用。

Spring Boot 使用非常特殊的 PropertySource 顺序，该顺序旨在允许合理地覆盖值，按以下顺序考虑属性：
- 命令行参数。
- 来自 java 的 JNDI 属性：comp/env.
- Java 系统属性 (System.getProperties())。
- OS 环境变量。
- 只具有随机属性的 RandomValuePropertySource。*。
- 打包的 jar 文件之外的特定于配置文件的应用程序属性（application-{profile}.properties 和 YAML 变体）
- 打包在您的 jar 中的特定于配置文件的应用程序属性（application-{profile}.properties 和 YAML 变体）
- 打包 jar 之外的应用程序属性（application.properties 和 YAML 变体）。
- 打包在您的 jar 中的应用程序属性（application.properties 和 YAML 变体）。
- @Configuration 上的@PropertySource 注释类。 默认属性（使用 SpringApplication.setDefaultProperties 指定）。
你可以找到官方文档here。
在您的情况下，有一个 OS 环境变量 SPRING_DATASOURCE_URL（编号 4），它会覆盖打包在您的 jar spring.datasource.url（编号 9）中的应用程序属性。
所以下次用IDEA运行配置设置环境变量，这样环境变量只对你运行ning的项目起作用。
