java-从Spring Boot应用程序连接到本地MySQL数据库时出错

(java - Error connecting to local MySQL database from spring boot application)

发布于 2020-11-30 20:13:19

我正在使用Intellij IDEA，在Spring Boot应用程序上工作并尝试连接到在docker中运行的mysql数据库。我在application.properties文件中设置了连接属性。问题是它似乎在启动时没有使用这些属性。如下所示，它正在尝试连接到我在项目中任何地方都未引用的另一个数据库。看来jdbc字符串是从其他地方拾取的，但我不确定这可能在哪里。我已经使缓存无效并重新启动，并且还删除了.gradle内的caches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。有人遇到过这个问题吗？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。

application.properties

#MySQL connection properties
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.username=${SPRING_DATASOURCE_USERNAME}
spring.datasource.password=${SPRING_DATASOURCE_PASSWORD}
spring.datasource.url=jdbc:mysql://localhost:3306/myDatabase?serverTimezone=UTC

# Hibernate SQL dialect
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect

server.port=9090
spring.jpa.show-sql=true

Spring Boot使用一个非常特殊的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：

  1. 命令行参数。
  2. 来自java：comp / env的JNDI属性。
  3. Java系统属性（System.getProperties（））。
  4. 操作系统环境变量。
  5. 一个RandomValuePropertySource，仅具有random。*属性。
  6. 打包的jar之外的特定于配置文件的应用程序属性（application- {profile} .properties和YAML变体）
  7. 打包在jar中的特定于配置文件的应用程序属性（application- {profile} .properties和YAML变体）
  8. 打包的jar之外的应用程序属性（application.properties和YAML变体）。
  9. 打包在jar中的应用程序属性（application.properties和YAML变体）。
  10. @Configuration类上的@PropertySource批注。默认属性（使用SpringApplication.setDefaultProperties指定）。

你可以在此处找到官方文档。

在你的情况下，有一个OS环境变量SPRING_DATASOURCE_URL（数字4）会覆盖打包在jar中的应用程序属性spring.datasource.url（数字9）。

因此，下次使用IDEA运行配置设置环境变量，以便环境变量仅在你正在运行的项目上起作用。
