【问题讨论】：

  • "... Caused by: java.lang.IllegalArgumentException: Null value for 'password' ..."
  • 关于这是哪里的任何建议？我正在为登录和注册页面编写后端代码，但我的代码中没有看到任何空值。
  • 您应该检查application.properties/application.yaml文件中的数据源配置或提供数据库设置的任何位置。
  • 我建议阅读有关该主题的教程，例如this official spring tutorial on Accessing data with MySQL.
  • 在application.yaml找到了，谢谢你的帮助！

标签： java spring spring-boot hibernate


【解决方案1】：

我有同样的错误。在 application.properties 中提供用户名和密码为我解决了这个问题。

【讨论】：

    【解决方案2】：

    根据活动的配置文件，确保您的测试属性具有以下内容：

    spring.datasource.url=jdbc:postgresql://localhost:5432/your_database
spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.username= database_user
spring.datasource.password= database_password

    如果您使用任何其他数据库，请确保替换 postgre。

    【讨论】：

      【解决方案3】：

      其实我也有同样的问题，我的解决办法是去postgresqlenter image description here

      然后输入如上图所示的用户名，然后输入密码 0000 enter image description here

      解决方案如下面的截图所示： enter image description here
