java - Jhipster - MySQL java.sql.SQLException : Access denied for user 'root' @'localhost' (using password: NO) 错误

Question

我正在尝试通过 JHipster 创建一个项目并将其部署到 Openshif。 一切看起来都很正常，但是当运行 mvn spring-boot:run 或从 IDE 运行时，没有与 MySQL 数据库的连接。

错误是:

我在 IntelliJ IDE 中配置了 SQL 连接，所以问题不存在。 我还生成了两个具有 1-1 关系的实体(根据 jhipster 的建议，realtion 的所有者是其次生成的)。

当我将一个项目部署到 Openshift 时，它给了我起始页面等，但是在应用程序的“实体”菜单中 - 根本没有显示任何实体，菜单是空白的。所以，我假设问题出在项目本身的某个地方或者可能是它的偏好。有什么想法可以解决此错误吗？

Answer 1

将密码设置为 '' 不是一种安全的做法。 JHipster 生成的应用程序在几个地方需要 mysql 密码。如果设置正确，应用程序可以使用密码连接到数据库。

1. liquibase 插件的 pom.xml (Maven) 或 liquibase.gradle (Gradle)
2. 在 src/main/resources/config 文件夹中的 application-dev.yml 和 application-prod.yml 中。

希望对您有所帮助。
