CommandLineRunner 不会为用户添加角色
CommandLineRunner won't add roles to users
我在 Spring 引导安全上关注 tutorial，但我被卡住了。目前我正在设置一个 CommandLineRunner，它会做 3 件事：
- 创建角色
- 创建用户
- 为用户添加角色
运行 代码创建一个 table 和创建的角色，并为创建的用户创建一个 table，但是向用户添加角色最终会出错。我检查了几次代码，但没有发现错误。

方法 userRepo.findByUsername 需要返回一个对象。
用户 user = userRepo.findByUsername(用户名)
但是您有超过 1 个用户使用相同的用户名。
每次您 运行 应用程序都会在数据库中再次添加相同的用户
- 您可以在再次将用户添加到数据库之前检查用户是否存在。
- 将用户名设为主键。
我在 Spring 引导安全上关注 tutorial，但我被卡住了。目前我正在设置一个 CommandLineRunner，它会做 3 件事：
- 创建角色
- 创建用户
- 为用户添加角色 运行 代码创建一个 table 和创建的角色，并为创建的用户创建一个 table，但是向用户添加角色最终会出错。我检查了几次代码，但没有发现错误。
