public enum GrantType extends Enum<GrantType>
OAuth2 Grant Type Enum OAuth2 授权类型枚举

Defines the supported OAuth2 grant types.

定义支持的 OAuth2 授权类型。

Supported Grant Types | 支持的授权类型:

  • AUTHORIZATION_CODE - Web applications - Web 应用
  • CLIENT_CREDENTIALS - Server-to-server - 服务器间通信
  • DEVICE_CODE - CLI/IoT devices - CLI/IoT 设备
  • REFRESH_TOKEN - Token refresh - Token 刷新

Features | 主要功能:

  • OAuth2 grant type enumeration - OAuth2授权类型枚举
  • Supports authorization_code, client_credentials, device_code, refresh_token - 支持授权码、客户端凭证、设备码、刷新令牌

Usage Examples | 使用示例:

// Select grant type for OAuth2 flow
// 为OAuth2流程选择授权类型
GrantType type = GrantType.AUTHORIZATION_CODE;
String value = type.getValue();

Security | 安全性:

  • Thread-safe: Yes (immutable enum) - 线程安全: 是（不可变枚举）
  • Null-safe: Yes - 空值安全: 是
