对于最新的稳定版本，请使用 Spring Authorization Server 1.4.2！spring-doc.cadn.net.cn

作方法：使用 JPA 实现核心服务

本指南介绍如何使用 JPA 实现 Spring Authorization Server 的核心服务。本指南的目的是为自行实施这些服务提供一个起点，以便您可以进行修改以满足您的需要。spring-doc.cadn.net.cn

定义数据模型

本指南为数据模型提供了一个起点，并使用了最简单的结构和数据类型。为了提出初始架构，我们首先回顾核心服务使用的域对象。spring-doc.cadn.net.cn

除了 token、state、metadata、settings 和 claims 值之外，我们对所有列使用 JPA 默认列长度 255。实际上，您可能需要自定义您使用的列的长度甚至类型。建议您在部署到生产环境之前进行试验和测试。

客户端架构

这RegisteredClientdomain 对象包含一些多值字段和一些需要存储任意键值数据的 settings 字段。下面的清单显示了client图式。spring-doc.cadn.net.cn

客户端架构

CREATE TABLE client (
    id varchar(255) NOT NULL,
    clientId varchar(255) NOT NULL,
    clientIdIssuedAt timestamp DEFAULT CURRENT_TIMESTAMP NOT NULL,
    clientSecret varchar(255) DEFAULT NULL,
    clientSecretExpiresAt timestamp DEFAULT NULL,
    clientName varchar(255) NOT NULL,
    clientAuthenticationMethods varchar(1000) NOT NULL,
    authorizationGrantTypes varchar(1000) NOT NULL,
    redirectUris varchar(1000) DEFAULT NULL,
    postLogoutRedirectUris varchar(1000) DEFAULT NULL,
    scopes varchar(1000) NOT NULL,
    clientSettings varchar(2000) NOT NULL,
    tokenSettings varchar(2000) NOT NULL,
    PRIMARY KEY (id)
);

授权架构

这OAuth2Authorizationdomain 对象更复杂，包含多个多值字段以及许多任意长的令牌值、元数据、设置和声明值。内置的 JDBC 实现利用了扁平化结构，该结构更注重性能而不是规范化，我们在这里也采用了这一点。spring-doc.cadn.net.cn

很难找到一种在所有情况下都适用于所有数据库供应商的扁平化数据库架构。您可能需要根据需要规范化或大量更改以下架构。

下面的清单显示了authorization图式。spring-doc.cadn.net.cn

授权架构

CREATE TABLE authorization (
    id varchar(255) NOT NULL,
    registeredClientId varchar(255) NOT NULL,
    principalName varchar(255) NOT NULL,
    authorizationGrantType varchar(255) NOT NULL,
    authorizedScopes varchar(1000) DEFAULT NULL,
    attributes varchar(4000) DEFAULT NULL,
    state varchar(500) DEFAULT NULL,
    authorizationCodeValue varchar(4000) DEFAULT NULL,
    authorizationCodeIssuedAt timestamp DEFAULT NULL,
    authorizationCodeExpiresAt timestamp DEFAULT NULL,
    authorizationCodeMetadata varchar(2000) DEFAULT NULL,
    accessTokenValue varchar(4000) DEFAULT NULL,
    accessTokenIssuedAt timestamp DEFAULT NULL,
    accessTokenExpiresAt timestamp DEFAULT NULL,
    accessTokenMetadata varchar(2000) DEFAULT NULL,
    accessTokenType varchar(255) DEFAULT NULL,
    accessTokenScopes varchar(1000) DEFAULT NULL,
    refreshTokenValue varchar(4000) DEFAULT NULL,
    refreshTokenIssuedAt timestamp DEFAULT NULL,
    refreshTokenExpiresAt timestamp DEFAULT NULL,
    refreshTokenMetadata varchar(2000) DEFAULT NULL,
    oidcIdTokenValue varchar(4000) DEFAULT NULL,
    oidcIdTokenIssuedAt timestamp DEFAULT NULL,
    oidcIdTokenExpiresAt timestamp DEFAULT NULL,
    oidcIdTokenMetadata varchar(2000) DEFAULT NULL,
    oidcIdTokenClaims varchar(2000) DEFAULT NULL,
    userCodeValue varchar(4000) DEFAULT NULL,
    userCodeIssuedAt timestamp DEFAULT NULL,
    userCodeExpiresAt timestamp DEFAULT NULL,
    userCodeMetadata varchar(2000) DEFAULT NULL,
    deviceCodeValue varchar(4000) DEFAULT NULL,
    deviceCodeIssuedAt timestamp DEFAULT NULL,
    deviceCodeExpiresAt timestamp DEFAULT NULL,
    deviceCodeMetadata varchar(2000) DEFAULT NULL,
    PRIMARY KEY (id)
);

这OAuth2AuthorizationConsentdomain 对象是最容易建模的，除了一个组合键之外，只包含一个多值字段。下面的清单显示了authorizationconsent图式。spring-doc.cadn.net.cn

授权同意架构

CREATE TABLE authorizationConsent (
    registeredClientId varchar(255) NOT NULL,
    principalName varchar(255) NOT NULL,
    authorities varchar(1000) NOT NULL,
    PRIMARY KEY (registeredClientId, principalName)
);

创建 JPA 实体

前面的架构示例为我们需要创建的实体的结构提供了参考。spring-doc.cadn.net.cn

以下实体进行了最低限度的注释，只是示例。它们允许动态创建架构，因此不需要手动执行上述 sql 脚本。

Create Spring Data repositories


By closely examining the interfaces of each core service and reviewing the Jdbc implementations, we can derive a minimal set of queries needed for supporting a JPA version of each interface.spring-doc.cadn.net.cn




Client Repositoryspring-doc.cadn.net.cn

Authorization Repository

The following listing shows the AuthorizationRepository, which is able to find an Authorization by the id field as well as the state, authorizationCodeValue, accessTokenValue, refreshTokenValue, userCodeValue and deviceCodeValue token fields.
It also allows querying a combination of token fields.spring-doc.cadn.net.cn

Authorization Consent Repository

The following listing shows the AuthorizationConsentRepository, which is able to find and delete an AuthorizationConsent by the registeredClientId and principalName fields that form a composite primary key.spring-doc.cadn.net.cn


Authorization Consent Repository

import java.util.Optional;

import sample.jpa.entity.authorizationconsent.AuthorizationConsent;

	Optional<AuthorizationConsent> findByRegisteredClientIdAndPrincipalName(String registeredClientId, String principalName);
	void deleteByRegisteredClientIdAndPrincipalName(String registeredClientId, String principalName);
}







Implement core services


With the above entities and repositories, we can begin implementing the core services.
By reviewing the Jdbc implementations, we can derive a minimal set of internal utilities for converting to and from string values for enumerations and reading and writing JSON data for attributes, settings, metadata and claims fields.spring-doc.cadn.net.cn








Keep in mind that writing JSON data to text columns with a fixed length has proven problematic with the Jdbc implementations.
While these examples continue to do so, you may need to split these fields out into a separate table or data store that supports arbitrarily long data values.
