你给的代码中，oauth2的Datasource的依赖是什么

在代码中，oauth2的Datasource的依赖是JDBC依赖，需要在pom.xml文件中添加以下依赖：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
<dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
    <scope>runtime</scope>
</dependency>

其中，spring-boot-starter-jdbc是Spring Boot中的JDBC starter，h2是一个内存数据库，用于测试和开发环境。在生产环境中，您需要将其替换为其他数据库的驱动程序和依赖项。

Oauth2进行认证授权代码示例

以下是一个基于Spring Security OAuth2的认证授权代码示例：

1. 添加Maven依赖

<dependency>
    <groupId>org.springframework.security.oauth</groupId>
    <artifactId>spring-security-oauth2</artifactId>
    <version>2.4.0.RELEASE</version>
</dependency>

2. 配置OAuth2服务器

@Configuration
@EnableAuthorizationServer
public class OAuth2AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private AuthenticationManager authenticationManager;

    @Autowired
    private DataSource dataSource;

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.jdbc(dataSource);
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.authenticationManager(authenticationManager);
    }
}

3. 配置资源服务器

@Configuration
@EnableResourceServer
public class OAuth2ResourceServerConfig extends ResourceServerConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().anyRequest().authenticated();
    }
}

4. 配置Spring Security

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().antMatchers("/oauth/**").permitAll().anyRequest().authenticated().and().csrf().disable();
    }

    @Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
}

5. 配置数据源

@Configuration
public class DataSourceConfig {

    @Bean
    @ConfigurationProperties(prefix = "spring.datasource")
    public DataSource dataSource() {
        return DataSourceBuilder.create().build();
    }
}

6. 配置应用属性

spring.datasource.url=jdbc:mysql://localhost:3306/oauth2
spring.datasource.username=root
spring.datasource.password=root

security.oauth2.client.client-id=client
security.oauth2.client.client-secret=secret
security.oauth2.client.access-token-validity-seconds=3600
security.oauth2.client.authorized-grant-types=authorization_code,refresh_token,password,client_credentials
security.oauth2.client.scope=read,write
security.oauth2.resource.id=resource

security.user.name=user
security.user.password=password
security.user.roles=USER

以上代码仅供参考，具体实现需要根据实际场景进行调整。

oauth2单点登录代码

OAuth 2.0 单点登录的实现需要依赖于一个认证服务器和多个客户端应用程序。以下是一个使用 Spring Security OAuth2 实现单点登录的示例代码：

1. 添加依赖

<dependency>
    <groupId>org.springframework.security.oauth</groupId>
    <artifactId>spring-security-oauth2</artifactId>
    <version>2.3.4.RELEASE</version>
</dependency>

2. 配置认证服务器

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private AuthenticationManager authenticationManager;

    @Autowired
    private UserDetailsService userDetailsService;

    @Autowired
    private DataSource dataSource;

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.jdbc(dataSource);
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints.authenticationManager(authenticationManager)
                .userDetailsService(userDetailsService);
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security.checkTokenAccess("isAuthenticated()");
    }
}

3. 配置客户端应用程序

@Configuration
@EnableOAuth2Sso
public class ClientApplicationConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.antMatcher("/**")
                .authorizeRequests()
                .antMatchers("/", "/login**", "/error**")
                .permitAll()
                .anyRequest()
                .authenticated()
                .and()
                .logout()
                .logoutSuccessUrl("/")
                .permitAll()
                .and()
                .csrf()
                .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());
    }
}

4. 配置资源服务器

@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .antMatchers("/api/**")
                .authenticated()
                .and()
                .csrf()
                .disable()
                .sessionManagement()
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }
}

以上代码仅提供了一个简单的示例，实际实现中还需要根据具体情况进行配置和改进。
