Red Hat Single Sign-On整合spirngboot之Spring Boot adapter

在Red Hat Single Sign-On (SSO) 中整合 Spring Boot 应用通常涉及到创建一个适配器。以下是一个简化的示例，展示了如何创建一个适配器来与 Spring Boot 应用程序进行整合。

1. 在 Spring Boot 应用中添加必要的依赖：

<!-- 添加 Red Hat SSO 客户端依赖 -->
<dependency>
    <groupId>org.keycloak</groupId>
    <artifactId>keycloak-spring-boot-starter</artifactId>
    <version>16.0.1</version>
</dependency>

2. 在 application.properties 或 application.yml 中配置 Keycloak：

# Keycloak 服务器的配置
keycloak.auth-server-url=http://sso-server/auth
keycloak.realm=your-realm
keycloak.resource=your-client
keycloak.public-client=true
# 如果需要的话，可以配置角色的映射策略
keycloak.securityConstraints[0].authRoles[0]=your-role

3. 在 Spring Boot 应用中配置安全配置：

import org.keycloak.adapters.springboot.KeycloakSpringBootConfigResolver;
import org.keycloak.adapters.springsecurity.config.KeycloakSecurityConfigurerAdapter;
import org.springframework.boot.web.servlet.ServletContextInitializer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Profile;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
 
@KeycloakSecurityConstraints(securityConstraints = {
    @SecurityConstraint(authRoles = { "your-role" })
})
public class SecurityConfig extends KeycloakSecurityConfigurerAdapter {
 
    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) {
        auth.parentAuthenticationManager(authenticationManager());
    }
 
    @Bean
    public ServletContextInitializer keycloakServletContextInitializer() {
        return new KeycloakServletContextInitializer(new AdapterDeploymentContext() {
            @Override
            public KeycloakDeployment resolveDeployment(HttpFacade.Request request) {
                return KeycloakDeploymentBuilder.build
