属性中的java Spring引导和KeyClope配置会引发NullPointerException，然后引发500个状态代码

Question

我目前正在做一个项目，我必须处理Spring Boot和KeyClope。 我想要应用程序中的配置。弹簧的特性。 以下是我的配置文件的一部分：

keycloak.enabled = true
keycloak.auth-server-url=${SSO_URL:http://MYIP:8082/auth/}
keycloak.realm=${SSO_REALM:approfox-dev}
keycloak.resource=${SSO_CLIENT:approfox-dev-login}
keycloak.ssl-required=none
keycloak.public-client=true
keycloak.principal-attribute=preferred_username

但当我试图访问任何API端点时，我得到了一个500内部服务器错误，只有一个NullPointerException。我不知道从哪里或者为什么会发生这种异常。似乎应用程序属性文件不是由KeyClock加载的，因为当我使用KeyClock时。json和加载它的方法是有效的

@Configuration
@EnableWebSecurity
@KeycloakConfiguration
@ComponentScan(basePackageClasses = KeycloakSecurityComponents.class)
@ConditionalOnProperty(
    value = "keycloak.enabled",
    havingValue = "true",
    matchIfMissing = false
)
class SecurityConfig extends KeycloakWebSecurityConfigurerAdapter {

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) {
        SimpleAuthorityMapper grantedAuthorityMapper = new SimpleAuthorityMapper();
        grantedAuthorityMapper.setPrefix("ROLE_");

        KeycloakAuthenticationProvider keycloakAuthenticationProvider = keycloakAuthenticationProvider();
        keycloakAuthenticationProvider.setGrantedAuthoritiesMapper(grantedAuthorityMapper);
        auth.authenticationProvider(keycloakAuthenticationProvider);
    }
    @Bean
    @Override
    @ConditionalOnMissingBean(HttpSessionManager.class)
    protected HttpSessionManager httpSessionManager() {
        return new HttpSessionManager();
    }

    // Keycloak Spring Boot resolver not working

    public KeycloakSpringBootConfigResolver KeycloakConfigResolver() {
        return new KeycloakSpringBootConfigResolver();
    }

    @Bean
    @Override
    protected SessionAuthenticationStrategy sessionAuthenticationStrategy() {
        return new RegisterSessionAuthenticationStrategy(
                new SessionRegistryImpl());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        super.configure(http);
        http.csrf()
                .disable()
                .cors()
                .and()
                .authorizeRequests()
                .antMatchers("/exemple1")
                .hasRole("student")
                .antMatchers("/exemple2")
                .hasRole("admin")
                .anyRequest()
                .permitAll();
    }



    // keycloak.json working...
    /**

    /*@Bean

                if (keycloakDeployment != null) {
                    return keycloakDeployment;
                }

                String path = "/keycloak.json";
                InputStream configInputStream = getClass().getResourceAsStream(path);

                if (configInputStream == null) {
                    throw new RuntimeException("Could not load Keycloak deployment info: " + path);
                } else {
                    keycloakDeployment = KeycloakDeploymentBuilder.build(configInputStream);
                }

                return keycloakDeployment;
            }
        };
    }*/
}

我已经在网上搜索过了，我找不到关于那个问题的任何信息
