无法定义以KeyClope开头的属性。如果keydape-spring-boot-starter-jar观察到jar不知道的keydape属性，它将无法加载属性。如果我们添加前缀，问题就会得到解决” sso “对于属性，是否有一种方法可以避免此错误，即使保留keydape前缀。

keycloak.admin.username=
keycloak.admin.password=

sso.keycloak.admin.username=
sso.keycloak.admin.password=

这就是我们看到的错误 Spring Boot 2.5.0 and Keycloak 13.0.0 ```

此错误是在SpringBoot2.5.0附带的SpringSecurity版本5.5.0中引入的。之所以会发生这种情况，是因为Key斗篷连续添加了两个过滤器，如下所示：

@Override
protected void configure(HttpSecurity http) throws Exception {
        http
                ...
                .addFilterAfter(keycloakSecurityContextRequestFilter(), SecurityContextHolderAwareRequestFilter.class)
                .addFilterAfter(keycloakAuthenticatedActionsRequestFilter(), KeycloakSecurityContextRequestFilter.class)
                ...
}

现在有一个bug，自定义过滤器顺序没有被持久化，从而导致 NullPointerException 尝试相对于最近添加的另一个自定义筛选器添加筛选器时。
我建议您现在就使用较低版本的spring boot，比如2.4.x，直到github中的问题得到解决。

从KeyClope代码来看，他们似乎只将属性硬连接到了特定的属性。
从keydepospringbootproperties
/这是一个虚拟属性，以避免在使用spring cloud时属性keydove.config.resolver出现重新绑定问题-请参阅keydove-2977/
从他们的代码来看，似乎我们可以利用一种变通方法，他们必须包含额外的属性。但要做到这一点，我们必须在其中添加'config'。

keycloak.config.admin.username=asd
keycloak.config.admin.password=sss
