我正在使用keycloak测试一个web应用spring boot的安全性，我添加了所有必要的依赖项，但我在撕裂应用程序时遇到了一个问题。

我使用: spring boot 2.2.0.M3 Java 11

我包括: keycloak-spring-boot-starter和keycloak-adapter-bom

这是我的pom.xml：

spring-boot中有一个bug，are服务器定制器会被调用两次。因为错误密钥罩被初始化了两次。在spring-boot 2.2.0.M5中解决了这个问题。所以升级spring-boot将会解决这个问题。

请参阅https://github.com/spring-projects/spring-boot/issues/17264

可以通过添加以下内容来排除KeycloakAutoConfiguration类

代码语言：javascript
复制
@SpringBootApplication( exclude = { KeycloakAutoConfiguration.class } )

注解到您的主应用程序类。
