我正在使用keycloak测试Web应用程序春季启动的安全性,添加了所有必需的依赖项,但是在对应用程序进行扩展时遇到了问题。
我使用: 弹簧靴2.2.0.M3 Java 11
我包括: keycloak-spring-boot-starter和keycloak-adapter-bom
这是我的pom.xml:

您可以通过添加
来排除KeycloakAutoConfiguration
类
@SpringBootApplication( exclude = { KeycloakAutoConfiguration.class } )
对主要应用程序类的注释。

spring-boot中有一个错误,即两次调用Web服务器定制程序。因为该错误keycloak初始化了两次。在spring-boot 2.2.0.M5中解决了。因此,升级spring-boot将解决此问题。
