带Spring Boot 2的Keycloak 4.0.0 Beta 2

2023-03-14

当我尝试使用key cloak-spring-boot-starter(key cloak-adapter-BOM)时。我得到一个错误。我错过了什么吗？

我的keyclock运行正常。如果我试图从pom文件中删除keyclock依赖项，Spring Boot应用程序也可以正常工作。

对于任何在 2019 年查看这个问题的人：这对我有用

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.4.RELEASE</version>
        <relativePath/>
        <!-- lookup parent from repository -->
    </parent>


        <dependency>
            <groupId>org.keycloak</groupId>
            <artifactId>keycloak-spring-boot-2-starter</artifactId>
            <version>4.0.0.Final</version>
        </dependency>

如果您使用的是Maven，只需添加keycloak-spring-boot-2-starter依赖项：

<!-- https://mvnrepository.com/artifact/org.keycloak/keycloak-spring-boot-2-starter -->
<dependency>
    <groupId>org.keycloak</groupId>
    <artifactId>keycloak-spring-boot-2-starter</artifactId>
    <version>4.0.0.Final</version>
</dependency>

我也有同样的问题。只需确保包含Spring防尘套2启动器，不要直接使用适配器。

compile 'org.keycloak:keycloak-spring-boot-2-starter:4.0.0.Beta2'
