Question

我试图将KeyCloak Admin Client与Spring Boot集成

但是当我尝试创建一个新帐户时会抛出异常：

Caused by: javax.ws.rs.ProcessingException: RESTEASY003145: Unable to find a MessageBodyReader of content-type application/json and type class org.keycloak.representations.AccessTokenResponse

所以我试着像这样明确地为KeyCloak注册Jackson Provider：

            KeycloakBuilder
            .builder()
            .serverUrl(SERVER_URL)
            .realm(REALM)
            .username(USERNAME)
            .password(PASSWORD)
            .clientId(CLIENT_ID)
            .resteasyClient(new ResteasyClientBuilder()
                  .providerFactory(factory.register(ResteasyJackson2Provider.class))
                    .connectionPoolSize(10)
                    .build())
            .build();

但我无法导入ResteasyJackson2Provider.class

的pom.xml

<dependency>
    <groupId>org.keycloak</groupId>
    <artifactId>keycloak-spring-security-adapter</artifactId>
    <version>3.1.0.Final</version>
</dependency>
<dependency>
    <groupId>org.keycloak</groupId>
    <artifactId>keycloak-admin-client</artifactId>
    <version>3.1.0.Final</version>
</dependency>
<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jaxrs</artifactId>
    <version>3.1.3.Final</version>

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-client</artifactId>
    <version>3.1.3.Final</version>
</dependency>
<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jackson2-provider</artifactId>
    <version>3.1.3.Final</version>
</dependency>

顺便说一下，如果我使用resteasy-jackson-provider，我就会遇到这个例外：

javax.ws.rs.client.ResponseProcessingException: javax.ws.rs.ProcessingException: org.codehaus.jackson.map.exc.UnrecognizedPropertyException: Unrecognized field "access_token" (Class org.keycloak.representations.AccessTokenResponse), not marked as ignorable
 at [Source: org.jboss.resteasy.client.jaxrs.internal.ClientResponse$InputStreamWrapper@7cc842b0; line: 1, column: 18] (through reference chain: org.keycloak.representations.AccessTokenResponse["access_token"])

过了一会儿，我找到了解决这个问题的方法：

首先，我使用独立项目（空maven项目）对其进行了测试，由于resteasy-jackson-provider，问题仍然存在。它应该是resteasy-jackson2-provider（注意它的重新 - jackson2 - 提供者）

目前，我知道这个问题不知何故来自Spring Boot，RESTeasy。最后，我想出了这个工作 pom.xml ：

    <dependency>
        <groupId>org.keycloak</groupId>
        <artifactId>keycloak-admin-client</artifactId>
        <version>3.1.0.Final</version>
    </dependency>
    <dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-client</artifactId>
        <version>3.1.3.Final</version>
    </dependency>
    <dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-jackson2-provider</artifactId>
        <version>3.1.3.Final</version>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-core</artifactId>
        <version>2.8.8</version>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.8.8</version>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-annotations</artifactId>
        <version>2.8.8</version>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.jaxrs</groupId>
        <artifactId>jackson-jaxrs-json-provider</artifactId>
        <version>2.8.8</version>
    </dependency>

还有一点需要注意的是，您应该在Keycloak中使用 admin-cli 客户端，因为默认情况下， 启用Direct Access Grants

顺便说一句，这是Java配置：

KeycloakBuilder .builder() .serverUrl("localhost:8080/auth") .realm("master") .username("YOUR_USERNAME") .password("YOUR_PASSWORD") .clientId("admin-cli") .build();
