我正在尝试测试Keycloak REST API。安装了版本2.1.0.Final。我可以通过SSL浏览器访问管理员没有问题。
我使用上面的代码：

Keycloak keycloakClient = KeycloakBuilder.builder()
.serverUrl("https://keycloak.intra.rps.com.br/auth")
.realm("testrealm")
.username("development")
.password("development")
.clientId("admin-cli")
.resteasyClient(new ResteasyClientBuilder().connectionPoolSize(10).build())
.build();
List<RealmRepresentation> rr = keycloakClient.realms().findAll();

并得到了错误：

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

我添加了上面的依赖项，但没有解决我的问题：

<dependency>
            <groupId>org.jboss.resteasy</groupId>
            <artifactId>resteasy-client</artifactId>
            <version>3.0.19.Final</version>
    </dependency>
    <dependency>
            <groupId>org.jboss.resteasy</groupId>
            <artifactId>resteasy-jackson-provider</artifactId>
            <version>3.0.19.Final</version>
    </dependency>

有线索吗？

我使用依赖关系解决了此问题

<dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-jackson2-provider</artifactId>
        <version>3.1.0.Final</version>
    </dependency>

我解决了！！你必须添加org.jboss.resteasy.plugins.providers.Jackson. reteasyjacksonProvider到META-INF/services/javax.ws.rs.ext.Providers文件中，然后运行你的可执行文件jar。

或者，如果您使用代理创建客户端，则最好在以下操作之前初始化提供程序工厂：

ResteasyProviderFactory instance=ResteasyProviderFactory.getInstance();
    RegisterBuiltin.register(instance);
    instance.registerProvider(ResteasyJackson2Provider.class);

添加Dmitry pointed out here for me会导致以下警告：

WARN: RESTEASY002155: Provider class org.jboss.resteasy.plugins.providers.jackson.ResteasyJackson2Provider is already registered.  2nd registration is being ignored.

as Bacon said提供程序可能通过简单地添加依赖项来自动注册：

<dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-jackson2-provider</artifactId>
        <version>${resteasy.version}</version>
    </dependency>

MatteoM指出，我遇到了这个问题。我用maven shade插件和transformes标签解决了这个问题。也许它能帮助一些人。

在wildfly 11 / Keycloak上下文中，下面的代码使其与RestEasyClientBuilder一起工作。

ResteasyClientBuilder builder = new ResteasyClientBuilder();
ResteasyProviderFactory providerFactory = ResteasyProviderFactory.getInstance();
builder.providerFactory(providerFactory);

请仔细检查您的Resteasy版本中ResteasyProviderFactory是否默认为true。如果不是，请手动设置内置：

ResteasyProviderFactory.setRegisterBuiltinByDefault(true);
// or if ResteasyProviderFactory was already instantiated
RegisterBuiltin.register(providerFactory);

在我的例子中，我将根本问题追溯到我切换到CompletableFuture的事实。
使用的客户端版本可能是过时的或什么的，当它在eclipse中工作时，从外部可执行文件中，它会崩溃并出现此错误。
我可能会发布一个修复程序，但它要么是：请更新库或停止在此库上使用CompletableFuture。

在创建目标/客户端时，您是否注册了@Provider的示例？我发现您没有。
在我的例子中，我从Resteasy 3转移到了Resteasy 4，并且接收到了text/plain类型的内容。在Resteasy-jaxrs 3中，我使用了ResteasyJackson2Provider，它实现了MessageBodyReader和MessageBodyWriter，并且成功了。现在，在Resteasy 4中，这个同名类的isReadable()只接受null的Content-Type或包含json。当我收到text/plain时，它不再工作。
对于阅读纯文本，我建议使用StringTextStar。这是Resteasy 4.7.5中的一个新类，看起来很有效。读取inputstream并以字符串形式写入，这正是我所需要的。检查它的impl。

ResteasyClient client = new ResteasyClient().uri(...)
                          .register(new ResteasyJackson2Provider()) // now only for writing
                          .register(new StringTextStar());         // use this for reading

我觉得你很好。
