原因：java.lang.ClassNotFoundException：找不到 jakarta.ws.rs.client.ClientBuilder 的提供程序

Question

我正在将我的项目从 Java EE 7 迁移到 Jakarta EE 10.0.0，并更改了所有与 jakarta 相关的 javax 引用。

我没有任何编译问题，但在运行时出现以下错误。

原因：java.lang.ClassNotFoundException：找不到 jakarta.ws.rs.client.ClientBuilder 的提供程序。

以下是我在项目中使用的依赖项。我添加了 jersey-client 和 jersey-media-json-jackson 来修复 ClientBuilder 问题。

我已经实现了我的 ClientBuilder，如下所示

CLIENT = ClientBuilder.newBuilder().register(JacksonFeature.class).build();

Answer 1

我能够通过添加以下依赖项并将客户端生成器实现更改为

来解决该问题

CLIENT = JerseyClientBuilder.newClient();

        <dependency>
            <groupId>org.glassfish.jersey.core</groupId>
            <artifactId>jersey-client</artifactId>
            <version>3.1.5</version>
        </dependency>
        <dependency>
            <groupId>org.glassfish.jersey.inject</groupId>
            <artifactId>jersey-hk2</artifactId>
            <version>3.1.5</version>
        </dependency>
        <dependency>
            <groupId>org.glassfish.jersey.media</groupId>
            <artifactId>jersey-media-json-binding</artifactId>
