泽西岛客户端 javax.ws.rs.client.Client 未找到

Question

我有一个球衣客户。我在客户端类中有以下导入

import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.Entity;
import javax.ws.rs.client.Invocation;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

当我编译应用程序时，我得到

./src/com/uciext/ws/class2/client/StudentClient.java:3: error: package javax.ws.rs.client does not exist
import javax.ws.rs.client.Client;
                         ^

如何解决这个问题

这是c.sh。我使用球衣2.2.7。我下载了 jersey 2.2.7 并将其复制到我的 lib 文件夹中。难道我的jar版本不对吗？

Answer 1

参加聚会有点晚了，但会回答以防其他人遇到这个问题。你问的最后一个问题是关键。是的，您可能使用了错误版本的罐子。

我正在开发一个遗留系统，并且遇到了与您相同的问题。结果我不得不使用 jakarta.ws.rs... 而不是 javax.ws.rs... 与我拥有的 jar 版本。要使用 javax.ws.rs...，我必须使用 2.25.x 版本（因为它实现了 JAX-RS 2.0 API）及更低版本。 在这里

查找版本

这是 Java EE 从 Oracle 转移到 Eclipse 基金会的一部分。

Answer 2

您是否包含了依赖项来获取此包的实现？
如果您使用 Maven this 帖子，请提供详细信息。
对于库版本，请从here下载库并按照以下tutorial添加所需的jar。虽然 Client 类在 jaxrs-ri pi jar 中可用。

Answer 3

您想要获取 这个 zip 文件，并确保

jaxrs-ri/api/jakarta.ws.rs-api-2.1.6.jar

在您的类路径中。
