java - 带有 CDI Weld 4 而非 HK2 的 Jersey 3

Question

我有一个小型 JAX-RS (Jersey 3.0.1) API 在独立的 Jetty 11 中运行，但想使用 Weld 4.0.0 而不是 HK2。 Jetty 正确引导 Weld 上下文(Jetty 模块 ci-decorate 已按照 Weld documentation 中的说明进行安装)

WELD-ENV-001212: Jetty CdiDecoratingListener support detected, CDI injection will be available in Listeners, Servlets and Filters.

在调用 API 端点时会发生异常:

WARNING: The following warnings have been detected: WARNING: Unknown HK2 failure detected:

我在 pom.xml 中的依赖项如下所示:

        <dependency>
            <groupId>org.jboss.weld.servlet</groupId>
            <artifactId>weld-servlet-core</artifactId>
            <version>4.0.0.Final</version>
        </dependency>
        <dependency>

            <artifactId>jakarta.servlet-api</artifactId>

        </dependency>

        </dependency>
        <dependency>
            <groupId>org.glassfish.jersey.ext.cdi</groupId>
            <artifactId>jersey-weld2-se</artifactId>
            <version>3.0.1</version>
        </dependency>

对于 Weld 上下文，在使用 bean-discovery-mode="all" 声明的文件夹 webapp/WEB-INF/beans.xml 中存在一个空 beans.xml .
JAX-RS 端点类如下所示:

import de.test.weld.service.AddressRepository;
import jakarta.inject.Inject;
import jakarta.ws.rs.GET;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.Produces;
import jakarta.ws.rs.core.MediaType;

@Path("address")
public class AddressApi {

    @Inject
    private AddressRepository addressRepository;

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public String getAddress() {
        return "{\"street\": \"" + addressRepository.getStreet(0) + "\", \"postcode\":  \"" +
                addressRepository.getPostcode(0) + "\", \"city\": \"" + addressRepository.getCity(0) + "\"}";
    }
}

bean AddressRepositoryImpl我要注入(inject)的注解为 @jakarta.inject.Singleton .
我将不胜感激任何提示，因此它适用于 CDI Weld。

问题是错误的依赖

<dependency>
   <groupId>org.glassfish.jersey.ext.cdi</groupId>
   <artifactId>jersey-weld2-se</artifactId>
   <version>3.0.1</version>
</dependency>

它仅适用于非 JEE 环境，即 Java 标准版 (SE) 或非 webapps。
然后仍然缺少以下依赖项:

 <dependency>
     <groupId>org.glassfish.jersey.ext.cdi</groupId>
     <artifactId>jersey-cdi1x</artifactId>
     <version>3.0.1</version>
 </dependency>
