java - 在 Wildfly 上使用 Spring Boot 战争应用程序查找远程 EJB 时出错

Question

我最终希望创建一个支持 EJB 3+、传统 HTTP 请求以及最终 JPA/Hibernate 的 RESTful API。我正在使用 Eclipse 版本 2021-03，运行 JBOSS Wildfly 服务器，使用接口创建远程 EJB（类似于此处），最后使用 Spring boot 制作 REST API。

更新- 2021 年 4 月 22 日

根据日志输出，远程 EJB 被创建并且 RESTful 路由在 Web 服务器上工作。客户端 pom.xml 中有 EJB 依赖项的条目，我能够注入 EJB 依赖项，但是在查找过程中出现命名异常。我已多次检查 JNDI 绑定信息，但仍然出现异常。任何帮助将不胜感激。

EJB 远程代码

HelloStatefulWorld.java

@Remote
public interface HelloStatefulWorld {

    int howManyTimes();
    String getHelloWorld();
}

HelloStatefulWorldEJB.java

@Stateful(name="HelloStatefulWorld")
public class HelloStatefulWorldEJB implements HelloStatefulWorld {

    private int howManyTimes = 0;

    public int howManyTimes() {
        return howManyTimes;
    }

    public String getHelloWorld() {
        howManyTimes++;
        return "Hello Stateful World!";
    }
}
