Question

无法理解错误，但创建了具有以下方面的动态网络项目：

动态网络模块3.1
Java 1.8
JavaScript 1.0
Jax-RS 2.0

运行时：Websphere Application Server Liberty Profile。

这不是我的第一个具有这种配置的项目，到目前为止一切都还不错。在此项目中，尝试执行任何RESTful请求时收到以下错误：

[ERROR   ] SRVE0271E: Uncaught init() exception created by servlet [javax.ws.rs.core.Application] in application [EscapeRoom]: javax.servlet.ServletException: At least one provider or resource class should be specified for application class "javax.ws.rs.core.Application

我的web.xml：

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">

    <servlet>
        <servlet-name>javax.ws.rs.core.Application</servlet-name>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>javax.ws.rs.core.Application</servlet-name>
        <url-pattern>/api/*</url-pattern>
    </servlet-mapping>

    <welcome-file-list>
        <welcome-file>index.html</welcome-file>
    </welcome-file-list>
</web-app>

我的jax-rs课程：

@Path("/test")
public class TestGet  {

    @GET
    public String getTest(){
        return "OK!";
    }

}

非常简单。

试图在同一工作区创建另一个项目，它工作正常。

实际上我可以将我的所有前端内容从一个项目复制到另一个项目，但我不喜欢这种解决方法，并希望找到它不起作用的原因，我想我错过了一些东西明显。
