Testcontainers JAX-RS集成测试异常，请求技术排查指导

我近期正在开发一个JAX-RS小型应用以熟悉相关技术，同时尝试使用Testcontainers编写集成测试。该应用部署在Tomcat容器中本地测试正常，但使用Payara Micro容器执行测试时出现404错误。我尝试过将应用部署到TomEE和Payara服务器，也均未成功。以下是相关配置代码、测试代码及错误日志，恳请有相关经验的人士提供指导：

Dockerfile #

FROM tomcat:9-jdk11-openjdk

RUN rm -rf /usr/local/tomcat/webapps/ROOT

COPY target/restapp.war /usr/local/tomcat/webapps/ROOT.war

EXPOSE 8080

CMD ["catalina.sh", "run"]

web.xml配置 #

JAX-RS路由代码 #

package com.jchaaban.javaeerestapp;


import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Application;
import javax.ws.rs.core.MediaType;

@Path("/greet")
public class SpeakerApplication extends Application {
    @GET
    @Path("/hello")
    @Produces(MediaType.APPLICATION_JSON)
    public String sayHello() {
        return "Hello";
    }

}
