使用 docker compose 部署的 CXF Web 服务将无法工作

Question

使用 spring/spring boot/spring cloud 几年后。我决定从基础开始学习 Jakarta EE

我有 CXF 基本 JAXRS Web 服务，带有虚拟 api，可以通过 CLI 在本地工作

(

java -jar my-app.jar

)

但是，一旦我使用 docker-compose 部署它，请求就不会执行（失败）

API 请求是：

http://localhost:333/hello/persons

应返回：

[{"id":1,"name":"A"},{"id":1,"name":"B"}]

但是我在底部执行 docker-compose up docker-compose-yml 文件请求失败了

这是pom.xml：

这是主要功能和类：

package org.example;

import com.fasterxml.jackson.jakarta.rs.json.JacksonJsonProvider;
import org.apache.cxf.endpoint.Server;
import org.apache.cxf.jaxrs.JAXRSServerFactoryBean;

import java.util.logging.Logger;

public class WebServer {

    private static final Logger logger = Logger.getLogger(WebServer.class.getName());

    public static void main(String[] args) throws InterruptedException {
        logger.info("Starting server...");
        JAXRSServerFactoryBean factoryBean = new JAXRSServerFactoryBean();
        factoryBean.setResourceClasses(SimpleController.class);
        factoryBean.setProvider(new JacksonJsonProvider());
        factoryBean.setAddress("http://localhost:333/");
        Server server = factoryBean.create();
        server.start();
        Thread.currentThread().join();
    }
}

这是虚拟 API

@Path("hello")
public class SimpleController {

    @GET
    @Path("persons")
    @Produces(MediaType.APPLICATION_JSON)
    public List<Person> getPersons() {
        return List.of(new Person(1, "A"), new Person(1, "B"));
    }
}

docker文件：

FROM alpine:edge
RUN apk add --no-cache openjdk17
RUN apk --no-cache add curl
EXPOSE 333
COPY target/my-app.jar /app/my-app.jar
WORKDIR /app
ENTRYPOINT ["java","-jar","my-app.jar"]

factoryBean.setAddress("http://localhost:333/");

-->

factoryBean.setAddress("http://0.0.0.0:333/");
