java - URL 无法找到我的 Web 应用程序上下文 – Java Enterprise Beans - Wildfly

Question

我有一个结合了 RESTful 服务和 MySQL 数据库的 EJB 应用程序。我想在我的 Wildfly 服务器上部署此应用程序。我已经配置了所有内容，到目前为止，当我想通过 Wildfly 服务器上的 Eclipse 启动应用程序时没有错误。问题是我无法通过浏览器访问资源 - 我想调用 http://localhost:8080/REST-EJB-ArticleService/v1/articles在我的浏览器中访问我的资源，但我得到 404。看来该应用程序未在我的网络服务器上发布。

以下是我启动应用程序时的输出摘录:

我通过右键单击项目启动应用程序 - 在服务器上运行(Wildfly 运行正常)

但我希望在教程中出现类似的内容，一个链接，我可以在其中看到我的 ejb 正在哪个地址上运行。

这是我的 ejb 类:

@Path("/v1/articles")
@Stateless
public class ArticleResourceEJB
{

    @Inject
    private ArticleDAO dao;

    public ArticleResourceEJB()
    {
        System.out.println(ArticleResourceEJB.class.getName() + " created");
    }


    @POST
    @Consumes({"application/xml", "application/json"})
    public void insert(ArticleDTO user)
    {
        System.out.println("insert: " + user);

        dao.createArticle(user.getDescription(), user.getPrice());
    }


    @PUT
    @Consumes("application/xml")
    public void update(ArticleDTO dto)
    {
        System.out.println("update to " + dto);

        dao.update(dto.toArticle());
    }


    @DELETE
    @Path("{id}")
    public void delete(@PathParam("id") int id)
    {
        System.out.println("delete: " + id);

        // TODO
    }


    @GET
    @Produces({"application/xml", "application/json"})
    public List<ArticleDTO> findAll()
    {
        System.out.println("findAll()");

        List<Article> list = dao.findAll();
        List<ArticleDTO> result = ArticleDTO.toArticleDTOList(list);
        System.out.println("size = " + result.size());
        return result;
    }


    @GET
    @Path("{id}")
    @Produces("application/xml")
    public ArticleDTO findById(@PathParam("id") int id) 
    {
        System.out.println("findById(" + id + ")");

        Article article = dao.findById(id);
        return new ArticleDTO(article);
    }
}

Answer 1

看来您的上下文名称错误。我认为您部署的工件的名称(您的应用程序的名称)是“MovieWebService”，因此 url 应该类似于 localhost:8080/MovieWebService/pathToYourService/pathToMethod

不太确定它是否必须是 .jar ，我通常会将可部署工件设为 .war 或 .ear部署到 Wildfly。
