找不到url'；Java中REST服务的s

有很多关于创建REST服务的帖子，我读过几十篇；我仍然无法得到我的服务。我的服务创建（通过PUT或POST）和返回（通过GET）Offerror，它们有id、名称和地址。Offer是一个类，Offerror是一个在ConcurrentMap中保存Offerror实例的类，OfferrorServlet是servlet类。请帮我理顺我的休息；我宁愿注释类，也不愿配置web.xml

为了运行，我将工件offerWebService-0.0.1-SNAPSHOT.war部署到JBoss。我通过邮递员进行测试，接受&内容类型为application/json集，并使用admin帐户进行身份验证

得到http://localhost:8080/OfferorWebService-0.0.1-SNAPSHOT/offerrors（）生成“404未找到”

职位http://localhost:8080/OfferorWebService-0.0.1-SNAPSHOT/offerrors生成“405方法不允许”

我需要在servlet或调用中添加/更改什么？我需要额外的配置文件吗？谢谢

在pom.xml中

首先，我想你不能将这些注释与servlet结合使用，它们不是为它而设计的，我认为这不会正常工作，doGet、doPut、doTrace、doPost会很好地工作，如果你想使用java libs专注于rest服务，并且有更多的特性，你应该研究JAXR或jaxWS文档，howTo，Servlet更多地关注基本的http操作以及jsp和该模型，但是当然，您可以使用普通的Servlet，只需删除这些注释并给出所发生情况的反馈。

谢谢。我让它工作了，我稍后会发布

@WebServlet("/Offerrors")

        @Override
        public void init() {
            mapOfOfferors = new Offerors();

            String address = request.getParameter("address");
            String msg = "Creating an offeror";
            if (name == null || address == null)
                throw new RuntimeException(Integer.toString(HttpServletResponse.SC_BAD_REQUEST));

            Offeror offeror = new Offeror();
            // Save the ID of the newly created Offeror.
            offeror.setName(name);
            offeror.setAddress(address);
            int id = mapOfOfferors.addOfferor(offeror);

            try {

... (many more of the same)
