javax.ws.rs.NotFoundException：RESTEASY003210：无法找到完整路径的资源：使用RestEASY，Intellij IDEA 16.1，Tomcat 8.0.33

Question

有人提出了很多问题，但是我尝试了所有建议的变体，谷歌搜索了我的问题，检查了RestEASY规范。 什么都没有帮助我。 我正在创建一个非常简单的“Hello World”应用程序。 当我写的路由到我的REST服务的URL时，我收到以下错误和浏览器中的空白页面。

这是堆栈跟踪：

        <servlet-name>V1_Status</servlet-name>
        <url-pattern>/api/*</url-pattern>
    </servlet-mapping>

</web-app>

这是我的类处理我的REST请求：

package com.taras.resty.status;

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

@ApplicationPath("/v1/status")
public class V1_Status extends Application  {
    private static final String api_version= "00.01.00";

    @GET
    @Produces(MediaType.TEXT_HTML)
    public String returnTitle(){
        return "<p>Java Web Service</p>";
    }

    @Path("/version")
    @GET
    @Produces(MediaType.TEXT_HTML)
    public String returnVersion(){
        return "<p>Version + </p>" + api_version;
    }

}

我使用的URL是： http：// localhost：8080 / api / v1 / status

先感谢您。

编辑 - 已解决对于将面临同样问题的人。 @tair帮我解决了我的错误。 试试他的版本（你可以在这里找到https://github.com/tsabirgaliev/hello-jaxrs ）。 我们还没有找到原因，它已经以某种方式消失了（魔术）。 当然，更详细的信息请查看规范http://docs.jboss.org/resteasy/docs/3.0.16.Final/userguide/html_single/index.html#d4e113

Answer 1

由于您的web.xml建议您使用与Servlets 3.1兼容的Tomcat，因此Resteasy的配置应该不同。 请参阅第3.5. Standalone Resteasy in Servlet 3.0 Containers节3.5. Standalone Resteasy in Servlet 3.0 Containers 3.5. Standalone Resteasy in Servlet 3.0 Containers官方Resteasy文档的3.5. Standalone Resteasy in Servlet 3.0 Containers [1]。

如果您坚持使用旧样式配置，则应将JAX-RS应用程序指定为HttpServletDispatcher init-param ：

<servlet>
    <servlet-name>Resteasy</servlet-name>
    <servlet-class>
        org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher
    </servlet-class>
    <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>com.taras.resty.Application</param-value>
    </init-param>
</servlet>

<servlet-mapping>
    <servlet-name>V1_Status</servlet-name>
    <url-pattern>/api/*</url-pattern>
</servlet-mapping>

<context-param>
    <param-name>resteasy.servlet.mapping.prefix</param-name>
    <param-value>/api</param-value>
</context-param>

在任何一种情况下，您都必须javax.ws.rs.Application 。

更新：这里[2]是一个完整的应用示例。 使用Tomcat 8.0.33进行测试
