Jersey restful web应用程序为所有资源URI

标签： java rest jersey jax-rs java-9

我是宁静的Web应用程序的新手，我正试图在jersey-api的帮助下使用JAX-RS创建一个安静的Web应用程序。

当我每次获得HTTP状态404时，我试图通过某些uri访问应用程序。

请帮我解决这个问题。

以下是代码段

MessageResource.java 

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

@Path("messages")
public class MessageResource {

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String getMessages() {
        return "Hello";
    }
}

的web.xml 

<?xml version="1.0" encoding="UTF-8"?>
<!-- This web.xml file is not required when using Servlet 3.0 container,
     see implementation details http://jersey.java.net/nonav/documentation/latest/jax-rs.html -->
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
    <servlet>
        <servlet-name>Jersey Web Application</servlet-name>
        <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>jersey.config.server.provider.packages</param-name>
            <param-value>org.manjunath.webservice.messenger</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Jersey Web Application</servlet-name>
        <url-pattern>/webapi/*</url-pattern>
    </servlet-mapping>
</web-app>

Url用于访问资源 的 http://localhost:8080/messenger/webapi/messages

我正在使用版本为2.27的jersey-quickstart-webapp

附上tomcat服务器的日志
