我是这个restapi的新手，今天我在eclipse中使用maven构建了一个jersey项目。我附加了maven生成的文件我使用的软件版本是java（11）tomcat（v09）jersey（3.0.0，依赖关系由maven自动注入）

1. Pom.xml

2. MyResource.java (Also generated by Maven)

    package com.jithin.demorest;

    import jakarta.ws.rs.GET;
    import jakarta.ws.rs.Path;
    import jakarta.ws.rs.Produces;
    import jakarta.ws.rs.core.MediaType;
    @Path("myresource")
    public class MyResource {
        @GET
        @Produces(MediaType.TEXT_PLAIN)
        public String getIt() {
            return "Got it!";
        }
    }

3. 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>com.jithin.demorest</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>

当我在tomcat服务器上运行它时，我得到了主页。但是当我导航到路径/webapi/myresource时，我得到了一个404错误。原因是什么。java、tomcat或jersey的版本有什么问题吗。或者我应该使用其他依赖项吗？
