Java TomcatV8.5上的RESTAPI测试程序抛出错误（eclipse和无eclipse）

我只是被这个问题困住了。我一直想做的就是尝试一个RESTAPI，以便从使用Jersey JAR的REST开始。 我在eclipse上有一个maven项目，其中包含以下JAR：

My web.xml看起来像：

<?xml version="1.0" encoding="UTF-8"?>
    <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">
        <display-name>Hello World</display-name>    
        <servlet>  
        <servlet-name>jersey-serlvet</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.glassfish.jersey.examples.helloworld</param-value>  
        </init-param>  
        <load-on-startup>1</load-on-startup>  
      </servlet>  
      <servlet-mapping>  
        <servlet-name>jersey-serlvet</servlet-name>  
        <url-pattern>/rest/*</url-pattern>  
      </servlet-mapping>  

    </web-app>

有人能帮忙吗

非常感谢。

虽然上面说“Servlet映射指定了一个未知的Servlet名称[jersey serlvet]”，但我检查了web.xml中名称的正确性。你想发布

web.xml

，但却发布了

pom.xml

。啊。谢谢更正！我刚刚试用了你的

web.xml

，效果不错。部署在Tomcat 8.5.5上。如果问题仍然存在，请发布pom.xml，我会检查。@ujulu嗨，我想我丢失了Servlet容器罐。现在它工作了！
