java - 服务器Tomcat v8.5无法启动Hello World Jersey Web Service

我正在设置我的Jersey Web服务，但无法运行它，Apache Tomcat 8.5出错了。有关简单代码，我的库和错误，请参见下面的详细信息。

我创建了一个动态Web项目...
我添加了我的Jersey文件...（我错过了吗？）


javax.ws.rs-api.2.0.1.jar
jersey-client.jar
jersey-common.jar
jersey-contaner-servlet.jar
jersey-container-servlet.jar
jersey-media-jaxb.jar
jersey-server.jar


我的Web.xml

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <!-- The package where your resource classes are -->
        <param-value>WS</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>testApi</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>
</web-app>

我的Java课

package ws;
import javax.ws.rs.*;
import javax.ws.rs.core.*;

    @Path("test")
    public class Connect {
        @GET
        @Path("test")
        @Produces(MediaType.TEXT_PLAIN)
        public String hello(){
            return "hello world";
        }
    }

我的错误之前弹出说无法启动Apachev8.5

最佳答案

您缺少jersey-guava.jar，其中应该包含Google Guava类的软件包重新打包的版本，包括Function。 Jersey重新包装了所需的确切版本，因此您仍可以从其原始包装结构中使用您喜欢的Guava版本。请参见https://stackoverflow.com/a/22069399/27905。
