java - JAX-RS:Tomcat正常运行，但找不到根目录(404)

我刚刚为我的RESTful Web API启动了JAX-RS（泽西岛）。 Tomcat可以正常运行，但是找不到root（错误404）。

错误控制台如下：

SEVERE: Servlet [Jersey REST Service] in web application [/com.G8.ws] threw load() exception

我的简单代码如下，因为我的包名称是com.G8.ws，所以我将http://localhost:8080/com.G8.ws

package com.G8.ws;


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

@Path("/v1/status")
public class V1_status {

    @GET
    @Produces(MediaType.TEXT_HTML)
    public String returnTitle(){
        return "<p>RESTful Web API using JAX/RS</p>";
    }

}

以下是我的web.xml：

<init-param>
  <!--   <param-name>com.sun.jersey.config.property.packages</param-name>-->

</servlet>
<servlet-mapping>
<servlet-name>Jersey REST Service</servlet-name>
<url-pattern>/api/*</url-pattern>
</servlet-mapping>

</web-app>

而且，我已将所有jar文件下载到jersey-archive-1.19中。

有什么事吗

最佳答案

您需要2.x捆绑或将声明的ServletContainer更改为1.x version。

<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>

如果更改为1.x版本，则应改用注释掉的程序包扫描属性

<param-name>com.sun.jersey.config.property.packages</param-name>
