Rest 404与jersey 1.8、tomcat 7 Resful和eclipse一起未找到

我是J2EE新手，我想创建一个restful web服务，因此我遵循了一个教程，并在此基础上在eclipse（开普勒服务发行版1）中创建了一个简单的动态web应用程序项目，然后添加了jersey 1.8库，并配置了appache tomcat（apache-tomcat-7.0.50）使用eclipse，在添加index.html之后，我可以看到

http://localhost:8080/myproject/

页面内容

但我得到错误404（nt发现）与此url

http://localhost:8080/myproject/api/v1/status

及

这是java资源文件

package myproject;

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

@Path("/v1/status/*")
public class v1_status {

private static final String api_version = "00.01.00";

@GET
@Produces(MediaType.TEXT_HTML)
public String returnName(){
    return "<p>Web Services</p>";
}

@Path("/version")
@GET
@Produces(MediaType.TEXT_HTML)
public String returnVersion()
{
    return "<p>Web Services</p>" + api_version; 
}

  }

---

解决后，

@路径（“/v1/status/*”

中的星号

（*）

是问题的原因

---

删除它之后，我得到了正确的结果，因此它应该是

@Path（“/v1/status/”）

。

Jersey映射到/api/*。您的资源路径是

/status/*

。为什么您认为它会被映射到

/api/v1/status

而不是

/api/status

？@JBNizet我在测试中这样做了，资源映射实际上是映射到了“/v1/status/”，结果与旧的（404）相同。您可以尝试一下“”@indownight 404错误吗

package myproject;

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

@Path("/v1/status/*")
public class v1_status {

private static final String api_version = "00.01.00";

@GET
@Produces(MediaType.TEXT_HTML)
public String returnName(){
    return "<p>Web Services</p>";
}

@Path("/version")
@GET
@Produces(MediaType.TEXT_HTML)
public String returnVersion()
{
    return "<p>Web Services</p>" + api_version; 
}

  }
