Tomcat이 내 웹 응용 프로그램에 대해 404를 반환합니다.

Question

Tomcat 8.5에 배포 된 Jersey 2 응용 프로그램이 있습니다. 앱 URL로 이동하면 HTTP 404가 표시됩니다. 도움을주십시오. 나는 이것에 관해 여러 가지 질문을 보았지만 셋업에 무엇이 잘못되었는지를 알 수 없다. 로그에 오류가 없습니다.

내 애플 :

package com.mydomain; 

import javax.json.Json; 
import javax.json.JsonObject; 

import javax.ws.rs.GET; 
import javax.ws.rs.Path; 
import javax.ws.rs.PathParam; 
import javax.ws.rs.Produces; 
import javax.ws.rs.core.MediaType; 
import javax.ws.rs.core.Response; 

@Path("/") 
public class MyClass { 
    @GET 
    @Produces(MediaType.APPLICATION_JSON) 
    public Response defaultEntry() { 
     JsonObject result = (Json.createObjectBuilder() 
          .add("test", "OK") 
          .build()); 

     return Response.status(200).entity(result).build(); 
    } 
} 

web.xml은 :

<?xml version="1.0" encoding="UTF-8"?> 
<web-app 
    xmlns="http://java.sun.com/xml/ns/j2ee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> 

    <servlet> 
    <servlet-name>myapp</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.mydomain.MyClass</param-value> 
    </init-param> 
    <load-on-startup>1</load-on-startup> 
    </servlet> 

    <servlet-mapping> 
    <servlet-name>myapp</servlet-name> 
    <url-pattern>/*</url-pattern> 
    </servlet-mapping> 

</web-app> 

이 앱은 ${CATALINA_HOME}/webapps에 배포됩니다. 앱과 함께 myapp이라는 디렉토리가 있습니다. 내가 사용하는 URL은 localhost:8080/myapp입니다.

도와주세요.

Answer 1

저지 2와

당신이 실제로 web.xml에 필요하지 않습니다 서블릿 (3), 주석이 충분해야합니다. 프로젝트에서 web.xml을 제거해보십시오.

Answer 2

예제보기 Jax-RS Servlet 3.0 maven Tomcat 일반적으로 새 Servlet 3.0의 경우 응용 프로그램을로드하기 위해 web.xml이 필요하지 않습니다. 그러나 당신은 클래스를 확장해야합니다 응용 프로그램 :

package com.vvirlan.java.ws; 

import java.util.HashSet; 
import java.util.Set; 
import javax.ws.rs.ApplicationPath; 
import javax.ws.rs.core.Application; 

import com.vvirlan.java.ws.resources.Hello; 

@ApplicationPath("/rest") 
public class MyApplication extends Application { 

@Override 
public Set<Class<?>> getClasses() { 
final Set<Class<?>> returnValue = new HashSet<Class<?>>(); 
returnValue.add(Hello.class); 
return returnValue; 
} 
}
