Gemfire JDBC 연결 예외

Gemfire 서버를 시작하고 다음 주소로 바인딩합니다. myserver : 10344. (서버와 로케이터는 문제없이 시작됩니다.) 그런 다음 GFSH와 클라이언트 "펄스"에 의한 연결을 확인합니다. 모든 검사가 성공적입니다. 다음 단계에서는 Java 클라이언트를 개발하고 서버에 연결할 수 없습니다.Gemfire JDBC 연결 예외

내 프로젝트는 다음과 같은 종속성 메이븐에 의해 구축

<dependency> 
     <groupId>com.pivotal.gemfirexd</groupId> 
     <artifactId>gemfirexd</artifactId> 
     <version>1.4.1</version> 
    </dependency> 
    <dependency> 
     <groupId>com.pivotal.gemfirexd</groupId> 
     <artifactId>gemfirexd-client</artifactId> 
     <version>1.4.1</version> 
    </dependency>

(모든 Gemfire 종속성이 http://dist.gemstone.com/maven/release에서 다운로드)

코드 소스 : 나는 다음과 같은 예외가

package com.mycompany.app; 
import java.sql.Connection; 
import java.sql.DriverManager; 

public class App { 

    private void connect() { 
     try { 
      Class.forName("com.pivotal.gemfirexd.jdbc.ClientDriver"); 

      String x = "jdbc:gemfirexd://myserver:10344/"; 

      System.out.println(x); 

      final Connection conn = DriverManager.getConnection(x); 

      System.out.println("Connected "); 
      conn.close(); 
      System.out.println("Disconnected"); 

     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 

    public static void main(String[] args) { 
     new App().connect(); 
    } 
}

이 게시물은 오래된 게시물이지만, 여전히 알고 싶다면 ...

jdbc url에서 지정하는 포트가 피어 - 회원 검색 포트가 아니라 client-port (기본값 1527)입니다. 당신은 로케이터를 시작

존재해야 같은 클라이언트 포트 번호에 있었다 정보 (지정하지 않는 경우, 기본값은 1527)

... 가 피어 검색을 사용 GemFireXD 로케이터 시작을했습니다 : 로컬 호스트 [10334] 주소의 로컬 호스트에서 GemFireXD 로케이터에 대한 네트워크 서버를 시작/127.0.0.1 [1527]

는 다음과 같이 JDBC URL이 있어야한다 :

문자열 X = "JDBC : gemfirexd을 : // myserver를 : 1527/";
