oracle 드라이버가 Maven 저장소에 추가되었을 때 데이터베이스에 연결할 수 없습니다.

Question

데이터베이스에 정보를 읽거나 쓰는 간단한 웹 서비스를 작성하려고합니다. 나는 오라클 드라이버 ojdbc6을 pom.xml에 종속성으로 추가 할 수 없으므로 아래 mvn install 명령을 사용하여 추가했습니다.

package com.nt.dao; 

import org.hibernate.SessionFactory; 
import org.hibernate.Transaction; 
import org.hibernate.cfg.Configuration; 
import org.hibernate.classic.Session; 

import com.nt.dto.ProductDTO; 

public class ProductServiceDAO { 

    public ProductDTO getProductInfo(long productId) { 
     System.out.println("session---------1-"); 
     SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory(); 
     System.out.println("session---------2-"); 
     Session session = sessionFactory.openSession(); 
     ProductDTO productDTO = new ProductDTO(); 
     productDTO.setProductName("Apple"); 
     Transaction transaction = session.beginTransaction(); 
     System.out.println("session---------3-"); 
     productDTO = (ProductDTO) session.get(ProductDTO.class, productId); 
     session.close(); 
     return productDTO; 
    } 
} 

내가 프로그램을 실행하려고, 내가받은 :

mvn install:install-file -Dfile=C:\ojdbc6.jar -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0 -Dpackaging=jar 

ojdbc6.jar 성공적으로 가 [ojdbc6.jar] [1]

가

데이터베이스에서 제품 정보를 검색하려는 내 DAO 클래스는 추가되었다 아래 예외. 도와주세요.

이제 작동 중입니다. 내 수업에 아래 코드 줄을 추가했습니다.

Class.forName ("oracle.jdbc.OracleDriver"); 

하지만 여기서 또 다른 문제에 직면하고 있습니다. 내 "제품"테이블에는 아래 스크린 샷과 같은 레코드가 있습니다. products

SOAPUI에서 레코드를 검색하려고하면 검색되지 않습니다. 또한 레코드가 삭제됩니다.

package com.nt.dto; 

    import javax.xml.bind.annotation.XmlAccessType; 
    import javax.xml.bind.annotation.XmlAccessorType; 
    import javax.xml.bind.annotation.XmlElement; 
    import javax.xml.bind.annotation.XmlType; 

    @XmlType(name="ProductDTO") 
    @XmlAccessorType(XmlAccessType.FIELD) 
    public class ProductDTO { 
     @XmlElement 
     private int productId; 
     @XmlElement 
     private String productName; 
     @XmlElement 
     private int productPrice; 
     public int getProductId() { 
      return productId; 
     } 
     public void setProductId(int productId) { 
      this.productId = productId; 
     } 
     public String getProductName() { 
      return productName; 
     } 
     public void setProductName(String productName) { 
      this.productName = productName; 
     } 
     public int getProductPrice() { 
      return productPrice; 
     } 
     public void setProductPrice(int productPrice) { 
      this.productPrice = productPrice; 
     } 


    } 

My DAO class retrieving the record: 

package com.nt.dao; 

import org.hibernate.SessionFactory; 
import org.hibernate.Transaction; 
import org.hibernate.cfg.Configuration; 
import org.hibernate.classic.Session; 

import com.nt.dto.ProductDTO; 

public class ProductServiceDAO { 

    public ProductDTO getProductInfo(long productId) { 
     System.out.println("session---------1-"); 
     try { 
      Class.forName ("oracle.jdbc.OracleDriver"); 
     } catch (ClassNotFoundException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
     SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory(); 
     System.out.println("session---------2-"); 
     Session session = sessionFactory.openSession(); 
     ProductDTO productDTO = new ProductDTO(); 

     Transaction transaction = session.beginTransaction(); 
     System.out.println("session---------3-"+productId); 
     productDTO = (ProductDTO) session.get(ProductDTO.class, (int) productId); 
     if(productDTO!=null){ 
      System.out.println("session---------4-"+productDTO.getProductId()); 
      System.out.println("session---------5-"+productDTO.getProductName()); 
      System.out.println("session---------6-"+productDTO.getProductPrice()); 
     }else{ 
      System.out.println("session---------7-"); 
     } 

     session.close(); 
     return productDTO; 
    } 
}
