部署應用程序時得到的異常在GlassFish服務

Question

這裏是實體bean類

package retail.model.vo; 

import java.io.Serializable; 
import java.util.List; 


import javax.persistence.Column; 

import javax.persistence.Entity; 
import javax.persistence.GeneratedValue; 
import javax.persistence.GenerationType; 
import javax.persistence.Id; 
import javax.persistence.Table; 

@Entity 
@Table(name = "CUSTOMER") 
//@TransactionAttribute(value=REQUIRED) 

public class Customer implements Serializable{ 

    /** 
    * 
    */ 
    private static final long serialVersionUID = 5256938732963606407L; 
    private int customer_id; 
    private String name; 
    private String address; 
    private String email_id; 
    private int phNumber; 
    private List<Customer> customer; 

    @Id 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    @Column(name = "customer_id") 
    public int getCustomer_id() { 
     return customer_id; 
    } 

    public void setCustomer_id(int customer_id) { 
     this.customer_id = customer_id; 
    } 

    @Column(name = "Name") 
    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

    @Column(name = "addres") 
    public String getAddress() { 
     return address; 
    } 

    public void setAddress(String address) { 
     this.address = address; 
    } 

    @Column(name = "email_add") 
    public String getEmail_id() { 
     return email_id; 
    } 

    public void setEmail_id(String email_id) { 
     this.email_id = email_id; 
    } 

    @Column(name = "ph_number") 
    public int getPhNumber() { 
     return phNumber; 
    } 

    public void setPhNumber(int phNumber) { 
     this.phNumber = phNumber; 
    } 



    public List<Customer> getCustomerList() { 
     return customer; 
    } 

    public void setCustomerList(List<Customer> customerList) { 
     this.customer = customerList; 
    } 

    public String validate(){ 
      if(name!=null && name!=""){ 
      System.out.println("chandan"); 
      return "viewCustomerDetails"; 
      } 
      else{ 
      return "viewCustomerDetails"; 
      } 
      } 
} 

當部署變得異常以下。

Answer 1

添加映射到您的customerList

@OneToMany(targetEntity=Customer.class, mappedBy="mappedFieldInCustomer", fetch=FetchType.LAZY /* or EAGER */) 
public List<Customer> getCustomerList() { 
    return customer; 
}
