在glassfish服務上部署應用程序時獲取異常

Question

這里是實體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";
          }
          }
}

部署時低於異常。

Answer 1

將映射添加到您的customerList

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