我试图在我的名为 customer 的表中显示所有行，但它正在迭代同一行。

例如：我有两行具有不同的值，但第一行打印了两次。请多多指教。

public List listCustomers(String cifNumber_){
    SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
    Session session = sessionFactory.openSession();
    Transaction tx = null;
    Customer cntct = null;
    try{
         tx = session.beginTransaction();
         Query sql = session.createQuery("from Customer");
         List cntctList = sql.list();          
         Object obj[] = cntctList.toArray();
         for(int i=0; i<obj.length; i++)
         {
     System.out.println("length " +obj.length);
     cntct = (Customer)obj[i]; 
     System.out.println(cntct.getId()); 
     System.out.println(cntct.getCifNumber());
     System.out.println(cntct.getCustomerName());
     System.out.println(cntct.getIdCountry());
                }

客户.java

package com.java.vinoth;

public class CustomerSearchActionForm extends org.apache.struts.action.ActionForm{
private int id;
private String customerName;
private String cifNumber;
private int idNumber;

    return id;

    this.id = id;
}

    return customerName;

public void setCustomerName(String customerName) {
    this.customerName = customerName;

public String getCifNumber() {
    return cifNumber;
}
public void setCifNumber(String cifNumber) {
    this.cifNumber = cifNumber;

    this.idNumber = idNumber;

public void setMaster_id(int master_id) {
    this.master_id = master_id;

public String getRmCode() {
    return rmCode;

    this.rmCode = rmCode;

public String getCustomerCountry() {
    return customerCountry;

public void setCustomerCountry(String customerCountry) {
    this.customerCountry = customerCountry;
}
public String getMessage() {
    return message;

public void setMessage(String message) {
    this.message = message;
}

找到了根本原因，这是因为我的 id 列在映射文件中设置为主键，但在表中未设置为主键。

在我将 id 添加到主键后，此问题已得到解决。
