嗨，我想使用 struts2 在文本框中显示 bean 值，但它不起作用，请帮忙。即使我尝试设置并从 bean 中获取值，但仍然无法正常工作。我已附上输出。

Customer.java 


package com.java.bean;

 public class Customer {
private int id;
private String customerName;
private String cifNumber;
private int idNumber;
private String idCountry;
private String idType;
private int master_id;
private String rmCode;
private String customerCountry;

public int getId() {
    return id;
}
public void setId(int id) {
    this.id = id;
}
public String getCustomerName() {
    return customerName;
}
public void setCustomerName(String customerName) {
    this.customerName = customerName;
}
public String getCifNumber() {
    return cifNumber;
}
public void setCifNumber(String cifNumber) {
    this.cifNumber = cifNumber;
}
public int getIdNumber() {
    return idNumber;
}
public void setIdNumber(int idNumber) {
    this.idNumber = idNumber;
}
public String getIdCountry() {
    return idCountry;
}
public void setIdCountry(String idCountry) {
    this.idCountry = idCountry;
}
public String getIdType() {
    return idType;
}
public void setIdType(String idType) {
    this.idType = idType;
}
public int getMaster_id() {
    return master_id;
}
public void setMaster_id(int master_id) {
    this.master_id = master_id;
}
public String getRmCode() {
    return rmCode;
}
public void setRmCode(String rmCode) {
    this.rmCode = rmCode;
}
public String getCustomerCountry() {
    return customerCountry;
}
public void setCustomerCountry(String customerCountry) {
    this.customerCountry = customerCountry;
}
