Question

这是我的java模型类 - CustomerProperty.java

package model;

import java.io.InputStream;

public class CustomerProperty {

public CustomerProperty() {

}

public int propertyid;
public String name;
public String phone;
public String occupation;
public String address1;
public String address2;
public String postcode;
public String city;
public String state;
public String payment;
public InputStream photo;
public String agent;
public String IDproject;
public String[] quickSale;
public String ICnumber;
public String bag;
public String mydate;

public int getPropertyid() {
    return propertyid;
}

public void setPropertyid(int propertyid) {
    this.propertyid = propertyid;
}

public String getName() {
    return name;
}

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

public String getPhone() {
    return phone;
}

public void setPhone(String phone) {
    this.phone = phone;
}

public String getICnumber() {
    return ICnumber;
}

public void setICnumber(String ICnumber) {
    this.ICnumber = ICnumber;
}

public String getICNUMBER() {
    return ICnumber;
}

public void setICNUMBER(String ICnumber) {
    this.ICnumber = ICnumber;
}

public String getOccupation() {
    return occupation;
}

public void setOccupation(String occupation) {
    this.occupation = occupation;
}

public String getAddress1() {
    return address1;
}

public void setAddress1(String address1) {
    this.address1 = address1;
}

public String getAddress2() {
    return address2;
}

public void setAddress2(String address2) {
    this.address2 = address2;
}

public String getPostcode() {
    return postcode;
}

public void setPostcode(String postcode) {
    this.postcode = postcode;
}

public String getCity() {
    return city;
}

public void setCity(String city) {
    this.city = city;
}

public String getState() {
    return state;
}

public void setState(String dateTime) {
    this.state = dateTime;
}

public String getPayment() {
    return payment;
}

public void setPayment(String payment) {
    this.payment = payment;
}

public InputStream getPhoto() {
    return photo;
}

public void setPhoto(InputStream photo) {
    this.photo = photo;
}

public String getAgent() {
    return agent;
}

public void setAgent(String agent) {
    this.agent = agent;
}

public String getIDproject() {
    return IDproject;
}

public void setIDproject(String IDproject) {
    this.IDproject = IDproject;
}

public String[] getQuickSale() {
    return quickSale;
}

public void setQuickSale(String[] quickSale) {
    this.quickSale = quickSale;
}

public String getMyDate() {
    return mydate;
}

public void setMyDate(String mydate) {
    this.mydate = mydate;
}

每当我的JSP调用这个java类时，它只能检测原始元素。我添加了一个新元素 - mydate，它就像永远无法检测到它。

以下是错误代码。

pe异常报告

messageInternal Server Error

description服务器遇到阻止它的内部错误   完成此请求。

例外

org.apache.jasper.JasperException：javax.el.PropertyNotFoundException：   班级＆＃39; model.CustomerProperty＆＃39;没有财产   ＆＃39;数值指明MyDate＆＃39 ;.根本原因

我试图删除java类并再次重新创建，但是，JSP只能检测我的前16个元素而不是任何新添加的元素。

任何解决方案？感谢

Answer 1

注意你的getter setters -

public String mybag() {
    return mydate;
}

public void setmybag(String mydate) {
    this.mydate = mydate;
}

应该是setMydate和getMydate。不是吗？

更新 -

案例敏感。

public String mydate;

这应该是

public String myDate;

您的JSP应该是abc.myDate而不是abc.mydate

<td><c:out value="${abc.mydate}" /></td>

JSP无法检测java模型类中新添加的元素
