HTTP Status 500 - javax.el.PropertyNotFoundException: Свойство не найдено по типу

я делаю this tutorial, и я получаю следующее сообщение об ошибке весной зимует проект MySQL:HTTP Status 500 - javax.el.PropertyNotFoundException: Свойство не найдено по типу

HTTP Status 500 - javax.el.PropertyNotFoundException: 
Property 'id' not found on type net.viralpatel.docmanager.model.Document

Что другой информации сделать я нужно отправить, чтобы люди знали, как помочь мне исправить ошибку, чтобы мое приложение запустилось?

Вот класс Документ:

@Entity 
@Table(name="documents") 
public class Document { 

    @Id 
    @GeneratedValue 
    @Column(name="id") 
    private Integer id; 

    @Column(name="name") 
    private String name; 

    @Column(name="description") 
    private String description; 

    @Column(name="filename") 
    private String filename; 

    @Column(name="content") 
    @Lob 
    private Blob content; 

    @Column(name="content_type") 
    private String contentType; 

    @Column(name="created") 
    private Date created; 

    //Getter and Setter methods 
    public Integer getID(){return id;} 
    public Blob getContent(){return content;} 
    public String getContentType(){return contentType;} 
    public String getDescription(){return description;} 
    public String getFileName(){return filename;} 
    public String getName(){return name;} 
    public Date getCreated(){return created;} 

    public void setID(Integer i){id=i;} 
    public void setContent(Blob ct){content=ct;} 
    public void setContentType(String ctype){contentType=ctype;} 
    public void setDescription(String desc){description=desc;} 
    public void setFileName(String fn){filename=fn;} 
    public void setName(String nm){name=nm;} 
    public void setCreated(){created=new java.sql.Date(System.currentTimeMillis());} 
}

Здесь часть дорожки стека, начиная с первой СУРОВОЙ:

Вот это язык определения данных, которые создали базовую таблицу MySQL :

CREATE DATABASE `docdb`; 
USE `docdb`; 

CREATE TABLE `documents` (
    `id` int(11) NOT NULL AUTO_INCREMENT, 
    `name` varchar(200) NOT NULL, 
    `description` text NOT NULL, 
    `filename` varchar(200) NOT NULL, 
    `content` mediumblob NOT NULL, /* for ORACLE enter BLOB*/ 
    `content_type` varchar(255) NOT NULL, 
    `created` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, 
    PRIMARY KEY (`id`) 
);

это работает для других столбцов? Если вы закомментируете часть 'private Integer id', вы все равно получите исключение? – Blub

Я считаю, что аксессоры id 't соответствует соглашениям об именах бинов, и поэтому исключение вызывается. Они должны быть следующими:

public Integer getId() { return id; } 

public void setId(Integer i){ id= i; }

+1 и благодарю вас за то, что вы первый, с правильным ответом. – CodeMed

Добро пожаловать. :) –

Там нет собственности называется id. Существует, однако, свойство, называемое iD.

Это проблема чувствительности кейса.

Имена свойств выведены с помощью поиска отражений на объектах.

@Entity 
@Table(name="documents") 
public class Document { 

    @Id 
    @GeneratedValue 
    @Column(name="id") 
    private Integer id; 

    //Getter and Setter methods 
    public Integer getID(){return id;} 
    ... 

    public void setID(Integer i){id=i;} 
    ... 
}

+1 и спасибо. это фактически Идентификатор, но ваша точка хорошо взята. – CodeMed

Извините, я не пытался показать предлагаемое изменение кода, но просто выделил код с проблемой. Я вижу, как это сбивает с толку :) – Brandon
