import org.hibernate.annotations.GenericGenerator; 

@Entity

public class Event { 
    private Long id; 

    private String title; 
    private Date date; 

    public Event() { 
     // this form used by Hibernate 
    } 

    public Event(String title, Date date) { 
     // for application use, to create new events 
     this.title = title; 
     this.date = date; 
    } 

    @Id 
    @GeneratedValue(generator="increment_generator") 
    @GenericGenerator(name="increment_generator", strategy = "increment") 
    public Long getId() { 
     return id; 
    } 

    private void setId(Long id) { 
     this.id = id; 
    } 

    @Temporal(TemporalType.TIMESTAMP) 
    @Column(name = "EVENT_DATE") 
    public Date getDate() { 
     return date; 
    } 

    public void setDate(Date date) { 
     this.date = date; 
    } 

    public String getTitle() {

    } 

    public void setTitle(String title) {

Answer 1

sessionFactory豆で、あなたは財産annotatedClassesがcom.chicago.home.Event .Howeverの値を持って宣言しているため、コンポーネント・スキャンcom.chicago.home

Answer 2

、このクラスが存在しないので、春の苦情がそれを見つけたことができない間、あなたのクラスはパッケージorg.chicago.homeです。

実際には、イベントはorg.chicago.homeパッケージにありますが、com.chicago.homeパッケージには含まれていません。
