ssh整合。hibernate 使用注释映射 提示 Catalog is not mapped [from Catalog]

[qq_29551609]

.Java 代码如下
package ysl.shop.model;

import java.util.HashSet;
import java.util.Set;

import javax.persistence.Column;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.OneToMany;
import javax.persistence.OneToOne;
import javax.persistence.SequenceGenerator;
import javax.persistence.Table;

import org.hibernate.annotations.Cascade;
import org.hibernate.annotations.CascadeType;
import org.hibernate.annotations.Entity;
import org.hibernate.annotations.GenericGenerator;

/**
* Catalog entity. @author MyEclipse Persistence Tools
*/

@Entity
@Table(name="catalog")
public class Catalog implements java.io.Serializable {
@Id
@Column(name="catalogid")
@GenericGenerator(name="y" , strategy="increment")
@GeneratedValue(generator="y")
private Integer catalogid;
@Column(name="catalogname")
private String catalogname;

/* private Set computers = new HashSet(0);*/





public Catalog() {
}
public Catalog(String catalogname, Set computers) {
this.catalogname = catalogname;
/* this.computers = computers;*/
}

public Integer getCatalogid() {
return this.catalogid;
}

public void setCatalogid(Integer catalogid) {
this.catalogid = catalogid;
}

public String getCatalogname() {
return this.catalogname;
}

public void setCatalogname(String catalogname) {
this.catalogname = catalogname;
}

/* public Set getComputers() {
return this.computers;
}
*/
}



applicationContext.xml如下
