Hibernate联合主键重写equals和hashCode方法

可简单参照利用

public class StudentPK implements java.io.Serializable {
private int id;
private String name;

public int getId() {
return id;
}

public void setId(int id) {
this.id = id;
}

public String getName() {
return name;
}

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

@Override
public boolean equals(Object o) {
if (o instanceof StudentPK) {
StudentPK pk = (StudentPK) o;
if (this.id == pk.getId() && this.name.equals(pk.getName())) {
return true;
}
}
return false;
}

@Override
public int hashCode() {
return this.name.hashCode();
}
}
