H2で動作するようにHibernateを構成しようとしていますが
Configuration cfg = new Configuration().configure();
、呼び出すとnew Configuration()
、次のように出力されます。
מאי 01, 2012 5:10:41 PM org.hibernate.annotations.common.Version <clinit>
INFO: HCANN000001: Hibernate Commons Annotations {4.0.1.Final}
מאי 01, 2012 5:10:41 PM org.hibernate.Version logVersion
INFO: HHH000412: Hibernate Core {4.1.1}
מאי 01, 2012 5:10:41 PM org.hibernate.cfg.Environment <clinit>

מאי 01, 2012 5:10:41 PM org.hibernate.cfg.Environment buildBytecodeProvider
INFO: HHH000021: Bytecode provider name : javassist
しかし、これは実行を停止しません...この後、.configure()
出力の呼び出しは次のようになります。
מאי 01, 2012 5:14:39 PM org.hibernate.cfg.Configuration configure
INFO: HHH000043: Configuring from resource: /hibernate.cfg.xml
מאי 01, 2012 5:14:39 PM org.hibernate.cfg.Configuration getConfigurationInputStream

מאי 01, 2012 5:14:39 PM org.hibernate.cfg.Configuration doConfigure
INFO: HHH000041: Configured SessionFactory: null
これらのメッセージはどういう意味ですか?
hibernate.cfg.xml:
<session-factory>

テーブルを表すクラスの1つ:
@Entity
public class Distance {
private Course courseA, courseB;
private Long MinDistance, Cost;
@Id
@GeneratedValue(generator="increment")
@GenericGenerator(name="increment", strategy = "increment")
private Long id;
public Distance() {
super();
}
public Distance(Course courseA, Course courseB, Long minDistance, Long cost) {
super();
this.courseA = courseA;
this.courseB = courseB;
MinDistance = minDistance;
Cost = cost;
}
@Override
public String toString() {
return "Distance [courseA=" + courseA + ", courseB=" + courseB
+ ", MinDistance=" + MinDistance + ", Cost=" + Cost + "]";
}
public Course getCourseA() {
return courseA;
}
public void setCourseA(Course courseA) {
this.courseA = courseA;
}
public Course getCourseB() {
return courseB;
}
public void setCourseB(Course courseB) {
this.courseB = courseB;
}
public Long getMinDistance() {
return MinDistance;
}
public void setMinDistance(Long minDistance) {
MinDistance = minDistance;
}
public Long getCost() {
return Cost;
}
public void setCost(Long cost) {
Cost = cost;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
}
ありがとうございました。
