一、结构
二、model层
1.
package org.jpwh.model.helloworld; import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id; /*
Every persistent entity class must have at least the <code>@Entity</code> annotation.
Hibernate maps this class to a table called <code>MESSAGE</code>.
*/
@Entity
public class Message { /*
Every persistent entity class must have an identifier
attribute annotated with <code>@Id</code>. Hibernate maps
this attribute to a column named <code>ID</code>.
*/
@Id
/*
Someone must generate identifier values; this annotation enables
automatic generation of IDs.
*/
@GeneratedValue//(strategy=GenerationType.TABLE)
private Long id; /*
You usually implement regular attributes of a persistent class with private
or protected fields, and public getter/setter method pairs. Hibernate maps
this attribute to a column called <code>TEXT</code>.
*/
private String text; public String getText() {
return text;
} public void setText(String text) {
this.text = text;
}
}

For the “Hello World” application, you delegate database connection handling to a Java Transaction API ( JTA ) provider, the open source Bitronix project. Bitronix offers connection pooling with a managed java.sql.DataSource and the standard javax.transaction.UserTransaction API in any Java SE environment. Bitronix binds
these objects into JNDI , and Hibernate interfaces automatically with Bitronix through JNDI lookups.
