一、结构

二、model层

1.

  1. package org.jpwh.model.helloworld;
  2.  
  3. import javax.persistence.Entity;
  4. import javax.persistence.GeneratedValue;
  5. import javax.persistence.GenerationType;
  6. import javax.persistence.Id;
  7.  
  8. /*
  9. Every persistent entity class must have at least the <code>@Entity</code> annotation.
  10. Hibernate maps this class to a table called <code>MESSAGE</code>.
  11. */
  12. @Entity
  13. public class Message {
  14.  
  15. /*
  16. Every persistent entity class must have an identifier
  17. attribute annotated with <code>@Id</code>. Hibernate maps
  18. this attribute to a column named <code>ID</code>.
  19. */
  20. @Id
  21. /*
  22. Someone must generate identifier values; this annotation enables
  23. automatic generation of IDs.
  24. */
  25. @GeneratedValue//(strategy=GenerationType.TABLE)
  26. private Long id;
  27.  
  28. /*
  29. You usually implement regular attributes of a persistent class with private
  30. or protected fields, and public getter/setter method pairs. Hibernate maps
  31. this attribute to a column called <code>TEXT</code>.
  32. */
  33. private String text;
  34.  
  35. public String getText() {
  36. return text;
  37. }
  38.  
  39. public void setText(String text) {
  40. this.text = text;
  41. }
  42. }

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.
