Spring Hibernate 整合项目案例之@Entity注解

Hibernate: insert into users (username) values (?)
数据库中的表名为users-->对应java实体类Users{Users.java或者users.java(不区分大小写)}
或者使用注解@table（name=“users”）
列名username-->对应实体类Users中的属性username
实体Users类的代码：（Users.java）

import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.Id;@Entitypublic class Users {private int id;private String username;@Id@GeneratedValuepublic int getId() {return id;}public void setId(int id) {this.id = id;}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}}

<!--注意红色字体部分，原因前面介绍过，spring2.5以后注解开启则将LocalSessionFactoryBean换成AnnotationSessionFactoryBean的方式了-->
