关于hibernate实体类映射成表

[农妇山泉有点田]

以下是实体类内容：

@SuppressWarnings("serial")
@Entity
@Table(name = "cust_user")
public class User implements Serializable {

	// id
	private Integer id;
	// 用户名
	private String name;
	// 密码
	private String password;
	// 昵称
	private String nickname;
	// 性别
	private String sex;
	// 电子邮件
	private String email;
	// 真实姓名
	private String realName;
	// 出生日期
	private String brithday;
	// 城市
	private String city;

	@Id
	@Column(name = "USR_ID", length = 20)
	@GeneratedValue(strategy = GenerationType.AUTO)
	public Integer getId() {
		return id;
	}

	@Column(name = "USR_NAME", length = 20)
	public String getName() {
		return name;
	}

	@Column(name = "USR_PASSWORD", length = 20)
	public String getPassword() {
		return password;
	}

	@Column(name = "USER_NICKNAME", length = 20)
	public String getNickname() {
		return nickname;
	}
	
	@Column(name = "USER_SEX", length = 20)
	public String getSex() {
		return sex;
	}

	@Column(name = "USER_EMAIL", length = 20)
	public String getEmail() {
		return email;
	}

	@Column(name = "USER_REAL_NAME", length = 20)
	public String getRealName() {
		return realName;
	}

	@Column(name = "USER_BIRTHDAY", length = 20)
	public String getBrithday() {
		return brithday;
	}

	@Column(name = "USER_CITY", length = 20)
	public String getCity() {
		return city;
	}

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

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

	public void setPassword(String password) {
		this.password = password;
	}

	public void setNickname(String nickname) {
		this.nickname = nickname;
	}

	public void setSex(String sex) {
		this.sex = sex;
	}

	public void setEmail(String email) {
		this.email = email;
	}

	public void setRealName(String realName) {
		this.realName = realName;
	}

	public void setBrithday(String brithday) {
		this.brithday = brithday;
	}

	public void setCity(String city) {
		this.city = city;
	}

以下是hibernate配置:

<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">
					org.hibernate.dialect.MySQLDialect
				</prop>
				
				<prop key="current_session_context_class">thread</prop>
				
				<prop key="hibernate.show_sql">true</prop>
				
				<prop key="hibernate.format_sql">true</prop>
				
				<prop key="hibernate.hbm2ddl.auto">create</prop>
				
				<prop key="org.hibernate.tool.hbm2ddl">create</prop>
			</props>
		</property>

映射的表结构：


声明:id,name,password是之前就有的，可以映射，后来我又在实体类里添加了一些字段，为什么就不能映射了呢？求高手。坐等高手。

两种建议措施： 1.不知道更改了实体类过后是否同步更改了hibernate的映射文件； 2.还是不行就将此表删除 重新创建
