Hibernate cannot create table when the entity annotation? - mysql

Question

My web project ,spring spring-mvc and hibernate,when the tomcat start there is no tables created in mysql db. why? and no error info
the sessionFactory
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>
<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
<prop key="hibernate.format_sql">${hibernate.format_sql}</prop>
</props>
</property>
<property name="packagesToScan">
<list>
<value>com.woodcoder.bean</value>
</list>
</property>
</bean>
the properties
hibernate.hbm2ddl.auto=update
hibernate.show_sql=true
hibernate.format_sql=false
and I tried hibernate.hbm2ddl.auto=create, it's the same.
Why hibernate doesn't create a table?
The Entity
#Entity
#Table(name="user_bean")
public class UserBean extends BaseBean {
private String username;
private String password;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
the baseEntity
#MappedSuperclass
public class BaseBean implements Serializable{
/**
* ID
*/
#Id
#Column(name="id",length = 32, nullable = true)
#GeneratedValue(generator = "uuid")
#GenericGenerator(name = "uuid", strategy = "uuid")
private String id;
#Column(updatable = false)
private Date createDate;
private Date modifyDate;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public Date getCreateDate() {
return createDate;
}
public void setCreateDate(Date createDate) {
this.createDate = createDate;
}
public Date getModifyDate() {
return modifyDate;
}
public void setModifyDate(Date modifyDate) {
this.modifyDate = modifyDate;
}

Answer 1

yes,i got the problem.
in the hibernate config there are some space in the end of each line,although i cant see them.i delete these space,the table was created.
hibernate.hbm2ddl.auto=update
hibernate.show_sql=true
hibernate.format_sql=false
