HSQLDB схема автоматического обновления

Question

Например, у меня есть следующий объект:

@Entity 
public class MyClass { 

    @Id 
    @GeneratedValue 
    private Integer Id; 
    private String value; 
    private boolean check = false; // <-- HERE! 
    // getters & setters 

} 

Если я решу изменить имя check свойства, чтобы validate:

@Entity 
public class MyClass { 

    @Id 
    @GeneratedValue 
    private Integer Id; 
    private String value; 
    private boolean validate = false; // <-- HERE! 
    // getters & setters 

} 

Я настроил HSQLDB с:

<bean id="hikariConfig" class="com.zaxxer.hikari.HikariConfig" autowire="no" > 
    <property name="poolName" value="springHikariCP" /> 
    <property name="dataSourceClassName" value="org.hsqldb.jdbc.JDBCDataSource" /> 
    <property name="dataSourceProperties"> 
     <props> 
      <prop key="url">jdbc:hsqldb:file:${user.home}/db/data;hsqldb.lock_file=false</prop> 
      <prop key="user">sa</prop> 
      <prop key="password"></prop> 
     </props> 
    </property> 
</bean> 

<bean id="entityManagerFactory" 
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 
    <property name="dataSource" ref="dataSource" /> 
    <property name="packagesToScan" value="com.example.domain" /> 
    <property name="jpaVendorAdapter"> 
     <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" /> 
    </property> 
    <property name="jpaProperties" ref="hibernateProperties" /> 
</bean> 

<bean name="hibernateProperties" autowire="byName" 
    class="org.springframework.beans.factory.config.PropertiesFactoryBean"> 
    <property name="properties"> 
     <props> 
      <prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop> 
      <prop key="hibernate.show_sql">true</prop> 
      <prop key="hibernate.hbm2ddl.auto">update</prop> // <-- HERE! 
      <prop key="hibernate.default_schema">PUBLIC</prop> 
      <prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate4.SpringSessionContext</prop> 
      <prop key="hibernate.connection.CharSet">utf8</prop> 
      <prop key="hibernate.connection.characterEncoding">utf8</prop> 
      <prop key="hibernate.connection.useUnicode">true</prop> 
     </props> 
    </property> 
</bean> 

Поскольку для hibernate.hbm2ddl.auto установлено значение update не следует ли обновлять схему, если я вношу какие-либо изменения в код?

Я получил эту ошибку, пытаясь получить доступ к validate, потому что схема не была обновлена:

ОБНОВЛЕНО:

после включения журнала SQL я вижу это:

ERROR org.hibernate.tool.hbm2ddl.SchemaUpdate (SchemaUpdate.java:261) main :HHH000388: Unsuccessful: alter table PUBLIC.my_class add column validate boolean not null 
ERROR org.hibernate.tool.hbm2ddl.SchemaUpdate (SchemaUpdate.java:262) main :default expression needed in statement [alter table PUBLIC.my_class add column validate boolean not null] 

Я не знаю, почему это не добавление default false к заявлению. Кроме того, он пытается добавить новый столбец, а не обновлять его.

Answer 1

Эта ошибка означает, что у вас недостаточно прав на схему, в которой вы сейчас работаете.

Проверьте приведенную ниже строку.

Caused by: org.hsqldb.HsqlException: user lacks privilege or object not found: MYCLAS0_.VERIFY 

Подтвердите, есть ли у вас модификация схемы схемы для этой схемы. Используйте это link, чтобы узнать больше об этом.

Answer 2

потому что boolean не может быть null, я замечаю, что инициализация объекта validate=false не имеет никакого эффекта. Поэтому я вынужден сделать это в JPA с помощью:

@Column(columnDefinition = "boolean default false") 
private boolean validate = false;
