Javers「jv_commit」不存在

我試圖讓Javer與我的項目安裝。我使用Hibernate JPA，我相信我已經正確配置了一切。Javers「jv_commit」不存在

這裏是我的Spring配置：

<bean id="auditDataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> 
    <property name="driverClassName" value="${jdbc.driverClassName}"/> 
    <property name="url" value="${jdbc.audit.url}"/> 
    <property name="username" value="${jdbc.audit.username}"/> 
    <property name="password" value="${jdbc.audit.password}"/> 
    <property name="maxActive" value="100"/> 
    <property name="maxWait" value="1000"/> 
    <property name="poolPreparedStatements" value="true"/> 
    <property name="defaultAutoCommit" value="true"/> 
    <property name="validationQuery" value="${jdbc.validationQuery}"/> 
    <property name="testOnBorrow" value="true"/> 
</bean> 

<bean id="auditSessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" destroy-method="destroy"> 
    <property name="dataSource" ref="auditDataSource"/> 
    <property name="configLocation" value="classpath:hibernate.audit.cfg.xml"/> 
    <property name="hibernateProperties"> 
     <props> 
      <prop key="hibernate.dialect">${hibernate.dialect}</prop> 
      <prop key="hibernate.query.substitutions">true 'Y', false 'N'</prop> 
      <prop key="hibernate.cache.use_second_level_cache">true</prop> 
      <prop key="hibernate.show_sql">false</prop> 
      <prop key="hibernate.format_sql">false</prop> 
      <prop key="hibernate.use_sql_comments">false</prop> 
      <!--<prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop>--> 
      <prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory</prop> 
      <!-- Hibernate Search index directory --> 
      <prop key="hibernate.search.default.indexBase">${app.search.index.basedir}</prop> 
     </props> 
     <!-- Turn batching off for better error messages under PostgreSQL --> 
     <!-- hibernate.jdbc.batch_size=0 --> 
    </property> 
</bean> 

<!-- Transaction manager for a single Hibernate SessionFactory (alternative to JTA) --> 
<bean id="auditTransactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"> 
    <property name="sessionFactory" ref="auditSessionFactory"/> 
</bean> 

<bean id="javersRepoConnectionProvider" class="com.dsc.discus.ng.audit.javers.JaversRepoConnectionProvider"> 
    <constructor-arg name="dataSource" ref="auditDataSource"/> 
</bean> 

<bean id="auditController" class="com.dsc.discus.ng.audit.javers.JaversAuditController"> 
    <constructor-arg name="javersRepoConnectionProvider" ref="javersRepoConnectionProvider"/> 
    <constructor-arg name="transactionManager" ref="auditTransactionManager"/> 
</bean>

的JaversAuditController豆：

public class JaversAuditController extends AuditController { 
private final JaversSqlRepository javersSqlRepository; 
private final Javers javers; 

public JaversAuditController(JaversRepoConnectionProvider javersRepoConnectionProvider, PlatformTransactionManager transactionManager) { 
    javersSqlRepository = SqlRepositoryBuilder.sqlRepository() 
      .withConnectionProvider(javersRepoConnectionProvider) 
      .withDialect(DialectName.MYSQL) 
      .build(); 

    javers = TransactionalJaversBuilder.javers() 
      .withTxManager(transactionManager) 
      .withObjectAccessHook(new HibernateUnproxyObjectAccessHook()) 
      .withMappingStyle(MappingStyle.BEAN) 
      .registerJaversRepository(javersSqlRepository) 
      .build(); 
} 

@Override 
public void addModified(BaseEntity entity) { 
    addModified(entity, null); 
} 

@Override 
public void addModified(BaseEntity entity, Map<String, String> extraParams) { 
    if (javers != null && entity != null) { 
     if (extraParams != null) { 
      javers.commit(entity.getModifiedBy(), entity, extraParams); 
     } 
     else { 
      javers.commit(entity.getModifiedBy(), entity); 
     } 
    } 
} 

public JaversSqlRepository getJaversSqlRepository() { 
    return javersSqlRepository; 
} 

public Javers getJavers() { 
    return javers; 
}

我不得不使用BEAN的映射風格，因爲JPA註釋是對實體的存取。

這裏是JaversRepoConnectionProvider豆：

public class JaversRepoConnectionProvider implements ConnectionProvider { 
private DataSource dataSource; 

public JaversRepoConnectionProvider(DataSource dataSource) { 
    this.dataSource = dataSource; 
} 

@Override 
public Connection getConnection() throws SQLException { 
    return dataSource.getConnection(); 
}

}

我做了人工審覈。也就是說，每次保存一個實體時，我都會調用javers.commit（）方法。碰巧，我試圖保存的第一件事情導致MySQL語法錯誤，指出表「jv_commit」不存在。該文檔指出必要的表格會自動創建，所以我必須缺少一些東西。請提前告知和感謝。

JaVers在啓動時創建它的表，很難猜測爲什麼表沒有在您的情況下創建表。這可能是由數據庫錯誤引起的。你的javers日誌裏有什麼？ –

這讓我指出了正確的方向。謝謝。 TransactionalJaversBuilder.build（）方法不確保創建表。 – MiseryMachine

事實證明，所述TransactionalJaversBuilder.javers（）建立（）方法不保證這些表被創建，像標準JaversBuilder.javers（）建立（）方法。我不確定這是否是TransactionalJaversBuilder中的錯誤。我的解決方法是Javers對象建立後致電ensureSchema（）：

public JaversAuditController(JaversRepoConnectionProvider javersRepoConnectionProvider, PlatformTransactionManager transactionManager) { 
    javersSqlRepository = SqlRepositoryBuilder.sqlRepository() 
      .withConnectionProvider(javersRepoConnectionProvider) 
      .withDialect(DialectName.MYSQL) 
      .build(); 


    javers = TransactionalJaversBuilder.javers() 
      .withTxManager(transactionManager) 
      .withObjectAccessHook(new HibernateUnproxyObjectAccessHook()) 
      .withMappingStyle(MappingStyle.BEAN) 
      .registerJaversRepository(javersSqlRepository) 
      .build(); 

    javersSqlRepository.ensureSchema(); 
}

您正在提前得出結論。 –

在Spring應用程序，例如Javers應註冊爲一個Spring bean。當txManager準備就緒時，JaVers使用@PostConstruct註釋和Spring調用ensureSchema()。

見JaversTransactionalDecorator IMPL：

@PostConstruct 
public void ensureSchema() { 
    TransactionTemplate tmpl = new TransactionTemplate(txManager); 
    tmpl.execute(new TransactionCallbackWithoutResult() { 
     @Override 
     protected void doInTransactionWithoutResult(TransactionStatus status)  { 
      javersSqlRepository.ensureSchema(); 
     } 
    }); 
}

在你的情況，因爲你已經在你的控制器中創建的Javers實例，而不是作爲一個Spring bean這種方法不叫。你應該配置你的應用程序爲文檔說 - https://javers.org/documentation/spring-integration/#jpa-entity-manager-integration
