休眠空指针在AbstractUserTypeHibernateIntegrator用户类型

这里是我的Spring配置对Hibernate片段休眠空指针在AbstractUserTypeHibernateIntegrator用户类型

<bean id="adminDataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close"> 
     <property name="driverClassName" value="org.postgresql.Driver"/> 
     <property name="url" value="org.postgresql.Driver"/> 
     <property name="username" value="username"/> 
     <property name="password" value="password"/> 
    </bean> 


    <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> 
     <property name="dataSource" ref="adminDataSource"/> 
     <property name="packagesToScan" value = "mypackage.model"/> 
     <property name="jpaVendorAdapter"> 
      <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter" /> 
     </property> 
     <property name="jpaProperties"> 
      <props> 
       <prop key="hibernate.hbm2ddl.auto">true</prop> 
       <prop key="hibernate.dialect">${hibernate.sql.dialect}</prop> 
       <prop key="hibernate.connection.pool_size">${hibernate.connection.pool_size}</prop> 
       <prop key="hibernate.format_sql">true</prop> 
       <prop key="hibernate.connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</prop> 
       <prop key="hibernate.connection.driver_class">org.postgresql.Driver</prop> 
       <prop key="hibernate.multiTenancy">SCHEMA</prop> 
       <prop key="hibernate.tenant_identifier_resolver">mypackage.SchemaResolver</prop> 
       <prop key="hibernate.multi_tenant_connection_provider"mypackage.MultitenantConnectionProvider</prop> 
      </props> 
     </property> 
    </bean> 

    <bean id = "transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> 
     <property name="entityManagerFactory" ref="entityManagerFactory"/> 
    </bean>

这里是我的SchemaResolver类

public class SchemaResolver implements CurrentTenantIdentifierResolver { 

    @Override 
    public String resolveCurrentTenantIdentifier() { 
     return "public"; //TODO: Implement service to identify tenant like: userService.getCurrentlyAuthUser().getTenantId(); 
    } 

    @Override 
    public boolean validateExistingCurrentSessions() { 
     return false; 
    } 
}

这是我的MultitenantConnectionProvider

public class MultitenantConnectionProvider implements MultiTenantConnectionProvider, ServiceRegistryAwareService { 

    private static final long serialVersionUID = 4368575201221677384L; 

    private C3P0ConnectionProvider connectionProvider = null; 

    @Override 
    public boolean supportsAggressiveRelease() { 
     return false; 
    } 

    @Override 
    public void injectServices(ServiceRegistryImplementor serviceRegistry) { 
     Map lSettings = serviceRegistry.getService(ConfigurationService.class).getSettings(); 

     connectionProvider = new C3P0ConnectionProvider(); 
     connectionProvider.injectServices(serviceRegistry); 
     connectionProvider.configure(lSettings); 
    } 

    @Override 
    public boolean isUnwrappableAs(Class clazz) { 
     return false; 
    } 

    @Override 
    public <T> T unwrap(Class<T> clazz) { 
     return null; 
    } 

    @Override 
    public Connection getAnyConnection() throws SQLException { 
     final Connection connection = connectionProvider.getConnection(); 
     return connection; 
    } 

    @Override 
    public Connection getConnection(String tenantIdentifier) throws SQLException { 
     final Connection connection = getAnyConnection(); 
     try { 
      connection.createStatement().execute("SET SCHEMA '" + tenantIdentifier + "'"); 
     } 
     catch (SQLException e) { 
      throw new HibernateException("Could not alter JDBC connection to specified schema [" + tenantIdentifier + "]", e); 
     } 
     return connection; 
    } 

    @Override 
    public void releaseAnyConnection(Connection connection) throws SQLException { 
     try { 
      connection.createStatement().execute("SET SCHEMA 'public'"); 
     } 
     catch (SQLException e) { 
      throw new HibernateException("Could not alter JDBC connection to specified schema [public]", e); 
     } 
     connectionProvider.closeConnection(connection); 
    } 

    @Override 
    public void releaseConnection(String tenantIdentifier, Connection connection) throws SQLException { 
     releaseAnyConnection(connection); 
    } 
}

一旦运行我的应用程序是我得到的例外

你能告诉我们你正在使用哪个版本的spring和hibernate吗？ – M2je 2014-12-05 13:54:53

看起来像“type”为空。我猜想你的一个实体没有正确映射。或者也许一个枚举或子类在某处失踪？ – Zeki 2014-12-05 14:36:33

@ M2je添加了有关我正在使用的版本的信息。我是否应该包含jadira用户类型版本？ – user962206 2014-12-05 15:43:57

我有相同的错误，使用Hibernate 4.3.6和Jadira usertype 4.0.0.GA.

我的猜测是库Jadira usertype 4.0.0.GA与Hibernate的多租户模式不兼容。

我的解决方案是删除usertype依赖项，显然不要在代码中使用它。 现在，您必须选择使用hibernate多租户或使用usertype。

有关详细信息，用户类型使用deprecaded API ConnectionProvider getConnectionProvider()因为MultiTenantConnectionProvider不是ConnectionProvider一个实例，返回多租户模式无效。在多租户模式下，不存在ConnectionProvider类型的服务。 Usertype应该使用JdbcConnectionAccess。

我希望它会在下一个版本中修复。

多租户的问题在Jadira 5.0.0.GA中解决。免责声明：我维护Jaira。 – 2015-12-15 01:26:02

这是Usertype 3.2.0.GA中引入的一种回归。降级到版本3.1.0.GA消除了这个例外。

有关错误报告，请参阅https://github.com/JadiraOrg/jadira/issues/19。

或者，升级到Jadira的5.0.0.GA解决了Hibernate 5.0的问题。免责声明：我维护Jadira。 – 2015-12-15 01:25:29

我同意@Chris Pheby，你可以通过将Jadira版本升级到5.0.0来修复它.GA
