我试图设置一个配置来管理一个多租户环境,使用sping-start、sping-data-jpa、hibernate和mysql(相同的模式,每个租户表都有一个tenant_code列)。对于依赖项,父maven项目是sping-boo-starter-父(2.1.2.发布)。
在保存实体hibernate抛出此异常:org.hibernate.StaleObjectStateExcture:行被另一个事务更新或删除(或未保存的值映射不正确):
重点步骤包括:
如果在拦截器中我重写onSave方法,则会出现以下异常:

这里的代码是:
来自请求头的Spring拦截器:
@Component
public class TokenInterceptor extends HandlerInterceptorAdapter {
public final String TENANT_CODE = "tenant_code";
@Autowired
private CurrentUser currentUser;
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {
String tenantCode = ... extract tenant code from request...;
currentUser.setTenantCode(tenantCode);
return true;
}
}
在hibernate中设置inteceptor的类:
@Component
public class TenantHibernateInterceptorCustomizer implements HibernatePropertiesCustomizer {
@Autowired
private TenantJpaInterceptor jpaInterceptor;
@Override
public void customize(Map<String, Object> hibernateProperties) {
hibernateProperties.put("hibernate.session_factory.interceptor", jpaInterceptor);
}
}
Hibernate自定义侦听器:
@Component
public class TenantJpaInterceptor extends EmptyInterceptor {
//Comment to test if problem is about spring context
//@Autowired
//private CurrentUser currentUser;
@Override
public boolean onSave(Object entity, Serializable id, Object[] state, String[] propertyNames, Type[] types) {
if (entity instanceof TenantAuditable) {
//((TenantAuditable<?>) entity).setTenandCode(currentUser.getTenantCode());
//if i comment this line everythings works (without tenant code)
((TenantAuditable<?>) entity).setTenandCode("TEST");
}
return false;
}
}
服务层:
@Transactional
public UpsertResponse<UserDto> updateUser(UserDto userDto) {
UpsertResponse<UserDto> validationResult = CommonValidators.validateUserDto(userDto);
if(!validationResult.isValidated()) {
return validationResult;
SpUser user = userRepo.findById(userDto.getUserId()).orElse(new SpUser());
userMapper.mapUserDtoToEntity(userDto, user);
try {
SpUser savedUser = userRepo.save(user);
validationResult.setEntity(userMapper.mapUserDtoFromEntity(savedUser));
validationResult.setValidated(true);
}catch(Exception e) {
e.printStackTrace();
validationResult.setValidated(false);
validationResult.setGlobalMessage(e.getLocalizedMessage());
}
return validationResult;
}
我期望插入/更新sql查询与填充tenant_code字段。
这是完整的日志

帮个小忙吧,谢谢
根据(3.3)文档/样本,你应该实现你的(jpa)拦截器,比如:
@Override
public boolean onSave(Object entity, Serializable id, Object[] state, String[] propertyNames, Type[] types) {
if (entity instanceof TenantAuditable) {
for ( int i=0; i < propertyNames.length; i++ ) {
if ( "tenantCode".equals( propertyNames[i] ) ) {
state[i] = currentUser.getTenantCode();
return true;
}
}
}
return false;
}
我很惊讶它和“测试”一起工作...
我正在使用Spring2.x、Spring Data REST、Hibernate5.x、MySQL创建一个服务器REST应用程序。 我按照以下准则配置了多租户:https://dzone.com/articles/spring-boot-hibernate-multitenancy-implementation,唯一的区别是我使用了每个租户一个数据库。 我有一个来创建到DB的连接,还有一个来获取
我有一个KeyClope实例,为每个域创建了两个域和一个用户。 我有我的spring boot应用程序。yml(resource server-API)用于一个特定领域,并在我的代码中修复。 它正在为Realm1工作并进行验证。 但现在我可以接收来自user2(tenant2)的请求,而令牌将无效,因为公钥(realm1)对于已签名的请求jwt令牌(realm2)无效。 允许多领域多租户和动态配置
我们正在开发一个多租户应用程序。在体系结构方面,我们为业务逻辑设计了共享中间层,为数据持久性设计了每个租户一个数据库。也就是说,业务层将与每个租户的数据库服务器建立一组连接(连接池)。这意味着应用程序为每个租户维护单独的连接池。如果我们预计约有5000个租户,那么这个解决方案需要高资源利用率(每个租户的应用服务器和数据库服务器之间的连接),这会导致性能问题。 我们已经通过保持公共连接池解决了这个问
我认为为每个租户创建一个Redis实例是一个很好的解决方案。 我有一个包含租户id和Redisendpoint的映射,这是专用于这个租户的。 地图数据如下所示:
问题内容: 我正在尝试使用此网络研讨会中概述的单独的架构方法向Java应用程序添加多租户 我想知道如何通过spring来配置多个数据源,也许是通过使用属性文件并基于租户id从spring上下文中获取数据源。 更重要的是,尽管我希望能够配置支持此多租户功能的自定义连接提供程序实现,以供Hibernate使用,而不是默认使用的注入功能。 我怎样才能做到这一点。 问题答案: 使用。
问题内容: 在Spring 3应用程序中,我试图通过Hibernate 4的本机MultiTenantConnectionProvider和CurrentTenantIdentifierResolver实现多租户。我发现在Hibernate 4.1.3 中存在此问题,但是我正在运行4.1.9并仍收到类似的异常: 以下是相关代码。在I中,我现在只写了一些简单的代码,每次都只返回一个新的连接,并且在这
