Multitenant configuration: StaleObjectStateException on Transaction (hibernate + spring-data-jpa)

i'm trying to setup a configuration for manage a multi-tenant enviroment with spring-boot, spring-data-jpa, hibernate and mysql (same schema, every tenant table has a tenant_code column). For dependencies the parent maven project is spring-boot-starter-parent (2.1.2.RELEASE).

On save entity hibernate throws this exception: org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect) :

The highlights steps are:

  1. Intercept "tenant code" with custom spring HandlerInterceptorAdapter (i read oauth2 token and extract custom attribute "tenant code");
  2. Save "tenant code" in a @RequestScope bean; 

  3. On Save
  4. Define an custom hibernate EmptyInterceptor to intercept onSave action and previously set the "tenant code" (taken on a @RequestScope bean) 

  5. On Read
  6. In abstract Entity (extended by all my entities) i define @Filter and set it via AOP

If in interceptor i override onSave method i get this exception:

org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect) : [com.test.module.api.domain.entity.User#22]

Here the code: 

Spring Interceptor from Request Header:

    @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;
    }
}


Class to setup inteceptor in hibernate:

    @Component
public class TenantHibernateInterceptorCustomizer implements HibernatePropertiesCustomizer {

    @Autowired
    private TenantJpaInterceptor jpaInterceptor;

    @Override
    public void customize(Map&lt;String, Object&gt; hibernateProperties) {
        hibernateProperties.put("hibernate.session_factory.interceptor", jpaInterceptor);
    }

}


Hibernate custom interceptor:

    @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&lt;?&gt;) entity).setTenandCode(currentUser.getTenantCode());
            //if i comment this line everythings works (without tenant code)
            ((TenantAuditable&lt;?&gt;) entity).setTenandCode("TEST");            
        }
        return false;
    }
}


Service layer:

    @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;
}

I expected a insert/update sql query with filled tenant_code field.

According to (3.3) doc/sample, You should implement your (jpa) interceptor like:

@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;
}

I’am surprised that it worked with “TEST”…

Your Data Architecture: Simple Best Practices for Your Data Strategy

If you accumulate data on which you base your decision-making as an organization, you should probably think about your data architecture and possible best practices.

If you accumulate data on which you base your decision-making as an organization, you most probably need to think about your data architecture and consider possible best practices. Gaining a competitive edge, remaining customer-centric to the greatest extent possible, and streamlining processes to get on-the-button outcomes can all be traced back to an organization’s capacity to build a future-ready data architecture.

In what follows, we offer a short overview of the overarching capabilities of data architecture. These include user-centricity, elasticity, robustness, and the capacity to ensure the seamless flow of data at all times. Added to these are automation enablement, plus security and data governance considerations. These points from our checklist for what we perceive to be an anticipatory analytics ecosystem.

Multitenant configuration: StaleObjectStateException on Transaction (hibernate + spring-data-jpa)

i'm trying to setup a configuration for manage a multi-tenant enviroment with spring-boot, spring-data-jpa, hibernate and mysql (same schema, every tenant table has a tenant_code column). For dependencies the parent maven project is spring-boot-starter-parent (2.1.2.RELEASE).

On save entity hibernate throws this exception: org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect) :

The highlights steps are:

  1. Intercept "tenant code" with custom spring HandlerInterceptorAdapter (i read oauth2 token and extract custom attribute "tenant code");
  2. Save "tenant code" in a @RequestScope bean; 

  3. On Save
  4. Define an custom hibernate EmptyInterceptor to intercept onSave action and previously set the "tenant code" (taken on a @RequestScope bean) 

  5. On Read
  6. In abstract Entity (extended by all my entities) i define @Filter and set it via AOP

If in interceptor i override onSave method i get this exception:

org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect) : [com.test.module.api.domain.entity.User#22]

Here the code: 

Spring Interceptor from Request Header:

    @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;
    }
}


Class to setup inteceptor in hibernate:

    @Component
public class TenantHibernateInterceptorCustomizer implements HibernatePropertiesCustomizer {

    @Autowired
    private TenantJpaInterceptor jpaInterceptor;

    @Override
    public void customize(Map&lt;String, Object&gt; hibernateProperties) {
        hibernateProperties.put("hibernate.session_factory.interceptor", jpaInterceptor);
    }

}


Hibernate custom interceptor:

    @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&lt;?&gt;) entity).setTenandCode(currentUser.getTenantCode());
            //if i comment this line everythings works (without tenant code)
            ((TenantAuditable&lt;?&gt;) entity).setTenandCode("TEST");            
        }
        return false;
    }
}


Service layer:

    @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;
}

I expected a insert/update sql query with filled tenant_code field.

Often, it’s finding the most cost-effective, scalable way to store and process boundless volumes of data in multiple formats that come from a growing number of sources. Then organizations need the analytical capabilities and flexibility to turn this data into insights that can meet their specific business objectives.

This Refcard dives into how a data lake helps tackle these challenges at both ends — from its enhanced architecture that’s designed for efficient data ingestion, storage, and management to its advanced analytics functionality and performance flexibility. You’ll also explore key benefits and common use cases.

Introduction

As technology continues to evolve with new data sources, such as IoT sensors and social media churning out large volumes of data, there has never been a better time to discuss the possibilities and challenges of managing such data for varying analytical insights. In this Refcard, we dig deep into how data lakes solve the problem of storing and processing enormous amounts of data. While doing so, we also explore the benefits of data lakes, their use cases, and how they differ from data warehouses (DWHs).


This is a preview of the Getting Started With Data Lakes Refcard. To read the entire Refcard, please download the PDF from the link above.

Everything you need to know about Spring Data JPA

In this post, I cover everything you need to know about Spring Data JPA so you can use this library more confidently in your Spring Boot application. I have seen there are a lot of confusion about when to use CrudRepository  or JpaRepository , so I will cover that as well.

What is Spring Data JPA?

As the official documentation from Spring says “Spring Data JPA makes it easy to implement JPA based repositories. It improves and eases the implementation of the JPA-based data access layer. Overall, data access applications are easier to implement.”

With Spring Data JPA, one can avoid a lot of boilerplate code for Java Persistent API (JPA) in the application. The library also makes it easy to query the data from the database taking away a lot of implementation for SQL queries from a developer.

As a developer, you only write repository interfaces including any custom methods and Spring Data JPA will provide the most implementation automatically.

Spring Data JPA + QueryDSL: Taking the Best From Both Worlds

An example of combining the two most powerful frameworks for building a maintainable and type-safe persistence layer; from Spring Data JPA we will take only CRUD operations and for all complex queries we will use QueryDSL.

You can find the full project on GitHub using this link. There is a simple SpringBoot application with configured MySQL data source and initial database structure described as a Flyway migration.

Here we will concentrate only on the building persistence layer. As we deal with the relational database we will rely on the JPA specification. Let’s take a simple entity model like Author/Book as an example:
