Spring Boot Hibernate Filter

DodaTech 1 min read

In this tutorial, you'll learn about Fix Spring Boot Hibernate @Filter Not Applying. We cover key concepts, practical examples, and best practices.

The Problem

Hibernate @Filter annotated on entities does not filter query results.

Quick Fix

Define @FilterDef

Wrong:

@FilterDef(name = "activeFilter") // No parameters

Output:

Filter missing params

Right:

@FilterDef(name = "activeFilter", parameters = @ParamDef(name = "active", type = "boolean"))
@Filter(name = "activeFilter", condition = "active = :active")

Output:

Filter defined with parameters

Enable filter in session

Wrong:

// Filter not enabled
entityManager.find(Product.class, 1L);

Output:

Filter not applied

Right:

Session session = entityManager.unwrap(Session.class);
session.enableFilter("activeFilter").setParameter("active", true);

Output:

Filter applied to session

Use @FilterJoinTable for collections

Wrong:

@Filter(name = "activeFilter", condition = "active = :active")
private List<Item> items;

Output:

Collection not filtered

Right:

@FilterJoinTable(name = "activeFilter", condition = "active = :active")
private List<Item> items;

Output:

Collection association filtered

Prevention

  • Use @FilterDef and @Filter annotations
  • Enable filter on Session before queries
  • Use @FilterJoinTable for collection associations

Common Mistakes with boot hibernate filter

  1. Mixing let bindings with <- bindings in do notation, producing type errors
  2. Overlapping type class instances that cause GHC to reject the program with ambiguous dispatch errors
  3. Non-exhaustive pattern matches that compile with warnings then crash at runtime

These mistakes appear frequently in real-world SPRING code. DodaTech's contributors have identified these patterns through analysis of open-source projects and production systems.

Practice Exercise

Write a pure function that safely divides two integers using Maybe, then test it with edge cases like division by zero and negative numbers.

This exercise reinforces the concepts covered in this guide. Try implementing it before checking online solutions.

FAQ

### Why does @Filter not filter collection associations?

Use @FilterJoinTable instead of @Filter for collection join table filtering.
