Hibernate Version Migration Drift

hibernate-migration-drift

Upgrading from Hibernate 5 to 6 (via Spring Boot) silently changes mapping and runtime semantics, so stale entity state, generator/sequence handling, and annotation/config compatibility break persistence and JSON exposure expectations.

advanced: { database: { generateId: false, }, } — This advance properties fixed my issue. Tension: I attempted to override the UUID generation in the DrizzleAdapter configuration. Outcome: This advance properties fixed my issue.

MATCHESSolution

without using reWriteBatchedInserts inserts will not be merged — set batch_size > 1. Tension: Hibernate send multiple statement in the same time and not merging them into multi-valued INSERT. Outcome: without using reWriteBatchedInserts inserts will not be merged.

MATCHESSolution

annotate fields(ex: id) with `sequenceGenerator` not the Entity or class — @Entity @Table(name = "ENTITY") public class ENTITY extends PanacheEntityBase. Tension: those values are inconsistent. Outcome: @Id @SequenceGenerator(name = "ID_SEQ", sequenceName = "ID_SEQ", allocationSize =100) public Integer id;.

MATCHESSolution

Here's the only change I had to make: — to allow you migrate to Hibernate 6. Tension: the solution must work with named queries. Outcome: @Enumerated(EnumType.STRING) @Type(PostgreSQLEnumType.class).

MATCHESSolution

set this property in the application.properties file — This can be because the table is not present in your schema in the database. Tension: if the table does not exist then it will create or if the table exists then alter the table. Outcome: spring.jpa.hibernate.ddl-auto= update.

MATCHESSolution

a workaround for this — when directly fetching objects using findById. Tension: the bug is still there. Outcome: There is an existing bug in Hibernate 6.2.

MATCHESSolution

Spring Boot 4 introduced some major changes where, by default, it uses Jackson 3 instead of Jackson 2. Outcome: making it a more suitable candidate over the no-arg counterpart.

MATCHESSolution

`spring-boot-starter-aop` has been renamed to `spring-boot-starter-aspectj` — Replace that in your pom.xml. Outcome: it will run fine.

MATCHESSolution

Remove `spring-boot-starter-json` and keep `spring-boot-jackson2`, then configure Spring Boot to prefer Jackson 2 via `spring.http.converters.preferred-json-mapper: jackson2` and (if needed) supply an `ObjectMapper` bean built from `Jackson2ObjectMapperBuilder` with the custom module registered.

MATCHESSolution

Use a stable 3.x version or a proper `4.0.x-SNAPSHOT` — `start.spring.io` shows Spring Boot 4.x SNAPSHOTs. Tension: using `4.0.0` (without `-SNAPSHOT`) in the parent POM breaks dependency management. Outcome: with the Spring snapshot repository configured.

MATCHESSolution

Spring Boot 4. Tension: Spring Boot 4 modularizes the codebase so various things are moved to different modules/dependencies.

MATCHESSolution

But you can try this workaround solution to see if this works: — spring-cloud-gcp-starter-secretmanager 7.3.2. Tension: enforce Spring Cloud GCP 7.x to use Spring Cloud Context 5.0.0. Outcome: which uses Spring Boot 4.0.0 starters.

MATCHESSolution

Take a look at Blaze Persistence entity view. Tension: that approach will lead to some complexity and cause errors.

MATCHESSolution

Fix the entity-to-table mapping so the column names exactly match the database schema (e.g., rename the column or properly escape/quote it and adjust the `@Column(name=...)` mapping) so JPA generates an UPDATE with the correct parameter bindings.

MATCHESSolution

If you see 2 versions of JPA — Spring Boot 3.3.x pulling in Spring Data JPA 3.3.x but another library in your project bringing an older Spring Data JPA. Tension: then remove the older version. Outcome: remove the older version.

MATCHESSolution

Use the latest HikariCP 6.3.0, the problem has been fixed in that version. — The above problem was not fixed in HikariCP version 5.0.1. Outcome: implementation("com.zaxxer:HikariCP:6.3.0").

MATCHESSolution

it's totally fine to use plain Hibernate without Spring Data JPA — especially if you want more control. Tension: But you lose access to many helpful features.

MATCHESSolution

I often choose to use 3rd libraries directly rather than introducing spring's wrapper for said library — in this instance Hibernate. Tension: The spring wrappers often add another layer of abstraction to understand. Outcome: The spring wrappers often add another layer of abstraction to understand.

MATCHESSolution

To solve this you could downgrade to hibernate 5.4.x. Tension: however the project looks inactive to me. Outcome: create a pull request for querydsl to support hibernate 6.x.

MATCHESSolution

Make the common superclass an @Entity and use JPA inheritance (e.g., @Inheritance with JOINED/TABLE_PER_CLASS/SINGLE_TABLE) so the container can reference the entity type. Then map the collection as a relationship to the base entity type (or use an association table/discriminator via the chosen inheritance strategy), rather than storing IDs as a workaround.

MATCHESSolution

Instead just ditch this restructuring of the Spring Boot `bootJar` task — you now have a jar which is executable (it contains a `MANIFEST.MF` with all the proper entries). Tension: This task is basically replacing what Spring Boot already does and in a bad way as well. Outcome: let it do its thing instead of trying to be smarter.

MATCHESSolution

Removing `orderId(UUID.randomUUID())` from order Builder works like a charm. — The error occurs because the `@Id` field (`orderId`) is annotated with `@GeneratedValue(strategy = GenerationType.AUTO)`. Tension: Hibernate automatically generates the value for this field. Outcome: Removing `orderId(UUID.randomUUID())` from order Builder works like a charm.

MATCHESSolution

Align all Spring Boot/Spring Security/Authorization Server dependency versions (e.g., upgrade the Spring Boot plugin to the same version and remove hardcoded version overrides), and prefer using org.springframework.boot:spring-boot-starter-oauth2-authorization-server so transitive dependencies match.

MATCHESSolution

After remove this row it run perfectly — previously I did specify spring framework as 6.1.14. Tension: conflict between dependency that include in 3.4.x. Outcome: it run perfectly.

MATCHESSolution

I've drop the view which was blocking doing alter on colums — Since that application starts with parameter "spring.jpa.hibernate.ddl-auto" set to "update" without erros. Tension: According to @M.Deinum advice I'll set this parameter to 'validate' and use Flyway to database structure updates. Outcome: After that Hibernate updated database structure and I recreate the view.

MATCHESSolution

for custom JPA configuration. Outcome: Modify to this:.

MATCHESSolution

You can achieve this by enabling a couple of settings: — Instancio.of(PersonEntity.class). Outcome: withSetting(Keys.BEAN_VALIDATION_ENABLED, true) .withSetting(Keys.JPA_ENABLED, true) .create();.

MATCHESSolution

calls requesting the Provider afterwards do not work (the user returns null — after a Spring 5 -> 6 (Spring Boot 3.3.4) migration. Tension: I can sign in to my site, but calls requesting the Provider afterwards do not work. Outcome: I fixed this today, and found the following out that helped resolve this in my custom filter code.

MATCHESSolution

future hand-authored migrations. Outcome: A CI guard that diffs `packages/db/src/migrations/*.sql` filenames against `meta/_journal.json` tags would catch this class of bug at PR time.

MATCHESSolution

Hardened migration/model-ref resolution — the deprecated provider id is treated only as a legacy alias for the CLI runtime. Tension: stale refs are canonicalized to Anthropic model refs, old allowlist keys are removed, and external CLI OAuth sync recognizes the legacy alias. Outcome: external CLI OAuth sync recognizes the legacy alias.
