![]() ![]() Suppose we are going to define and map relationships for the following entities: Book, Category, Author, and Publisherīook has multiple bidirectional relationship with others which can cause a StackOverflow error. Mysql-connector-java provides MySQL Java Client Spring-boot-starter-data-jpa provides Hibernate ORM and autoconfigure Spring DataSource Spring-boot-starter-data-rest auto-builds REST API based on JPA and Hibernate entities As to Lombok, reproduction must include generated class since Jackson has no special support for Lombok so everything is based on just class definition and annotations. Ideally without either Lombok or Hibernate, to show a problem in core databind: if so, issue belongs here With Hibernate, but without Lombok, adding classes as post-processed by Lombok (if that's how it works - I don't use Lombok myself). You can create and init a new Spring Boot project by using Spring Initializr or your IDEįollowing is the final project structure with all the files we would create ├── src If Hibernate is required part, bug needs to be filed for jackson-datatype-hibernate since Hibernate proxying is typically involved. MapStruct Example of Mapping JPA/Hibernate Entity with DTO Check out the following tutorial as one of the approaches I thought hibernate takes into consideration only instance variables that are annotated with Column. In practice, you may also like to handle the JPA and Hibernate circular references/dependencies problem with the DTO design pattern. 221 This question already has answers here : What is the easiest way to ignore a JPA field during persistence (10 answers) Closed 6 years ago. This tutorial will walk you through the steps of creating an example on handling circular references/dependencies of JPA and Hibernate entity bidirectional relationships with Jackson Spring Data REST and MySQL ![]()
