When saving entity converted from a DTO, hibernate throws TransientPropertyValueException: object references an unsaved transient instance"
问题 First off - I know, it might seem like the same question has been asked a million times. However, this is related rather to DTOs, not entities nor missing cascades. If I create an entity myself and save it, everything is fine. The problem occurs when I create a DTO, convert it with ModelMapper and then try to save the converted entity. If you look at the test class, the first test(saveCarByEntity) passes but the second(saveCarByDto) one produces the error. Every class connected can be seen

Entity To DTO Conversion for a Spring REST API
1. Overview In this tutorial, we'll handle the conversions that need to happen between the internal entities of a Spring application and the external DTOs (Data Transfer Objects) that are published back to the client. 2. Model Mapper Let's start by introducing the main library that we're going to use to perform this entity-DTO conversion – ModelMapper . We will need this dependency in the pom.xml : 1 2 3 4 5 < dependency > < groupId >org.modelmapper</ groupId > < artifactId >modelmapper</ artifactId > < version >2.3.5</ version > </ dependency > To check if there's any newer version of this
How to have ModelMapper.validate() succeed when using converters and providers instead of property mapping?
问题 Having something like: @Getter @Setter public static class Entity { private int hash; private LocalDateTime createdTime; } and @Getter @Setter public static class DTO { private String hash; private String createdTime; } I need birectional mapping so I should be able to map Entity -> DTO -> Entity . In this example the property type happens to be LocalDateTime but could be any type that needs parsing from String or so (just to say that I am not after better way to map LocalDateTime but in
How to map a DTO to an existing JPA entity?
问题 I'm trying to map a Java DTO object to an existing JPA entity object without having to do something like the following: public MyEntity mapToMyEntity(SomeDTO dto, MyEntity entity) { entity.setField1(dto.getField1()); entity.setField2(dto.getField2()); ... entity.setField20(dto.getField20()); return entity; } Up to now I've been using ModelMapper like so: MyEntity entity = modelMapper.map(dto, SomeDTO.class); , but what I'm trying to do instead is map to an existing entity object rather than
