Hi my question is not technical. I want to know if hibernate 5 supports XML based entity mapping or not.
My requirement is like below :
I want a backend on Jersey-Hibernate. My front end is Android application. I want to keep my Entity POJOs in a common project such that they will be shared by both app and server. Gson will serialize/deserialize both side. But because android application doesn't support all java library in compilation, I don't want my common(POJO) depending on some library; In this case hibernate annotations. So I am planning to use XML based configuration.
Hibernate allows you to work with persistent XML data in much the same way you work with persistent POJOs. A parsed XML tree can be thought of as another way of representing the relational data at the object level, instead of POJOs. Hibernate supports dom4j as API for manipulating XML trees.
xml is/will be deprecated and will be replaced by some sort of “extended JPA orm. xml” mapping in Hibernate 7.
These types are “clob”, “blob”, “binary”, “text” etc. Clob and blob data types are present to maintain the data type mapping of large objects like images and videos.
hibernate mappings are one of the key features of hibernate . they establish the relationship between two database tables as attributes in your model. that allows you to easily navigate the associations in your model and criteria queries.
Hibernate 5 supports both the legacy HBM
mappings as well as the JPA XML mappings too. However, HBM
mappings are no longer the recommended approach to map entities. As illustrated in the new User Guide, all examples make use of annotations.
There are more features provided by Hibernate-specific annotations than it is the case with HBM
mappings. In Hibernate 6, it is planned to add an extension mechanism to the JPA XML mappings, therefore HBM
mappings are deprecated.
Since you are migrating to Hibernate 5, it's a good idea to migrate from HBM
to annotations too.
Yes, according to documentation (where authors recommended using annotations for mapping) is said that xml mapping is still possible: docs
So on - you can still us *.hbm.xml
for entity mapping.
EDIT: ofc I mean *.hbm.xml
