spring - Update or SaveorUpdate in CRUDRespository, Is there any options available -

i trying crud operations entity bean. crudrepository provide standard methods find, delete , save there no generic method available saveorupdate(entity entity) in turn calls hibernate or hibernatetemplate sessions saveorupdate() methods.

the way crudrepository provides functionality use this

@modifying @query("update space c set c.owner = :name c.id = :id") integer setnameforid(@param("name") string name, @param("id") 

but not generic , needs written complete form fields. please let me know if there way or can session of hibernate or object of spring hibernatetemplate solve issue.

the implementation of method

<s extends t> s save(s entity)

from interface

crudrepository<t, id extends serializable> extends repository<t, id>

automatically want. if entity new call persist on entity manager, otherwise call merge

the code looks this:

public <s extends t> s save(s entity) {      if (entityinformation.isnew(entity)) {         em.persist(entity);         return entity;     } else {         return em.merge(entity);     } } 

and can found here. note simplejparepository class automatically implements crudrepository in spring data jpa.

therefore, there no need supply custom saveorupdate() method. spring data jpa has covered.
