Here java list convertion errors are occured
Scala Code
@SuppressWarnings("unchecked")
@Override
def getAllStudents():List[Student] = {
return getSession().createQuery("from Student where isDelete = 'false' ")
.list() **here error occured and that shows below **
}
here i import this statement but no change
import scala.collection.JavaConverters._
Error type mismatch; found : java.util.List[?0] where type ?0 required: scala.collection.immutable.List[com.model.domain.entity.Student]
The Java Code
@SuppressWarnings("unchecked")
@Override
public List<Student> getAllStudents() {
return getSession().createQuery(
"from Student where isDelete = 'false' ").list();
}
Your own answer is incorrect. Instead, if you are implementing an interface (or extending a class) which needs to return a Java list, you should do this:
def getAllStudents() : java.util.List[Student] = {
getSession().createQuery("from Student where isDelete = 'false' ")
.list()
}
If you don't need Java list here, then you should instead do
import scala.collection.JavaConverters._
def getAllStudents() : Seq[Student] = {
getSession().createQuery("from Student where isDelete = 'false' ")
.list().asScala
}
