I've already tried to change the name of SocietyBlockFloor.societyBlockFloorId, but then in the ON clause it still uses (society.societyId = societyBlockFloor.societyId) where societyBlockFloor.societyId doesn't exist.
you have a repeated column in the mapping. You mapped the same database column twice. you have:
#Id
#Column(name="society_id")
private String societyBlockFloorId;
And
#ManyToOne
#JoinColumn(name = "society_id", nullable = false)
private SocietyDetails societyDetails;
This seems useless
#Id
#Column(name="society_id")
private String societyBlockFloorId;
If you want societyid just ask to societyDetails.getId();
And this on the manyToOne side
referencedColumnName = "society_id"

In my Spring Controller I have:
List<User> Users = this.userService.UsersList();
mav = new ModelAndView("users");
mav.addObject("Users", Users);
When I iterate over Users I can see all the attributes values of every element of my list.
This is my .jsp code:
<c:forEach items="${Users}" var="usr">
${usr}

}
The problem is that ${usr} is only displaying some of my attributes, but not all! I need to display all the attributes in my jsp.
Try using camelCase notation if you are not doing so. For example instead of ${usr.imagen_perfil} use ${usr.imagenPerfil}. I think it will be expecting to use the object getters getImagenPerfil().
I have two table entity channel and channel_stats.I want to save data in tables using session.save().
channel_stats can contain duplicate entry with duplicate channel ID.
Can you please tell me how to do so using secondary table annotation in hibernate. or is there any other way? i tried with embedded and embedded annotation bit looks like its for same table

}
}
As I understand the question, #Embeddable is not what you want in this case. #Embeddable and #Embedded is used when you don't want a separate second table. Since you want a separate table to have the ChannelStat data, it seems like you are trying to create a #OneToMany relationship where one Channel object can have multiple ChannelStat objects.
So your Channel class should have
#OneToMany( mappedBy = "channel", cascade = CascadeType.ALL )
private List<ChannelStat> channelStat;
Instead of
#Embedded
private ChannelStats channelStats;
And your ChannelStat class should have
public class ChannelStats {
// Other variables and their getters and setters
#ManyToOne( cascade = CascadeType.ALL )
#JoinColumn( name = "id" )
private Channel channel;
}

Also have created Interface classes for each table. extending JpaRepository
I am able to retrieve data by searching in hcgapplicationcategory table
with the Dao interface object for hcgapplicationcategory table and using .
categorydao.findAll();
categorydao.findById(1);
I want to search data by the link_name in hcgapplicationlinks table and get the parent details as well. I want to avoid writing query and retrieve using just JPA functionalities.
I need to search a link_name and get app_id,link_id,link_name,link_page,app_name,app_folder, category_name (Other fields may or may not be needed.). How can this be done?

My bad, it was just a silly mistake. SOItemDetails table was not getting created because #GeneratedValue is not applicable for String type, it should be of int type. Now need to do below change in SOItemDetails Entity Class.
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
#Column(name = "SO_ITEM_DTLS_ID", unique = true, nullable = false, length = 100)
int soItemDtlsRecordNo;
I m new to Springs, Hibernate and REST API.
How can i catch org.hibernate.exception.ConstraintViolationException ( I do not want to delete the mill data since you have dependent(child) data on the mill and display a appropriate msg to user that it cannot delete it due to orders exists for the mill.
Please Help.
Thank you
Here is my Code.

millRepository.delete(id);
log.debug(" ", id);
return ResponseEntity.ok().headers(HeaderUtil.createEntityDeletionAlert("mill", id.toString())).build();
}
CrudRepository
void delete(ID id);

Basically you have to handle the Exception. Introduce a try catch block and output the appropriate message.
Handle the exception at the base level and funnel it to the controller.
