My List<Object> is not being passed correctly as object of my ModelAndView

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}
</c:forEach>
This is my users class:
#Entity
#Table(name="usuario")
public class User implements Serializable {
#Id
#Column(name="id")
#GeneratedValue(strategy=GenerationType.IDENTITY)
private int id;
#JoinColumn(name = "id_perfil")
#OneToOne(cascade=CascadeType.ALL, fetch = FetchType.EAGER)
private Perfil perfil;
#Column(name="nombre")
private String nombre;
#Column(name="usuario")
private String usuario;
#Column(name="contrasenia")
private String contrasenia;
#Column(name="correo")
private String correo;
#Column(name="telefono")
private String telefono;
#Column(name="imagen_perfil")
private String imagen_perfil;
#Column(name="intento_fallido")
private int intento_fallido;
#Column(name="intranet_id")
private Integer intranet_id;
#Column(name="intranet_notaria")
private Integer intranet_notaria;
#Column(name="intranet_token_codigo")
private String intranet_token_codigo;
#Column(name="intranet_token_fecha")
#Temporal(TemporalType.TIMESTAMP)
private Date intranet_token_fecha;
#Column(name="tesoreria_token_codigo")
private String tesoreria_token_codigo;
#Column(name="tesoreria_token_fecha")
#Temporal(TemporalType.TIMESTAMP)
private Date tesoreria_token_fecha;
#Column(name="activo")
private int activo;
public int getId() { return id; }
public void setId(int id) { this.id = id; }
public Perfil getPerfil() { return perfil; }
public void setPerfil(Perfil perfil) { this.perfil = perfil; }

public String getTelefono() { return telefono; }
public void setTelefono(String telefono) { this.telefono = telefono; }
public String getImagenPerfil() { return imagen_perfil; }
public void setImagenPerfil(String imagen_perfil) { this.imagen_perfil = imagen_perfil; }
public int getIntentoFallido() { return intento_fallido; }
public void setIntentoFallido(int intento_fallido) { this.intento_fallido = intento_fallido; }
public Integer getIntranetId() { return intranet_id; }
public void setIntranetId(Integer intranet_id) { this.intranet_id = intranet_id; }
public Integer getIntranetNotaria() { return intranet_notaria; }
public void setIntranetNotaria(Integer intranet_notaria) { this.intranet_notaria = intranet_notaria; }
public String getIntranetTokenCodigo() { return intranet_token_codigo; }
public void setIntranetTokenCodigo(String intranet_token_codigo) { this.intranet_token_codigo = intranet_token_codigo; }
public Date getIntranetTokenFecha() { return intranet_token_fecha; }
public void setIntranetTokenFecha(Date intranet_token_fecha) { this.intranet_token_fecha = intranet_token_fecha; }
public String getTesoreriaTokenCodigo() { return tesoreria_token_codigo; }
public void setTesoreriaTokenCodigo(String tesoreria_token_codigo) { this.tesoreria_token_codigo = tesoreria_token_codigo; }
public Date getTesoreriaTokenFecha() { return tesoreria_token_fecha; }
public void setTesoreriaTokenFecha(Date tesoreria_token_fecha) { this.tesoreria_token_fecha = tesoreria_token_fecha; }
public int getActivo() { return activo; }
public void setActivo(int activo) { this.activo = activo; }
#Override
public String toString() {
return "Id:" + id + ", " + "Perfil:" + perfil.getNombre() + ", " + "Id_Perfil:" + perfil.getId() + ", " + "Nombre:" + nombre + ", " + "Usuario:" + usuario + ", " + "Correo:" + correo + ", " + "Teléfono:" + telefono + ", " + "Image_Perfil:" + imagen_perfil + ", " + "Intranet_Id:" + intranet_id + ", " + "Intranet_Notaria:" + intranet_notaria + ", " + "Activo:" + activo;
}
}
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().

what meaning this error "java.util.stream.ReferencePipeline$3 cannot be cast to org.springframework.data.domain.Page"

i want filter my task depend the work id
but when run my code i have this error
java.util.stream.ReferencePipeline$3 cannot be cast to org.springframework.data.domain.Page
how i can solve these
this is my component
my services here:
public Page<TaskDataDTO> findAll(String workOrderId,Pageable pageable) {
log.debug("Request to get all TaskData");
if(workOrderId!=null)
return (Page<TaskDataDTO>) taskDataRepository.findAll(pageable).stream().filter(x-> x.getWorkOrderId()==workOrderId).map(taskDataMapper::toDto);
else
return null;
}
and my Controller here :
#GetMapping("/task-data/{workOrderId}")
public ResponseEntity<List<TaskDataDTO>> getAllTaskData(#PathVariable String workOrderId,Pageable pageable) {
if(workOrderId!=null)
{
log.debug("REST request to get a page of TaskData");
Page<TaskDataDTO> page = taskDataService.findAll(workOrderId,pageable);
HttpHeaders headers = PaginationUtil.generatePaginationHttpHeaders(ServletUriComponentsBuilder.fromCurrentRequest(), page);
return ResponseEntity.ok().headers(headers).body(page.getContent());
}
else {
return null;
}
}

Thank you.

return (Page<TaskDataDTO>) taskDataRepository.findAll(pageable).stream().filter(x-> x.getWorkOrderId()==workOrderId).map(taskDataMapper::toDto);
The line above is missing a terminal operation to consume the stream. Try adding something like .collect(Collectors.toList())
Here's the package description for java.util.stream

Getting and putting Json into Pojo class

So I've made an app that should be able to search for an artist off the Spotify API. The response returns a 200 code. But the returned object is null. Meaning that either the response code should be 204 or that something is wrong with my class. The class is made with pojo and seems right.
I can't seem to figure out what is wrong.
Here are the code.

I have a problem about this row. Is there any way to limit those BulkList when we call this BulkList from Part.
#OrderBy("date DESC")
private List<Bulk> bulks = new ArrayList<>();
I mean like this
This is My Repo
public interface PartsRepo extends CrudRepository<Parts, Integer> {
Parts findPartsByBarCode(String barCode) throws Exception;
List<Parts> findPartsByPartNameContaining(String partName) throws Exception;
List<Parts> findPartsByPartNumberContaining(String partNumber) throws Exception;
Parts findPartsByPartNumber(String partNumber) throws Exception;
}
This is my Controller
#GetMapping(value = "/search")
public void searchParts(HttpServletRequest req) {
try {
return
Parts
p=partsService.searchParts(Integer.parseInt(req.getParameter("id")));
List<Bulk> bulkList=p.getBulks();
} catch (Exception e) {
e.printStackTrace();
return null;
}
}
I want to limit the bulkList results from the entity.. is there any way to do that..?
List<Bulk> bulkList=p.getBulks();
limit above list from the
#OrderBy("date DESC")
private List<Bulk> bulks = new ArrayList<>();

I want to limit the bulkList results from the entity. Is there any way to do that?

#OneToMany(mappedBy = "bulk", cascade=CascadeType.PERSIST, fetch=LAZY)
#BatchSize(size=5)
private List<Bulk> bulks = new ArrayList<>();
You can do this way

now i am using below rest service request to add master data with child
{"description":"Placements","value":"Placements","url":"/Placements","instituteInfoDetails":[{"value":"Test"}]}
Code to save data
#Override
public void addInstituteInfoMaster(com.zertones.model.common.InstituteInfoMatster instituteInfoMatster)
{
Session session = sessionFactory.getCurrentSession();
session.saveOrUpdate(instituteInfoMatster);
}
but while saving it gives me below error
org.hibernate.PropertyValueException: not-null property references a null or transient value : com.zertones.model.common.InstituteInfoDetails.instituteInfotMaster
I searched and did as per solutions i added the cascade type information, but it did not helped.

create bidirectional Setter method for set InstituteInfoMatster to instituteInfoDetails
change class InstituteInfoMatster
public void setInstituteInfoDetails(List<InstituteInfoDetails> instituteInfoDetails)
{
for(InstituteInfoDetails ins : instituteInfoDetails){
ins.setComListMaster(this);
}
this.instituteInfoDetails = instituteInfoDetails;
}

I think you have a typo in this code:
#ManyToOne
#JoinColumn(name = "LIST_ID", nullable = false)
#JsonProperty("instituteInfotMaster")
#JsonBackReference
private InstituteInfoMatster instituteInfotMaster;
Shouldn't it be instituteInfoMaster instead?
EDIT: or maybe not, I can se you have multiple typos there, such as InstituteInfoMatster etc. Still, I think it would worth to fix these typos while you still can (if you still can, of course).
