I want to copy properties from one object to another, both are of the same class. However it's not copying the fields. Here is the demo code:
public static void main(String[] args) throws Exception {
A from = new A();
A to = new A();
from.i = 123;
from.l = 321L;
System.out.println(from.toString());
System.out.println(to.toString());
BeanUtils.copyProperties(from, to);
System.out.println(from.toString());
System.out.println(to.toString());
}
public static class A {
public String s;
public Integer i;
public Long l;
#Override
public String toString() {
return "A{" +
"s=" + s +
", i=" + i +
", l=" + l +
'}';
}
}
And the output is:
A{s=null, i=123, l=321}
A{s=null, i=null, l=null}
A{s=null, i=123, l=321}
A{s=null, i=null, l=null}
Looks like I have to have setter/getters for the class:
public static void main(String[] args) throws Exception {
A from = new A();
A to = new A();
from.i = 123;
from.l = 321L;
System.out.println(from.toString());
System.out.println(to.toString());
BeanUtils.copyProperties(from, to);
System.out.println(from.toString());
System.out.println(to.toString());
}
public static class A {
public String s;
public Integer i;
public Long l;
public String getS() {
return s;
}
public void setS(String s) {
this.s = s;
}
public Integer getI() {
return i;
}
public void setI(Integer i) {
this.i = i;
}
public Long getL() {
return l;
}
public void setL(Long l) {
this.l = l;
}
#Override
public String toString() {
return "A{" +
"s=" + s +
", i=" + i +
", l=" + l +
'}';
}
}
Now the output is:
A{s=null, i=123, l=321}
A{s=null, i=null, l=null}
A{s=null, i=123, l=321}
A{s=null, i=123, l=321}

I want to Add same nuctk in every request in the body.
But request use the formData i can't convert this to object in interceptor.
My client
package com.example.demo.client;
import com.example.demo.config.NhanhPageFeignClientInterceptor;
import com.example.demo.request.CreateNhanhProductRequest;
import org.springframework.cloud.openfeign.FeignClient;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
#FeignClient(
value = "nhanhPage",
url = "https://nhanh.vn/product",
configuration = NhanhPageFeignClientInterceptor.class
)
public interface NhanhProductV1Client {
#PostMapping(value = "/item/add", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
String createProduct(#RequestBody CreateNhanhProductRequest request);
}
This is my interceptor
package com.example.demo.config;
import com.example.demo.request.CreateNhanhProductRequest;
import com.fasterxml.jackson.databind.ObjectMapper;
import feign.RequestInterceptor;
import feign.form.FormData;
import feign.form.FormEncoder;
import feign.form.spring.SpringFormEncoder;
import org.springframework.context.annotation.Bean;
import org.springframework.http.HttpHeaders;
import org.springframework.http.MediaType;
import org.springframework.util.LinkedMultiValueMap;
import org.springframework.util.MultiValueMap;
import java.io.IOException;
public class NhanhPageFeignClientInterceptor {
#Bean
public RequestInterceptor requestInterceptor() {
return requestTemplate -> {
String bodyTemplate = requestTemplate.bodyTemplate();
byte[] body = requestTemplate.body();
FormData formData = new FormData(MediaType.MULTIPART_FORM_DATA_VALUE, "data" , body);
requestTemplate.header(HttpHeaders.COOKIE, "Some cookie");
};
}
}
How to change the body in feign client interceptor.
Thank!
I have a Parcel Entity, and I am populating the fields through #PostMapping. The value Volume should be gotten from a method taking in values from the agruments in the constructor.
Controller Class:
#Controller
public class Controller {
#Value("#{${listOfBases}}")
private List<String> listOfBases;
#Value("#{${listOfDestinations}}")
private List<String> listOfDestinations;
#Autowired
ParcelRepository parcelRepository;
#GetMapping("/register_parcel")
public String showParcelRegistrationForm(Model model) {
Parcel parcel = new Parcel();
model.addAttribute("parcel", parcel);
model.addAttribute("listOfBases", listOfBases);
model.addAttribute("listOfDestinations", listOfDestinations);
return "parcel/register_form_parcel";
}
#PostMapping("register_parcel")
public String registerParcel(#ModelAttribute("parcel") Parcel parcel) {
System.out.println(parcel);
parcelRepository.save(parcel);
return "user/user_registration_success_form";
}
}
Parcel Class:
#Entity
public class Parcel {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
int id;
String length;
String width;
String height;
String weight;
String base;
String destination;
String creationDate;
String volume;
No args constructor:
public Parcel() {
creationDate = getCreationDateAndTime();
}
public Parcel(int id, String length, String width, String height, String weight, String base, String destination) {
this.id = id;
this.length = length;
this.width = width;
this.height = height;
this.weight = weight;
this.base = base;
this.destination = destination;
creationDate = getCreationDateAndTime();
volume = String.valueOf(calculateVolume(width, height, length));
}
Getters and Setters:
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getLength() {
return length;
}
public void setLength(String length) {
this.length = length;
}
public String getWidth() {
return width;
}
public void setWidth(String width) {
this.width = width;
}
public String getHeight() {
return height;
}
public void setHeight(String height) {
this.height = height;
}
public String getWeight() {
return weight;
}
public void setWeight(String weight) {
this.weight = weight;
}
public String getBase() {
return base;
}
public void setBase(String base) {
this.base = base;
}
public String getDestination() {
return destination;
}
public void setDestination(String destination) {
this.destination = destination;
}
public String getCreationDate() {
return creationDate;
}
public void setCreationDate(String creationDate) {
this.creationDate = creationDate;
}
public String getVolume() {
return volume;
}
public void setVolume(String volume) {
this.volume = volume;
}
private String getCreationDateAndTime() {
DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
LocalDateTime now = LocalDateTime.now();
return dtf.format(now);
}
CalculateVolume method that is the root of the problem:
private int calculateVolume(String width, String height, String length) {
int w = Integer.parseInt(width);
int h = Integer.parseInt(height);
int l = Integer.parseInt(length);
return w * h * l;
}
But the value volume is null in my database. Even System.out.println(); in calculateVolume does not print anything on the console, but when I run create an instance in main, all runs fine and dandy.
Any ideas on how I should proceed, or is my question too vague?
Thank you

Change Post method in your controller

to

I have list of tasks. When I delete my one of the task my list still shows that task in the list but on server side i have updated list I am not able to refresh my list. I am getting new task array from server but not able to show it. When I launched my app again then it is showing the updated list. How can I get updated list without killing the app? Both the times I have updated array but not able to show it on the view.

I think you need to add providerChangeSupport.fireProviderRefresh("res");
and you have to make public method for providerChangeSupport.
Here is the link : https://community.oracle.com/message/13203364#13203364
Other than the fix suggested by Rashi Verma, there is one more change required.
The code snippet:
res = (Response[]) res_new.toArray(new Response[res_new.size()]);
setRes(res);
needs to be changed to:
Response[] temp_res;
temp_res = (Response[]) res_new.toArray(new
Response[res_new.size()]);
setRes(temp_res);
Currently, because the value of res is changed before invoking setRes, the propertyChangeEvent is not fired inside setRes. Both this propertyChangeEvent and the providerRefresh are needed for the changes you are making to start reflecting on the UI.
No matter how simple I make the compareTo of my complex key, I don't get expected results. With the exception of if I use one key that is the same for every record, it will appropriately reduce to one record. I've also witnessed that this happens only when I process the full load, if I break off a few of the records that didn't reduce and run it on a much smaller scale those records get combined.
The sum of the output records is correct, but there is duplication at the record level of items I would have expected to group together. So where I would expect say 500 records summing up to 5,000, I end up with 1232 records summing up to 5,000 with obvious records that should have been reduced into one.
I've read about the problems with object references and complex keys and values, but I don't see anywhere that I have potential for that left. To that end you will find places that I'm creating new objects that I probably don't need to, but I'm trying everything at this point and will dial it back once it is working.
I'm out of ideas on what to try or where and how to poke to figure this out. Please help!

Your compareTo is flawed, it will totally fail the sort algorithm, because you seem to break transivity in your ordering.
I would recommend you to use a CompareToBuilder from Apache Commons or a ComparisonChain from Guava to make your comparisons much more readable (and correct!).
