How to define array property using jsinterop?

How to define array property using jsinterop? - javascript

I am trying to define a javascript type using JsInterop but could not figure out how to define an array propery inside a type.
#JsType
public interface Task
{
// this works
#JsProperty String getTitle();
#JsProperty void setTitle(String title);
}
#JsType
public interface ViewModelInterface
{
// the following works
#JsProperty String getValue();
#JsProperty void setValue(String val);
// this does not work
#JsProperty Task[] getTasks();
#JsProperty void setTasks(Task[] tasks);
}
Is there any special syntax I should use?
Update:
I have come up with a temporary solution to the problem. I tried to use JNSI together with JsInterop and because the type define is javascript type we can add any property in that type after it is initialized.
The code is here
public class ViewModel implements ViewModelInterface
{
private String value;
public ViewModel()
{
value = "";
initTasksArray();
}
public String getValue() { return value; }
public void setValue(String val) { this.value = val; }
private native void initTasksArray()
/*-{
this.tasks =
[
{ title: 'Get high enough to grab the flag' },
{ title: 'Find the Princess' }
];
}*-/;
}
This way, the tasks property can be accessed from javascript as if it is defined as a #JsProperty. This is only a temporary solution and I am sure there will be a more proper one when JsInterop formally come out.

It should work as described.
Here is an example:
#JsType
public interface Task {
#JsProperty
String getTitle();
#JsProperty
void setTitle(String title);
public static Task getTask(String title) {
return new Task() {
private String title;
#Override
public String getTitle() {
return title;
}
#Override
public void setTitle(String title) {
this.title = title;
}
};
}
}
and
#JsType
public interface ViewModel {
#JsProperty
Task[] getTasks();
#JsProperty
void setTasks(Task[] tasks);
public static ViewModel getModel() {
return new ViewModel() {
Task[] tasks;
#Override
public void setTasks(Task[] tasks) {
this.tasks = tasks;
}
#Override
public Task[] getTasks() {
return tasks;
}
};
}
}
and the Javascript:
var model = ViewModel.getModel();
model.tasks = [Task.getTask('title1'), Task.getTask('title2')];
alert(model.tasks);

How to change the property of a specific object when buttonclick occurs, using a PUT-method (JSON) in react and springboot

I have made some code inside of the spring boot back-end application which allows me to change a property of a specific object, this property which needs to be changed is the "status" property:
#Entity
public class Pakketje {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
private int code;
private String status = "In magazijn";
public Pakketje() {
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getCode() {
return code;
}
public void setCode(int code) {
this.code = code;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
}
To change the property of that object, i will need to state the ID of that object (i think) inside of the react frontend application, and then fetch the PUT-method.
I will show you the method to change the property inside of my spring boot back-end application, this method can be found in the 'Service' class. 'bestaandPakketje' means existing pakketje.
#Override
public Pakketje getPakketjeById(int id) {
return pakketjeRepository.findById(id).orElse(null);
}
#Override
public Pakketje statusOnderweg(Pakketje pakketje) {
Pakketje bestaandPakketje = pakketjeRepository.findById(pakketje.getId()).orElse(null);
bestaandPakketje.setStatus(pakketje.getStatus());
return pakketjeRepository.save(bestaandPakketje);
}
}
And here is the controller:
public class PakketjeController {
#SuppressWarnings("SpringJavaInjectionPointsAutowiringInspection")
#Autowired
private PakketjeService pakketjeService;
#PostMapping("/add")
public String add(#RequestBody Pakketje pakketje) {
pakketjeService.pakketjeOpslaan(pakketje);
return "Pakketje opgeslagen!";
}
#GetMapping("/getAll")
public List<Pakketje> getAllePakketjes(){
return pakketjeService.getAllePakketjes();
}
#GetMapping("/getById/{id}")
public Pakketje findPakketjeById(int id) {
return pakketjeService.getPakketjeById(id);
}
#PutMapping("/updateOnderweg")
public Pakketje statusIsOnderweg(#RequestBody Pakketje pakketje) {
return pakketjeService.statusOnderweg(pakketje);
}
}
Now the next step is verry hard for me. Each 'pakketje' has his own button which can be clicked to change the property (I will upload the picture so please check it). When that button is clicked the property automatically should change from "In magazijn "to "onderweg".
I would appreciate some help!

How can I get a data from Spring-Security principal?

Now I face with some problems about principal data. Maybe it sounds like a fool. But I'm new to Spring..
I wanted to get some specific data from principal data, but it occured an error, So I cant.
this is my customUserDetails that implement UserDetails.
private String id;
private String pw;
private String name;
private String auth;
private String level;
private String label;
private int enabled;
#Override
public Collection<? extends GrantedAuthority> getAuthorities() {
ArrayList<GrantedAuthority> authList = new ArrayList<GrantedAuthority>();
authList.add(new SimpleGrantedAuthority(auth));
return authList;
}
#Override
public String getPassword() {
return pw;
}
#Override
public String getUsername() {
return id;
}
#Override
public boolean isAccountNonExpired() {
return true;
}
#Override
public boolean isAccountNonLocked() {
return true;
}
#Override
public boolean isCredentialsNonExpired() {
return true;
}
#Override
public boolean isEnabled() {
return enabled==1?true:false;
}
public String getName() {
return name;
}
public String getLabel() { return label;} // 4월 19일 동현 추가
public void setName(String name) {
this.name = name;
}
public String getAuth() {
return auth;
}
And this is principal data I got from console.log
CustomUserDetails(id=admin, pw=$2a$10$Z9C0gTGV0weknBvNi4YFY.l41vjrYo4UgO3MlPwgmIn4uDeYlepFq, name=Admin, auth=ROLE_ADMIN, level=null, label=N, enabled=1)
I want to extract label value from Principal, so I tried to do this code, but I can't.
console.log('${sessionScope.SPRING_SECURITY_CONTEXT.authentication.principal.label}');
How can I get 'label' data from principal?
Thank you for your kind support :)

In your Controller or any other bean, autowire user details like
public String doSomething(#AuthenticationPrincipal CustomUserDetails userDetails) {
String label = userDetails.getLabel();
}

Spring boot jpa can't insert row with string containing accents

I can"t understand the problem because i found nowhere the same problem.
i tried to insert product with type "pièces détachées". On the browser path /Produits the product doesn't show up but when i remove the accents from the string it's inserting in the mysql db. I tried to insert accents in the db the query is ok. But with my code it's impossible to do the same. here's a sample of my code for Produit :
//ajouter un produit

produitCK.setNumeroSerie(produit.getNumeroSerie());
produitCK.setPrixVente(produit.getPrixVente());
produitCK.setTVA(produit.getTVA());

StringEntity input = new StringEntity(jsonInString, "UTF-8");

Nashorn runtime exception while printing JSObject implementations

I have a bean that implements JSObject ( & Map ) interface as shown below. I have removed some overridden methods to make it easy to read.
package test.nashorn;
import java.util.Collection;
import java.util.HashMap;
import java.util.Map;
import java.util.Set;
import jdk.nashorn.api.scripting.JSObject;
public class JSBean implements JSObject, Map<String,Object>{
/**
* The current values for this object.
*/
private HashMap<String, Object> values = new HashMap<>();
#Override
public String toString() {
System.out.println("ToString");
Set<Entry<String,Object>> entries = values.entrySet();
StringBuilder sb = new StringBuilder();
for(Entry<String,Object> entry:entries){
sb.append(entry.getKey()+ " "+(String)entry.getValue());
}
System.out.println("Completed ToString");
return sb.toString();
}
#Override
public boolean hasMember(String name) {
return has(name);
}
// get the value of that named property
#Override
public Object getMember(String name) {
return get(name);
}
// get the value of that named property
#Override
public void setMember(String name,Object value) {
put(name,value);
}
public Object get(String name) {
System.out.println("JAVA Get is called."+name);
System.out.println("Called for this"+name+" and returned"
+":"+values.get(name));
return values.get(name);
}
#Override
public Object put(String name, Object value) {
System.out.println("JAVA Put is called. Input name: " + name + "\n Input values: " + value);
return values.put(name, value);
}
public boolean has(String name) {
System.out.println("JAVA Has is called. Input name: " + name);
return values.containsKey(name);
}
public JSBean() {
// TODO Auto-generated constructor stub
}
#Override
public Object call(Object arg0, Object... arg1) {
// TODO Auto-generated method stub
return null;
}
#Override
public Object eval(String arg0) {
// TODO Auto-generated method stub
return null;
}
#Override
public String getClassName() {
// TODO Auto-generated method stub
return null;
}
#Override
public Object getSlot(int arg0) {
// TODO Auto-generated method stub
return null;
}
#Override
public boolean hasSlot(int arg0) {
// TODO Auto-generated method stub
return false;
}
#Override
public boolean isArray() {

return false;
}
#Override

}
#Override
public boolean isInstance(Object arg0) {
// TODO Auto-generated method stub
return false;

#Override
public boolean isInstanceOf(Object arg0) {
// TODO Auto-generated method stub
return false;
}
#Override
public boolean isStrictFunction() {
// TODO Auto-generated method stub
return false;
}
}
When i run the test shown below
#Test
public void testDefaultValMethod(){
JSBean bean = new JSBean();
bean.setMember("hello", " Sport ");
//Add stuff to engine.
engine.put("jsBean", bean);
String source = "(function(){\n"
+ "print(jsBean);"
+ "} )();";
Object obj=null;
try {
obj = engine.eval(source);
} catch (ScriptException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("Returned : " + String.valueOf(obj));
}
I see the below error in the console. Ideally Nashorn should have directly called the toString() method of the bean to get the String implementation. Not sure what is going wrong here. I did try adding a call to 'toString()' explicitly in the getMember() method call but that did not fix the problem.
JAVA Put is called. Input name: hello
Input values: Sport
JAVA Get is called.toString
Called for thistoString and returned:null
JAVA Get is called.valueOf

print or "toString" conversions from scripts call "toString" method on the script object. Any property access (including function valued property) on a JSObject is routed to getMember method. So, to make "valueOf" or "toString" you've to implement appropriate getMember in your JSObject subtype.
Example:
import jdk.nashorn.api.scripting.*;
import javax.script.*;
public class Main {
static class MyJSObject extends AbstractJSObject {
#Override
public Object getMember(String name) {
if (name.equals("toString")) {
// return a "function" object for "toString" property
return new AbstractJSObject() {
#Override
public boolean isFunction() {
return true;
}
#Override
public Object call(Object self, Object...args) {
return self.toString();
}
};
}
return null; // other properties here
}
#Override
public String toString() {
return "my js object";
}
}
public static void main(String[] a) throws Exception {
ScriptEngineManager m = new ScriptEngineManager();
ScriptEngine e = m.getEngineByName("nashorn");
e.put("myObj", new MyJSObject());
e.eval("print(myObj)");
}
}
Alternatively, you can also override
Object getDefaultValue(final Class<?> hint) throws UnsupportedOperationException
method in your AbstractJSObject subclass.
import jdk.nashorn.api.scripting.*;
import javax.script.*;
public class Main2 {
static class MyJSObject extends AbstractJSObject {
#Override
public Object getDefaultValue(Class<?> hint) {
if (hint == String.class) {
return toString();
}
throw new UnsupportedOperationException("no conversion for " + hint);
}
#Override
public String toString() {
return "my js object";
}
}
public static void main(String[] a) throws Exception {
ScriptEngineManager m = new ScriptEngineManager();
ScriptEngine e = m.getEngineByName("nashorn");
e.put("myObj", new MyJSObject());
e.eval("print(myObj)");
}
}

Alert messages from controller: Add alert behavior in partial view?

In MVC 4, you could install this package Twitter.bootstrap.mvc and this would add lots of HTML helpers.
Once istalled you could send alert to view right from controller.
For example:
public class AccountController : BaseController
{
public ActionResult AlertExample()
{
Success("This is a success alert");
Error("This is error alert");
Information("This is information alert");
...
etc.
}
}
This would send the success alert right from controller to the view.
Objective: Sending Growl Messages from controller
I've tried to implement same thing from the project I mentioned.
So, this is what I've added to my project.
Base controller that other controller derives from
public class BaseController : Controller
{
//
// GET: /Base/
public void Warning(string message)
{
TempData.Add(Alerts.WARNING, message);
}
public void Success(string message)
{
TempData.Add(Alerts.SUCCESS, message);
}
public void Information(string message)
{
TempData.Add(Alerts.INFORMATION, message);
}
public void Error(string message)
{
TempData.Add(Alerts.ERROR, message);
}
}

and the _alert partial View
#using BootstrapSupport
#if (TempData.ContainsKey(Alerts.WARNING))
{
<div class="alert alert-block">
<a class="close" data-dismiss="alert" href="#">x</a>
<h4 class="toast-title">Attention!</h4>
#TempData[Alerts.WARNING]
</div>
}
#foreach (string key in Alerts.ALL.Except(new[] { Alerts.WARNING }))
{
if (TempData.ContainsKey(key))
{
<div class="toast toast-top-full-width toast-key">
<button type="button" class="toast-close-button" data-dismiss="alert">x</button>
#TempData[key]
</div>
}
}
After all this I can send alert messages right from controller:
And it works!
For example
public ActionResult Test()
{
Success("Person was successfully added to your addressbook");
}
above code would result this in view
but it is just displaying as content block. Not as I expected to work, as it just appears in view, no effect, nothing. I wanted it to work as in this site Toastr.
I'm guessing I have to implement javascript somewhere in my _alert view and get the message and type(success, error,...) and then use javascript to growl it, to make it behave it as it should.
But i don't have much knowledge about it.
Something like below? Thats just idea, because of my lack of knowledge of Javascript and jquery i couldn't make it work
#*if (TempData.ContainsKey(key))
{
<div class="toastMessageHolder" style="display: none">
<div class="toastMessage">#TempData[key]</div>
<div class="toastMessageType">#key</div>
</div>
if($(".toastMessageHolder"))
{
//loop all toastMessageHolders
$(".toastMessageHolder").foreach(function(){
var message = $(".toastMessage", this).html();
var messageType = $(".toastMessageType", this).html();
});
//feed this parameters to javascript
}*#
Could somebody help me how to make my growling from controller behave as mentioned in example of Toastr?
If I had to growl from any normal view if I hadn't implemented sending msgs from controller to view this is how I would do using toastr:
function foo(response) {
if (response.SomeTest) {
toastr.error(response.ErrorMessage, "Error");
}
else {
$(#Html.IdFor(m=>m.abc)).val('');
}
};
Asp.Net MVC version: 5.1.1
Growling package used: Toastr

This is what I ended up doing.
_alert view(partial). To send alert messages right from controller.
#using BootstrapSupport
<script>
toastr.options = {
closeButton: true,
debug: false,
positionClass: "toast-top-full-width",
onclick: null,
showDuration: "300",
hideDuration: "1000",
timeOut: "5000",
extendedTimeOut: "1000",
showEasing: "swing",
hideEasing: "linear",
showMethod: "fadeIn",
hideMethod: "fadeOut"
}
</script>
#if (TempData.ContainsKey(Alerts.SUCCESS))
{
foreach (var value in TempData.Values)
{
<script>
toastr.success("#value.ToString()");
</script>
}
TempData.Remove(Alerts.SUCCESS);
}
#if (TempData.ContainsKey(Alerts.ERROR))
{
foreach (var value in TempData.Values)
{
<script>
toastr.error("#value.ToString()");
</script>
}
TempData.Remove(Alerts.ERROR);
}
#if (TempData.ContainsKey(Alerts.INFORMATION))
{
foreach (var value in TempData.Values)
{
<script>
toastr.warning("#value.ToString()");
</script>
}
TempData.Remove(Alerts.INFORMATION);
}
#if (TempData.ContainsKey(Alerts.WARNING))
{
foreach (var value in TempData.Values)
{
<script>
toastr.warning("#value.ToString()");
</script>
}
TempData.Remove(Alerts.WARNING);
}
