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
#PostMapping(value = "/Produits")
public ResponseEntity<Void> ajouterProduit(#RequestBody ProduitDTO produit) {
Produit produitCK = new Produit();
produitCK.setIdPM(new ProduitMagasin(produit.getId(), produit.getIdMagasin()));
produitCK.setDateAjout(produit.getDateAjout());
produitCK.setEtatProduit(produit.getEtatProduit());
produitCK.setIdReference(produit.getIdReference());
produitCK.setNumeroSerie(produit.getNumeroSerie());
produitCK.setPrixVente(produit.getPrixVente());
produitCK.setTVA(produit.getTVA());
produitCK.setType(produit.getType());
Produit produitAdded = produitDao.save(produitCK);
if (produitAdded == null)
return ResponseEntity.noContent().build();
else
return new ResponseEntity<>(HttpStatus.CREATED);

EDIT : the post method :
public static HttpResponse post(Object object, String type){
HttpResponse response=null;
try{
CloseableHttpClient client = HttpClientBuilder.create().build();
HttpPost postRequest = new HttpPost(getUrl(type));
System.out.println(getUrl(type));
ObjectMapper mapper= new ObjectMapper();
String jsonInString = mapper.writeValueAsString(object);
System.out.println(jsonInString);
StringEntity input = new StringEntity(jsonInString);
input.setContentType("application/json");
postRequest.setEntity(input);
response = client.execute(postRequest);
if (response.getStatusLine().getStatusCode() != 201) {
throw new RuntimeException("Failed : HTTP error code : "
+ response.getStatusLine().getStatusCode());
}
BufferedReader br = new BufferedReader(
new InputStreamReader((response.getEntity().getContent())));
String output;
System.out.println("Output from Server .... \n");
while ((output = br.readLine()) != null) {
System.out.println(output);
}
System.out.println(response.getStatusLine().getStatusCode()+" ");
client.close();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally{
return response;
}
EDIT 2 : the error on tomcat local :

Thanks tp billy frost what to do 2 things :
HttpPost postRequest = new HttpPost(getUrl(type));
postRequest.setHeader("Content-Type", "application/json;charset=UTF-8");
StringEntity input = new StringEntity(jsonInString, "UTF-8");

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();
}
I am parsing a JSON title, URL etc. from a PHP script. I want to give a reward with PHP script after the user click my link. Reward code -
String awr = Config.Base_Url+"videos/award.php";
Now everything is working, there is just no reward, no call to my PHP script...
How do i need modify my script to get correct reward? My java activity -

Thank you very much for helping!
Can you please let me know what went wrong in the below sample.
Employee.java
public class Employee {
private String name;
public String getName() {
return name;
}
public String getAge() {
return age;
}
private String age;
}
JsontoJava.java
import com.google.gson.Gson;
public class JsontoJava {
public static void main(String ar[]){
Gson gson = new Gson();
String json = "{\"Employee\":[{\"name\":\"Test\", \"age\":\"12\"}]}";
Employee staff = gson.fromJson(json, Employee.class);
System.out.println("Name : "+staff.getName());
}
}
Unfortunately getting the wrong output:
Name :null
Your json is not right. Change to this.
{"name":"Test","age":"12"}
I have a bean that implements JSObject ( & Map ) interface as shown below. I have removed some overridden methods to make it easy to read.

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
Called for thisvalueOf and returned:null

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)");
}
}
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);
