Why is Retrofit GraphQL query failing with Unexpected character 'M' expected '}'? - java

I am attempting to execute GraphQL queries agains the SWAPI end point
https://api.graphcms.com/simple/v1/swapi
using Retrofit
My Retrofit API resembles
#Headers("Content-Type: application/json")
#POST("swapi")
Single<Response<String>> query(#Body final String query);
My Retrofit Services
public class StarWarsService extends BaseService implements StarWarsApi {
private static final String BASE_URL = "https://api.graphcms.com/simple/v1/";
private static final StarWarsApi INSTANCE = new StarWarsService();
/**
*
* #return
*/
public static StarWarsApi instance() {
return INSTANCE;
}
private final StarWarsApi service;
/**
*
*/
private StarWarsService() {
final Retrofit retrofit = new Retrofit.Builder().baseUrl(BASE_URL).client(okHttpClient)
.addCallAdapterFactory(Java8CallAdapterFactory.create())
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.addConverterFactory(ScalarsConverterFactory.create()).build();
service = retrofit.create(StarWarsApi.class);
}
#Override
public Single<Response<String>> query(String query) {
return service.query(query);
}
}
My main method
private static final String QUERY_STAR_WARS_0001 = "{ \"query\": \"{Starship(name:\"Millennium Falcon\") { name, hyperdriveRating, pilots(orderBy: height_DESC) { name, height, homeworld {name} } }}\" }";
public static void main(String[] args) {
StarWarsService.instance().query(QUERY_STAR_WARS_0001).subscribe();
}
I get the following logs

When I can execute the same query with an online GraphQL "browser" OK?
What error have I made in my code/approach?


Whatever code is producing the JSON object is not properly escaping " characters inside the json values.
{ "query": "{Starship(name:"Millennium Falcon") { name, hyperdriveRating, pilots(orderBy: height_DESC) { name, height, homeworld {name} } }}" }
should be
{ "query": "{Starship(name:\"Millennium Falcon\") { name, hyperdriveRating, pilots(orderBy: height_DESC) { name, height, homeworld {name} } }}" }

Spring REST noHandlerFound

I am creating simple REST API with spring mvc, but when I go to http://localhost:8080/fundnesia/api/loans I got noHandlerFound eror. Seems like spring doesnt register these #RestController, #RequestMapping and #PostMapping, #DeleteMapping annotations. Any help please
Here is my entity class
package com.fundnesia.entity;
import java.math.BigDecimal;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name="loan")
public class Loan {
#Id
#GeneratedValue(strategy =GenerationType.IDENTITY)
#Column(name="id")
private int id;
#Column(name="tenure")
private int tenure;
#Column(name="ticket_size")
private BigDecimal ticketSize;
#Column(name="fee")
private BigDecimal fee;
#Column(name="total_loan")
private BigDecimal totalLoan;
#Column(name="installment_per_month")
private BigDecimal installmentPerMonth;
#Column(name="status")
private String status;
public Loan() {
}
public Loan(int tenure, BigDecimal ticketSize, BigDecimal fee, BigDecimal totalLoan, BigDecimal installmentPerMonth,
String status) {
this.tenure = tenure;
this.ticketSize = ticketSize;
this.fee = fee;
this.totalLoan = totalLoan;
this.installmentPerMonth = installmentPerMonth;
this.status = status;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getTenure() {
return tenure;
}
public void setTenure(int tenure) {
this.tenure = tenure;
}
public BigDecimal getTicketSize() {
return ticketSize;
}
public void setTicketSize(BigDecimal ticketSize) {
this.ticketSize = ticketSize;
}
public BigDecimal getFee() {
return fee;
}
public void setFee(BigDecimal fee) {
this.fee = fee;
}
public BigDecimal getTotalLoan() {
return totalLoan;
}
public void setTotalLoan(BigDecimal totalLoan) {
this.totalLoan = totalLoan;
}
public BigDecimal getInstallmentPerMonth() {

}
public void setInstallmentPerMonth(BigDecimal installmentPerMonth) {
this.installmentPerMonth = installmentPerMonth;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
#Override
public String toString() {

JavaFX Observable list not updating GUI properly after being bound to listview [duplicate]

This question already has answers here:
JavaFX controller class not working

Javafx - Can application class be the controller class

Closed 5 years ago.
Issue:
After receiving a message from a the MessageListener class adds a message to a private final ObservableList<String> which in turn updates the GUI on change. the problem is that this happens inconsistently and for some unknown reason there seems to be 2 lists that interchange in adding the message to its list.
here is a log of this behavior:

If I mock the MessageListener class to just add a String every few seconds the log shows 2 lists that have the same size.

Using try-catch to skip exception causes falling into an infinite loop

I have this difficulty that for some URLs, the BufferedReader reaches a Connection timeout and throws an exception which interrupts the whole program. What I need is to either check the time that a connection is spending for opening and if it reaches a threshold, which must be less than of the one for timeout, it skips that URL to open a stream and then fetch the next URL or it handles a timeout in a way that does not cause the program to stop. Is there any idea how to do such?
URL url = new URL(line);
URLConnection connection = url.openConnection();
if (connection instanceof HttpURLConnection) {
HttpURLConnection httpConn = (HttpURLConnection) connection;
int statusCode = httpConn.getResponseCode();
if (statusCode <= 200 && statusCode < 300)
try{
BufferedReader brURL = new BufferedReader(new InputStreamReader(url.openStream()));
while((tempLine = brURL.readLine())!=null){
UrlMatcher=UrlPattern.matcher(tempLine);
java.util.logging.Logger.getLogger(SimpleCrawler.class.getName()).log(Level.SEVERE, tempLine);
if(UrlMatcher.find())
{
String resultURL=UrlMatcher.group();
fop.write(resultURL.toLowerCase().getBytes());
fop.write(System.getProperty("line.separator").getBytes());
System.out.println(resultURL);
}
}
}
catch(ConnectException ex){}
}

EDIT Using try-catch, now it falls into an infinite loop in some other part of execution.
EDIT 2
By adding a logger before if(UrlMatcher.find()), inside the while-loop, when it goes to the infinite loop, it shows the following log (I include the last match before the log for further clarity)

You should use setConnectTimeout and then catch SocketTimeoutException.
try {
HttpURLConnection con = (HttpURLConnection) new URL(url).openConnection();
con.setConnectTimeout(5000); //set timeout to 5 seconds
return (con.getResponseCode() == HttpURLConnection.HTTP_OK);
}
catch (java.net.SocketTimeoutException e) { return false; }
See documentation here.

The requested resource is not available- 404 - RESTful web service in Eclipse

I've been using the following guide to develop a hello world REST web service.
The guide can be found at: http://wiki.eclipse.org/Creating_a_JAX-RS_Web_Service
I'm trying to open the path: "http://localhost:8080/BeezerServer/jaxrs/addresses"
but it keeps on saying that "The requested resource (/BeezerServer/jaxrs/addresses) is not available."
my web.xml:
