[FIXED] How to convert object to query string in Java?

Issue

I am trying to convert the following object to query string, so that can be used with GET request.

Class A {
  String prop1;
  String prop2;
  Date date1;
  Date date2;
  ClassB objB;
}

Class B {
 String prop3;
 String prop4;
}

We can do that first object to Map then convert map to MultiValueMap and use URIComponentsBuilder.fromHttpUrl("httpL//example.com").queryParams(multiValueMap).build();

Is there shorter and better way of converting object to query string so that be used with GET request in Spring Project for Junit Test?

Solution

Why convert to Map then MultiValueMap, instead of just building it directly?

DateFormat dateFmt = new SimpleDateFormat("whatever date format you want");
URIComponentsBuilder.fromHttpUrl("httpL//example.com")
                    .queryParam("prop1", a.prop1)
                    .queryParam("prop2", a.prop2)
                    .queryParam("date1", dateFmt.format(a.date1))
                    .queryParam("date2", dateFmt.format(a.date2))
                    .queryParam("prop3", a.objB.prop3)
                    .queryParam("prop4", a.objB.prop4)
                    .build();
