This may help you
Place jsonschema file on project root directory or in resource and read schema using normal file read and store it in variable say str

     booleab isValidRequest=false;
     String     requestData; // data to validate
     String str; //schema 

            JsonNode requestDataJsonNode = com.github.fge.jackson.JsonLoader.fromString(requestData);       
            final JsonNode schemaNode = JsonLoader.fromString(str);
           final JsonNode schemaNode=JsonLoader.fromResource("/jsonschema.json"); // for your query
            final JsonSchemaFactory factory = JsonSchemaFactory.byDefault();
            JsonValidator validator = factory.getValidator();        
            ProcessingReport processingReport=  validator.validate(schemaNode, requestDataJsonNode); 
            if(processingReport!=null)
            {
                isValidRequest=processingReport.isSuccess();
            }
            
            } catch (Exception e) {
                
            }
