    • GraphQLReactiveRequest

      public GraphQLReactiveRequest(String graphQLRequest) throws GraphQLRequestPreparationException
      Creates the GraphQL request, in reactive mode, for a full request. It will:
      • Read the query and/or the mutation
      • Read all fragment definitions
      • For all non scalar field, subfields (and so on recursively), if they are empty (that is the query doesn't define the requested fields of a non scalar field, then all its scalar fields are added)
      • Add the introspection __typename field to all scalar field list, if it doesnt't already exist. This is necessary to allow proper deserialization of interfaces and unions.

      This method will 'guess' the GraphQlClient to use, in order to execute the client. This means that, when using a GraphQL client that can attack several servers, you must use the relevant GraphQLRequest class, that is: the one generated in the relevant folder, along with the other classes for this schema.
      Parameters:
      schema - value of the springBeanSuffix plugin parameter for the searched schema. When there is only one schema, this plugin parameter is usually not set. In this case, its default value ("") is used.
      graphQLRequest - The GraphQL request, in text format, as defined in the GraphQL specifications, and as it can be used in GraphiQL. Please read the client doc page for more information, including hints and limitations.
      Throws:
      GraphQLRequestPreparationException

      public GraphQLReactiveRequest(org.springframework.graphql.client.GraphQlClient graphQlClient, String graphQLRequest, com.graphql_java_generator.annotation.RequestType requestType, String fieldName, InputParameter... inputParams) throws GraphQLRequestPreparationException
      Create the instance for the given GraphQL request, in reactive mode, for a partial request or a full request.
      Important note: this constructor SHOULD NOT be used only by the code generated by the plugin, not by external applications. Its signature may change in the future. To prepare Partial Requests, application code SHOULD call the getXxxxGraphQLRequests methods, that are generated in the query/mutation/subscription java classes.
      Parameters:
      graphQlClient - The GraphQlClient that is responsible for the actual execution of the request
      graphQLRequest - The partial GraphQL request, in text format. Writing partial request allows use to execute a query/mutation/subscription, and only define what's expected as a response for this query/mutation/subscription. You can send the parameters for this query/mutation/subscription as parameter of the java method, without dealing with bind variable in the GraphQL query. Please read the client doc page for more information, including hints and limitations.
      requestType - The information whether this queryName is actually a query, a mutation or a subscription
      fieldName - The name of the query, mutation or subscription, for instance "createHuman", in the GraphQL request "mutation {createHuman (...) { ...}}".
      inputParams - The list of input parameters for this query/mutation/subscription
      Throws:
      GraphQLRequestPreparationException

    • execQuery

      public reactor.core.publisher.Mono<Query> execQuery(Map<String,Object> parameters) throws GraphQLRequestExecutionException
      This method executes the current GraphQL request as a full query request. It offers a logging of the call (if in debug mode), or of the call and its parameters (if in trace mode).
      Here is a sample (and please have a look to the graphql-java-generator website for more information): 
       GraphQLRequest request;
 
 public void setup() {
   GraphQLRequest.setStaticConfiguration(...);
   // Preparation of the query
   request = myQueryType.getResponseBuilder()
                        .withQueryResponseDef("query{hero(param:?heroParam) @include(if:true) {id name @skip(if: ?skip) appearsIn friends {id name}}}").build();
 }
 
 public void doTheJob() {
   ..
   Map<String, Object> params = new HashMap<>();
   params.put("heroParam", heroParamValue);
   params.put("skip", Boolean.FALSE);

   Mono mono = request.execQuery(params);
   Query response = mono.block();
   ...
 }
      Parameters:
      parameters - The list of values, for the bind variables defined in the query. If there is no bind variable in the defined Query, this argument may be null or an empty Map
      Throws:

 ...
 }
      Type Parameters:
      T - The type that must is returned by the subscription in the GraphQL schema, which is actually the type that will be sent in each notification received from this subscription.
      Parameters:

      The Subscription client. It allows to stop the subscription, by executing its SubscriptionClient.unsubscribe() method. This will stop the incoming notification flow, and will free resources on both the client and the server.
      Throws:
      GraphQLRequestExecutionException - When an error occurs during the request execution, typically a network error, an error from the GraphQL server or if the server response can't be parsed
