GraphQL.execute介绍

[英]Executes the graphql query using the provided input object builder
[中]使用提供的输入对象生成器执行graphql查询

代码示例

代码示例来源：origin: graphql-java/graphql-java

/**
 * Executes the graphql query using the provided input object builder
 *
 * @param executionInputBuilder {@link ExecutionInput.Builder}
 *
 * @return an {@link ExecutionResult} which can include errors
 */
public ExecutionResult execute(ExecutionInput.Builder executionInputBuilder) {

代码示例来源：origin: graphql-java/graphql-java

private void equivalentSerialAndAsyncQueryExecution() throws Exception {
  //::FigureC
  ExecutionResult executionResult = graphQL.execute(executionInput);
  // the above is equivalent to the following code (in long hand)
  CompletableFuture<ExecutionResult> promise = graphQL.executeAsync(executionInput);
  ExecutionResult executionResult2 = promise.join();
  //::/FigureC
}
