问题 I am looking to pass a field value to a resolved field using another object type. Another way to put it if I have `Customer > User > Profile' - how can I pass the CustomerID field value that would be in customer to Profile as an argument or variable in order to resolve correctly? 回答1: There's exactly 5 possibilities (as of graphql-java v12) to provide info to a resolver ( DataFetcher ) at any level: 1) Directly pass them in the query (possibly on multiple levels): {customer(id: 3) { user {

问题 I am new to GrapQL. I am trying to use it with spring boot. I can make query successfully, it is returning the data that I need, but i want now to use mutation.

问题 Is it possible to dynamically create a GraphQL schema ? We store the data in mongoDB and there is a possibility of new fields getting added. We do not want any code change to happen for this newly added field in the mongoDB document. Is there any way we can generate the schema dynamically ? Schema is defined in code, but for java(schema as pojo), when new attribute is added, you have to update and recompile code, then archive and deploy the jar again. Any way to generate schema by the data

问题 I am exploring GraphQL and would like to know if there is any way of renaming the response field for example i have a POJO with these field class POJO { Long id; String name; } GraphQL query: type POJO { id: Long name: String } My response is something like this { "POJO" { "id": 123, "name": "abc" } } Can i rename the name field to something like userName so that my response is below { "POJO" { "id": 123, "userName": "abc" } } 回答1: You can use GraphQL Aliases to modify individual keys in the

问题 It seems that the names defined in the .graphqls file MUST match the field names in the POJO. Is there a way to maybe annotate the field so that they don't have to? For example, I have something like this in the graphqls file type Person { personId: ID! name: String! } Then in my Entity POJO I have like @Id @Column(name="PERSON_ID") @JsonProperty("person_id") private int personId; @Column(name="NAME") @JsonProperty("name") private String name; So, the intention is for the field name to be

问题 Any webservice which supports GraphQL is consumable through a Java implementation? Because "it provides an alternative to REST..."? 回答1: Graphql-java (that you linked to) is an implementation of the GraphQL specification. As such, it is used to create GraphQL servers . A client doesn't need anything special to consume a service, just like it doesn't need anything special to consume a REST service - only to be be able to speak HTTP. You can use any generic HTTP client you like . Still, you

问题 I'm using Spring & graphql-java ( graphql-java-annotation ) in my project. For retrieving data part, i'm using a DataFetcher to get data from a service (from database). The weird thing is that: myService is always null . Anyone know the reason? DataFetcher @Component public class MyDataFetcher implements DataFetcher { // get data from database @Autowired private MyService myService; @Override public Object get(DataFetchingEnvironment environment) { return myService.getData(); } } Schema

问题 I’m working on a spring boot project with GraphQL. I'm using graphql-java-tools and graphql-spring-boot-starter. I managed to configure security and session management with spring security as you can see in the java config files below. Now the “/graphql” path is secured (it can be accessed only sending the “basic http authentication” or a session token ( x-auth-token ) in a http header of the request). Authenticating with “basic http authentication” on any GraphQL operation will start a new

问题 I'm new to Spring boot + GraphQL. I need to get the Query/Mutation operation name inside my controller class. Purpose : Need to grand permission to some users to specific mutation/Query operations. Here the user type will be passed as a request header and will be validated and check whether the user is allowed to access that operation. @PostMapping public ResponseEntity<Object> callGraphQLService(@RequestBody String query, @RequestHeader("user") String userName) { ExecutionResult result =
