How to automatically generate JsonPath for extractValueAsObject method by generateClient of graphqlcodegen

[Rudy0530]

Thank you for providing a great open source for graphql. I have a question while using it.

My project uses graphqlcodegen-maven-plugin to generate graphql client code.

Programming language is java.

Relevant dependencies are as follows.

        <dependency>
            <groupId>com.netflix.graphql.dgs.codegen</groupId>
            <artifactId>graphql-dgs-codegen-client-core</artifactId>
            <version>5.1.17</version>
        </dependency>
        <dependency>
            <groupId>com.netflix.graphql.dgs</groupId>
            <artifactId>graphql-dgs-client</artifactId>
            <version>5.5.1</version>
        </dependency>



        <plugin>
               <groupId>io.github.deweyjose</groupId>
                <artifactId>graphqlcodegen-maven-plugin</artifactId>
                <version>1.29</version>
                <configuration>
                    <schemaPaths>
                        <param>src/main/resources/schema</param>
                    </schemaPaths>
                    <generateClient>true</generateClient>
                    <maxProjectionDepth>4</maxProjectionDepth>
                    <javaGenerateAllConstructor>true</javaGenerateAllConstructor>
                    <packageName>packageName</packageName>
                    <subPackageNameClient>client</subPackageNameClient>
                    <subPackageNameDatafetchers>datafetchers</subPackageNameDatafetchers>
                    <subPackageNameTypes>types</subPackageNameTypes>
                    <typeMapping>
                        <Long>java.lang.Long</Long>
                    </typeMapping>
                </configuration>
        </plugin>

When extracting the returned value information from the graphql client interface, the extractValueAsObject method of the GraphQLResponse object is used to extract the data.

The implementation method is as follows:

GraphQLResponse graphQLResponse = apiService.queryUnBlock(graphQLQueryRequest);

var res= graphQLResponse .extractValueAsObject(new ABCGraphQLQuery().getOperationName(), Parent.class);

As we all know, the extractValueAsObject method supports two data extraction methods:

method	description	example
extractValueAsObject	Extract values given a JsonPath and deserialize into the given class	Ticks ticks = response.extractValueAsObject("ticks", Ticks.class)
extractValueAsObject	Extract values given a JsonPath and deserialize into the given TypeRef. Useful for Maps and Lists of a certain class.	List<Route> routes = response.extractValueAsObject("ticks.edges[*].node.route", new TypeRef<List<Route>>(){})

---

My current problems:

How to dynamically construct the first JsonPath parameter of extractValueAsObject through the code generated by graphqlcodegen-maven-plugin?

I need to construct parameters such as "submitReview. edges [*]. node. submittedBy" to directly extract the return value.

Thank you very much for your patience.
