How to initialize a GraphQL Java project without using Spring Boot?

[khat33b]

All the GraphQL samples only use Spring Boot. I want to know how to use GraphQL without using Spring.I want to make a new GraphQL Java project but I do not want to use Spring Boot for it. I want to make the exact equivalent of this sample project but only using Jersey 3 and Jakarta 5. I have added my Gradle dependenices like this:

dependencies {
    implementation group: 'org.glassfish.jersey.containers', name: 'jersey-container-servlet', version: '3.0.3'
    implementation group: 'org.glassfish.jersey.inject', name: 'jersey-hk2', version: '3.0.3'
    implementation group: 'org.glassfish.jersey.media', name: 'jersey-media-moxy', version: '3.0.3'
    implementation group: 'jakarta.servlet', name: 'jakarta.servlet-api', version: '5.0.0'
    implementation group: 'jakarta.xml.bind', name: 'jakarta.xml.bind-api', version: '3.0.1'
    implementation group: 'com.sun.xml.bind', name: 'jaxb-impl', version: '3.0.2'
    
    implementation 'com.graphql-java:graphql-java:17.3'
    implementation 'com.graphql-java:graphql-java-extended-scalars:17.0'
    implementation 'com.graphql-java:graphql-java-extended-validation:17.0'
    implementation 'com.google.guava:guava:31.0.1-jre'
    
    implementation 'com.google.code.gson:gson:2.8.8'
}

I would like to know how to rewrite the BookDetailsApplication, GraphQLDataFetchers and GraphQLProvider classes using Jersey 3.

I dont have a lot of time to go into detauls right now but you can

• Have a single/graphql entry point in Jersey - one HTTP resource
• Have it create a GraphQL instance - this can be per request or you need to use your dependency IoC or statics to make this static one time only
• Create ExecutionInput from the Jersey ars
• Execute stuff with graphql.execute(executionInput)
