The project is graphql client for java,support custom query and mutation.
The current version only supports post requests
You need java1.8 and maven.
Welcome to my home page:Mount Cloud
1:Support proxy setting.
2:Support subquery.
3:Support multiple query.
4:More flexible expansion.
Requested parameters support custom complex types and Enum types.

} catch (IOException e) {

}mutation is
mutation{
updateUser(id:1,name:"123",age:18){

}
}Mutation demo,The query is consistent with the mutation.

}该项目是java的graphql客户端，支持自定义query和mutation.
当前版本仅支持post请求
你需要java1.8和maven.
欢迎观临我的主页:Mount Cloud
1:支持代理服务器.
2:支持子查询.
3:支持多个查询组合.
4:更加灵活的扩展方式.
请求的参数支持自定义复杂类型和Enum类型。

}用Mutation做演示,query与mutation原理一样.
