Spring GraphQL 不填充记录类

问题描述 投票：0回答：1

我正在使用 Spring Boot GraphQL 构建 midia 跟踪器，但是当我尝试发送突变来创建用户时，会抛出流动错误：

因为当调用 registerUser() 时调试 UserInput 为 null 时，我对 GraphQL 做的错误不会填充 UserInput？有人能帮助我吗？ 如果您需要更多信息，请告诉我。

要求：

mutation User {
  registerUser(
    user: {
      username: "Biga",
      email: "[email protected]",
      password: "test"
    }
  ) {
    username
  }
}

用户.graphqls：

type Query {
    findUserByUsername(username: String!): User
    findUserById(id: ID!): User
    findUserByEmail(email: String!): User
}

type Mutation {
    registerUser(user: UserInput!): User
}

type User {
    id: ID
    username: String
    email: String
}

input UserInput {
    username: String!
    email: String!
    password: String!
}

用户输入.java

package com.espacogeek.geek.inputs;

public record UserInput(String username, String email, String password) {}

用户控制器.java

package com.espacogeek.geek.controllers;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.graphql.data.method.annotation.Argument;
import org.springframework.graphql.data.method.annotation.MutationMapping;
import org.springframework.stereotype.Controller;

import com.espacogeek.geek.inputs.UserInput;
import com.espacogeek.geek.modals.UserModal;
import com.espacogeek.geek.services.User.UserService;

import at.favre.lib.crypto.bcrypt.BCrypt;

@Controller
public class UserController {
    @Autowired
    private UserService userService;

    //Some codes...

    @MutationMapping
    public UserModal registerUser(@Argument UserInput userInput) {
        var passwordCrypted = BCrypt.withDefaults().hash(12, userInput.password().toCharArray());
        UserModal user = new UserModal(null, userInput.username(), userInput.email(), passwordCrypted);
        return userService.save(user);
    }
}

我通过将 

name
参数添加到 
@Argument
注释来解决此错误。我还将记录更改为类并添加了 get Getter 和 Setter。

要求：

mutation User {
    registerUser(newUser: {username: "BigaArtz", email: "[email protected]", password: "biga123"}){
        username
    }
}

graphql：

type Mutation {
    registerUser(newUser: NewUser): User
}

input NewUser {
    username: String!
    email: String!
    password: String!
}

NewUser.java

@Getter
@Setter
public class NewUser implements Serializable {
    private String username;
    private String email;
    private String password;
}

用户控制器.java

@Controller
public class UserController {
    @Autowired
    private UserService userService;

    @QueryMapping
    public Optional<UserModal> findUser(@Argument(name = "filter") UserInput userInput) {
        return userService.findByUsernameContains(userInput.getUsername());
    }

    @MutationMapping
    public UserModal registerUser(@Argument(name = "newUser") NewUser newUser) {
        var passwordCrypted = BCrypt.withDefaults().hash(12, newUser.getPassword().toCharArray());
        UserModal user = new UserModal(null, newUser.getUsername(), newUser.getEmail(), passwordCrypted);
        return userService.save(user);
    }
}
