下午好，面对这样的问题。玩过 GraphQL。我做了一个测试示例，并决定将其移至主项目。我什至不知道如何描述这个错误以及它为什么会弹出。如果有人遇到这样的事情，我会很高兴你的帮助！

java.lang.NoSuchMethodError: 'void graphql.ExecutionInput.<init>(java.lang.String, java.lang.String, java.lang.Object, java.lang.Object, java.util.Map)'

我没有任何想法。唯一可能是任何依赖项的行为都很奇怪，所以我附上了 pom.xml

文件 vehicleql.graphqls

type Vehicle {
    id: ID!,
    type: String,
    modelCode: String,
    brandName: String,
    launchDate: String
}

type Query {
    vehicles(count: Int):[Vehicle]
    vehiclesall:[Vehicle]
    vehicle(id: ID):Vehicle
}

type Mutation {
    createVehicle(type: String!, modelCode: String!, brandName: String, launchDate: String):Vehicle
}

和解析器

@Component
public class VehicleQuery implements GraphQLQueryResolver {

    @Autowired
    private VehicleService vehicleService;

    public List<Vehicle> getVehicles(final int count) {
        return this.vehicleService.getAllVehicles(count);
    }

    public List<Vehicle> getVehiclesall() {
        return this.vehicleService.getAllVehicles();
    }

    public Optional<Vehicle> getVehicle(final int id) {
        return this.vehicleService.getVehicle(id);
    }
}

标签： java spring-boot graphql

【解决方案1】：

我有 2 个依赖项。

<dependency>
  <groupId>com.graphql-java</groupId>
  <artifactId>graphql-java</artifactId>
  <version>14.0</version>
</dependency>

和

<dependency>
  <groupId>com.graphql-java</groupId>
  <artifactId>graphql-spring-boot-starter</artifactId>
  <version>5.0.2</version>
</dependency>

这两个依赖项并没有发誓，而是互相阻止了工作。当心。解决方案是删除 graphql-java 依赖
