解析类型时不存在 BigDecimal
BigDecimal not present when resolving type
我处于“中间”Spring Boot 2.5.4 with graphql-java-16.2 通过一些 org.springframework.experimental/graphql-spring-boot-starter 依赖引入。 GraphQL Java 文档建议我可以在我的模式中使用 BigDecimal 一些东西：https://www.graphql-java.com/documentation/v16/scalars/

type TemplateLineItemAction {
type: String!

我尝试将 scalar BigDecimal 添加到 schema.graphqls 文件中，但没有成功；相同的堆栈跟踪。
pom.xml 就像...

请注意 graphql-spring-boot-starter 启动器来自 Spring (org.springframework.experimental/graphql-spring-boot-starter)，而不是 com.graphql-java/graphiql-spring-boot-starter，这是许多 google 结果指向我的地方。这真的不重要，BigDecimal 映射 应该 是 graphql-java-16.2 的函数。但是，谁知道呢？
那个首发带来了...

我可以看到它有一些 GraphQLScalarType...
public static final GraphQLScalarType GraphQLBigDecimal = GraphQLScalarType.newScalar()
.name("BigDecimal").description("Built-in java.math.BigDecimal").coercing(new GraphqlBigDecimalCoercing()).build();
... 以及它可能会在某天移动的一些弃用，但它现在在那里：https://github.com/graphql-java/graphql-java/blob/v16.2/src/main/java/graphql/Scalars.java#L108。我只是不知道如何使用它。
我必须在我的 schema.graphqls 文件或项目中做什么才能在我的 GraphQL 类型上使用 BigDecimal？
在pom.xml
中添加以下依赖
<dependency>
<groupId>com.graphql-java</groupId>
<artifactId>graphql-spring-boot-starter</artifactId>
<version>5.0.2</version>

<version>5.0.2</version>

//修正类型
type TemplateLineItemAction {
type: String!
quantity: BigDecimal
}
就是这样。我需要将它添加到 RuntimeWiringBuilderCustomizer 中...
@Component
public class BoaDataWiring implements RuntimeWiringBuilderCustomizer {
private final NowService nowService;
public BoaDataWiring(NowService nowService) {
this.nowService = nowService;
}
@Override
public void customize(RuntimeWiring.Builder builder) {
/*
* Declare the scalar here in the RuntimeWiring.Builder
* Note there remains some ugly deprecation warning...
*
* "The is a non standard scalar and is difficult for clients
* (such as browser and mobile code) to cope with the exact
* semantics. These will be removed in the future version and
* moved to another library."
*/
builder.scalar(Scalars.GraphQLBigDecimal); // <- This is what did it
builder.type("Query", wiring ->
wiring.dataFetcher("now", env -> nowService.now()));
}
}
2021-08-25更新：在https://docs.spring.io/spring-graphql/docs/1.0.0-SNAPSHOT/reference/html/#data-querydsl-customizations快照上Spring已将界面更改为RuntimeWiringConfigurer。它的工作原理几乎相同...
/**
* RuntimeWiring provides access to the RuntimeWiring.Builder.
*/
@Component
public class RuntimeWiring implements RuntimeWiringConfigurer {
private static final Logger LOG = LoggerFactory.getLogger(RuntimeWiring.class);
@Override
public void configure(graphql.schema.idl.RuntimeWiring.Builder builder) {
LOG.trace("configure( builder: {} )", builder);
builder.scalar(Scalars.GRAPHQL_DATE);
builder.scalar(Scalars.GRAPHQL_BIG_DECIMAL);
}
}
另请注意，1.0.0-SNAPSHOT 实际上确实带有 graphql-java v17，它确实删除了 Scalars.GraphQLBigDecimal，因此 Scalars.GRAPHQL_BIG_DECIMAL 是我自己的。

我尝试将 scalar BigDecimal 添加到 schema.graphqls 文件中，但没有成功；相同的堆栈跟踪。
pom.xml 就像...

<groupId>org.springframework.boot</groupId>

</dependency>
<dependency>
<groupId>org.springframework.experimental</groupId>
<artifactId>graphql-spring-boot-starter</artifactId>
<version>1.0.0-M1</version>
</dependency>
请注意 graphql-spring-boot-starter 启动器来自 Spring (org.springframework.experimental/graphql-spring-boot-starter)，而不是 com.graphql-java/graphiql-spring-boot-starter，这是许多 google 结果指向我的地方。这真的不重要，BigDecimal 映射 应该 是 graphql-java-16.2 的函数。但是，谁知道呢？
那个首发带来了...

我可以看到它有一些 GraphQLScalarType...
public static final GraphQLScalarType GraphQLBigDecimal = GraphQLScalarType.newScalar()
.name("BigDecimal").description("Built-in java.math.BigDecimal").coercing(new GraphqlBigDecimalCoercing()).build();
... 以及它可能会在某天移动的一些弃用，但它现在在那里：https://github.com/graphql-java/graphql-java/blob/v16.2/src/main/java/graphql/Scalars.java#L108。我只是不知道如何使用它。
我必须在我的 schema.graphqls 文件或项目中做什么才能在我的 GraphQL 类型上使用 BigDecimal？
在pom.xml
中添加以下依赖<dependency>
<groupId>com.graphql-java</groupId>
<artifactId>graphql-spring-boot-starter</artifactId>
<version>5.0.2</version>
</dependency>
<dependency>
<groupId>com.graphql-java</groupId>

<dependency>

<artifactId>graphiql-spring-boot-starter</artifactId>
<version>5.0.2</version>
</dependency>
//修正类型
type TemplateLineItemAction {
type: String!
quantity: BigDecimal
}
就是这样。我需要将它添加到 RuntimeWiringBuilderCustomizer 中...
@Component
public class BoaDataWiring implements RuntimeWiringBuilderCustomizer {
private final NowService nowService;
public BoaDataWiring(NowService nowService) {
this.nowService = nowService;
}
@Override
public void customize(RuntimeWiring.Builder builder) {
/*
* Declare the scalar here in the RuntimeWiring.Builder
* Note there remains some ugly deprecation warning...
*
* "The is a non standard scalar and is difficult for clients
* (such as browser and mobile code) to cope with the exact
* semantics. These will be removed in the future version and
* moved to another library."
*/
builder.scalar(Scalars.GraphQLBigDecimal); // <- This is what did it
builder.type("Query", wiring ->
wiring.dataFetcher("now", env -> nowService.now()));
}
}
2021-08-25更新：在https://docs.spring.io/spring-graphql/docs/1.0.0-SNAPSHOT/reference/html/#data-querydsl-customizations快照上Spring已将界面更改为RuntimeWiringConfigurer。它的工作原理几乎相同...
/**
* RuntimeWiring provides access to the RuntimeWiring.Builder.
*/
@Component
public class RuntimeWiring implements RuntimeWiringConfigurer {
private static final Logger LOG = LoggerFactory.getLogger(RuntimeWiring.class);
@Override
public void configure(graphql.schema.idl.RuntimeWiring.Builder builder) {
LOG.trace("configure( builder: {} )", builder);
builder.scalar(Scalars.GRAPHQL_DATE);
builder.scalar(Scalars.GRAPHQL_BIG_DECIMAL);
}
}
另请注意，1.0.0-SNAPSHOT 实际上确实带有 graphql-java v17，它确实删除了 Scalars.GraphQLBigDecimal，因此 Scalars.GRAPHQL_BIG_DECIMAL 是我自己的。
