问题描述 投票：0回答：1
  1. 尝试通过netflix-dgs实现graphql api。
  2. 获取资源未找到错误。
  3. 下面分享代码片段

出现以下错误

This application has no explicit mapping for /error, so you are seeing this as a fallback.

资源下的schema.graphqls

type Query {

}

type Show {

    releaseYear: Int

@Slf4j
@DgsComponent

    private final List<Show> shows = List.of(
            new Show("Stranger Things", 2016),
            new Show("Ozark", 2017),
            new Show("The Crown", 2016),
            new Show("Dead to Me", 2019),
            new Show("Orange is the New Black", 2013)
    );

    @DgsQuery
    public List<Show> shows(@InputArgument String titleFilter) {
        if(titleFilter == null) {
            return shows;
        }

        return shows.stream().filter(s -> s.getTitle().contains(titleFilter)).collect(Collectors.toList());
    }
}

尝试在应用程序属性中添加以下属性

dgs.graphql.graphiql.enabled=true
dgs.graphql.graphiql.path=/graphiql
dgs.graphql.path=/graphql

无法找到为什么调度程序 servlet 无法加载 dgs 组件，无法找到我在这里缺少的内容

java spring-boot maven netflix-dgs

Springboot 版本 > 3.0 需要 6 以上的 graphql 平台依赖版本。

它适用于以下依赖项

<dependency>
                <groupId>com.netflix.graphql.dgs</groupId>
                <artifactId>graphql-dgs-platform-dependencies</artifactId>
                <!-- The DGS BOM/platform dependency. This is the only place you set version of DGS -->
                <version>8.2.0</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
