SpringBoot 未公开 GraphQL

Question

我有一个多模块项目，其中之一是 GraphQL 模块 可运行文件位于具有工作 RestController 的不同模块中 GraphQLController 未公开。 我尝试将 application.properties 移动到可运行模块不起作用，尝试移动 GraphQLController 也不起作用我什至将所有文件移动到可运行模块但没有任何反应。 我的依赖关系很好 我的 gradle 很好 我确信我的代码可以工作，但只能单独尝试，它确实有效，但我正在开发一个多模块项目，所以我不能单独运行它。 这里似乎有什么问题，我用谷歌搜索了这个问题并尝试了所有相关的解决方案
文件架构：

应用程序属性

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

Answer 1

我在让 Spring Graphql 在多模块项目中工作时也遇到问题。根据文档，架构位置配置必须像这样调整：

//application.properties
spring.graphql.schema.location=classpath*:graphql/**/

当我使用此配置启动应用程序时，我收到 UnsatisfiedDependencyException 并出现以下错误：

errors=['XY' type [@1:1] tried to redefine existing 'XY' type [@6887:1]

当我将架构文件移动到根项目时，子项目中的控制器不会被拾取。
