我目前正在将现有的 Micronaut 应用程序从版本 1.2.x 升级到 2.2.1(最新),我认为开始使用它micronaut-data
来执行所需的任何数据库交互也是一个好主意。
我已经实现了所有各种代码更改,并且还移植了代码以使用 Micronaut 自己的存储库,但是每当我启动应用程序时,每次它尝试执行任何与数据库相关的交互时都会失败并出现以下错误:
20:21:06.535 [scheduled-executor-thread-21] ERROR i.m.s.DefaultTaskExceptionHandler - Error invoking scheduled task for bean [fts.marketing.utils.$TestDefinition$Intercepted@122b3da3] No bean of type [io.micronaut.transaction.SynchronousTransactionManager] exists. Make sure the bean is not disabled by bean requirements (enable trace logging for 'io.micronaut.context.condition' to check) and if the bean is enabled then ensure the class is declared a bean and annotation processing is enabled (for Java and Kotlin the 'micronaut-inject-java' dependency should be configured as an annotation processor).

我已按照此处找到的有关设置 Micronaut 数据的配置指南进行操作,并且我认为我已经导入了所有正确的依赖项https://micronaut-projects.github.io/micronaut-data/latest/guide/#introduction。
文档指出事务管理器应该自动可用,但情况似乎并非如此。
供参考build.gradle

有没有人暗示为什么会出现这个问题?
