春季启动升级从2.6.6到2.7.1 -dev.miku：r2dbc -mysql
我将Spring Boot从2.6.6升级到2.7.1，并运行到R2DBC-MYSQL错误中。
使用Spring Boot 2.6.6，我正在使用R2DBC-MYSQL。
runtimeOnly 'dev.miku:r2dbc-mysql'
将Spring Boot升级到2.7.1之后，会出现汇编错误。
因此，从build.gradle中评论了上述内容，并在运行时获得下面的错误。

尝试使用
实现组：'dev.miku'，名称：'r2dbc-mysql'，版本：'0.8.2.release'而不是runtime> runtimeonly'dev.miku：r2dbc-mysql''，我遇到了同样的问题，对我有用。Try with
implementation group: 'dev.miku', name: 'r2dbc-mysql', version: '0.8.2.RELEASE'instead ofruntimeOnly 'dev.miku:r2dbc-mysql', I had the same issue and it worked for me.用户1578872。
作为
io.asyncer的维护者：r2dbc-mysql，我想通知您，您所面临的问题的根本原因是Spring Boot 2.7.1使用R2DBC-SPI ：0.9.1.Release，而dev.miku：r2dbc-mysql：0.8.2支持R2DBC-SPI：0.8。*。我建议您切换到使用io.asyncer：r2dbc-mysql：0.9.2，它支持r2dbc-spi：0.9.1.release，是<代码> dev.miku：r2dbc-mysql 。以下是当前兼容性表
2.6 -mysql 基础戴上您当前的春季启动版。
有关更多信息，您可以通过。如果您还有其他问题或遇到任何问题，请随时在存储库中创建问题。我们在这里为您提供帮助！
