SpringBoot2 配置 JOOQ MariaDB："required a bean of type 'javax.sql.DataSource' that could not be found"
SpringBoot2 Configuration JOOQ MariaDB: "required a bean of type 'javax.sql.DataSource' that could not be found"
这不是第一次被问了，我看了很多关于这个话题的文章，但我无法解决这个问题：
Field dataSource in de.foo.MariaDbConfig required a bean of type 'javax.sql.DataSource' that could not be found.
我所有的配置都和本文中的一样。代码生成与给定的 ddl sql 文件一起正常工作。数据库是 MariaDB。为什么这个错误一直出现？

我也这样定义了自己的DataSource，但是错误不断出现：
@Bean
public DataSource datasource() {
return DataSourceBuilder.create()
.driverClassName("org.mariadb.jdbc.Driver")
.url("jdbc:mariadb://localhost:3306/foo")
.username("root")
.password("foo123")
.build();
}
我希望你们中的一些人有想法。
所以 Simon Martinelli 通过在 Whosebug 中找到解决方案来帮助我。删除洞配置 class 后，我得到了这个“找不到 DSLContext”的错误。然后我发现了这个问题：
彻底解决了我的问题。很抱歉提出一个已经解决的问题，但没有指向 R2dbcAutoConfiguration 的方向。
所以，正如 Simon 所说，删除配置 class，并且正如这个问题的答案已经指出的那样，添加 @SpringBootApplication(exclude = { R2dbcAutoConfiguration.class }) 解决了问题。
