I’m trying to read a record with JdbcClient.
One column should be converted to a custom type.
From the documentation and multiple web searches I understand I should create and register a Converter to accomplish this.
Unfortunately I always and up with the same org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.lang.String] to type [com.example.demo.DemoApplication$PersonName] exception.
How do I customize the ConversionService used by JdbcClient?
I know I can work around this problem by using a RowMapper but I’m trying to avoid it.
This is the code I’m running with java 17 and spring boot 3.3.0.
