How to fix this and other errors: Failed to convert from type [java.lang.String] to type [java.lang.Long] for value 'list'?

I'm implementing an example of a book on Spring Boot , but after executing, when trying to access the /clientes/list or /clientes/view route in the browser the following errors appear:

  

Failed to convert value of type 'java.lang.String' to required type   'com.greendog.models.Customer'; nested exception is   org.springframework.core.convert.ConversionFailedException: Failed to   convert from type [java.lang.String] to type [java.lang.Long] for   value 'list'; nested exception is java.lang.NumberFormatException: For   input string: "list"
