####Automatic POJO result mapping#### Select results can be mapped to POJOs automatically - based on object field name/db column name matching. Matching is case-insensitive and ignores '_' characters used particularly often in DB column names.
class Customer {
private Long id;
private Instant created;
private String name;
}
...
ObjectMappers objectMappers = ObjectMappers.builder().build();
...
// should be typically cached - eg as static - since it has some cost to instantiate
private static Mapper<Customer> customerMapper = objectMappers.forClass(Customer.class);
List customers = query.select("SELECT * FROM CUSTOMER").listResult(customerMapper); #####Requirements for the POJO#####
- Needs a no-arg constructor (can be private - since version 0.9.2).
- Fields can also be private / final, no need for accessor methods.
- Field types must be supported by FluentJdbc:
- jdbc-supported types
- java.time
- custom types
