Class BeanPropertyStructMapper

java.lang.Object
  org.springframework.data.jdbc.support.oracle.BeanPropertyStructMapper

All Implemented Interfaces:

StructMapper

public class BeanPropertyStructMapper
extends Object
implements StructMapper

Mapping implementation that converts struct attributes into a new instance of the specified mapped target class. The mapped target class must be a top-level class and it must have a default or no-arg constructor.

Attribute values are mapped based on matching the column name as obtained from result set metadata to public setters for the corresponding properties. The names are matched either directly or by transforming a name separating the parts with underscores to the same name using "camel" case.

Mapping is provided for fields in the target class for many common types, e.g.: String, boolean, Boolean, byte, Byte, short, Short, int, Integer, long, Long, float, Float, double, Double, BigDecimal, java.util.Date, etc.
