类 BeanPropertyRowMapper

java.lang.Object
  net.paoding.rose.jade.rowmapper.BeanPropertyRowMapper

所有已实现的接口：

org.springframework.jdbc.core.RowMapper

public class BeanPropertyRowMapper
extends Object
implements org.springframework.jdbc.core.RowMapper

RowMapper implementation that converts a row 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.

Column 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.

To facilitate mapping between columns and fields that don't have matching names, try using column aliases in the SQL statement like "select fname as first_name from customer".

Please note that this class is designed to provide convenience rather than high performance. For best performance consider using a custom RowMapper.
