getValueBySetterParameterType

public Object getValueBySetterParameterType(ResultSet resultSet,
                                            int column,
                                            Class<?> setterParameterType)
                                     throws SQLException

インタフェースからコピーされた説明: ResultSetConverter

Reads a column from the current row in the provided ResultSet and returns an instance of the specified Java Class containing the values read. This method is mainly used for "SEARCH SQL AND READ TO POJO". i.e. Convert from Sql to Java by the specified class. This method is used while converting ResultSet rows to objects. The class type is the field type in the target bean. null's will be respected for any non-native types. This means that if a field is of type Integer it will be able to receive a null value from the ResultSet; on the other hand, if a field is of type int it will receive 0 for a null value from the ResultSet.

定義:

getValueBySetterParameterType インタフェース内 ResultSetConverter

パラメータ:

resultSet - ResultSet (positioned in the row to be processed)

column - column index in the result set (starting with 1)

setterParameterType - Class of the object to be returned

例外:

SQLException

getValueBySqlType

protected Object getValueBySqlType(ResultSet resultSet,
                                   int column,
                                   int sqlType)
                            throws SQLException

Reads a column from the current row in the provided ResultSet and returns an instance of the specified Java SQLType containing the values read. This method is mainly used for "SEARCH SQL AND READ TO MAP". i.e. Convert from SQL to Java by the SQL type. This method is used while converting ResultSet rows to Map.
