mapping

public Map<String,Object> mapping(ResultSet row,
                                  int currentRowIndex,
                                  ResultSetDescription resultSetDescription)

指定者:

mapping 在接口中 RowMapper<Map<String,Object>>

getColumnKey

protected String getColumnKey(String columnName)

Determine the key to use for the given column in the column Map.

参数:

columnName - the column name as returned by the ResultSet

返回:

the column key to use

另请参阅:

ResultSetMetaData.getColumnName(int)

getColumnValue

@Nullable
protected Object getColumnValue(ResultSet rs,
                                           int index)
                                    throws RuntimeException

Retrieve a JDBC object value for the specified column.

The default implementation uses the getObject method. Additionally, this implementation includes a "hack" to get around Oracle returning a non standard object for their TIMESTAMP datatype.

参数:

rs - is the ResultSet holding the data

index - is the column index

返回:

the Object returned

抛出:

RuntimeException

createColumnMap

protected Map<String,Object> createColumnMap(int columnCount)
