                                                 java.lang.Class<?> requiredType)
```
    Retrieve a JDBC column value from a ResultSet, using the specified value type.
    Uses the specifically typed ResultSet accessor methods, falling back to getResultSetValue(java.sql.ResultSet, int) for unknown types.
    Note that the returned value may not be assignable to the specified required type, in case of an unknown type. Calling code needs to deal with this case appropriately, e.g. throwing a corresponding exception.
    
    参数:
    
    rs - is the ResultSet holding the data
    
    index - is the column index
    
    requiredType - the required value type (may be null)
    
    返回:
    
    the value object
  - getResultSetValue
```
public static java.lang.Object getResultSetValue(java.sql.ResultSet rs,
                                                 int index)
```
    Retrieve a JDBC column value from a ResultSet, using the most appropriate value type. The returned value should be a detached value object, not having any ties to the active ResultSet: in particular, it should not be a Blob or Clob object but rather a byte array respectively String representation.
    Uses the getObject(index) method, but includes additional "hacks" to get around Oracle 10g returning a non-standard object for its TIMESTAMP datatype and a java.sql.Date for DATE columns leaving out the time portion: These columns will explicitly be extracted as standard java.sql.Timestamp object.
    
    参数:
    
    rs - is the ResultSet holding the data
    
    index - is the column index
    
    返回:
    
    the value object

                                                int columnIndex)
```
    Determine the column name to use. The column name is determined based on a lookup using ResultSetMetaData.
    This method implementation takes into account recent clarifications expressed in the JDBC 4.0 specification:
    columnLabel - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column.
    
    参数:
    
    resultSetMetaData - the current meta data to use
    
    columnIndex - the index of the column for the look up
    
    返回:
    
    the column name to use
