mapRow

public com.alibaba.fastjson.JSONObject mapRow(ResultSet rs,
                                              int rowNum)
                                       throws SQLException

指定者:

mapRow 在接口中 org.springframework.jdbc.core.RowMapper<com.alibaba.fastjson.JSONObject>

抛出:

SQLException

createColumnMap

protected com.alibaba.fastjson.JSONObject createColumnMap(int columnCount)

Create a Map instance to be used as column map.

By default, a linked case-insensitive Map will be created.

参数:

columnCount - the column count, to be used as initial capacity for the Map

返回:

the new Map instance

另请参阅:

LinkedCaseInsensitiveMap

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 SQLException

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:

SQLException
