public abstract class MappingSqlQuery<T> extends MappingSqlQueryWithParameters<T>
Reusable query in which concrete subclasses must implement the abstract mapRow(ResultSet, int) method to convert each row of the JDBC ResultSet into an object.Simplifies MappingSqlQueryWithParameters API by dropping parameters and context. Most subclasses won't care about parameters. If you don't use contextual information, subclass this instead of MappingSqlQueryWithParameters.

MappingSqlQuery
public MappingSqlQuery()
Constructor that allows use as a JavaBean.
MappingSqlQuery
public MappingSqlQuery(DataSource ds, String sql)

ds
- DataSource to use to obtain connectionssql
- SQL to run

mapRow
protected final T mapRow(ResultSet rs, int rowNum, Object[] parameters, Map<?,?> context) throws SQLException
This method is implemented to invoke the simpler mapRow template method, ignoring parameters.- 指定者:
mapRow
在类中MappingSqlQueryWithParameters<T>
- 参数:
rs
- ResultSet we're working throughrowNum
- row number (from 0) we're up toparameters
- to the query (passed to the execute() method). Subclasses are rarely interested in these. It can benull
if there are no parameters.context
- passed to the execute() method. It can benull
if no contextual information is need.- 返回:
- an object of the result type
- 抛出:
SQLException
- if there's an error extracting data. Subclasses can simply not catch SQLExceptions, relying on the framework to clean up.- 另请参阅:

mapRow
protected abstract T mapRow(ResultSet rs, int rowNum) throws SQLException
Subclasses must implement this method to convert each row of the ResultSet into an object of the result type.Subclasses of this class, as opposed to direct subclasses of MappingSqlQueryWithParameters, don't need to concern themselves with the parameters to the execute method of the query object.
