setRowMapper

public void setRowMapper(RowMapper<T> rowMapper)

Set a specific RowMapper instance to use for this query.

Since:

4.3.2

setRowMapperClass

public void setRowMapperClass(Class<? extends RowMapper> rowMapperClass)

Set a RowMapper class for this query, creating a fresh RowMapper instance per execution.

afterPropertiesSet

public void afterPropertiesSet()

Description copied from class: RdbmsOperation

Ensures compilation if used in a bean factory.

Specified by:

afterPropertiesSet in interface InitializingBean

Overrides:

afterPropertiesSet in class RdbmsOperation

newRowMapper

protected RowMapper<T> newRowMapper(@Nullable Object @Nullable [] parameters,
 @Nullable Map<?,?> context)

Description copied from class: SqlQuery

Subclasses must implement this method to extract an object per row, to be returned by the execute method as an aggregated List.

Specified by:

newRowMapper in class SqlQuery<T extends @Nullable Object>

Parameters:

parameters - the parameters to the execute() method, in case subclass is interested; may be null if there were no parameters.

context - the contextual information passed to the mapRow callback method. The JDBC operation itself doesn't rely on this parameter, but it can be useful for creating the objects of the result list.
