public class JdbcTemplate
extends JdbcAccessor
implements JdbcOperations

This is the central class in the JDBC core package. It simplifies the use of JDBC and helps to avoid common errors. It executes core JDBC workflow, leaving application code to provide SQL and extract results. This class executes SQL queries or updates, initiating iteration over ResultSets and catching JDBC exceptions and translating them to the generic, more informative exception hierarchy defined in the org.springframework.dao package.

Code using this class need only implement callback interfaces, giving them a clearly defined contract. The PreparedStatementCreator callback interface creates a prepared statement given a Connection, providing SQL and any necessary parameters. The ResultSetExtractor interface extracts values from a ResultSet. See also PreparedStatementSetter and RowMapper for two popular alternative callback interfaces.

Can be used within a service implementation via direct instantiation with a DataSource reference, or get prepared in an application context and given to services as bean reference. Note: The DataSource should always be configured as a bean in the application context, in the first case given to the service directly, in the second case to the prepared template.

Because this class is parameterizable by the callback interfaces and the SQLExceptionTranslator interface, there should be no need to subclass it.

All SQL operations performed by this class are logged at debug level, using "org.springframework.jdbc.core.JdbcTemplate" as log category.

Constructor Detail

JdbcTemplate

public JdbcTemplate()
Construct a new JdbcTemplate for bean usage.

Note: The DataSource has to be set before using the instance.

See Also:
JdbcAccessor.setDataSource(javax.sql.DataSource)

JdbcTemplate

public JdbcTemplate(javax.sql.DataSource dataSource)
Construct a new JdbcTemplate, given a DataSource to obtain connections from.

Note: This will not trigger initialization of the exception translator.

Parameters:
dataSource - the JDBC DataSource to obtain connections from

JdbcTemplate

public JdbcTemplate(javax.sql.DataSource dataSource,
                    boolean lazyInit)
Construct a new JdbcTemplate, given a DataSource to obtain connections from.

Note: Depending on the "lazyInit" flag, initialization of the exception translator will be triggered.

Parameters:
dataSource - the JDBC DataSource to obtain connections from
lazyInit - whether to lazily initialize the SQLExceptionTranslator
Method Detail

setNativeJdbcExtractor

public void setNativeJdbcExtractor(NativeJdbcExtractor extractor)
Set a NativeJdbcExtractor to extract native JDBC objects from wrapped handles. Useful if native Statement and/or ResultSet handles are expected for casting to database-specific implementation classes, but a connection pool that wraps JDBC objects is used (note: any pool will return wrapped Connections).


getNativeJdbcExtractor

public NativeJdbcExtractor getNativeJdbcExtractor()
Return the current NativeJdbcExtractor implementation.


setIgnoreWarnings

public void setIgnoreWarnings(boolean ignoreWarnings)
Set whether or not we want to ignore SQLWarnings.

Default is "true", swallowing and logging all warnings. Switch this flag to "false" to make the JdbcTemplate throw a SQLWarningException instead.

See Also:
SQLWarning, SQLWarningException, handleWarnings(java.sql.Statement)

isIgnoreWarnings

public boolean isIgnoreWarnings()
Return whether or not we ignore SQLWarnings.


setFetchSize

public void setFetchSize(int fetchSize)
Set the fetch size for this JdbcTemplate. This is important for processing large result sets: Setting this higher than the default value will increase processing speed at the cost of memory consumption; setting this lower can avoid transferring row data that will never be read by the application.

Default is 0, indicating to use the JDBC driver's default.

See Also:
Statement.setFetchSize(int)

getFetchSize

public int getFetchSize()
Return the fetch size specified for this JdbcTemplate.


setMaxRows

public void setMaxRows(int maxRows)
Set the maximum number of rows for this JdbcTemplate. This is important for processing subsets of large result sets, avoiding to read and hold the entire result set in the database or in the JDBC driver if we're never interested in the entire result in the first place (for example, when performing searches that might return a large number of matches).

Default is 0, indicating to use the JDBC driver's default.

See Also:
Statement.setMaxRows(int)

getMaxRows

public int getMaxRows()
Return the maximum number of rows specified for this JdbcTemplate.


setQueryTimeout

public void setQueryTimeout(int queryTimeout)
Set the query timeout for statements that this JdbcTemplate executes.

Default is 0, indicating to use the JDBC driver's default.

Note: Any timeout specified here will be overridden by the remaining transaction timeout when executing within a transaction that has a timeout specified at the transaction level.

See Also:
Statement.setQueryTimeout(int)

getQueryTimeout

public int getQueryTimeout()
Return the query timeout for statements that this JdbcTemplate executes.


setSkipResultsProcessing

public void setSkipResultsProcessing(boolean skipResultsProcessing)
Set whether results processing should be skipped. Can be used to optimize callable statement processing when we know that no results are being passed back - the processing of out parameter will still take place. This can be used to avoid a bug in some older Oracle JDBC drivers like 10.1.0.2.


isSkipResultsProcessing

public boolean isSkipResultsProcessing()
Return whether results processing should be skipped.


setSkipUndeclaredResults

public void setSkipUndeclaredResults(boolean skipUndeclaredResults)
Set whether undelared results should be skipped.


isSkipUndeclaredResults

public boolean isSkipUndeclaredResults()
Return whether undeclared results should be skipped.


setResultsMapCaseInsensitive

public void setResultsMapCaseInsensitive(boolean resultsMapCaseInsensitive)
Set whether execution of a CallableStatement will return the results in a Map that uses case insensitive names for the parameters.


isResultsMapCaseInsensitive

public boolean isResultsMapCaseInsensitive()
Return whether execution of a CallableStatement will return the results in a Map that uses case insensitive names for the parameters.


execute

public <T> T execute(ConnectionCallback<T> action)
          throws DataAccessException
Description copied from interface: JdbcOperations
Execute a JDBC data access operation, implemented as callback action working on a JDBC Connection. This allows for implementing arbitrary data access operations, within Spring's managed JDBC environment: that is, participating in Spring-managed transactions and converting JDBC SQLExceptions into Spring's DataAccessException hierarchy.

The callback action can return a result object, for example a domain object or a collection of domain objects.

Specified by:
execute in interface JdbcOperations
Parameters:
action - the callback object that specifies the action
Returns:
a result object returned by the action, or null
Throws:
DataAccessException - if there is any problem

createConnectionProxy

protected java.sql.Connection createConnectionProxy(java.sql.Connection con)
Create a close-suppressing proxy for the given JDBC Connection. Called by the execute method.

The proxy also prepares returned JDBC Statements, applying statement settings such as fetch size, max rows, and query timeout.

Parameters:
con - the JDBC Connection to create a proxy for
Returns:
the Connection proxy
See Also:
Connection.close(), execute(ConnectionCallback), applyStatementSettings(java.sql.Statement)

execute

public <T> T execute(StatementCallback<T> action)

The callback action can return a result object, for example a domain object or a collection of domain objects.

Specified by:
execute in interface JdbcOperations
Parameters:
action - callback object that specifies the action
Returns:
a result object returned by the action, or null
Throws:
DataAccessException - if there is any problem

Specified by:
queryForMap in interface JdbcOperations
Parameters:
sql - SQL query to execute
Returns:
the result Map (one entry for each column, using the column name as the key)
Throws:
IncorrectResultSizeDataAccessException - if the query does not return exactly one row
DataAccessException - if there is any problem executing the query
