JdbcOperations (Spring Framework API 2.0) - Spring Framework 2.0.5 API 文档英文版

The Spring Framework

org.springframework.jdbc.core
Interface JdbcOperations

All Known Implementing Classes:
JdbcTemplate

public interface JdbcOperations

Interface specifying a basic set of JDBC operations. Implemented by JdbcTemplate. Not often used directly, but a useful option to enhance testability, as it can easily be mocked or stubbed.

Alternatively, the standard JDBC infrastructure can be mocked. However, mocking this interface constitutes significantly less work. As an alternative to a mock objects approach to testing data access code, consider the powerful integration testing support provided in the org.springframework.test package, shipped in spring-mock.jar.

Method Detail

execute

Object execute(ConnectionCallback action)
               throws DataAccessException
Execute a JDBC data access operation, implemented as callback action working on a JDBC Connection.

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

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

Parameters:
sql - SQL query to execute
Returns:
an List that contains a Map per row
Throws:
DataAccessException - if there is any problem executing the query
See Also:

Note that that, for the default implementation, JDBC RowSet support needs to be available at runtime: by default, Sun's com.sun.rowset.CachedRowSetImpl class is used, which is part of JDK 1.5+ and also available separately as part of Sun's JDBC RowSet Implementations download (rowset.jar).

Parameters:
sql - SQL query to execute
Returns:
a SqlRowSet representation (possibly a wrapper around a javax.sql.rowset.CachedRowSet)

update

int update(PreparedStatementCreator psc)
           throws DataAccessException
Issue an update using a PreparedStatementCreator to provide SQL and any required parameters.

A PreparedStatementCreator can either be implemented directly or configured through a PreparedStatementCreatorFactory.

Parameters:
psc - object that provides SQL and any necessary parameters
Returns:
the number of rows affected
Throws:
DataAccessException - if there is any problem issuing the update
See Also:
PreparedStatementCreatorFactory

update

int update(PreparedStatementCreator psc,
           KeyHolder generatedKeyHolder)
           throws DataAccessException
Issue an update using a PreparedStatementCreator to provide SQL and any required parameters. Generated keys will be put into the given KeyHolder.

Note that the given PreparedStatementCreator has to create a statement with activated extraction of generated keys (a JDBC 3.0 feature). This can either be done directly or through using a PreparedStatementCreatorFactory.

Parameters:
psc - object that provides SQL and any necessary parameters
generatedKeyHolder - KeyHolder that will hold the generated keys
Returns:
the number of rows affected
Throws:
DataAccessException - if there is any problem issuing the update

           throws DataAccessException
Issue an update using a PreparedStatementSetter to set bind parameters, with given SQL. Simpler than using a PreparedStatementCreator as this method will create the PreparedStatement: The PreparedStatementSetter just needs to set parameters.

Parameters:
sql - SQL containing bind parameters
pss - helper that sets bind parameters. If this is null we run an update with static SQL.
Returns:
the number of rows affected
Throws:
DataAccessException - if there is any problem issuing the update

                  throws DataAccessException
Issue multiple updates on a single PreparedStatement, using JDBC 2.0 batch updates and a BatchPreparedStatementSetter to set values.

Will fall back to separate updates on a single PreparedStatement if the JDBC driver does not support batch updates.

Parameters:
sql - defining PreparedStatement that will be reused. All statements in the batch will use the same SQL.
pss - object to set parameters on the PreparedStatement created by this method
Returns:
an array of the number of rows affected by each statement
Throws:

               CallableStatementCallback action)

Execute a JDBC data access operation, implemented as callback action working on a JDBC CallableStatement. This allows for implementing arbitrary data access operations on a single Statement, 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.

Parameters:
csc - object that can create a CallableStatement given a Connection
action - callback object that specifies the action
Returns:
a result object returned by the action, or null
Throws:
DataAccessException - if there is any problem

               CallableStatementCallback action)
               throws DataAccessException
Execute a JDBC data access operation, implemented as callback action working on a JDBC CallableStatement. This allows for implementing arbitrary data access operations on a single Statement, 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.

Parameters:
callString - the SQL call string to execute
action - callback object that specifies the action
Returns:
a result object returned by the action, or null
Throws:
DataAccessException - if there is any problem

call

Map call(CallableStatementCreator csc,
         List declaredParameters)
         throws DataAccessException
Execute a SQL call using a CallableStatementCreator to provide SQL and any required parameters.

Parameters:

declaredParameters - list of declared SqlParameter objects
Returns:
Map of extracted out parameters
Throws:
DataAccessException - if there is any problem issuing the update
