SimpleJdbcInsert is a Spring component. It defines a multi-threaded, reusable object providing easy insert capabilities for a table. It provides meta data processing to simplify the code needed to construct a basic insert statement.
A SimpleJdbcInsert is a multi-threaded, reusable object providing easy insert capabilities for a table. It provides meta data processing to simplify the code needed to construct a basic insert statement. All you need to provide is the name of the table and a Map containing the column names and the column values.
The meta data processing is based on the DatabaseMetaData provided by the JDBC driver. As long as the JBDC driver can provide the names of the columns for a specified table than we can rely on this auto-detection feature. If that is not the case then the column names must be specified explicitly.
The actual insert is being handled using Spring's JdbcTemplate
.
Many of the configuration methods return the current instance of the SimpleJdbcInsert to provide the ability to string multiple ones together in a "fluid" interface style.
Example Usage
public class JdbcActorDao implements ActorDao {
private SimpleJdbcTemplate simpleJdbcTemplate;
private SimpleJdbcInsert insertActor;
public void setDataSource(DataSource dataSource) {
this.simpleJdbcTemplate = new SimpleJdbcTemplate(dataSource);
this.insertActor =
new SimpleJdbcInsert(dataSource)
.withTableName("t_actor")
.usingGeneratedKeyColumns("id");
}
public void add(Actor actor) {
Map<String, Object> parameters = new HashMap<String, Object>();
parameters.put("first_name", actor.getFirstName());
parameters.put("last_name", actor.getLastName());
Number newId = insertActor.executeAndReturnKey(parameters);
actor.setId(newId.longValue());
}
// ... additional methods
}
