Class SqlMapClientTemplate

java.lang.Object
  extended by org.springframework.jdbc.support.JdbcAccessor
      extended by org.springframework.orm.ibatis.SqlMapClientTemplate
All Implemented Interfaces:
InitializingBean, SqlMapClientOperations

public class SqlMapClientTemplate
extends JdbcAccessor
implements SqlMapClientOperations

Helper class that simplifies data access via the iBATIS SqlMapClient API, converting checked SQLExceptions into unchecked DataAccessExceptions, following the org.springframework.dao exception hierarchy. Uses the same SQLExceptionTranslator mechanism as JdbcTemplate.

The main method of this class executes a callback that implements a data access action. Furthermore, this class provides numerous convenience methods that mirror SqlMapExecutor's execution methods.

It is generally recommended to use the convenience methods on this template for plain query/insert/update/delete operations. However, for more complex operations like batch updates, a custom SqlMapClientCallback must be implemented, usually as anonymous inner class. For example:

 getSqlMapClientTemplate().execute(new SqlMapClientCallback() {
         public Object doInSqlMapClient(SqlMapExecutor executor) throws SQLException {
                 executor.startBatch();
                 executor.update("insertSomething", "myParamValue");
                 executor.update("insertSomethingElse", "myOtherParamValue");
                 executor.executeBatch();
                 return null;
         }
 });
The template needs a SqlMapClient to work on, passed in via the "sqlMapClient" property. A Spring context typically uses a SqlMapClientFactoryBean to build the SqlMapClient. The template an additionally be configured with a DataSource for fetching Connections, although this is not necessary if a DataSource is specified for the SqlMapClient itself (typically through SqlMapClientFactoryBean's "dataSource" property).
