Calling function using NamedParameterJdbcTemplate:

final String query = "select MY_FUNCTION(:arg1, :arg2, :arg3) from dual";
Map argMap = new HashMap<>();
argMap.put("arg1", "value1");
argMap.put("arg2", 2);
argMap.put("arg3", "value3");
final String result = new NamedParameterJdbcTemplate(dataSource)
        .queryForObject(query, argMap, String.class);

Calling procedure using JdbcTemplate:

final String query = "call MY_PROCEDURE(?, ?, ?)";
final Object[] args = {"arg1", "arg2", "arg3"};
new JdbcTemplate(dataSource).execute(query, args, String.class);

Calling function using SimpleJdbcCall:

final String result = new SimpleJdbcCall(dataSource)
        .withCatalogName("MY_PACKAGE")
        .withFunctionName("MY_FUNCTION")
        .executeFunction(String.class, "arg1", "arg2");

Calling procedure using SimpleJdbcCall:

new SimpleJdbcCall(dataSource)
        .withCatalogName("MY_PACKAGE")
        .withProcedureName("MY_PROCEDURE")
        .execute("arg1", arg2);
