Spring 統合ストア プロシージャ コーヒーの例を PostgreSQL から Oracle に複製しようとしています。成功せずに。元のコードへのリンクは 次のとおりですhttps://github.com/SpringSource/spring-integration-samples/tree/master/intermediate/stored-procedures-postgresql
すべてのコーヒーを取得する手順から始めることにしたので、プロジェクト内の名前による getCoffee への参照をすべて削除します。
これが私のストア プロシージャのコードです。
create or replace
PROCEDURE find_all_coffee_beverages AS
begin
for x in (SELECT id, coffee_name,
coffee_description
FROM coffee_beverages
ORDER BY ID) loop
dbms_output.put_line
(x.coffee_description);
end loop;
end;
これが私の春のコンテキストです：

だから私はそれをコンパイルして、次のようにmavenで実行します: mvn clean package exec:java -e 完全にコンパイルされますが、実行しようとすると次の例外が発生します:

なぜその例外が発生するのか誰かが知っていますか? 前もって感謝します。
