我剛開始使用vaadin。我目前正在使用 H2 資料庫，但是當我想創建資料庫“上傳”時出現錯誤：
org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL "create table upload (id varchar(255) not null, file_name varchar(255) not null, import_date bigint not null, month varchar(255) not null, year varchar(255) not null, primary key (id))" via JDBC Statement

我在教程中創建了專用于上傳表的存盤庫和服務類。
uj5u.com熱心網友回復：
MONTH 和 YEAR 是 H2 和 SQL 標準中的保留關鍵字。
您必須重命名屬性或僅重命名帶有@Column注釋的列。
