このエラーが発生しても、それを修正する方法は見つけられません。列に対して、org.digitalcorpse.pirates.Pirate： は用タイプを決定できませんでした[org.hibernate.mapping.Column（海賊）]

Answer 1

あなたはこの @Table（名前= "my_pirate_table"）

@Column(name="fleet_column_in_your_table_name", nullable=false) 
public Fleet getFleet() {   
    return fleet;  
} 

のようなテーブルと列のマッピングを追加する必要があります
