我一直收到此错误，但无法找到解决方法。无法确定类型：org.digitalcorpse.pirates.Pirate，对于列：[org.hibernate.mapping.Column（pirate）]

package org.digitalcorpse.pirates;

        this.skillFixing = skillFixing;
    }

    public int getSkillLeadership() {

    }

    public void setSkillLeadership(int skillLeadership) {
        this.skillLeadership = skillLeadership;
    }

    public int getSkillMaps() {

    }

    public void setSkillMaps(int skillMaps) {
        this.skillMaps = skillMaps;

您应该像这样为表和列添加映射 @Table（name =“my_pirate_table”）

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