本文介绍了一个基于Java的反馈系统设计，使用Hibernate注解实现数据库表结构，包括自增主键、多个索引及字段注释，展示了实体类FeedBack的详细属性设置。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

@Table(schema = "feedback",indexes = {@Index(name = "opinion_key",columnList = "opinion",unique = true),@Index(name =
        "title_key",columnList = "title")})

可添加多个索引，形式如上所示

@org.hibernate.annotations.Table(appliesTo = "feedback",comment="反馈")

表名注释

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)

主键注解，形式为自增

@Column(name = "opinion", columnDefinition = "varchar(500) COMMENT '反馈意见'")

规定了某一列的字段名和大小

@Table(schema = "feedback",indexes = {@Index(name = "opinion_key",columnList = "opinion",unique = true),@Index(name =
        "title_key",columnList = "title")})
@org.hibernate.annotations.Table(appliesTo = "feedback",comment="反馈")
@Entity
@Builder
@NoArgsConstructor
@AllArgsConstructor
@Setter
@Getter
@Proxy(lazy = false)
public class FeedBack extends BaseEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(name = "title")
    private String title;

    @Column(name = "opinion", columnDefinition = "varchar(500) COMMENT '反馈意见'")
    private String opinion;

    @Column(name = "contact_information")
    private String contactInformation;

    @Column(name = "document_id")
    private String documentId;

    @Column(name = "is_completed")
    private Boolean isCompleted;
}
