SpringBoot Rest 最佳实践的一些疑问

不得已要做后端开发，于是按照官方指导使用 SrpingBoot Web + JPA + Rest

• implementation 'org.springframework.boot:spring-boot-starter-web'
• implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
• implementation 'org.springframework.boot:spring-boot-starter-data-rest'

写起来比较愉快,

domain 如下：

@Entity
@Getter
@Setter
public class Account {

    @Id
    @Column(nullable = false, updatable = false)
    @SequenceGenerator(
            name = "account_sequence",
            sequenceName = "account_sequence",
            allocationSize = 1,
            initialValue = 10000
    )
    @GeneratedValue(
            strategy = GenerationType.SEQUENCE,
            generator = "account_sequence"
    )
    private Long id;

    @Column(nullable = false, unique = true, updatable = false)
    private String account;

    @Column(nullable = false)
    private String passwd;

    @Column
    private String salt;

    @Column
    private String nonce;

    @OneToOne
    @JoinColumn(nullable = false, updatable = false, unique = true)
    private Member member;
    
    // 偷个懒,投影直接下载这个类内部了
    @Projection(name = "accountDTO", types = Account.class)
    public interface AccountDTO {
        String getAccount();
        String getSalt();
    }
}

仓储接口

@RepositoryRestResource(excerptProjection = Account.AccountDTO.class)
public interface AccountRepository extends JpaRepository<Account, Long> {}

此时启动工程，http://127.0.0.1/accounts接口中 account 的属性 passwd 由于投影的缘故没显示 大约是这个样子,这符合我的预期，我很欣慰！

{
    "_embedded": {
        "accounts": [
            {
                "account": "1008610010",
                "salt": "xxxxx",
                // 这里的 passwd 和 nonce 都没有了
                "_links": {
                    "self": {
                        "href": "http://127.0.0.1/accounts/10000"
                    },
                    "account": {
                        "href": "http://127.0.0.1/accounts/10000{?projection}",
                        "templated": true
                    },
                    "member": {
                        "href": "http://127.0.0.1/accounts/10000/member"
                    }
                }
            }
        ]
    },
    "_links": {
        "self": {
            "href": "http://127.0.0.1/accounts"
        },
        "profile": {
            "href": "http://127.0.0.1/profile/accounts"
        }
    },
    "page": {
        "size": 20,
        "totalElements": 1,
        "totalPages": 1,
        "number": 0
    }
}

此时调用http://127.0.0.1/accounts/10000，结果不该出现的 passwd 和 nonce 冒出了头。我很想跳起来对着他的狗头就是一脚。

{
    "account": "1008610010",
    "passwd": "999999",// <===========================这里
    "salt": "salt",   
    "nonce": "nonce",// <===========================这里
    "createAt": "2021-06-22T15:01:17.50913+08:00",
    "modifyAt": "2021-06-22T15:01:24.41396+08:00",
    "_links": {
        "self": {
            "href": "http://127.0.0.1/accounts/10000"
        },
        "account": {
            "href": "http://127.0.0.1/accounts/10000{?projection}",
            "templated": true
        },
        "member": {
            "href": "http://127.0.0.1/accounts/10000/member"
        }
    }
}

在此，征求广大外出务工人员，授我渔，喂我🐟！提供一些 SrpingBoot JPA REST 一些常用的套路，值得细读和探讨的资料。

叩首！！！
