Spring Jpa Hibernate 列未轉換為查詢

Question

JPA 不翻譯 sql 語句中的 @Column(name="...") 錯誤日志

[6418c947-1] There was an unexpected error (type=Internal Server Error, status=500).
PreparedStatementCallback; bad SQL grammar [SELECT mwo_main_status._id AS _id, mwo_main_status.oid AS oid, mwo_main_status.label AS label, mwo_main_status.details AS details FROM mwo_main_status]; nested exception is org.postgresql.util.PSQLException: ERROR: column mwo_main_status.oid does not exist Dica: Perhaps you meant to reference the column "mwo_main_status._id". Posição: 36

我的 ORM

@Builder
@Data
@Entity
@Table("mwo_sub_status")
public class WorkOrderSubStatusDbMapping {

    @GeneratedValue(strategy= GenerationType.IDENTITY)
    private @Id Integer _id;

    @Column(name="ref_id")
    private Integer oid;
    private String label;
    private String details;
}

我預計生成的 SQL 是：

SELECT mwo_main_status._id AS _id, mwo_main_status.ref_id AS oid, mwo_main_status.label AS label, mwo_main_status.details AS details FROM mwo_main_status

我正在創建一個帶有子模塊（Web、域、持久性）的 Spring-Boot 應用程序
在持久性模塊中，我的 gradle.build 文件是

apply plugin: 'java-library'

dependencies {
    implementation project(':domain')
    implementation 'io.projectreactor:reactor-core:3.3.3.RELEASE'
    implementation 'org.springframework:spring-context:5.2.4.RELEASE'

    implementation 'org.springframework:spring-orm:5.2.4.RELEASE'
    implementation 'org.springframework.data:spring-data-jdbc:1.1.5.RELEASE'

    implementation 'org.hibernate:hibernate-core:5.4.11.Final'
    runtimeOnly('org.postgresql:postgresql')

    runtimeOnly('org.postgresql:postgresql')

    testImplementation 'junit:junit:4.12'
}

我錯過了什么？

正如在實體上使用 lomboks @Data 和 @Builder 中所說，Lombok 不適用於 jdbc，所以我決定使用spring-data-jpa而不是spring-data-jdbc 。

謝謝亞歷克斯魯登科。

可能，可能是這樣

@Entity
@Table(name = "mwo_main_status")
public class WorkOrderSubStatusDbMapping {
    @Id
    @GeneratedValue(strategy= GenerationType.IDENTITY)
    private Integer _id;

    @Column(name = "ref_id")
    private Integer oid;
    private String label;
    private String details;    
}
