java - Hibernate/Spring Data JPA无法在Spring Boot应用程序中识别WITHIN关键字

我在实体/ Pojo类中的属性之一中使用了@Formula批注。在运行时，它正在创建一个查询以获取结果，并且由于无法将ORA-02000: missing WITHIN keyword识别为关键字而引发了ERROR WITHIN。

Marks.java

@Formula("(SELECT CASE WHEN dis_order IS NULL THEN (SELECT listagg(qpm.displayed_order,', ') WITHIN GROUP (ORDER BY qpm.displayed_order) FROM que_post_mark qpm WHERE qpm.es_id = es_id AND qpm.sez_id = sez_id GROUP BY qpm.es_id, qpm.sez_id) ELSE NULL END FROM dual)")
private String childItemsDisplayedOrder;

生成的查询如下所示:

select marks0_.*,
(SELECT
    CASE
        WHEN marks0_.displayed_order IS NULL THEN (SELECT
            listagg(qpm.displayed_order,
            ', ') marks0_.WITHIN
        GROUP (ORDER BY
            qpm.displayed_order)
        FROM
            que_post_mark qpm
        WHERE
            qpm.es_id  = marks0_.es_id
            AND qpm.sez_id = marks0_.sez_id
        GROUP BY
            qpm.es_id ,
            qpm.sez_id)
        ELSE NULL
    END
FROM
    dual) as formula2_0_
from
    MARKS marks0_
where
    marks0_.es_id =?

它正在将WITHIN标识为列，并附加别名名称，例如marks0_.WITHIN
我正在使用以下版本:

 spring-boot-starter-web = 1.4.0.RELEASE, spring-data-jpa:jar:1.10.2 ,hibernate-entitymanager:jar:5.1.3' hibernate-core:jar:5.1.3, hibernate-jpa-2.1-api:jar

我试图降低这些jar版本以使其正常运行，但没有成功。

错误Stacktrace如下所示:

谁能帮我解决这个问题？

最佳答案

我已经通过扩展this link中提到的休眠方言类解决了此问题。

public class Oracle10gDialectExtended extends Oracle10gDialect {
    public Oracle10gDialectExtended() {
        super();
        registerKeyword("within"); //Keyword has to be in lowercase.
    }
}

为此新类设置“hibernate.dialect”属性。

Properties.setProperty("hibernate.dialect", "com.example.Oracle10gDialectExtended");
