使用Hibernate、JPQL和Postgres函数时出现意外标记：&#39；&lt；Function_Name&gt；&#39；错误

unexpected token: #39;lt;function_namegt;#39; error when using hibernate, JPQL and postgres function(使用Hibernate、JPQL和Postgres函数时出现意外标记：#39；lt；Function_Namegt；#39；错误)

问题描述

我将PostgreSQL 9.6与Hibernate 5.4.8、Java 8和Spring框架一起使用。我需要调用postgres函数

CREATE OR REPLACE FUNCTION function_that_return_array(givenIds character varying(255)) RETURNS int[] AS
'
BEGIN
    RETURN string_to_array($1,'','');
END
' LANGUAGE plpgsql;

在JPQL查询中

private static final String JPQL_QUERY =
    " SELECT NEW com.package.CustomProjection( " +
    "  e.id, " +
    "  e.value " +
    " ) " +
    " FROM SomeEntity e " +
    " WHERE e.id = ANY(function_that_return_array(:ids))";

和使用实体管理器：

@Autowired
private final EntityManager entityManager;

// ...

this.entityManager.createQuery(JPQL_QUERY, CustomProjection.class)
                .setParameter("ids", "1,2,3")
                .getResultList();

并导致以下异常：

antlr.NoViableAltException: unexpected token: function_that_return_array
    at org.hibernate.hql.internal.antlr.HqlBaseParser.selectFrom(HqlBaseParser.java:1055) [hibernate-core-5.4.8.Final.jar:5.4.8.Final]

    at org.hibernate.hql.internal.antlr.HqlBaseParser.statement(HqlBaseParser.java:215) [hibernate-core-5.4.8.Final.jar:5.4.8.Final]

上面的例子非常简单，但它正确地表示了生产问题。当我在原生SQL中调用上面的函数时，它工作得很好：

select *
from some_entity e 
where e.id = ANY(function_that_return_array('1,2,3,4'))

有谁知道如何在JPQL和Hibernate中调用postgres函数，或者能指出我做错了什么？我读了很多文章like this one，所以我试了几十个组合，但到目前为止都没有成功。提前谢谢。

unexpected token: function_that_return_array

function('function_that_return_array', '1,2,3,4')

function_that_return_array('1,2,3,4')

public class MyDialect extends PostgreSQLXXDialect {
    public MyDialect() {
        super();
        registerFunction("function_that_return_array", new StandardSQLFunction("function_that_return_array"));
    }
}
