    @Test
    void contextLoads() {
        var tab="hot";
        var page = PageRequest.of(pageNo, pageSize);
        var t = QBmsPost.bmsPost;
        var u = QUmsUser.umsUser;
        var now = new Date();
        var tomorrow = DateUtils.addDays(now, 1);
        var query = queryFactory
                .selectFrom(t)
                .leftJoin(u)
                .on(t.userId.eq(u.id));
        if (tab.equals("hot")) query = query.where(t.createTime.lt(tomorrow));
        var re = (!tab.equals("hot")) ?
                query.orderBy(t.createTime.desc()) :
                query.orderBy(t.view.desc(), t.createTime.desc());
        var er =re.fetch();
    }

}

Answer

You have mixed versions of querydsl. I guess you are having querydsl-core version 4.4.x while your querydsl-jpa is of version 5.0.0.M1. (this is probably caused by a spring-boot starter library.)

Anyhow, this can easily fixed by explicitely adding the correct version of querydsl-core as dependency.

<dependency>
    <groupId>com.querydsl</groupId>
    <artifactId>querydsl-core</artifactId>
    <version>5.0.0.M1</version>
</dependency>
