querydsl: java.lang.NoSuchFieldError: TREATED_PATH

Question

springboot版本是2.51，java vsersion 1.8它会在selectFrom()中崩溃，错误信息：java.lang.NoSuchFieldError：TREATED_PATH

怎么解决啊，网上找不到方法

这是我的代码

@SpringBootTest
class Demo4ApplicationTests {
    @Resource
    private BmsPostRepository bm;
    @Autowired
    private JPAQueryFactory queryFactory;
    @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();
    }

}

有依赖性

            <scope>compile</scope>
            <groupId>com.querydsl</groupId>

您有 querydsl 的混合版本。我猜您使用的是 querydsl-core 版本 4.4.x，而您的 querydsl-jpa 版本为 5.0.0.M1。（这可能是由 spring-boot 启动库引起的。）

无论如何，通过显式添加正确版本的 querydsl-core 作为依赖项，可以轻松解决此问题。

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