java - QueryDSL意外 token ，带有any()和in子句

我有两个模型，Location和LocationAttribute，具有多对多关系。
我有一个LocationAttribute ID列表，并希望找到至少有一个的所有Locations
这些属性。

Location.java:

@Entity
public class Location {

    @Id
    @GeneratedValue
    @Column(name="LOCATION_ID")
    protected int id;

    @ManyToMany(targetEntity = LocationAttribute.class)
    @JoinTable(name="LOCATION_TO_LOCATION_ATTRIBUTE",
            joinColumns = @JoinColumn(name="LOCATION_ID", referencedColumnName = "LOCATION_ID"),
            inverseJoinColumns = @JoinColumn(name="LOCATION_ATTRIBUTE_ID", referencedColumnName = "LOCATION_ATTRIBUTE_ID")
    )
    private List<LocationAttribute> locationAttributes;
}

LocationAttribute.java:

@Entity
public class LocationAttribute {

    @Id
    @GeneratedValue
    @Column(name="LOCATION_ATTRIBUTE_ID")
    protected int id;
}

我尝试了以下QueryDSL代码:

List<Integer> locationAttributeIds = new ArrayList<Integer>();
locationAttributeIds.add(1);
locationAttributeIds.add(2);
locationAttributeIds.add(3);

QLocation location = QLocation.location;
JPAQuery query = new JPAQuery(entityManager, JPQLTemplates.DEFAULT);
query.from(location) .where(location.locationAttributes.any().id.in(locationAttributeIds));
query.list(location);

如果locationAttributeIds具有0或1个元素，则代码工作正常。但是，当我有多个元素时，会出现此错误:

java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: , near line 5, column 53 [select location
from ch.locatee.test.querydslerror.locatee.Location location
where exists (select location_locationAttributes_cc6d8
from location.locationAttributes as location_locationAttributes_cc6d8
where location_locationAttributes_cc6d8.id in :x1_0_, :x1_1_, :x1_2_)]

    at ch.locatee.test.querydslerror.locatee.AppTest.testSomething(AppTest.java:63)

我找到了很多与该问题相关的站点，但不确定如何解决该问题。

我做了一个快速测试项目，您可以在Github上找到它:https://github.com/bekoeppel/QueryDslInErrorTest。 mvn test产生以上错误。

我希望您能从列表中找到至少具有Locations之一的所有LocationAttribute.id的想法。谢谢!

最佳答案

请改用以下JPAQuery构造函数

new JPAQuery(entityManager);

JPQLTemplates提供通用序列化，无法找到Hibernate的所有JPQL变体。仅使用EntityManager参数，Querydsl将为您选择正确的JPQLTemplates子类实例。
