Question

我在CrudRepository中有以下API

public static final String getVendorOrder ="select new com.meha.ps.order.dto.VendorOrder(orderItem.vendorItemId"
        + ",order.orderId"
        + ",order.createTime"
        + ",order.modTime "
        + ",org.orgId"
        + ",org.orgType"
        + ") from Order order inner join order.OrderItem orderItem on order.orderId=orderItem.orderId"
        + " inner join Org org on org.orgId=orderItem.vendorId"
        + " where orderItem.vendorItemId in :vendorItemIds";

@Query(getVendorOrder)
List<VendorOrder> findVendorOrder(@Param("vendorItemIds") List<Integer> vendorItemIds);

在启动时遇到以下错误：

Caused by: java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: order near line 1, column 193 [select new com.meha.ps.order.dto.VendorOrder(orderItem.vendorItemId,order.orderId,order.createTime,order.modTime ,org.orgId,org.orgType) from com.meha.ps.order.entities.Order order inner join order.OrderItem orderItem on order.orderId=orderItem.orderId inner join Org org on org.orgId=orderItem.vendorId where orderItem.vendorItemId in :vendorItemIds]

引起：org.hibernate.hql.internal.ast.QuerySyntaxException：意外令牌：第1行附近的订单，第193列[select new com.meha.ps.order.dto.VendorOrder（orderItem.vendorItemId，order.orderId），order.createTime，order.modTime，org.orgId，org.orgType）来自com.meha.ps.order.entities.Order命令内连接order.OrderItem orderItem on order.orderId = orderItem.orderId inner join org org on org .orgId = orderItem.vendorId其中orderItem.vendorItemId in：vendorItemIds] 在org.hibernate.hql.internal.ast.QuerySyntaxException.convert（QuerySyntaxException.java:74）〜[hibernate-core-5.0.11.Final.jar：5.0.11.Final] 在org.hibernate.hql.internal.ast.ErrorCounter.throwQueryException（ErrorCounter.java:91）〜[hibernate-core-5.0.11.Final.jar：5.0.11.Final] 在org.hibernate.hql.internal.ast.QueryTranslatorImpl.parse（QueryTranslatorImpl.java:288）〜[hibernate-core-5.0.11.Final.jar：5.0.11.Final] 在org.hibernate.hql.internal.ast.QueryTranslatorImpl.doCompile（QueryTranslatorImpl.java:187）〜[hibernate-core-5.0.11.Final.jar：5.0.11.Final] 在org.hibernate.hql.internal.ast.QueryTranslatorImpl.compile（QueryTranslatorImpl.java:142）〜[hibernate-core-5.0.11.Final.jar：5.0.11.Final] 在org.hibernate.engine.query.spi.HQLQueryPlan。（HQLQueryPlan.java:115）〜[hibernate-core-5.0.11.Final.jar：5.0.11.Final] 在org.hibernate.engine.query.spi.HQLQueryPlan。（HQLQueryPlan.java:76）〜[hibernate-core-5.0.11.Final.jar：5.0.11.Final] 在org.hibernate.engine.query.spi.QueryPlanCache.getHQLQueryPlan（QueryPlanCache.java:150)~ [hibernate-core-5.0.11.Final.jar：5.0.11.Final] 在org.hibernate.internal.AbstractSessionImpl.getHQLQueryPlan（AbstractSessionImpl.java:302）〜[hibernate-core-5.0.11.Final.jar：5.0.11.Final] 在org.hibernate.internal.AbstractSessionImpl.createQuery（AbstractSessionImpl.java:240）〜[hibernate-core-5.0.11.Final.jar：5.0.11.Final] 在org.hibernate.internal.SessionImpl.createQuery（SessionImpl.java:1894）〜[hibernate-core-5.0.11.Final.jar：5.0.11.Final] 在org.hibernate.jpa.spi.AbstractEntityManagerImpl.createQuery（AbstractEntityManagerImpl.java:291）〜[hibernate-entitymanager-5.0.11.Final.jar：5.0.11.Final] ...省略了102个常见帧

如果某些实体之间没有直接映射，那么我建议一直使用旧样式连接（查询的其余部分似乎没问题）：

<persistence-unit name="defaultPersistenceUnit" transaction-type="RESOURCE_LOCAL">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    <non-jta-data-source>MMChat</non-jta-data-source>
    <properties>
        <property name="hibernate.archive.autodetection" value="class" />
        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" />
        <property name="hibernate.hbm2ddl.auto" value="create-drop" />
    </properties>
</persistence-unit>

spring boot JPA IN子句不起作用
