Question

我正在使用Hibernate和Spring Data，我正在尝试使用SpEL以下列方式创建自定义合并查询：

  <script type="text/javascript">
     speechSynthesis.speak(new SpeechSynthesisUtterance(myString));
  </script>

结果如下

@Modifying
@Query("UPDATE Order o SET o.serial = COALESCE(?#{#another.serial}, o.serial), " +
        "o.owner = COALESCE(?#{#another.owner}, o.owner)")
Order nullSafeUpdate(@Param("another") Order another);

我已尝试根据这些guidelines将替换为：并删除＃。

订单实体包含所有变量的公共getter和setter。

使用Spring数据 1.6.6

更新

似乎 JpaQueryMethod 验证器 assertParameterNamesInAnnotatedQuery 甚至不检查SpEL表单中包含的参数

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'orderRepository': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalStateException: Using named parameters for method public abstract test.test.test.test.Order test.test.test.test.OrderRepository.nullSafeUpdate(test.test.test.test.Order) but parameter 'another' not found in annotated query 'UPDATE Order o SET o.serial = COALESCE(?#{#another.serial}, o.serial), o.owner = COALESCE(?#{#another.owner}, o.owner)'!

使用SpEL自定义合并JPA查询
