回购类
public interface PersonRepository extends CrudRepository<Person, Long>{
@Query("{'name' : ?0}")
public Iterable<Person> searchByName(String personName);
@Query(value = "{'addresses.$city' : ?0'}")
Person findByAddresses_City(String city);
}
结果
/* 1 */
{
"_id" : NumberLong(1),
"name" : "Achilles",
"age" : 0,
"addresses" : [],
"_class" : "com.example.demo.model.Person"
}
/* 2 */
{
"_id" : NumberLong(2),
"name" : "Hektor",
"age" : 0,
"addresses" : [
{
"$ref" : "address",
"$id" : NumberLong(1),
"$db" : "address"
}
],
"_class" : "com.example.demo.model.Person"
}
在两个查询下面都中断了！
Below both the queries breaks !
Person p = personRepository.findByAddresses_City("221b Baker Street");
System.out.println(p);
和
Query query = new Query(Criteria.where("addresses.$id").is(new ObjectId("2")));
List<Person> l = mongoTemplate.find(query, Person.class);
System.out.println(l);
编辑-1:我更正了:Query query = new Query(Criteria.where("addresses.$id").is(1L));
但这仍然没有带来任何东西.
But this still doesn't brings anything.
推荐答案
去掉?0附近的单引号，在你写的代码中?0':
Remove the single quote near ?0, in your code you have written ?0':
@Query(value = "{'addresses.$city' : ?0'}")
应该
@Query(value = "{'addresses.$city' : ?0}")
