我不太喜欢Spring Data JPA(使用Hibernate 4.3.11.Final)，我有以下情况。
我有这个 SQL 查询(直接在 MySql 中执行效果很好)，该查询只是查找注册到 accomodation 表中、从选定点到特定范围内的所有酒店:
SET @fiumicino = GeomFromText('POINT(41.768835 12.247658)');
SELECT *
FROM accomodation a
WHERE earth_circle_distance(@fiumicino, a.geographical_position) < 7
正如您在前面的代码中看到的，该查询有 2 个参数:
- @fiumicino:这是一个 MySqk Spatial POINT 对象。
- 7:这只是一个范围。
好的，工作正常...
因此，我尝试将其转换为 native SQL 查询到我的 Spring Data JPA 存储库接口(interface)中，我已经完成了:
@Repository
public interface AccomodationDAO extends JpaRepository<Accomodation, Long> {
@Query(value = "SELECT * FROM accomodation a WHERE earth_circle_distance(?0, a.geographical_position) < ?1", nativeQuery = true)
Accomodation findByRange(Point location, int range);
}
基本上，我已将 @fiumicino 替换为 ?0 参数，并将距离范围的 7 值替换为 ?1 。
然后我创建了这个简单的单元测试方法:
@Test
public void findByRangeTest() throws ParseException {
System.out.println("findByRangeTest() START");
Accomodation accomodation = null;
int range = 7;
double lat = 41.768835;
double lon = 12.247658;
Point location = GisUtils.buildGeometry(lat, lon);
accomodation = accomodationDAO.findByRange(location, range);
assert(accomodation != null);
System.out.println("findByRangeTest() END");
}
问题是，当此方法执行 findByRange() 方法时，我在堆栈跟踪中收到以下异常:

那么，这个异常(exception)究竟意味着什么？如果在我的查询中我只有 2 个参数 ?0 和 ?1 ，为什么它引用位置为 [2] 的参数？
出了什么问题？我缺少什么？我该如何解决这个问题？
最佳答案
在绑定(bind)语句中索引从 1 开始。
这应该有效:
@Repository
public interface AccomodationDAO extends JpaRepository<Accomodation, Long> {
@Query(value = "SELECT * FROM accomodation a WHERE earth_circle_distance(?1, a.geographical_position) < ?2", nativeQuery = true)
Accomodation findByRange(Point location, int range);
}

关于java - 为什么我在 Spring Data JPA native SQL 查询中获取此异常？非法参数异常 : Parameter with that position [2] did not exist，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40495392/
