使用nativeQuery的Spring Boot Query注释在Postgresql中不起作用

spring-boot

开发环境。

OS: windows 8
IDE : Eclipse Luna with JAVA 8
Postgresql : 9.3.4 in OPENBSD 5.5

其他的所有JPA查询（例如findFirst3ByTextOrderByTextAsc）都可以正常工作。但不是在NativeQuery中，尤其是在INTERVAL中

资料库

@RepositoryRestResource(collectionResourceRel = "Nodes", path = "Nodes")
public interface NodeRepository extends 
JpaRepository<Node, Integer>, 
CrudRepository<Node, Integer>,
PagingAndSortingRepository<Node, Integer>,
Repository<Node, Integer>
{
    //1st INTERVAL is native keyword in POSTGRESQL
    @Query(value = "SELECT n.* from nodes n WHERE n.node_id = 10510 AND n.last_good_ping > CURRENT_DATE - INTERVAL '1 day' ", nativeQuery = true)
    List<Node> getLast24HoursByNodeId();

    //2nd
    @Query(value = "SELECT n.* from nodes n WHERE n.node_id = 10510 AND n.last_good_ping > CURRENT_DATE - INTERVAL :interval ", nativeQuery = true)
    List<Node> getByNodeIdAndInterval(@Param("interval") String interval);

    //3rd
    @Query(value = "SELECT n.* from nodes n WHERE n.node_id = 10510 AND n.last_good_ping > CURRENT_DATE - INTERVAL  ?1", nativeQuery = true)
    List<Node> getByNodeIdAndInterval(String interval);     
}

第一个查询可以在测试中找到，但在第二个，第三个查询中却找不到

测试

...
//1st
@Test
public void getLast24HoursByNodeId(){
    List<Node> nodes = repo.getLast24HoursByNodeId();
    log.debug(nodes.size());
    Assert.assertTrue(nodes.size() > 0);                
}

//2st
@Test
public void getByInterval(){
    List<Node> nodes = repo.getByNodeIdAndInterval("1 day".toString());

    log.debug(nodes.size());
    Assert.assertTrue(nodes.size() > 0);                
}   
...

我认为在[生成查询]或[获取并分配给域对象]过程中出现了问题。

请帮忙〜

好的，我花了很长时间尝试为我完成这项工作，但是我终于明白了。让未来的冒险家和社区也知道这一点。

对我有用的是强制转换到AH提出的间隔：

select current_timestamp + ( 2 || ' days')::interval;

您的解决方案将是这样的（分析第二个查询时）：

@Query(value = "SELECT n.* from nodes n WHERE n.node_id = 10510 AND n.last_good_ping > CURRENT_DATE - ( :interval )\\:\\:interval ", nativeQuery = true)

或对于第三次查询（这正是我根据自己的情况进行工作的方式）

@Query(value = "SELECT n.* from nodes n WHERE n.node_id = 10510 AND n.last_good_ping > CURRENT_DATE - ( ?1 )\\:\\:interval", nativeQuery = true)

请注意转义::变成\\:\\:。在您要在SQL编辑器中测试的纯SQL中::，但是@Query需要转义这些强制转换符号内的存储库代码（否则，您的Hibernate
/ JPA将不满意）。
