有没有特别好的方法可以做到这一点？我使用 Panache/Hibernate ORM 来扩展 PanacheEntity 以为新表的架构创建映射。一切都使用 Repository 方法按预期工作，我有正确的端点来反映 GET、PUT 等。我目前的问题是我试图有一个完全不同的端点，它只在 Postgresql 函数/存储过程上执行 GET 并返回当你到达那个端点时的那个数据。这是终点——

import javax.inject.Inject;
import javax.persistence.EntityManager;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;



@Path("/holidays")
@Produces("application/json")
@Consumes("application/json")
public class HolidayResource {

    @Inject
    EntityManager entityManager;

    @GET
    public Holiday[] get() {
        return entityManager.createNamedQuery("Holidays.findAll", Holiday.class)
                .getResultList().toArray(new Holiday[0]);
    }
    
}

这是对象/类 -

import java.sql.Date;
import java.sql.Timestamp;

import javax.persistence.Entity;
import javax.persistence.Id;

import org.hibernate.annotations.NamedNativeQuery;


@Entity
@NamedNativeQuery(name = "Holidays.findAll", query = "SELECT * FROM holidays.usa('NY', 2020, 2020)")
public class Holiday {


    public static enum Authority {
        federal,
        national,
        bank,
        provincial,
        state,
        informal,
        observance,
        shortened_work_day,
        optional,
        de_facto,
        religious,
        extra_work_day,
        municipal
    }

    @Id public long id;
    public Date datestamp;
    public String description;
    public Authority authority;
    public Boolean day_off;
    public Boolean observation_shifted;
    public Timestamp start_time;
    public Timestamp end_time;

}

请注意，我并不是想创建一个表格或任何只是为了显示的东西。这是堆栈跟踪，但我尝试了一些似乎让我陷入困境的事情（例如添加 getter/setter 和其他东西） -

Postgres 函数/存储过程是根据我在某处找到的 Python 脚本创建的，它会像这样被调用，并反映在@NamedNativeQuery注释中。-

SELECT * from holidays.usa('NY', 2020, 2020);

查询返回的示例 -

datestamp       description                authority      day_off      observation_shifted   start_time   end_time        
[DATE]          [TEXT]                     [ENUM]         [BOOLEAN]    [BOOLEAN]             [TIME]       [TIME]
------------    -----------------------    -----------    ---------    -------------------   ----------   ----------
"2020-01-01"    "New Year's Day"           "federal"       true        false                 "00:00:00"   "24:00:00"
"2020-02-17"    "Family Day"               "provincial"    true        false                 "00:00:00"   "24:00:00

有一个更好的方法吗？我尝试过的一些事情似乎把我带入了错误的圈子。

对于SRCFG00013: No Converter registered for interface java.nio.file.Path像我一样登陆这里的未来读者：

我遇到了类似的问题并得到了相同的 SRCFG00013 错误消息，但听起来很愚蠢，解决方案是在日志文件中向上滚动，因为带有有意义消息的真正休眠堆栈跟踪远远高于这个神秘的 SRCFG00013 错误.

您可以定义一个@NamedStoredProcedure：

@NamedStoredProcedureQuery(
    name = "Holidays.findAll", 
    procedureName = "holidays.usa", 
    resultClasses = Holiday.class, 
    parameters = {
            @StoredProcedureParameter(
                name = "city",
                type = String.class,
                mode = ParameterMode.IN
            ),
            @StoredProcedureParameter(
                name = "year",
                type = Integer.class,
                mode = ParameterMode.IN
            ),
            // Additional parameters
            ...
        }
)

@Entity
public class Holiday {
}

List<Holiday> holidays = entityManager
.createNamedStoredProcedureQuery( "Holidays.findAll" )
.setParameter( "city", "NY" )
.setParameter( "year", 2020 )
 ...
.getResultList();

或者您可以通过 entityManager 调用存储过程：

StoredProcedureQuery query = entityManager.createStoredProcedureQuery( "holidays.usa", Holiday.class);
query.registerStoredProcedureParameter( "city", String.class, ParameterMode.IN);
query.registerStoredProcedureParameter( "year", Integer.class, ParameterMode.IN);
... // register other parameters

query.setParameter("city", "NY");
query.setParameter("year", 2020);
... // set other parameters
List<Holiday> holidays = query.getResultList();
