Question

У меня есть один объект, который является объектом продукта:

package com.amitbaz.tradingsystem; 

import javax.persistence.Column; 
import javax.persistence.GeneratedValue; 
import javax.persistence.GenerationType; 
import javax.persistence.Id; 

import org.hibernate.annotations.DynamicUpdate; 
import org.hibernate.annotations.NamedQueries; 
import org.hibernate.annotations.NamedQuery; 
import org.hibernate.annotations.Table; 

@DynamicUpdate(true) 
@Table(appliesTo = "productTable") 
@NamedQueries({ 
    @NamedQuery(name = "com.amitbaz.tradingsystem.product.GetAll", query= "select p from Product p"), 
    @NamedQuery(name = "com.amitbaz.tradingsystem.product.GetByName", query= "select p from Product p where p.fullName like :name") 

}) 
public class Product { 

    @Id 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    @Column(name = "product_id") 
    private int id; 

    @Column(name="product_name") 
    private String fullName; 

    @Column(name="product_info") 
    private String info; 

    @Column(name="product_price") 
    private float price; 

    @Column(name="product_base_currency") 
    private String baseCurrency; 

    public Product(String fullName, String info, float price, String baseCurrency) { 
     this.fullName = fullName; 
     this.info = info; 
     this.price = price; 
     this.baseCurrency = baseCurrency; 
    } 
} 

и DAO выглядит следующим образом:

package com.amitbaz.tradingsystem; 

import org.hibernate.Hibernate; 
import org.hibernate.Session; 
import org.hibernate.SessionFactory; 
import java.util.List; 

import io.dropwizard.hibernate.AbstractDAO; 

public class ProductDAO extends AbstractDAO<Product>{ 


    public ProductDAO(SessionFactory sessionFactory) { 
     super(sessionFactory); 
     // TODO Auto-generated constructor stub 
    } 

    public List<Product> getAll(){ 
     return list(namedQuery("com.amitbaz.tradingsystem.product.GetAll")); 
    } 

    public List<Product> getByName(String name){ 
     StringBuilder builder = new StringBuilder("%"); 
     builder.append(name).append("%"); 
     return list(namedQuery("com.amitbaz.tradinsystem.product.GetByName").setParameter("name", builder.toString())); 
    } 

} 

Я также инициализируется hibernateBundle в классе приложения и зарегистрировал ресурс в окружающую среду:

package com.amitbaz.tradingsystem; 


import org.glassfish.jersey.server.filter.RolesAllowedDynamicFeature; 
import org.hibernate.Hibernate; 
import org.skife.jdbi.v2.DBI; 

import io.dropwizard.Application; 
import io.dropwizard.auth.AuthDynamicFeature; 
import io.dropwizard.auth.AuthValueFactoryProvider; 
import io.dropwizard.auth.CachingAuthenticator; 
import io.dropwizard.auth.basic.BasicCredentialAuthFilter; 
import io.dropwizard.auth.basic.BasicCredentials; 
import io.dropwizard.db.DataSourceFactory; 
import io.dropwizard.db.PooledDataSourceFactory; 
import io.dropwizard.hibernate.HibernateBundle; 
import io.dropwizard.jdbi.DBIFactory; 
import io.dropwizard.setup.Bootstrap; 
import io.dropwizard.setup.Environment; 

public class TradingSystemApplication extends Application<TradingSystemConfiguration>{ 

    public static void main(String[] args) throws Exception{ 
     new TradingSystemApplication().run(args); 
    } 

    private final HibernateBundle<TradingSystemConfiguration> HibernateBundle = new HibernateBundle<TradingSystemConfiguration>(Product.class){ 

     @Override 
     public DataSourceFactory getDataSourceFactory(TradingSystemConfiguration config) { 
      // TODO Auto-generated method stub 
      return config.getDataSourceFactory(); 
     } 


    }; 



    @Override 
    public void initialize(Bootstrap<TradingSystemConfiguration> bootstrap) { 
     // TODO Auto-generated method stub 
     bootstrap.addBundle(HibernateBundle); 
    } 



    @Override 
    public void run(TradingSystemConfiguration config, Environment env) throws Exception { 
     // TODO Auto-generated method stub 

     //final DBIFactory factory = new DBIFactory(); 
     //final DBI jdbi = factory.build(env, config.getDataSourceFactory(), "mysql"); 
     //final TestResource testRes = new TestResource(); 
     //final UserDAO dao = jdbi.onDemand(UserDAO.class); 
     final ProductDAO productDAO = new ProductDAO(HibernateBundle.getSessionFactory()); 
     env.jersey().register(new ProductResource(productDAO)); 
     env.jersey().register(new TestResource()); 
     env.jersey().register(new AuthDynamicFeature(
       new BasicCredentialAuthFilter.Builder<User>() 
       .setAuthenticator(new TradingSystemAuthenticator()) 
       .setAuthorizer(new TradingSystemAuthorizer()) 
       .setRealm("SHITTT") 
       .buildAuthFilter())); 

     env.jersey().register(RolesAllowedDynamicFeature.class); 
     env.jersey().register(new AuthValueFactoryProvider.Binder<>(User.class)); 

    } 

} 

Теперь, когда я тестирую эти запросы, я получаю ошибка 500 и ошибка Named query not known: <name of the query> в журналах сервера

попытайтесь добавить javax.persistence @Entity аннотацию к вашему классу продуктов.
