Dropwizard：「錯誤處理您的請求」從數據庫

retriving數據。當我試圖打開Dropwizard：「錯誤處理您的請求」從數據庫

http://localhost:8080/tailor/orders

應該返回database.but所有的命令它產生錯誤

{"message":"There was an error processing your request. It has been logged (ID fe49a13e76c59894)."}

我我無法追查這是什麼原因導致的問題。

我正在使用dropwizard進行寧靜的Web服務和從dropwizard進行休眠以執行sqlight數據庫。

類：

資源類：

@Path("/tailor") 
@Produces(MediaType.APPLICATION_JSON) 
public class TailorResource { 

OrderDAO orderdao; 

public TailorResource(OrderDAO odao) { 
    this.orderdao = odao; 
} 


@GET 
@Path("/orders") 
@Produces(MediaType.APPLICATION_JSON) 
public List<OrderModel> getAllOrders() { 
    return orderdao.findAll(); 
} 

@GET 
@Path("/orders/{id}") 
@Produces(MediaType.APPLICATION_JSON) 
public OrderModel getOrderById(@PathParam("id") int id) { 
    return orderdao.findById(id); 
} 
}

OrderDAO類：

public class OrderDAO extends AbstractDAO<OrderModel>{ 


public OrderDAO(SessionFactory sessionFactory) { 
    super(sessionFactory); 
} 

    public OrderModel findById(int id) { 
    return get(id); 
} 

public OrderModel create(OrderModel o) { 
    return persist(o); 
} 

public List<OrderModel> findAll() { 
    return list(namedQuery("com.yammer.dropwizard.tailor.model.OrderModel.findAll")); 
}}

Order類：

@NamedQueries({ 
@NamedQuery(
    name = "com.yammer.dropwizard.tailor.model.OrderModel.findAll", 
    query = "SELECT o FROM OrderModel o" 
), 
@NamedQuery(
    name = "com.yammer.dropwizard.tailor.model.OrderModel.findById", 
    query = "SELECT o FROM OrderModel o WHERE o.ID = :ID" 
) 
}) 
@Entity 
@Table(name = "Order") 
public class OrderModel { 

@Id 
@GeneratedValue 
@Column(name = "o_id") 
int ID; 

@Column(name = "o_shirt_quantity") 
int shirtQuantity; 
@Column(name = "o_longshirt_quantity") 
int longshirtQuantity; 
@Column(name = "o_trouser_quantity") 
int trouserQuantity; 
@Column(name = "o_coat_quantity") 
int coatQuantity; 
@Column(name = "o_deliverydate") 
Date deliveryDate; 
@Column(name = "o_orderdate") 
Date orderDate; 
@Column(name = "o_shirt_price") 
Double shirtPrice; 
@Column(name = "o_longshirt_price") 
Double longshirtPrice; 
@Column(name = "o_trouser_price") 
Double trouserPrice; 
@Column(name = "o_coat_price") 
Double coatPrice; 
@Column(name = "o_totalamount") 
Double totalAmount; 
@Column(name = "o_discount") 
Double discount; 
@Column(name = "o_advancedpayment") 
Double advancedPayment; 
@Column(name = "o_remainingpayment") 
Double remainingPayment; 
@Column(name = "o_orderstatus") 
int orderStatus; 
}

數據庫配置類：

public class databaseConfiguration extends Configuration { 

@Valid 
@NotNull 
@JsonProperty 
DataSourceFactory dbconfigurations = new DataSourceFactory(); 

public DataSourceFactory getDataSourceFactory() { 
    //return dbconfigurations; 
    Map<String,String> s=new HashMap<String,String>(); 
    s.put("hibernate.dialect","Hibernate.SQLightDialect.SQLiteDialect"); 
    dbconfigurations.setProperties(s); 
    return dbconfigurations; 
} 
}

主要服務類：

public class TailorApplication extends Application<databaseConfiguration> { 

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

private final HibernateBundle<databaseConfiguration> hibernate = new HibernateBundle<databaseConfiguration>(CustomerModel.class) { 
    { 
    @Override 
    public DataSourceFactory getDataSourceFactory(databaseConfiguration configuration) { 
     return configuration.getDataSourceFactory(); 
    } 
}; 

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

} 

@Override 
public void run(databaseConfiguration configuration, Environment environment) 
     throws Exception { 

     final OrderDAO odao = new OrderDAO(hibernate.getSessionFactory()); 

    environment.jersey().register(new TailorResource(odao)); 
} 

}

YML文件：

dbconfigurations: 
# the name of your JDBC driver 
driverClass: org.sqlite.JDBC 

# the username 
user: 

# the password 
password: 

url: jdbc:sqlite:TailorDB.db

幫助嗎？

您是否嘗試過查看數據庫的日誌？ – Magnilex

如何做到這一點？將在哪裏將日誌文件。新的所有這 –

我們甚至不知道你正在使用哪個數據庫。但閱讀這些文檔，我相信你會找到日誌文件。 – Magnilex

請務必與實體填充應用程序類：

private final HibernateBundle<AppConfiguration> hibernateBundle = new HibernateBundle<AppConfiguration>(
      // 
      // 
      //ADD ENTITIES HERE 
      // 
      // 
      Person.class 
      ,Product.class 
      ) { 
     @Override 
     public DataSourceFactory getDataSourceFactory(
       AppConfiguration configuration) { 
      return configuration.getDataSourceFactory(); 
     } 
    };

在它的面前，看起來你已經錯過了getAllOrders的@UnitOfWork註解。
話雖如此，您分享的錯誤是DW默認提供的外部消息。相反，您應該查看您的Web服務日誌以瞭解確切的錯誤和精確的堆棧跟蹤。如果你使用java -jar path/to/shaded.jar服務器my.yml在終端中運行你的服務，你應該在控制檯上看到詳細的錯誤。請分享，以便社區可以更好地幫助。
