具有可選實體篩選功能的Jersey在沒有選擇URI的情況下停止響應

Question

我試圖通過Entity Data Filtering Dynamic and Configurable Query Parameters來改進我的服務。所有資源都在GET上正確響應。當我執行POST方法時，服務器凍結。 App Server內存不足。

問題：有人知道爲什麼會發生這種情況？我做錯了什麼？

編輯：使用LoggingFilter.class激活它可能在其他情況下看到確認響應，而不僅僅是使用POST方法。

• 作品

  （GET）/休息/結構域/實體/ 1？選擇= ID，名字

• 服務器停止響應

  （GET）/休息/ domain/Entity/1

在第二個請求中，服務器收到它並且LoggingFilter顯示狀態碼200.所以我認爲這個問題在編組器上。

CONFIG：

該應用程序部署在WSO2 AS 5.2.1。

ApplicationConfig類：

@javax.ws.rs.ApplicationPath("rest") 
public class ApplicationConfig extends ResourceConfig { 

    public ApplicationConfig() { 

     property(ServerProperties.BV_SEND_ERROR_IN_RESPONSE, true); 
     property(ServerProperties.BV_DISABLE_VALIDATE_ON_EXECUTABLE_OVERRIDE_CHECK, true); 
     property(MarshallerProperties.BEAN_VALIDATION_MODE, BeanValidationMode.NONE); 

     register(SelectableEntityFilteringFeature.class); 
     property(SelectableEntityFilteringFeature.QUERY_PARAM_NAME, "select"); 

     register(new MoxyJsonConfig().setFormattedOutput(true).resolver()); 

    } 
}

Answer 1

一些調試的同事發現後發生，因爲我有雙向實體。

比方說，我們有客戶E地址：

@Entity 
public class Customer { 

    @Id 
    private long id; 

    @OneToOne(mappedBy="customer", cascade={CascadeType.ALL}) 
    private Address address; 

} 

@Entity 
public class Address implements Serializable { 

    @Id 
    private long id; 

    @OneToOne 
    @JoinColumn(name="ID") 
    @MapsId 
    @XmlInverseReference(mappedBy="address") 
    private Customer customer; 

} 

在這種情況下，可選擇的過濾器會忽略@XmlInverseReference當它試圖建立ObjectGraph和它去OOM。
