我在我的代碼中使用jsonschema2pojo時遇到問題。所以，我用jsonschema2pojo發生器（http://www.jsonschema2pojo.org/），從這個URL生成POJO的：http://store.steampowered.com/api/appdetails/?appids=10 帶URL的jsonschema2pojo不起作用

最後，我在一個包中「模式」創建所有這些類。然後在我嘗試用它來讀取鏈接JSON，但我得到異常：

Exception in thread "main" java.lang.NullPointerException 
    at controller.View.main(View.java:26)

我不明白爲什麼。這裏是代碼我怎樣才能做到這一點：

public class View { 
private static String urlStr = "http://store.steampowered.com/api/appdetails/?appids=10"; 

public static void main(String[] args) { 

    ObjectMapper objectMapper = new ObjectMapper(); 

    try { 
     Game game = objectMapper.readValue(new URL(urlStr), Game.class); 

     System.out.println(game.getData().getName()); 
    } catch (MalformedURLException e) { 
     e.printStackTrace(); 
    } catch (JsonParseException e) { 
     e.printStackTrace(); 
    } catch (JsonMappingException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 


}

}

的Game.class是finall類，我在發電機爲「類名」設置。

有什麼不對？我怎樣才能從這個鏈接獲取所有這些數據？

在行家我配置它這樣的：

<plugin> 
      <groupId>org.jsonschema2pojo</groupId> 
      <artifactId>jsonschema2pojo-maven-plugin</artifactId> 
      <version>0.4.18</version> 
      <configuration> 
       <sourceType>jsonschema</sourceType> 
       <outputEncoding>${project.build.sourceEncoding}</outputEncoding> 
       <outputDirectory>${project.build.directory}/generated-sources</outputDirectory> 
       <annotationStyle>jackson2</annotationStyle> 
       <generateBuilders>true</generateBuilders> 
       <initializeCollections>true</initializeCollections> 
      </configuration> 
      <executions> 
       <execution> 
        <id>generate-game</id> 
        <goals> 
         <goal>generate</goal> 
        </goals> 
        <configuration> 
         <targetPackage>model.game</targetPackage> 
         <sourceDirectory>${basedir}/src/main/resources/schema/game</sourceDirectory> 
        </configuration> 
       </execution> 
      </executions> 
     </plugin>

正如我所說的，所有的類都是在的src/main/java和包裝 '模式'，我的模式是在SR /主/資源/模式/在文件「遊戲」

我的模式是這樣的：

     ] 
    } 
    }, 
    "required": [ 
    "10" 
    ] 
}

有了這個配置，我可以用這條線，而不是之前的System.out.println讀取所有數據：

System.out.println(objectMapper.writeValueAsString(game));

現在我可以看到完整的json字符串，但是如何使用'game.getData（）。getName（）'等來讀取它？

您提供的JSON模式將「10」定義爲包含其他所有內容的頂級屬性。

{ 
    "type": "object", 
    "required":false, 
    "javaType":"model.Game", 
    "properties": { 
    "10": { 
     "id": "10", 
     "type": "object", 
     "properties": { 
     "success": { 
      "id": "success", 
      "type": "boolean" 
     }, 
     "data": { 
      "id": "data", 
      "type": "object", 
      "properties": { 
      "type": { 
       "id": "type", 
       "type": "string" 
      }, 
      "name": { 
       "id": "name", 
       "type": "string" 
      }, 
...

jsonschema2pojo讀取模式，並生成一個名爲_10作爲模型的部件分類。您可以在_10.java中的generated-sources目錄中找到它。

@JsonInclude(JsonInclude.Include.NON_NULL) 
@Generated("org.jsonschema2pojo") 
@JsonPropertyOrder({ 
    "success", 
    "data" 
}) 
public class _10 {

我不知道這是模式中的故意。如果它是故意的，那麼你需要像這樣訪問這個名字。

System.out.println(game.get10().getData().getName());

在做出更改後，我能夠正常工作。

編輯：它看起來這些JSON消息應該有一個變量ID作爲包含其他所有內容的頂級密鑰，所以我們需要處理這個有點不同。我們可以概括模式，以便它不是特定於特定ID，然後我們可以使用兩個步驟來解析消息。首先，我們將使用[ObjectMapper#readValue]（https://fasterxml.github.io/jackson-databind/javadoc/2.5/com/fasterxml/jackson/databind/ObjectMapper.html#readValue(java.net.URL，com.fasterxml.jackson.core.type.TypeReference））將整個消息解析爲Map<String, Object>。我們預計頂層地圖將包含一個元素，與我們請求的文檔的ID相對應，其值將是包含我們感興趣的值的子地圖。然後，我們將傳遞該子地圖通過[ObjectMapper#convertValue]（https://fasterxml.github.io/jackson-databind/javadoc/2.5/com/fasterxml/jackson/databind/ObjectMapper.html#convertValue(java.lang.Object，java.lang.Class））來獲得我們想要的Game對象。

此外，我需要做出一個其他更改到架構。我刪除了linux_requirements屬性。這是因爲看文檔10與文檔219，它是前者中的一個對象，後者是一個數組。對於文檔219，解析器不知道如何理解數組，因爲我們期待着一個對象。從API返回的數據如此不一致，這很奇怪。您可能需要對模式進行一些修改，以使其完全適用於從該API返回的所有可能的JSON文檔。

我已將所有代碼放入GitHub repository。您可以獲取該代碼，構建它並運行它來查看它的工作情況。然後，你可以進一步適應你的需求。

但是您是否嘗試在URL中使用其他ID如果此clas _10也適用於id = 219？ – ullQuiorra

我試圖做到像你一樣，但我得到了異常：無法識別的字段「steam_appid」（Class model.Data），未標記爲可忽略 – ullQuiorra

如果ID（這是變量）預期作爲格式中的鍵，那麼你可能考慮做一個兩步的過程，將整個東西解析成一個沒有特定數據綁定的原始地圖，然後拉出與該鍵相對應的子地圖，然後通過序列化返回到JSON並反序列化來使該子地圖往返通用模式，它沒有指定「10」或任何其他特定的ID。 –

而不是嘗試使用properties對包含ID的對象建模，請使用additionalProperties。假設頂層類型包含了幾場比賽，你可以嘗試的東西代替

{ 
    "type": "object", 
    "required":false, 
    "javaType":"model.Game", 
    "properties": { 
    "10": { 
     "id": "10", 
     "type": "object", 
     ... 
    } 
    } 
}

像

{ 
    "type": "object", 
    "required":false, 
    "javaType":"model.Games", 
    "additionalProperties": { 
     "id": "game", 
     "type": "object", 
     "javaType": "model.Game" 
     ... 
    } 
}

這應該做出model.Games類型與像public Map<String, Game> getAdditionalProperties()的方法。
