與嵌套json彈簧消費休息

我遵循教程http：//spring.io/guides/gs/consuming-rest/消耗休息服務。本教程僅提到了單層JSON文件。但是我想分析JSON像與嵌套json彈簧消費休息

Foo: { 
fooz: 'stringdescripoers} 
bar : { 
    baz: "something", 
    etc: [[1,2],[2,0]] 
    }, 
{another object like bar}, 
{etc} 
}

根據TOT與Maven的turtorial我有以下主要類

import org.springframework.http.ResponseEntity; 
import org.springframework.web.client.RestTemplate; 

public class Application { 

    public static void main(String args[]) { 
     RestTemplate restTemplate = new RestTemplate(); 
     FeatureCollection collection = restTemplate.getForObject("http://www.trafficlink-online.nl/trafficlinkdata/wegdata/TrajectSensorsNH.GeoJSON", FeatureCollection.class); 
     System.out.println("it worked"); 
    } 
}

和我的課看起來像這樣已經成立了該項目。

import com.fasterxml.jackson.annotation.JsonIgnoreProperties; 

@JsonIgnoreProperties(ignoreUnknown = true) 
public class FeatureCollection { 

    private String type; 

    public String getType() { 
     return type; 
    } 
}

當我通過彈簧引導運行運行此我得到了我的命令行下面的結果：

tons of info,

有什麼事，我沒有看到？

檢查您的依賴關係，看看您是否有Jackson消息轉換器。您需要將您正在使用的JSON轉換爲Java對象。如果你的依賴關係比我認爲的如果你在主類的頂部使用@SpringBootApplication，Spring會自動將你正在使用的JSON轉換爲Java對象。在Eclipse中，嘗試去新建 - > Spring Starter項目 - >並選擇網頁，也許休息，然後使用該項目來消耗休息。
