彈簧恢復模板連接重置

Question

我試圖在this指南中使用Spring設施的REST服務，但是我遇到了連接問題。 我想用GET方法來訪問REST服務

http://date.jsontest.com/

我寫這段代碼消費服務

package pack; 
import static org.junit.Assert.assertTrue; 

import java.util.HashMap; 
import java.util.Map; 

import javax.annotation.Generated; 

import org.junit.Test; 
import org.springframework.web.client.RestTemplate; 

import com.fasterxml.jackson.annotation.JsonAnyGetter; 
import com.fasterxml.jackson.annotation.JsonAnySetter; 
import com.fasterxml.jackson.annotation.JsonInclude; 
import com.fasterxml.jackson.annotation.JsonProperty; 
import com.fasterxml.jackson.annotation.JsonPropertyOrder; 


public class RestUtilityTest { 

    @JsonInclude(JsonInclude.Include.NON_NULL) 
    @JsonPropertyOrder({ 
     "time", 
     "milliseconds_since_epoch", 
     "date" 
    }) 
    public class DateTime { 

     @JsonProperty("time") 
     private String time; 
     @JsonProperty("milliseconds_since_epoch") 
     private Integer milliseconds_since_epoch; 
     @JsonProperty("date") 
     private String date; 
     private Map<String, Object> additionalProperties = new HashMap<String, Object>(); 

     @JsonProperty("time") 
     public String getTime() { 
      return time; 
     } 

     @JsonProperty("time") 
     public void setTime(String time) { 
      this.time = time; 
     } 

     @JsonProperty("milliseconds_since_epoch") 
     public Integer getMilliseconds_since_epoch() { 
      return milliseconds_since_epoch; 
     } 

     @JsonProperty("milliseconds_since_epoch") 
     public void setMilliseconds_since_epoch(Integer milliseconds_since_epoch) { 
      this.milliseconds_since_epoch = milliseconds_since_epoch; 
     } 

     @JsonProperty("date") 
     public String getDate() { 
      return date; 
     } 

     @JsonProperty("date") 
     public void setDate(String date) { 
      this.date = date; 
     } 

     @JsonAnyGetter 
     public Map<String, Object> getAdditionalProperties() { 
      return this.additionalProperties; 
     } 

     @JsonAnySetter 
     public void setAdditionalProperty(String name, Object value) { 
      this.additionalProperties.put(name, value); 
     } 

    } 

    @Test 
    public void getTest() 
    { 

     RestTemplate restTemplate = new RestTemplate(); 
     DateTime datetime = restTemplate.getForObject("http://date.jsontest.com", DateTime.class); 

     assertTrue(datetime != null); 

    } 

} 

應用程序引發以下異常堆棧

我試過REST調用兩個不同的網絡連接，所以這不是一個網絡連接問題;此外，如果我從瀏覽器訪問服務，我可以正確地得到響應。

可能是什麼問題？

謝謝您提前

解決。問題被綁定到網絡連接。我所屬的網絡是防火牆和代理。 現在我試圖瞭解如何使用防火牆網絡完成任務（這是我的公司之一）。
