在JAVA中使用HttpURLConnection的PATCH请求

Question

如何使用JAVA中的HttpURLConnection执行RESTHeart API的PATCH请求。它将405返回为状态。

public class TestRestHeartUpdate{ 
public static void main(String[] args) throws Exception{ 

URL url; 
url = new 
URL("http://127.0.0.1:8080/testDB1/col1/5967c13e61f73b88018db783"); 

HttpURLConnection hc; 
hc = (HttpURLConnection) url.openConnection(); 
hc.setDoInput(true); 
hc.setDoOutput(true); 
hc.setRequestMethod("POST"); 
hc.setRequestProperty("X-HTTP-Method-Override", "PATCH"); 

hc.setRequestProperty("Content-Type","application/hal+json"); 
hc.setRequestProperty("Accept","application/hal+json"); 
hc.setInstanceFollowRedirects(false); 
hc.setRequestProperty("If-Match","5967c28f42483b1c3dbedc54"); 
hc.setUseCaches(false); 
hc.connect(); 

byte[] opB = " {'rating':'VeryGood'}".getBytes("UTF-8"); 
OutputStream os = hc.getOutputStream(); 
os.write(opB); 
System.out.println(hc.getResponseCode()); 
} 
}

HTTP代码405表示方法不允许。这表明您的Web服务器不允许PATCH请求，并且您需要将其配置为接受PATCH方法类型。
