Java 带补丁动词的请求

我有两个微型服务。第一个具有符合以下代码的端点：

@RequestMapping(value = "/threshold/update/{id}/{valor}/{status}", method = RequestMethod.GET)
public Threshold updateThreshold(@PathVariable String id, @PathVariable String valor, @PathVariable Boolean status) {
    
    return thresholdQuery.updateThreshold(id,valor,status);
    
}

String url = new StringBuilder().append("http://localhost:8080/threshold/update/").append(id).append("/").append(valor).append("/").append(status).toString();
Threshold threshold = restTemplate.patchForObject(url, HttpMethod.PATCH,  Threshold.class);

@RequestMapping(value = "/threshold/update/{id}/{valor}/{status}", method = RequestMethod.PATCH)
public Threshold updateThreshold(@PathVariable String id, @PathVariable String valor, @PathVariable Boolean status)  {
    
    return thresholdQuery.updateThreshold(id,valor,status);
}

第一个向第二个微服务发出请求，代码如下：

@RequestMapping(value = "/threshold/update/{id}/{valor}/{status}", method = RequestMethod.GET)
public Threshold updateThreshold(@PathVariable String id, @PathVariable String valor, @PathVariable Boolean status) {
    
    return thresholdQuery.updateThreshold(id,valor,status);
    
}

String url = new StringBuilder().append("http://localhost:8080/threshold/update/").append(id).append("/").append(valor).append("/").append(status).toString();
Threshold threshold = restTemplate.patchForObject(url, HttpMethod.PATCH,  Threshold.class);

@RequestMapping(value = "/threshold/update/{id}/{valor}/{status}", method = RequestMethod.PATCH)
public Threshold updateThreshold(@PathVariable String id, @PathVariable String valor, @PathVariable Boolean status)  {
    
    return thresholdQuery.updateThreshold(id,valor,status);
}

第二个微服务根据以下代码接收此请求：

@RequestMapping(value = "/threshold/update/{id}/{valor}/{status}", method = RequestMethod.GET)
public Threshold updateThreshold(@PathVariable String id, @PathVariable String valor, @PathVariable Boolean status) {
    
    return thresholdQuery.updateThreshold(id,valor,status);
    
}

String url = new StringBuilder().append("http://localhost:8080/threshold/update/").append(id).append("/").append(valor).append("/").append(status).toString();
Threshold threshold = restTemplate.patchForObject(url, HttpMethod.PATCH,  Threshold.class);

@RequestMapping(value = "/threshold/update/{id}/{valor}/{status}", method = RequestMethod.PATCH)
public Threshold updateThreshold(@PathVariable String id, @PathVariable String valor, @PathVariable Boolean status)  {
    
    return thresholdQuery.updateThreshold(id,valor,status);
}

问题是我得到了以下错误：

I/O error on PATCH request for \"http://localhost:8080/threshold/update/bola/dog/true\": Invalid HTTP method: PATCH; nested exception is java.net.ProtocolException: Invalid HTTP method: PATCH"

请参阅以获得解决方法。根据以下代码：restemplate.exchange（uri、HttpMethod.PATCH、entity、Void.class）；问题是，我不需要向端点发送实体。我是否可以使用其他restTemplate方法？我改为：String aux=“”；HttpEntity requestEntity=新的HttpEntity（aux）；字符串url=new StringBuilder（）.append（“；ResponseEntity threshold=restTemplate.exchange（url，HttpMethod.PATCH，requestEntity，threshold.class）；返回threshold.getBody（）；但仍然是相同的错误。如果不发送实体，如何使用路径变量进行修补？您使用的是哪个版本的Spring Boot？我使用的是路径变量。我使用的是较新版本的Spring Boot。
