我想使用 RestTemplate 通过我自己的应用程序中的端点执行GET，但是当我这样做时，出现以下错误/异常：
o.apache.coyote.http11.Http11Processor : Error parsing HTTP request header
java.io.EOFException: null
at org.apache.tomcat.util.net.NioEndpoint$NioSocketWrapper.fillReadBuffer(NioEndpoint.java:1229) ~[tomcat-embed-core-9.0.27.jar:9.0.27]
这是我的端点类：
@RequestMapping("/wakeup")
@RestController
public class WakeUpResource {
private Logger logger = LoggerFactory.getLogger(ApplicationWakeUpScheduller.class);
@GetMapping
public @ResponseBody String wakeup() {
return "I am awake!";
}
}
这是我的Application类，其中的端点称为：
@SpringBootApplication
public class NovaVidaBudgetApplication implements CommandLineRunner {
public static void main(String[] args) {
SpringApplication.run(NovaVidaBudgetApplication.class, args);
}
@Override
public void run(String... args) throws Exception {
wakeUpApplication();
}
public void wakeUpApplication() {
HttpHeaders headers = getHttpHeaders();
final RestTemplate restTemplate = new RestTemplate();
final String url = "http://localhost:8080/wakeup";
HttpEntity<String> requestEntity = new HttpEntity<>(headers);
restTemplate.exchange(url, HttpMethod.GET, requestEntity, String.class);
}
private HttpHeaders getHttpHeaders() {
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.TEXT_PLAIN);
return headers;
}
}
当我立即执行此应用程序时，将调用终结点并得到 200 状态响应，但是这种令人讨厌的EOFException也会发生。这是包含异常的完整日志：

我认为下面的错误是一个提示，但是我不知道标头出了什么问题
o.apache.coyote.http11.Http11Processor : Error parsing HTTP request header
有什么想法吗？
预先感谢
