在我的android应用程序中，我正在使用rest模板进行服务调用，但问题是当任何服务被调用时，我将遇到错误。服务未连接到服务器。

到现在为止没有错误，并且我所有的服务都可以正常工作，但是突然出现了这个错误，不允许我继续操作。下面是对服务器的调用。
public List<Employee> getAllEmployeeList() {
String plainClientCredentials="************************";
String base64ClientCredentials = new String(Base64.encode(plainClientCredentials.getBytes(),Base64.NO_WRAP));
HttpHeaders headers = new HttpHeaders();
headers.add("Authorization", "Basic " + base64ClientCredentials);
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
HttpEntity<String> entity = new HttpEntity<String>(headers);
ResponseEntity<String> restRes = restTemplate.exchange(LoginActivity.strMainUrl+"protected/users/getAllEmployeeList", HttpMethod.GET, entity, String.class);
System.out.println("restRes : "+restRes);
if (restRes.getStatusCode() == HttpStatus.OK) {
AppBackupCache.checkToken = 200;
String resBody = restRes.getBody();
Type listType = new TypeToken<List<Employee>>() {}.getType();
List<Employee> employeeList = new ArrayList<Employee>();
schoolList = gson.fromJson(resBody,listType);
return employeeList;
} else if(restRes.getStatusCode() == HttpStatus.UNAUTHORIZED) {
AppBackupCache.checkToken = 401;
return null;
} else {
AppBackupCache.checkToken = 402;
return null;
}
}
以上代码到目前为止运行良好，并且突然出现错误并且该错误不起作用，在每个服务调用中都发生相同的情况。我的代码有什么问题。 下面是我从活动类调用其他服务的方式。

当我在名为AttachmentActivity的活动上注释了oncreate代码时，loginActivity上的错误消失了。该错误显示在LoginActivity上，因为从那里开始第一个Web服务调用，如果我注释了此行this.employeeList = serverAuthenticateService.getAllEmployeeList();，则该错误可能出现在下一个活动的下一个网络服务调用中。

您已经错过了在类路径中包含spring-web的问题。将其添加到您的Gradle文件中，它应该可以工作。
compile "org.springframework:spring-web:<!--your spring version-->"
