我有一个带有spring-rest api的spring客户端，该客户端受keycapture保护。我正试图使用另一个客户端的keycaptureresttemplate来调用它，这是一个没有安全性的纯java代码。我正在从java客户端获取密钥斗篷访问令牌，并将其设置在rest url的头中。它无法初始化key斗篷resttemplate。
我为什么要面对这个问题。
//下面是使用keycaparesttemplate访问spring-url的代码。我添加了对keycloack适配器的依赖，并在我的java类中添加了bean。
restTemplate.getForObject(<restapiURL>, class1, requestData);
//以下是我用于从密钥斗篷获取访问令牌的代码
MultiValueMap<String,String> requestMap = new LinkedMultiValueMap<String,String>();
requestMap.add("client_id", "employee-service");
requestMap.add("username", "rachel");
requestMap.add("password", "rachel");
requestMap.add("grant_type", "password");
requestMap.add("client_secret", "cccebf50-3f28-4af2-8716-c4bfcfe6f5e7");
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
HttpEntity<MultiValueMap<String, String>> requestData = new HttpEntity<>(requestMap, headers);
RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new FormHttpMessageConverter());
String restApiurl = "http://localhost:8080/auth/realms/dev/protocol/openid-connect/token" ;
return restTemplate.postForObject(restApiurl, requestData, AccessTokenResponse.class);

关于从客户端1调用客户端2，首先从客户端1获取AUTHORIZATION标头，并将其包含在中以查询到客户端2。类似：
// Client 1
@RequestMapping(value = "/some-api", method = RequestMethod.POST) // or GET
public ResponseEntity<SomeDto> processSomething(@RequestHeader(HttpHeaders.AUTHORIZATION) String authHeader) {
HttpHeaders headers = new HttpHeaders();
if (authHeader != null) {
headers.add(AUTHORIZATION_HEADER, authHeader);
}
SomeDto dto = someService.processSomething(headers);
return ResponseEntity.ok(dto);
}
// client1 someService
RestTemplate restTemplate = new RestTemplate();
public List<YourDto> getBla(HttpHeaders headers) {
String path = "/client2/api";
UriComponentsBuilder builder = UriComponentsBuilder.fromUriString(path);
String url = builder.toUriString();
try {
HttpEntity<?> requestEntity = new HttpEntity<>(headers);
ResponseEntity<String> response = restTemplate.exchange(url, HttpMethod.GET, requestEntity, String.class);
if (response.getStatusCode().is2xxSuccessful()) {
return objectMapper.readValue(response.getBody(), new TypeReference<List<YourDto>>() {}).apply(response);
}
log.error("Error response while getting blabla", response);
throw new InternalServerException("");
} catch (HttpRestClientException | ResourceAccessException exp) {
log.error("Exception while getting blabla", exp);
throw new InternalServerException("");
}
}
我现在收到401个未经授权的错误。请检查下面的代码片段。Client2，它是一个spring-rest api。spring的RestController，这些api受keycapture保护。当我从浏览器中点击任何一个api时，我会得到一个keycapture登录页面，在成功验证后，它会返回response.package com.dbaas.controller；

}
return null;

employeeList.add(emp1);
employeeList.add(emp2);

return employeeList;
