[英]Spring Boot: Manage Multiple Endpoint with Rest Template?
In my Spring Boot project I have set several endpoints (which refer to some GET or POST REST API) in the application-dev.yml file.在我的 Spring Boot 项目中,我在 application-dev.yml 文件中设置了几个端点(指的是某些 GET 或 POST REST API)。
spring:
username: xxx
password: acb132
route:
source:
protocol: https://
ip: 10.xxx.y.zz/
root: "swdfr/"
paths: >
- "ofh/ert/hAFG5"
- "ofh/ert/ryt54"
I would like to manage these endpoints within a service class with a single method.我想使用单一方法在服务类中管理这些端点。 Currently I have implemented this solution:
目前我已经实施了这个解决方案:
//REST CONTROLLER
@GetMapping("/Multiple_Get")
public void manageGetEndpointsWithRestTemplate() throws Exception{
final String methodName = "manageGetEndpointsWithRestTemplate()";
try {
service.manageGetEndpointsWithRestTemplate();
} catch (final Exception e) {
this.errorLog(methodName, e);
throw e;
}
}
//SERVICE
@ResponseBody
public void manageGetEndpointsWithRestTemplate() {
final String methodName = "manageGetEndpointsWithRestTemplate()";
try {
String urlGet1 = protocol + ip + root + paths.get(0);
String urlGet2 = protocol + ip + root + paths.get(1);
HttpHeaders headers = new HttpHeaders();
headers.setBasicAuth(username, password);
HttpEntity request = new HttpEntity(headers);
try {
RestTemplate restTemplate;
if (urlGet1.startsWith("https") || urlGet2.startsWith("https")) {
restTemplate = getRestTemplateForSelfSsl();
} else {
restTemplate = new RestTemplate();
}
// GET1
ResponseEntity<String> response1 = restTemplate.exchange(urlGet1, HttpMethod.GET, request,
String.class);
HttpStatus statusCode1 = response1.getStatusCode();
logger.info("STATUS GET1: " + statusCode1);
// GET2
ResponseEntity<String> response2 = restTemplate.exchange(urlGet2, HttpMethod.GET, request,
String.class);
HttpStatus statusCode2 = response2.getStatusCode();
logger.info("STATUS GET2: " + statusCode2);
} catch (HttpStatusCodeException e) {
logger.error(e.getMessage());
}
} catch (Exception e) {
logger.error(e.getMessage());
}
}
public RestTemplate getRestTemplateForSelfSsl()
throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
TrustStrategy acceptingTrustStrategy = (X509Certificate[] x509Certificates, String s) -> true;
SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy)
.build();
SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext, new NoopHostnameVerifier());
CloseableHttpClient httpClient = HttpClients.custom().setSSLSocketFactory(csf).build();
HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
requestFactory.setHttpClient(httpClient);
RestTemplate restTemplate = new RestTemplate(requestFactory);
return restTemplate;
}
I would like to use a single method making it as generalizable as possible especially if I have to manage a large number of endpoints.我想使用一种方法使其尽可能通用,特别是如果我必须管理大量端点。 Do you have any ideas?
你有什么想法? Thanks in advance
提前致谢
You can iterate over all the paths
and execute the common code, considering you are doing GET
request for all.考虑到您正在为所有
paths
执行GET
请求,您可以遍历所有paths
并执行公共代码。
@ResponseBody
public void manageGetEndpointsWithRestTemplate() {
final String methodName = "manageGetEndpointsWithRestTemplate()";
try {
paths.forEach(path -> {
String urlGet = protocol + ip + root + path;
HttpHeaders headers = new HttpHeaders();
headers.setBasicAuth(username, password);
HttpEntity request = new HttpEntity(headers);
try {
RestTemplate restTemplate = urlGet.startsWith("https") ? getRestTemplateForSelfSsl() : new RestTemplate();
ResponseEntity<String> response = restTemplate.exchange(urlGet, HttpMethod.GET, request,
String.class);
HttpStatus statusCode = response.getStatusCode();
logger.info("STATUS GET - {} : {}", urlGet, statusCode);
} catch (HttpStatusCodeException e) {
logger.error(e.getMessage());
}
});
} catch (Exception e) {
logger.error(e.getMessage());
}
}
In case you're gonna use POST
or any other HTTP methods, mention in application-dev.yml
file along with the paths
.如果您要使用
POST
或任何其他 HTTP 方法,请在application-dev.yml
文件中与paths
一起提及。 Add few extra logic to determine the HTTP.XXX
before passing into restTemplate.exchange()
.在传递到
restTemplate.exchange()
之前添加一些额外的逻辑来确定HTTP.XXX
。
