Post resttemplate in Spring does not work and get works - spring

Question

This is my client code:
#GetMapping("/")
public String home() throws NoSuchAlgorithmException, CertificateException, FileNotFoundException, IOException, KeyStoreException, KeyManagementException, UnrecoverableKeyException, RestClientException, URISyntaxException {
String url = "https://localhost:8483/secure-server/hola";
//
// KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
//
// keyStore.load(new FileInputStream(new File("client-keystore.jks")), "secret".toCharArray());
//
// System.out.println(url);
// SSLConnectionSocketFactory socketFactory = new SSLConnectionSocketFactory(
// new SSLContextBuilder()
// .loadTrustMaterial(null, new TrustSelfSignedStrategy())
// .loadKeyMaterial(keyStore, "secret".toCharArray())
// .build(),
// NoopHostnameVerifier.INSTANCE);
//
// HttpClient httpClient = HttpClients.custom().setSSLSocketFactory(socketFactory).build();
//
// ClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory(httpClient);
// RestTemplate restTemplate = new RestTemplate(requestFactory);
// String record = restTemplate.getForObject(url, String.class);
////
//
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
HttpEntity<String> request = new HttpEntity<>("", headers);
return restTemplate.exchange(url, HttpMethod.POST, request , String.class ).getBody();
//
// ResponseEntity<String> resp = restTemplate.exchange(
// new URI(url), HttpMethod.GET,
// httpEntity, String.class);
//return model.getBody();
}
#Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) throws Exception {
char[] password = "secret".toCharArray();
SSLContext sslContext = SSLContextBuilder.create()
.loadKeyMaterial(keyStore("client-keystore.jks", password), password)
.loadTrustMaterial(new File("client-truststore.jks"),"secret".toCharArray()).build();
HttpClient client = HttpClients.custom().setSSLContext(sslContext).build();
return builder
.requestFactory(new HttpComponentsClientHttpRequestFactory(client))
.build();
}
private KeyStore keyStore(String file, char[] password) throws Exception {
KeyStore keyStore = KeyStore.getInstance("jks");
File key = ResourceUtils.getFile(file);
try (InputStream in = new FileInputStream(key)) {
keyStore.load(in, password);
}
return keyStore;
}
This is my server code with the two methods post and get, the get is working but post is not working:
#RestController
public class HomeRestController {
#PostMapping("/hola")
public String home(Principal principal) {
return String.format("Hello %s!", principal.getName());
}
#GetMapping("/holaa")
public String homee(Principal principal) {
return String.format("Hello %s!", principal.getName());
}
}
I have this is my YML with the mutual authentication configuration:
server:
context-path: /${spring.application.name}
port: 8483
ssl:
key-store: server-keystore.keystore
key-store-password: pass123
key-alias: default
trust-store: server-truststore.jks
trust-store-password: secret
enabled: true
client-auth: need
Calling the getMaping it works, but calling the postMaping it returns to me 403.
The keystore and trustore are configured and are OK.
And in my security configuration I have:
#EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().anyRequest().authenticated().and().x509()
.subjectPrincipalRegex("CN=(.*?)(?:,|$)").userDetailsService(userDetailsService());
}
#Override
#Bean
public UserDetailsService userDetailsService() {
return (username -> {
return new User(username, "",
AuthorityUtils.commaSeparatedStringToAuthorityList("ROLE_USER"));
});
}
}
Why my post calling does not work?
