私はSpring-BootバックエンドアプリケーションとAngular 2 Frontend-Applicationを持っています。 投稿するたびにInternal Server Error 500が届きます。これはChromeでのみ発生します。すべてのgetメソッドは絶対にうまく動作します。私はどこに問題があるのか分からない。角度でPOST：Chromeの内部サーバーエラー：
HTTPサービス：
addDomain(domainEntity:DomainEntity){
let headers = new Headers({
'Content-Type': 'application/json'
});
let options = new RequestOptions({
headers: headers
});
let body = JSON.stringify(domainEntity)
return this._http.post(this.baseURL+'addDomain', body, options);
}
春ブーツUIRestController：
@RequestMapping(method=RequestMethod.POST, value= "/addDomain", produces="application/json")
public DomainEntity addDomain(HttpServletRequest request, HttpServletResponse response, @RequestBody DomainEntity domain, Model model);
サービス：丁目コンソールで
public DomainEntity addDomain(DomainEntity domain, Model model) {
String url = this.webServiceProperties.webUserBaseURL+"addDomain/";
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
HttpEntity<DomainEntity> entity = new HttpEntity<DomainEntity>(domain, headers);
try{
RestTemplate restTemplate = new RestTemplate();
ResponseEntity<DomainEntity> responseEntity= restTemplate.exchange(
UriComponentsBuilder.fromHttpUrl(url).build().encode().toUri(),
HttpMethod.POST,
entity,
DomainEntity.class);
return responseEntity.getBody();
}catch(Exception e1){
e1.printStackTrace();
}
return null;
}
が例外：

私はtomcatログを見てきました。しかし、私はまだそれがクロームではうまくいかない理由を理解できません。エラー以下の私は、Tomcatのログに取得する：

tomcatログを見てください。エラー500は、通常、そのレベルでキャッチされずにコンテナによって処理されたアプリケーションレベルの例外によって生成されます。 – AlexR
