POST：仅在 Chrome 中出现 500 内部服务器错误答案

【问题标题】：POST: 500 Internal Server Error only in ChromePOST：仅在 Chrome 中出现 500 内部服务器错误

【问题描述】：

我有一个 Spring-Boot 后端应用程序和一个 Angular 2 前端应用程序。每次我尝试发帖时都会收到Internal Server Error 500。这只发生在 Chrome 中。所有的 get 方法都工作得很好。我不知道问题出在哪里。

Angular 中的 http 服务：

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);   
}

Spring Boot UIRestController：

@RequestMapping(method=RequestMethod.POST, value= "/addDomain", produces="application/json")
    public DomainEntity addDomain(HttpServletRequest request, HttpServletResponse response, @RequestBody DomainEntity domain, Model model);

服务：

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;
}

chome 控制台中的异常：

我查看了tomcat日志。但我仍然不明白为什么它只在 Chrome 中不起作用。在tomcat日志中出现以下错误：

【问题讨论】：

查看您的 tomcat 日志。错误 500 通常由未在该级别捕获并由容器处理的应用程序级别异常产生。

标签： java google-chrome http angular spring-boot

【解决方案1】：

您可以从网络监视器（开发工具-F12）获得（例如在 curl 中）来自 chrome 的所有请求。

如果你得到了所有 curl，你可以调查，哪个请求产生了错误。

【解决方案2】：

好的。最后我解决了这个问题。我仍然无法理解这一点，但它确实有效。

一开始我使用的是 Spring-Boot 1.3.5 版本，现在我安装了新版本的 Spring-Boot 1.4.0。

现在一切正常。这个问题也解决了图标的显示问题。因为它们也不能在 Chrome 和 IE 中工作。
