Angular,CORS和Spring的问题

angularjs

我有一个基于@RestController和AngularJS的简单项目。我可以将Angular的GET请求发送到@RestController,但无法发送POST请求。我在浏览器控制台中出错:

XMLHttpRequest无法加载http:// localhost:8080 /
add
。Access-Control-Allow-
Headers不允许请求标头字段Content-Type。

我的@RestController:

@RestController
public class AngularController {
    //@Autowired
  //  PhraseService phraseService;
    Logger logger = LoggerFactory.getLogger(this.getClass());
    @RequestMapping(value = "/add", method = RequestMethod.POST)
    public void add(@RequestBody String str){
        logger.info("Added");
        logger.info(str);

    }

    @RequestMapping("/")
    public void angularController(){;
        logger.info("Request!");
    }
}

这是我的CORS过滤器:

@Component
public class SimpleCORSFilter implements Filter {

    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "x-requested-with");
        response.setHeader("Content-Type", "application/json");
        chain.doFilter(req, res);
    }

    public void init(FilterConfig filterConfig) {}

    public void destroy() {}

}

我的AngularJS控制器:

function addController($scope, $http){
    $scope.url = 'http://localhost:8080/add';
    $scope.addPhrase = function(){
        $http.post($scope.url, {"data": $scope.value});
    }
}

和index.html:

<!doctype html>
<html ng-app>
<head>
    <title>Hello AngularJS</title>
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script>
    <script src="server.js"></script>
</head>

<body>
<div ng-controller="addController">
    <form>
    <input type="text" np-model="value"/>
        <button type="button" ng-click="addPhrase()">Send!</button>
    </form>
</div>
</body>
</html>

我试图用标题:“ Content-Type”:“ application / json”解决此问题,但是它给了我错误的请求错误。

您还可以考虑使用即将发布的Spring Framework 4.2版本中提供的本地CORS支持。有关更多详细信息,请参见此博客文章

默认情况下,它配置为自动接受所有标头,因此,一旦启用带有CrossOrigin注释或Java配置的CORS支持,它便应立即起作用。
