Spring MVC & Angular - 原因：缺少 CORS 标头“Access-Control-Allow-Origin”

Question

When I try to set Content-Type:application/json I get a CORS error Reason: CORS header 'Access-Control-Allow-Origin' missing

Here is my Cors Override in Spring MVC:

@Override
public void addCorsMappings(CorsRegistry registry) {
    registry.addMapping("/**").allowCredentials(true).allowedMethods("GET", "POST", "PUT", "DELETE","OPTIONS").allowedHeaders("*").allowedOrigins("http://localhost:4200");
}

My Post API:

@RequestMapping(value = "/seanPost", method = RequestMethod.POST)
public  String post(HttpServletRequest request, @RequestBody TrackFileStatusFindForm form ) {

My Request in Angular:

options = {
headers: new HttpHeaders()
    .set('Accept', 'application/json')
    .set('Content-Type', 'application/json')
};

this.http.post(this.APP_URL + '/seanPost', JSON.stringify(this.model), this.options)
.subscribe(
    data => {
        this.postId = data;
        console.log(this.postId);
    },
    error => {
    console.log('Error occured', error);
  }
) 

My Spring project is deployed on WebLogic 12c locally and I am using https if that helps.

Thanks

试试这个：

private httpOptions = { headers: new HttpHeaders({ 'Content-Type': 'application/json' }) };
