Spring Boot Angular 2和Access-Control-Allow-Origin在服务器上不起作用

Question

这里是我的过滤器：

@Component
public class MyCorsFilter implements Filter {

    public MyCorsFilter() {
        System.out.println("init filter corsssss");
    }

    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {

        HttpServletRequest request = (HttpServletRequest) req;
        HttpServletResponse response = (HttpServletResponse) res;

        response.setHeader("Access-Control-Allow-Origin", request.getHeader("Origin"));
        response.setHeader("Access-Control-Allow-Credentials", "true");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "Content-Type, Accept, X-Requested-With, remember-me");

        chain.doFilter(req, res);
    }

    @Override
    public void init(FilterConfig filterConfig) {
    }

    @Override
    public void destroy() {
    }
}

我也有同样的问题。

在控制器中尝试此操作：

@Context
private HttpServletResponse servletResponse;

private void allowCrossDomainAccess() {
    if (servletResponse != null) {
        servletResponse.setHeader("Access-Control-Allow-Origin", "*");
    }
}

然后在您的帖子/获取方法中：

@CrossOrigin
@RequestMapping(value = "/login", method = RequestMethod.POST, consumes = "application/json")
public boolean loginController(@RequestBody User user) throws JSONException, NoSuchAlgorithmException, UnsupportedEncodingException {

    allowCrossDomainAccess();  
    return userService.login(user);
}
