如何添加跨源資源共享在我的Java FIE

Question

我寫了這是不正確

HttpClient httpClient = HttpClientBuilder.create().header("Access-Control-Allow-Origin", "*") 
       .header("Access-Control-Allow-Methods", "GET, POST, DELETE, PUT") 
       .allow("OPTIONS").build();

您可以編寫組件類CORS起源過濾

@Component 
public class CorsFilterConfiguration 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, PUT, PATCH, OPTIONS, DELETE"); 
     response.setHeader("Access-Control-Max-Age", "3600"); 
     response.setHeader("Access-Control-Allow-Headers", "x-requested-with, Content-Type, authToken"); //TODO: Fix 'token' to 'OAuth'/'SAML' header. 
     chain.doFilter(req, res); 
    } 
    public void init(FilterConfig filterConfig) { 
    } 
    public void destroy() { 
    } 
}
