Spring boot项目，上传跨域问题解决办法

Spring boot项目，上传是个单独的服务，用了Nginx转发，其它项目上传文件都通过这个项目的接口，遇到了跨域问题，解决办法是：

import org.springframework.stereotype.Component;
import javax.servlet.*;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@Component

public class SimpleCORSFilter implements Filter {

    @Override
    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");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "access-control-allow-origin, authority, content-type, version-info, X-Requested-With");
        chain.doFilter(req, res);
    }
    @Override
    public void init(FilterConfig filterConfig) {
    }
    @Override
    public void destroy() {
    }

}
