Spring Boot 處理前端跨域問題

springboot 處理跨域的其中一種方式

import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class MyCorsFilter implements Filter {

    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain)

        chain.doFilter(req, res);
    }

    @Override

    @Override

    }
}
