springboot中新增一个过滤器如下：

package com.rtpksps.kss.config;
import org.springframework.stereotype.Component;
import javax.servlet.*;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

/**
 * @author Administrator
 * @title: OriginFilter
 * @projectName rtpksps-kss
 * @description: TODO
 * @date 2019/9/29 0029下午 15:52
 */
@Component
public class OriginFilter implements Filter {
    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) servletResponse;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE,PUT");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "x-requested-with");
        filterChain.doFilter(servletRequest, servletResponse);
    }

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {


    }

    @Override
    public void destroy() {

    }
}


在接口中指定需要的方法类型
