springboot配置支持跨域请求

由于对第一次使用spirngboot遇到了很多问题，springboot支持跨域请求的配置在网上找到了很多配置，但都是不能使用，后来仔细学习了解，原来是没有配配置 @WebFilter 过滤路径

import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Component;

import javax.servlet.*;
import javax.servlet.annotation.WebFilter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
@Slf4j
@WebFilter(filterName="corsFilter",urlPatterns="/*")
public class CorsFilter implements Filter {


    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        log.info("进入跨域过滤器--------------------------------------------------------------------------");
        HttpServletResponse response = (HttpServletResponse) res;
        HttpServletRequest reqs = (HttpServletRequest) req;
        response.setHeader("Access-Control-Allow-Origin",reqs.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", "x-requested-with");
        chain.doFilter(req, res);
    }

    @Override
    public void init(FilterConfig filterConfig) {

    }

    @Override
    public void destroy() {
    }
}
