springboot 项目中_ 利用Filter去解决跨域问题
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain) throws IOException, ServletException {
response.addHeader("Access-Control-Allow-Origin","*");
// response.addHeader("Access-Control-Allow-Methods","GET, POST, PUT, DELETE");
response.addHeader("Access-Control-Allow-Methods","*");
response.addHeader("Access-Control-Allow-Headers","Origin, Content-Type, Cookie, Accept, multipart/form-data, application/json");
response.addHeader("Access-Control-Expose-Headers", "Authorization");
response.addHeader("Access-Control-Max-Age","1800");
chain.doFilter(request, response);
}
