Vue中axios访问 后端跨域问题

public class AllowOriginFilter implements Filter {
     @SuppressWarnings("unused")
    public void doFileter(ServletRequest req,ServletResponse res,FilterChain chain) throws IOException,ServletException{
    HttpServletResponse response = (HttpServletResponse) res;
    HttpServletRequest request=(HttpServletRequest)req;
    response.setHeader("Access-Control-Allow-Origin", "*"); // 设置允许所有跨域访问 
    response.setHeader("Access-Control-Allow-Methods", "POST,GET,PUT,OPTIONS,DELETE");
    response.setHeader("Access-Control-Max-Age", "3600");
    response.setHeader("Access-Control-Allow-Headers", "Origin,X-Requested-With,Content-Type,Accept,Authorization,token");
    response.setHeader("Access-Control-Allow-Credentials", "true");
    chain.doFilter(req,res);
  }
    public void init(FilterConfig filterConfig) {}
    public void destroy() {}
}
