完美解决Spring Boot前端的Access-Control-Allow-Origin跨域问题

@WebFilter(filterName = "CorsFilter ")
public class CorsFilter implements Filter {
    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        HttpServletRequest reqs = (HttpServletRequest) req;
        // response.setHeader("Access-Control-Allow-Origin",reqs.getHeader("Origin"));
        response.setHeader("Access-Control-Allow-Origin","*");
        response.setHeader("Access-Control-Allow-Credentials", "true");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, PATCH, DELETE, PUT");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
        chain.doFilter(req, res);
    }
    @Override
    public void init(FilterConfig filterConfig) {}
    @Override
    public void destroy() {}
}

@Configuration
public class CorsConfig extends WebMvcConfigurerAdapter {
	@Override
	public void addCorsMappings(CorsRegistry registry) {
		registry.addMapping("/**").allowedOrigins("*")
				.allowedMethods("GET", "HEAD", "POST","PUT", "DELETE", "OPTIONS")
				.allowCredentials(true).maxAge(3600);
	}
