spring boot 跨域问题处理

1、

public class SimpleCrossFilter implements Filter {

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }
    @Override
    public void doFilter(ServletRequest request, ServletResponse servletResponse, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) servletResponse;
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE,PUT");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "token_id");
        chain.doFilter(request, response);
    }
    @Override
    public void destroy() {
    }

}

2、

application.java 添加

    @Bean
    public SimpleCrossFilter simpleCORSFilter() {
        return new SimpleCrossFilter();
    }

3、

@CrossOrigin(origins = "*")
