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 = "*")
