配置过滤器

import com.lenovo.ruler.manage.system.filter.AbsoluteSendRedirectFilter;
    import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
    import org.springframework.boot.web.servlet.FilterRegistrationBean;
    import org.springframework.context.annotation.Bean;
    import org.springframework.stereotype.Component;
    
    @Component
    @ConditionalOnProperty(name = "server.scheme.chanage.enabled", havingValue = "true") // 开启注解才会启动
    public class RedirectFilterConfig {
    
        @Bean
        public FilterRegistrationBean registFilter() {
    
            FilterRegistrationBean registration = new FilterRegistrationBean();
            registration.setFilter(new AbsoluteSendRedirectFilter());
            registration.addUrlPatterns("*");
            registration.setName("filterRegistrationBean");
            registration.setOrder(1);
            return registration;
        }
    
    }

import org.springframework.web.filter.OncePerRequestFilter;
    
    import javax.servlet.FilterChain;
    import javax.servlet.ServletException;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import java.io.IOException;
    
    public class AbsoluteSendRedirectFilter extends OncePerRequestFilter {
    
        @Override
        protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
            RedirectResponseWrapper redirectResponseWrapper = new RedirectResponseWrapper(request, response);
            filterChain.doFilter(request, redirectResponseWrapper);
        }
    
    }

http重写成https

import org.apache.commons.lang.StringUtils;
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import javax.servlet.http.HttpServletResponseWrapper;
    import java.io.IOException;
    import java.net.URI;
    import java.net.URISyntaxException;
    
    public class RedirectResponseWrapper extends HttpServletResponseWrapper {
    
        private final HttpServletRequest request;
    
        public RedirectResponseWrapper(final HttpServletRequest inRequest, final HttpServletResponse response) {
            super(response);
            this.request = inRequest;
        }
    
        @Override
        public void sendRedirect(final String pLocation) throws IOException {
    
            if (StringUtils.isBlank(pLocation)) {
                super.sendRedirect(pLocation);
                return;
            }
    
            try {
                final URI uri = new URI(pLocation);
                if (uri.getScheme() != null) {
                    super.sendRedirect(pLocation);
                    return;
                }
            } catch (URISyntaxException ex) {
                super.sendRedirect(pLocation);
            }
    
            // !!! FIX Scheme  !!!
            String finalurl = "https://" + this.request.getServerName();
            if (request.getServerPort() != 80 && request.getServerPort() != 443) {
                finalurl += ":" + request.getServerPort();
            }
            finalurl += pLocation;
            super.sendRedirect(finalurl);
        }
    
    }
