SpringBoot-JAVA：将客户机参数添加到URL

我想在我的URL中添加一个客户端名称参数，因此当我收到如下链接时： 我想测试我的客户机是否存在于数据库中，如果存在，我希望客户机接收我网站的内容，就像他调用：

我尝试使用如下所示的包装器：

import org.apache.commons.lang.StringUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
public class ChangeURIPathFilter implements Filter {
    private final Logger log = LoggerFactory.getLogger(ChangeURIPathFilter.class);
    RequestWrapper modifiedRequest = null;
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {}
    @Override
    public void destroy() {}
    @Override
    public void doFilter(ServletRequest request, ServletResponse response,
        FilterChain chain) throws IOException, ServletException {
        HttpServletRequest httpRequest = (HttpServletRequest) request;
        String contextPath = ((HttpServletRequest) request).getContextPath();
        String requestURI = httpRequest.getRequestURI();
        modifiedRequest = new RequestWrapper(httpRequest, "/");
        chain.doFilter(modifiedRequest, response);
    }
    class RequestWrapper extends HttpServletRequestWrapper {
        private String originalValue;
        public RequestWrapper(HttpServletRequest request) {
            super(request);
        }
        @Override
        public String getRequestURI() {
            String originalURI = super.getRequestURI();
            String s = super.getRequestURI();
            if (StringUtils.equals(s, originalValue)) return originalValue
                .replaceAll("client1", "");
            else return s;
        }
        public RequestWrapper(HttpServletRequest request, String newValue) {
            super(request);
            this.originalValue = request.getRequestURI();
        }
    }
}

但是我所有的测试都失败了。有谁能帮我解决这个问题吗

谢谢

我听不懂你的问题。请解释更多见下面的答案我有一个saas应用程序，它服务于多个客户端。我想给每个客户端一个链接来访问我的应用程序，比如：localhost:8080/client1。如果客户端不存在，我会将其转发到错误页面。我看到这种行为是出于感谢，我在等待你的回应。
