怎么用web过滤器增加solr后台登录验证

这篇文章主要讲解了"怎么用web过滤器增加solr后台登录验证"，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习"怎么用web过滤器增加solr后台登录验证"吧！

solr后台自带是没有登录功能的，默认访问地址是：http://localhost:8983/solr/#/(内置jetty运行)。
要给sorl后台增加登录验证方法：
1、使用web服务器的登录验证(例如jetty、tomcat)
这种方式好处是不需要另外写代码，只需配置一下对应的web服务器就行了。
2、使用web过滤器过滤地址验证
这种方法是更加灵活，缺点是需要点代码开发。

本文介绍的是第二种方法：

SolrLoginFilter.javapackage com.penngo.solr;import java.io.IOException;import java.io.PrintWriter;import javax.servlet.Filter;import javax.servlet.FilterChain;import javax.servlet.FilterConfig;import javax.servlet.ServletException;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import javax.servlet.http.HttpSession;import org.apache.commons.lang3.StringUtils;public class SolrLoginFilter implements Filter {  public void init(FilterConfig config) throws ServletException {  }  public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)      throws IOException, ServletException {    HttpServletRequest httpRequest = (HttpServletRequest)request;    HttpServletResponse  httpResponse = (HttpServletResponse)response;    HttpSession session = httpRequest.getSession();    String url = httpRequest.getRequestURL().toString();    String userAgent = httpRequest.getHeader("user-agent");    String query = httpRequest.getQueryString();    String servletPath = httpRequest.getServletPath();    String contextPath = httpRequest.getContextPath();    System.out.println("url======="        + ", url:" + url + ", servletPath:" + servletPath + ", contextPath:" + contextPath + ", query:" + query         + ", userAgent:" + userAgent);    Object isLogin = session.getAttribute("isLogin");    if(isLogin == null || ((boolean)isLogin) != true) {      String user = StringUtils.isEmpty(request.getParameter("user")) == false ? request.getParameter("user") : "";      String password = StringUtils.isEmpty(request.getParameter("password")) == false ? request.getParameter("password") : "";      if(user.equals("admin") == true && password.equals("123") == true) {        session.setAttribute("isLogin", true);        httpResponse.sendRedirect(contextPath);        return;      }      else {        httpRequest.setCharacterEncoding("UTF-8");        response.setContentType("text/html;charset=UTF-8");        PrintWriter out = response.getWriter();        out.println(loginPage());        out.close();        return;      }    }    chain.doFilter(request, response);  }  public void destroy() {  }  private String loginPage() {    String page = "\n"        + "\n"         + "\n"        + "
\n"        + "用户名：

\n"        + "密  码：

\n"        + "登录 \n"        + "
\n"        + "";    return page;  }}

在原来的web.xml中增加过滤器配置

                    SolrLoginFilter        com.penngo.solr.SolrLoginFilter                SolrLoginFilter        /                                SolrRequestFilter        org.apache.solr.servlet.SolrDispatchFilter                            excludePatterns            /partials/.+,/libs/.+,/css/.+,/js/.+,/img/.+,/templates/.+                        SolrRequestFilter        /*                LoadAdminUI        org.apache.solr.servlet.LoadAdminUiServlet                SolrRestApi        org.restlet.ext.servlet.ServerServlet                    org.restlet.application            org.apache.solr.rest.SolrSchemaRestApi                        LoadAdminUI        /index.html                SolrRestApi        /schema/*                .xsl                application/xslt+xml                index.html                                Disable TRACE            /            TRACE                                            Enable everything but TRACE            /            TRACE            

运行结果：
