一、需求
solr安装完成以后，只要知道url就可以访问到solr后台,显然这很不安全，那么需求就是在访问的时候需要输入密码验证。
二、配置
1、修改部署solr的Tomcat的tomcat-users.xml
<!-- NOTE: The sample user and role entries below are intended for use with the examples web application. They are wrapped in a comment and thus are ignored when reading this file. If you wish to configure these users for use with the examples web application, do not forget to remove the <!.. ..> that surrounds them. You will also need to set the passwords to something appropriate. --> <!-- <role rolename="tomcat"/> <role rolename="role1"/> <user username="tomcat" password="<must-be-changed>" roles="tomcat"/> <user username="both" password="<must-be-changed>" roles="tomcat,role1"/> <user username="role1" password="<must-be-changed>" roles="role1"/> --> <!--添加用户名和密码--> <role rolename="solr"/> <user username="admin" password="admin" roles="solr"/> </tomcat-users>
2、修改 WEB-INF/web.xml 在<webapp>节点内增加如下内容
<security-constraint> <web-resource-collection> <web-resource-name>Solr Lockdown</web-resource-name> <url-pattern>/</url-pattern> <http-method>GET</http-method> <http-method>POST</http-method> </web-resource-collection> <auth-constraint> <description>This applies only to the "tomcat" security role</description> <role-name>solr</role-name> <role-name>admin</role-name> </auth-constraint> <user-data-constraint> <transport-guarantee>NONE</transport-guarantee> </user-data-constraint> </security-constraint> <login-config> <auth-method>BASIC</auth-method> <realm-name>Solr</realm-name> </login-config>
3、重启Tomcat ，访问就会要求输入用户名密码,输入上面设置的账号密码然后就可以登录。但是还有一个问题，页面加上密码，程序代码中就访问不到了，报HTTP/1.1 401 Unauthorized这个错误。下面解决这个问题只需要你修改一下链接即可
@Test public void testQuery() throws SolrServerException{//过滤查询 //修改此处链接 //SolrServer solrServer=new HttpSolrServer("http://192.168.220.121:8080/solr/mycore"); SolrServer solrServer=new HttpSolrServer("http://admin:admin@192.168.139.129:8080/solr/mycore"); SolrQuery query=new SolrQuery(); query.set("q", "*:*"); String [] fq={"item_cat_id:2"}; query.addFilterQuery(fq); //过滤 QueryResponse result = solrServer.query(query); SolrDocumentList results = result.getResults(); for (SolrDocument list:results){ String str1 = list.get("item_gid").toString(); String str2=list.get("item_title").toString(); System.out.println("分类gid-----"+str1); System.out.println("商品名称-----"+str2); } }
