为solr增加用户验证

添加此功能主要是为了增加solr服务器的安全性，不能随便让人访问。

1.      在tomcat的F:Tomcat 6.0.26_solrconf omcat-users.xml添加用户角色并指定访问的用户名密码

1. <role rolename="solr"/>
2. <user username="admin" password="admin" roles="solr"/>

2. 在F:Tomcat6.0.26_solrwebappssolrWEB-INFweb.xm中添加用户访问权限设置

1. <security-constraint>
2. <web-resource-collection>
3. <web-resource-name>Solr Lockdown</web-resource-name>
4. <url-pattern>/</url-pattern>
5. <http-method>GET</http-method>
6. <http-method>POST</http-method>
7. </web-resource-collection>
8. <auth-constraint>
9. <description>This applies only to the "tomcat" security role</description>
10. <role-name>solr</role-name>
11. <role-name>admin</role-name>
12. </auth-constraint>
13. <user-data-constraint>
14. <transport-guarantee>NONE</transport-guarantee>
15. </user-data-constraint>
16. </security-constraint>
17.  
18. <login-config>
19. <auth-method>BASIC</auth-method>
20. <realm-name>Solr</realm-name>
21. </login-config>

如果弹出此框并且能正常登录，说明已经配置成功
