tomcat-user.xml增加下面标签(用户名，密码，角色)
<user username="admin" password="new-password" roles="admin"/>

<security-constraint>
    <web-resource-collection>
        <web-resource-name>Restrict access to Solr admin</web-resource-name>
        <url-pattern>/*</url-pattern>
        <http-method>DELETE</http-method>
        <http-method>GET</http-method>
        <http-method>POST</http-method>
        <http-method>PUT</http-method>
    </web-resource-collection>
    <auth-constraint>
        <role-name>admin</role-name>
    </auth-constraint>
    <user-data-constraint>

    </user-data-constraint>
</security-constraint>
<login-config>
