------解决方案--------------------
在你的tomcat/conf/Catalina/localhost/${webapp}.xml里面 <Context> 标签中加上
<ResourceLink name= "users " global= "UserDatabase "
type= "org.apache.catalina.UserDatabase "/>

在你的webapp/WEB-INF/web.xml里面加上

<!-- Define reference to the user database for looking up roles -->
<resource-env-ref>
<description>
Link to the UserDatabase instance from which we request lists of
defined role names. Typically, this will be connected to the global
user database with a ResourceLink element in server.xml or the context
configuration file for the Manager web application.
</description>
<resource-env-ref-name> users </resource-env-ref-name>
<resource-env-ref-type>
org.apache.catalina.UserDatabase
</resource-env-ref-type>
</resource-env-ref>

<!-- Define a Security Constraint on this Application -->
<security-constraint>
<web-resource-collection>
<web-resource-name> Authorization </web-resource-name>
<url-pattern> /* </url-pattern>
</web-resource-collection>
<auth-constraint>
<!-- NOTE: This role is not present in the default users file -->
<role-name> authRole </role-name>
</auth-constraint>
</security-constraint>

<!-- Define the Login Configuration for this Application -->
<login-config>
<auth-method> BASIC </auth-method>
<realm-name> Authorization Application </realm-name>
</login-config>

<!-- Security roles referenced by this web application -->
<security-role>
<description>
The role that is required to log in to the Authorization Application
</description>
<role-name> authRole </role-name>
</security-role>

然后在你的tomcat/conf/tomcat-user.xml里面增加用户abc（密码123），所属的role是authRole
<user name= "abc " password= "123 " roles= "authRole " />


------解决方案--------------------
可以参考tomcat中的manager这个webapp的配置
tomcat/conf/Catalina/manager.xml
tomcat/server/webapps/manager/WEB-INF/web.xml
