给定一个 Servlet HelloServlet:
@WebServlet("/HelloServlet")
public class HelloServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* Default constructor.
*/
public HelloServlet() {
// TODO Auto-generated constructor stub
}
@Override
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
System.out.print("hello my Friend: " + request.getRemoteUser());
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("This is the Test Servlet");
Enumeration headerNames = request.getHeaderNames();
while (headerNames.hasMoreElements()) {
String headerName = (String) headerNames.nextElement();
out.print("<br/>Header Name: <em>" + headerName);
String headerValue = request.getHeader(headerName);
out.print("</em>, Header Value: <em>" + headerValue);
out.println("</em>");
}
}
....
}
在 web.xml 中声明了 tomcat 安全策略:
<security-constraint>
<web-resource-collection>
<web-resource-name>my application</web-resource-name>
<url-pattern>/*</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
<auth-constraint>
<role-name>tomcat</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>FORM</auth-method>
<form-login-config>
<form-login-page>/login.jsp</form-login-page>
<form-error-page>/login-failed.jsp</form-error-page>
</form-login-config>
</login-config>
和 conf/tomcat-users.xml 中的 tomcat-roles 定义
<role rolename="tomcat"/>
<role rolename="role1"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
<user username="role1" password="tomcat" roles="role1"/>
“server.xml”中的领域是:
<Realm className="org.apache.catalina.realm.LockOutRealm">
<!-- This Realm uses the UserDatabase configured in the global JNDI
resources under the key "UserDatabase". Any edits
that are performed against this UserDatabase are immediately
available for use by the Realm. -->
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="UserDatabase"/>
</Realm>
,我尝试使用 url localhost/jsfWorkgroup/HelloServlet 访问 Servlet“HelloServlet”。
像预期的那样,我被(重新)定向到登录页面:
<form method="POST" action="j_security_check">
<table>
<tr>
<td colspan="2">Login to the Tomcat-Demo application:</td>
</tr>
<tr>
<td>Name:</td>
<td><input type="text" name="j_username" /></td>
</tr>
<tr>
<td>Password:</td>
<td><input type="password" name="j_password"/ ></td>
</tr>
<tr>
<td colspan="2"><input type="submit" value="Go" /></td>
</tr>
</table>
</form>
无论我使用哪个 id-Token:
- 用户名:tomcat 密码:tomcat
- 用户名:两个密码:tomcat
我还是来了失败/login-failed.jsp。
这是我对此的看法:tomcat 将我重定向到登录页面,但不会读取 conf/tomcat-users.xml 来验证我的登录(即使在多次重新启动后)。
你怎么看待这件事 ?
配置:Tomcat 7.0.23,Eclipse-Indigo
