Spring Security（二十五）：7. Sample Applications
There are several sample web applications that are available with the project. To avoid an overly large download, only the "tutorial" and "contacts" samples are included in the distribution zip file. The others can be built directly from the source which you can obtain as described in the introduction. It’s easy to build the project yourself and there’s more information on the project web site at http://spring.io/spring-security/. All paths referred to in this chapter are relative to the project source directory.
7.1 Tutorial Sample（教程示例）
The tutorial sample is a nice basic example to get you started. It uses simple namespace configuration throughout. The compiled application is included in the distribution zip file, ready to be deployed into your web container (spring-security-samples-tutorial-3.1.x.war). The form-based authentication mechanism is used in combination with the commonly-used remember-me authentication provider to automatically remember the login using cookies.
web.xml entries) to your existing application. Only when this basic integration is achieved do we suggest you attempt adding in method authorization or domain object security.7.2 Contacts
The Contacts Sample is an advanced example in that it illustrates the more powerful features of domain object access control lists (ACLs) in addition to basic application security. The application provides an interface with which the users are able to administer a simple database of contacts (the domain objects).
webapps directory. The war should be called spring-security-samples-contacts-3.1.x.war (the appended version number will vary depending on what release you are using).Security Debug Information Authentication object is of type: org.springframework.security.authentication.UsernamePasswordAuthenticationToken Authentication object as a String: org.springframework.security.authentication.UsernamePasswordAuthenticationToken@1f127853: Principal: org.springframework.security.core.userdetails.User@b07ed00: Username: rod; \ Password: [PROTECTED]; Enabled: true; AccountNonExpired: true; credentialsNonExpired: true; AccountNonLocked: true; \ Granted Authorities: ROLE_SUPERVISOR, ROLE_USER; \ Password: [PROTECTED]; Authenticated: true; \ Details: org.springframework.security.web.authentication.WebAuthenticationDetails@0: \ RemoteIpAddress: 127.0.0.1; SessionId: 8fkp8t83ohar; \ Granted Authorities: ROLE_SUPERVISOR, ROLE_USER Authentication object holds the following granted authorities: ROLE_SUPERVISOR (getAuthority(): ROLE_SUPERVISOR) ROLE_USER (getAuthority(): ROLE_USER) Success! Your web filters appear to be properly configured!
Once you successfully receive the above message, return to the sample application’s home page and click "Manage". You can then try out the application. Notice that only the contacts available to the currently logged on user are displayed, and only users with ROLE_SUPERVISOR are granted access to delete their contacts. Behind the scenes, the MethodSecurityInterceptor is securing the business objects.
7.3 LDAP Sample
The LDAP sample application provides a basic configuration and sets up both a namespace configuration and an equivalent configuration using traditional beans, both in the same application context file. This means there are actually two identical authentication providers configured in this application.
7.4 OpenID Sample
The OpenID sample demonstrates how to use the namespace to configure OpenID and how to set up attribute exchange configurations for Google, Yahoo and MyOpenID identity providers (you can experiment with adding others if you wish). It uses the JQuery-based openid-selector project to provide a user-friendly login page which allows the user to easily select a provider, rather than typing in the full OpenID identifier.
UserDetailsService which assigns a standard role to any user and stores the identities internally in a map. Obviously a real application would use a database instead. Have a look at the source form more information. This class also takes into account the fact that different attributes may be returned from different providers and builds the name with which it addresses the user accordingly.7.5 CAS Sample
The CAS sample requires that you run both a CAS server and CAS client. It isn’t included in the distribution so you should check out the project code as described in the introduction. You’ll find the relevant files under the sample/cas directory. There’s also a Readme.txt file in there which explains how to run both the server and the client directly from the source tree, complete with SSL support.
7.6 JAAS Sample
The JAAS sample is very simple example of how to use a JAAS LoginModule with Spring Security. The provided LoginModule will successfully authenticate a user if the username equals the password otherwise a LoginException is thrown. The AuthorityGranter used in this example always grants the role ROLE_USER. The sample application also demonstrates how to run as the JAAS Subject returned by the LoginModule by setting jaas-api-provision equal to "true".
7.7 Pre-Authentication Sample
This sample application demonstrates how to wire up beans from the pre-authentication framework to make use of login information from a Java EE container. The user name and roles are those setup by the container.
The code is in samples/preauth.
