authenticationprovider

default implementation of AuthenticationManager is Providermanager, and it does not process the authentication request directly, but instead delegates to its configured Authenticationprovider list. Each authenticationprovider is then used in turn for authentication, and if a authenticationprovider-certified result is not NULL, the

the SecurityContext held by SecurityContextHolder for subsequent programs to call, for example, access permission authentication. AuthenticationManager The main interface used for verification is AuthenticationManager, which has only one method: public interface AuthenticationManager { Authentication authenticate(Authentication authentication) throws AuthenticationException;} There may be three situations after the authenticate () method is run: If the verification succeeds, an Authentication w

the authentication succeeds, it returns a authentication object that encapsulates information such as the current user's permissions. PublicAuthentication Authenticate (authentication authentication)throwsAuthenticationexception {ClassextendsAuthentication> totest =Authentication.getclass (); Authenticationexception lastexception=NULL; Authentication result=NULL; Booleandebug =logger.isdebugenabled ();Using the Authenticationprovider list to proc

When specifying the auto-config= "true" of an HTTP element, it is equivalent to a shorthand for the following. In spring security, the default implementation of AuthenticationManager is Providermanager, and it does not process the authentication request directly, but instead delegates to its configured Authenticationprovider list. Each authenticationprovider is then used in turn for authentication, and if

Java Web series: Spring Security Basics, springsecurity Although Spring Security is much more advanced than JAAS, it is still inherently inadequate and cannot achieve authentication and authorization in ASP. NET. Here we will demonstrate the common functions of logging on, logging off, and remembering me. the user-defined providers for authentication avoid dependency on the database, and the authorized user-defined providers eliminate the negative side effects of role changes caused by loading r

process identity authentication. Instead, it is entrusted to a well-configured authenticationprovider. Each authenticationprovider will take turns checking for identity verification.After checking or returning an authentication object or throwing an exception.Verifying identity is the userdetails of loading the response to see if the user entered the account, password, permissions and other information to

Spring security certification is managed by AuthenticationManager, but the real certification is the Authenticationprovider defined in AuthenticationManager. Multiple authenticationprovider can be defined in AuthenticationManager. When we use the Authentication-provider element to define a authenticationprovider, if the associated

{ Authentication authenticate(Authentication authentication) throws AuthenticationException; } This method can accomplish three things: If it can verify that the input represents a valid principal, it returns one Authentication (usually included authenticated=true ) If it can verify that the input represents an invalid principal, throw aAuthenticationException If it can't decide, it's back.null The most common AuthicationManager imple

In the last spring security post, we used a configuration file to read users from the database and log in. Although the flexibility of this approach is much more flexible than the static account password, it is definitely not a good idea to expose the structure of the database to obvious locations. This article implements the Userdetailsservice interface through Java code to realize the identity authentication.The role of 1.1 Userdetailsservice in identity authenticationThe AuthenticationManager

compile it. It is easy to modify this attribute by configuring the SS applicationcontext. For the SS Authentication Manager, you may have configured it as follows: Security: Authentication-Manager Alias = "Authenticationmanager" > Security: Authentication-provider User-service-ref = "Customuserdetailsservice" > Security: Authentication-provider > Security: Authentication-Manager > An Implementation class of the abstract class just now. org. spring

For this requirement, there are more solutions on the web, such as using filter, custom provider ... My approach is to use a way to increase authenticationprovider. The specific implementation is as follows: 1, add Webauthenticationdetails implementation class, save authentication Code information public class Customwebauthenticationdetails extends Webauthenticationdetails {private Strin G Imagecode; Private String Session_imagecode;

(Authentication authentication)throws AuthenticationException;}Validation logicAuthenticationManagerReceives the Authentication object as the parameter, and authenticate(Authentication) validates it through the method, implements the class to AuthenticationProvider support to the Authentication object validation action, UsernamePasswordAuthenticationToken realizes the Authentication main is the user input user name and the password to encapsulate, and

authentication service provider based on scheme to authenticate the ID, such as Scheme=digest id=qingxu:pwd , which indicates that the Digest keyword corresponds to the certification service provider to authenticate the QINGXU:PWD, ZK provides two providers based on client-side IP (SCHEME=IP) and digest-based (sha1,scheme=digest) user passwords, both of which implement the Authenticationprovider interface, Users can also increase the number of othe

validation logic needs to extend a filter and put it before usernamepasswordauthenticationfilter. SMS Verification code because the phone number is provided, so need to userdetailsservice to determine whether the mobile phone number exists, so need to provide a authenticationprovider call Userdetailsservice to do the verification. The verification of the mobile phone information needs to pass a filter package, the filter should be placed after the us

Preface In the previous article "Spring Security Implementation user name or mobile phone number login", through a custom implementation of the Userdetailsservice interface, the implementation of the support user name + password or mobile phone number + password login problem.In a real-world scenario, it is common for a user to forget the password, except for the forgotten user name. Using mobile verification code to login to the website is becoming more and more popular. Principle Analysis In

user login name, in the user login name query user information, permissions.But in the Internet application, the general user is a privilege. There's no use of the role table, it's not so complicated.3, Custom AuthenticationproviderFirst implement a userdetailsservice. Database queries should be performed here. Then return to Userdetails. Here omit directly create an object, the password is written dead, as long as is the landing successful ride return Role_user permissions.public class myuse

authentication service provider based on scheme to verify and authenticate the ID, for example, scheme = digest id = qingxu: Pwd indicates the certification service provider corresponding to the digest keyword to authenticate qingxu: Pwd, ZK provides two providers: client-based IP address (scheme = IP) and digest-based (sha1, scheme = Digest) User Password. They all implement the authenticationprovider interface, you can also set zookeeper. authpro

Sample Code for adding a verification code to spring security4 and sample code for security4 Spring security is a large module. This article only covers the authentication of custom parameters. The default verification parameters of spring security are username and password, which are generally insufficient. Because it takes too long, I may forget it and may have some omissions. Okay, no nonsense.Java config is used for spring and spring security configurations. The versions are 4.2.5 and 4.0.4

Anonymous authenticationFor anonymous access users, Spring Security supports the creation of an anonymous Anonymousauthenticationtoken store in Securitycontextholder, which is known as Anonymous authentication. In this way, we do not need to judge whether the authentication object held in Securitycontextholder is null in the future for authorization or other operations, and use it directly as a normal authentication. It's OK.ConfigurationWith NameSpace, the use of HTTP elements enables the suppo
