Spring security automatically calculates the results to match the information stored in the database to determine whether the user can log in.In this way, we have added a single line of configuration, which brings the function of password encryption to the system.2. Salt-Value encryptionThe above example in the real use of the existence of a very small problem. Although the MD5 algorithm is irreversible, b

Org.springframework.security.core.Authentication Interface instance. 2. After getting the authentication object, the filter invokes the Authenticate method of the Providermanager class and passes in the object The Authenticate method of the 3.ProviderManager class then calls its own Doauthentication method, which in the Doauthentication method invokes the list 4.AuthenticationProvider interface to obtain user information via Userdetailsservice The following is a timing diagram: Article 2: Wor

Here we are only focusing on daoauthenticationprovideR (the provider who obtains user authentication information from the database), I have limited level, have not had the opportunity to use other providers in the project. In this case, where is the userdetails that encapsulates the user's details? This is the Userdetailsservice interface that we are going to introduce, which only defines the unique Userdetailsloaduserbyusername (String username) method, It uses the use

In general, the security of a WEB application includes two parts of user authentication (authentication) and user authorization (Authorization). User authentication refers to verifying that a user is a legitimate principal in the system, which means that the user can access the system. User authorization refers to verifying that a user has permission to perform an action. In a system, different users have different permissions. For example, for a file

session.Alternatively, specifying a custom AccessDeniedHandler allows you-to-process the any InvalidCsrfTokenException -you-like. For a example the Customize the refer to the AccessDeniedHandler provided links for both XML and Java configuration.Finally, the application can is configured to use cookiecsrftokenrepository which would not expire. As previously mentioned, this is not as secure as with using a session, but the many cases can be good enough.https://docs.spring.io/

SPRINGMVC's controller is singleton (non-thread safe), which is probably the difference between him and struts2.Original Address: thread security issues with spring concurrent access Like struts, Spring's controller defaults to Singleton, which means that every request comes in and the system is processed with the original instance, which results in two outcomes: one is that we don't have to create a contr

If so, take the securitycontext out and put it in the Securitycontextholder for use by other parts of spring security. If it does not exist, create a securitycontext, or put it in Secu

the Md5/sha algorithm have a very big difference, each generated hash value is different, so the violent guess may be more difficult to solve. At the same time, you may also find that the length of the encrypted character is longer, there are 60 bits, so the length of the password field in the user table, if you intend to use bcrypt encrypted storage, the field length must not be less than 60.Second, Spring-security.xml"http://www.springframework.org
