Spring MVC defaults to a single case mode, Controller, Service, DAO are single cases so there are some security risks in the improper use. The benefits of the controller single example pattern are:1. Improve performance without creating controller instances at a time, reducing the time for object creation and garbage collection2. No more cases of necessityBecause there is only one controller instance, when

To implement the Logout feature we need to define the logout element under the HTTP element, so spring security will automatically add a filter logoutfilter to Filterchain for us to handle the exit login. When we specify that the HTTP element's Auto-config property is true, the logout definition is automatically configured, at which point we exit the login by default with the URL "/j_spring_security_logout"

The Spring boot security csrf was used in a project, Part of the project is the API, called through the URL, and requires the use of a POST request So the trouble comes, using CSRF, call API request is rejected, because there is no CSRF, think the session expired How do we get around? public class Securityconfig extends websecurityconfigureradapter{ protected void Configure (Httpsecurity http) throws E

Spring Security provides 4 annotations for a method:@PreAuthorize,@PostAuthorize,@PreFilter , and @PostFilter. This article describes the previous 2 annotations. @PreAuthorizeUse Spring Security expressions are used to control the execution of a method before the method executes.

Recently learning the Spring security framework, learning to use the security framework to complete the system's secure channel control, to go back and forth encountered a lot of problems. Spring tutorial on the slightly simple, for me, such as small white is not enough to support the reading code, fortunately there is

The Entry-point-ref property , in English, means an entry point reference. Why do you need this entry point? This entry point is actually simply quoted by Exceptiontranslationfilter. The Exceptiontranslationfilter filter has been introduced in the previous role is abnormal translation, in the event of authentication anomalies, access anomalies, through the entry point to determine the operation of redirect, forward.
