QuestionsIn a Web project, there are typically two components:1) static resources, such as HTML pages, JS scripts, pictures and so on.2) API interface.These two parts need to be managed uniformly in the case of permission control.The spring framework itself provides a powerful

Spring Security also provides a note-based approach to implementing method-based Authorization. This is the @RolesAllowed note presented in this article . @RolesAllowed are annotations defined by JSR250. (1) in the Spring-security.xml files are enabled JSR250 annotation Support. -jsr250-annotations= "enabled"/ >(2) in the method that requires authorization con

Session Fixation attack uses the server's session unchanged mechanism to authenticate and authorize others and impersonate others. If the applicationProgramWhen a user creates an anonymous session for each user upon the first access to it, a session fix vulnerability often occurs. Then, once the user logs on, the session is upgraded to a verified session. Initially, the session token is not granted any access permission, but after the user passes the authentication, the token also has the access

Spring Security provides @Secured Annotations to implement method-based authorization control. @Secured Annotations You can specify a string array parameter as A value that indicates that the current user has any one of these roles to satisfy the authorization criteria. (1) enabled @Secured annotations. secured-annotations= "Enabled" />(2) Use Secured annotations. //the Getuserbyname () method can be ac

1.1.Hierarchical role SystemUse Spring Security 's hierarchical role architecture simplifies the configuration of complex roles. The configuration process is as follows:(1) First, you need to http The Access Decision manager is specified in the node. the correspondence between roles and URL patterns Access-decision-manager-ref: Specifies the Access decision manager to use. - sec:httpAuto-config= "true"use-

Now the development of the document translation, because it is difficult to read English. first Look at the official guide. Developers Guide , all two versions of OAuth are available.

The specific cause of this problem is generally the following two points: 1. In the authorized section we generally authorize by using our own login action HTTP BASIC, while we use spring security only exposed the login interface, which means that the other interfaces are in spring Security protection, including the/oa

Tags: spring security databaseOberzhang review:in the previous chapter, we configured the user name, password, and user-corresponding roles in Applicationcontext-security.xml , which basically implemented the ability to control the user's access rights. But in real-world development, we can not hard code user information in the configuration file, usually we are stored in the data. At the same time we shoul

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

Read the Official document first: http://docs.spring.io/spring-security/site/docs/4.0.x/reference/htmlsingle/ Spring Security4 has added a way to annotate, but in order to get a clearer picture, the configuration is used.

We used to use the MD5 before.Md5PasswordEncoderor ShaShaPasswordEncoderhash algorithm for password encryption, which is still used in spring security as long as the custom encryption algorithm is specified, it is now recommended that the bcrypt used by springBCryptPasswordEncoder, a strong hash encryption algorithm based on a randomly generated salt. First we encrypt password 123456 using the encryption me
