in order to understand, I translated the overview section of the Accountmanager class. Reprint Please specify source: http://www.cnblogs.com/vir56k/p/4025722.htmlAccountmanager OverviewThis class provides the ability to access a centralized registry of users ' online accounts. The user enters authentication information for each account (credentials, which contains the user name and password), and clicks once (one-click) to complete the authentication, authorizing the application (app) to access

filter to prevent users from accessing some unauthorized resources. The filter intercepts all requests/response, Then put a token that passes the verification in the user's session, and then the filter determines whether to allow response each time based on the token. This mode is divided: Keeper: filters or unified servlet. Authenticator: Use JAAS to implement it on the web. User qualification storage LDAP or database: 1. The Keeper intercepts and c

The following describes the Shiro authentication internal processing mechanism in detail.For example, we use the Shiro architecture diagram to explain the internal processing sequence of Shiro certification:1.

-control request command:End-to-end ReloadThe request contains a "No-cache" cache control directive, or "pragma:no-cache" for compatibility with the http/1.0 client. The No-cache directive in the request cannot contain field-name. When responding to such a request, the server cannot use the cached copy.Specific End-to-end revalidationThe request contains a "max-age=0" cache control directive, which forces each cache along the source server path, if any, to re-verify its own entries.

. When I was studying JavaEE, I had access to the javaMail mail sending function. At that time, I had a very simple understanding of the Email protocol, after reading the email protocol of the computer network, I went back to review the related content of JavaMail. Here is a summary:Jar package to be imported using javaMail: 1. mail. jar 2. activation. jar javaMail core class: Session: This session is not another session. Here is a class in javaMail. The Session class defines the basic mail Sess

The field changes with the attribute field and receives valid response packets, but remains unchanged during re-transmission. The Authenticator domain (16 bytes) is used to verify the request sent back from the RADIUS server and to hide the password. Algorithm Request authenticator and resp

I saw the email development video explained by Zhang Xiaoxiang, but I only watched a small part of it. At that time, I was a little newbie and didn't understand it. I thought it was a very complicated technology. The mail sending function is used in a small project that has recently been practiced. This function is implemented by referring to the Code on the Internet. Now, it's so easy! Before enabling this function, you need to download the jar package mail. Jar required for sending emails.

Used to think that JavaMail is a very tall thing, so on the Internet to find the knowledge about JavaMail, in fact, did not think so tall, I just learned to send the mail part, then I would like to paste the code I wrote, specific implementation code has a detailed explanationThe first is to send a regular message//Send regular mail Public Static voidSendtextmail ()throwsmessagingexception {//first step.
