in System Integration scenarios. CAS provides uniform authentication portals for multiple systems, and you only need to log on to multiple systems at a time. LDAP is used to store information commonly used by multiple systems, such as user information and user permission information. This information is common and simple (dominated by strings) with less modification, because they belong to different organizations and systems, they form a tree structure and form a directory. In this way, you can

TESTIn the XML map SQL file, in many cases will use the greater than, less than the special symbols, such as, if you do not control is not compiled through, this time need to use the symbols are described, and the symbols are not parsed, In fact, this problem is not only common in mybatis, but it is common to any XML file used, such as Hibernate, Wabacus, spring, etc. in the configuration file, as long as the XML file is the line, such problems in the future work, often used.

An equal sign is a value assignment. The main problem is the difference between two and three equal signs.The difference between two equal signs and three equal signs in javaScriptIn a word: = convert the type before comparison, = first judge the type, if not the same type, it is directly false.===Indicates constant equals, and the two sides of the comparison must be absolutely the sameAlert (0 = ""); // trueAlert (0 = false); // trueAlert ("" = false

Once discussed with colleagues how to program the elevator control system, the result is that if the structure of the program to write elevators, the system must be very complex and huge. Then I wrote a simple elevator control program with state mode, and the result was greatly simplified. Here is the architecture of a simple single elevator control program that I have written:State mode is a little more complicated, first of all, we analyze an elevat

There are 3 types of Hibernate objects: Transient (Transient), persistent (persistent), and off-state (Detached). Objects that are in persistent state are also known as PO (Persistence object), and instantaneous and de-tube objects are also known as VO (Value object).1.

Java Hibernate objects Thanks to the recent learning of Java Hibernate, there are several states of Java Hibernate Objects sorted, and interested friends can look at it. instantaneous (transient): There is no data in the database that corresponds, and more than the scope is reclaimed by the JVM garbage collector, which is generally new and has no association with the session. Persistent (persistent): data in the database corresponding to the current session with the association, and the asso

The formal approach to data synchronization is to useSQL-ServerBut copying is a little tricky here. From the very beginning, considering the size of the client database and other requirements of the clientMSDEInstall oneSQL-ServerIt is a waste of resources. Considering that the technology of binding to the database platform is not a good choice for the future application of the system. More importantly, in the system, the data synchronization pressure is not very high, and the situation is not

SSO is a single sign-on that controls access to multiple related but independent systems, and users with this privilege can access one or more systems with a single ID and password to avoid using different usernames or passwords, or to log on to each system seamlessly through a configuration.
