Spring security is a secure framework that provides declarative, secure access control solutions for spring-based enterprise applications. It provides a set of beans that can be configured in the context of the spring application, taking full advantage of the spring Ioc,di (control inversion inversion of controls, di:d

Sometimes you need to control access based on IP addresses to restrict or guide certain access requests. For example, allow normal access from visitors in the LAN segment, but prohibit access from the Internet. Mango briefly intro

CBAC is a context-based access control protocol. It checks the traffic of the firewall to find the session status information for managing TCP and UDP. These status information is used to create a temporary channel in the firewall access list. Configure the ipinspect list in one direction to allow the returned traffic.

RuntimeException, with its getsql () or GetMessage () method to know the SQL statement that raised the timeout. When a timeout is blocked using the JDBC Driver socket, the current connection is closed by Driver, and the operation being performed in the transaction, whether through JdbcTemplate or another ORM framework, is raised SqlException ( Exception information is: Closed connection), this exception will be captured by the upper Transactioninterceptor and repackaged as an instance of uncate

RBAC Reference Model: Core RBAC Hierarchical RBAC Static separation of duty relations Dynamic separation of duty relations Advantages of RBAC:Authorization management is convenient. If the system administrator needs to modify system settings and other content, there must be several users with different roles present for the operation to ensure security.The roles of financial personnel can be distinguished based on work requirements.
