We know that the integration of STRUTS1 and spring is achieved by Org.springframework.web.struts.DelegatingActionProxy, the following is a specific user login implementation to illustrate the STRUTS2 integration of spring related content .First, the preparatory work1.

Expectednumberofrenewspermin is refreshed every 15 minutes by default.From the above analysis, we have a general understanding of the conditions that trigger the service culling operation without shutting down the self-protection mode. The following two kinds of schemes are obtained to eliminate the failure nodes (pro-test is effective). By modifying the minimum rate of heartbeat success per minute to control that the registry does not enter self-protection mode, the node is rejected

Transaction management under Spring-using AOP XML configuration management (IBatis as an example) There are three ways to manage things under Spring: programmatic transaction management, declarative transaction management, and AOP transaction management. AOP transaction management is divided into AOP annotation transaction management and AOP XML configuration, wh

Check that the configuration file has not joined the transaction management configuration and driver;2. Check whether the database supports transactions (such as MySql4.0 support transactions, ENGINE:INNODB);3. Checks whether the code block throws an exception, and the rollback exception of the transaction is the parent class that throws an exception or throws an exception;4. Check that all conn

Example of using bootstrap-table to implement server paging (spring background ), Recently, the bootstrap table plug-in is used on the front end. If the client page contains a large amount of data, it is difficult to interact with each other. Therefore, pages with large data volumes are used on the server side. The following starts the commit code: Front end First, let's take a look at the default paging pa
