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.

Bean configuration example in Spring: Below is a complete Bean configuration example:

the creation of a different cake object, or the next get cake will appear two of the same ID cake, this is obviously not in line with the actual situation.(5) But the oven is not the same, because for the bakery, the number of ovens is certain, can not appear multiple ovens, so they must use the default singleton mode(6) When you configure the oven properties in the chef, we use set, so that even if the configuration is more than the above, it will not be repeated, because this collection has t

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

ready.SummarySteps to resolve if you encounter a SPRINGMVC transaction that cannot be rolled back:1. 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

Web In web development, user access to the Web page is an important part of the inspection. In the case of strust, we need to write the relevant code in the action's Excute method (usually the function that calls the base class), and it is clear that this is a repetitive labor in each action. This is a good solution if we can automatically invoke the permission check function of the base class before we run the Excute. AOP provides us with such a workaround.The following is a simplified

Having studied the new Spring 2.5 for a long time, I finally figured out how to define the bean with annotations, but how to define and inject the bean with type java.lang.String still unresolved, hoping to get expert help. Overall the Java EE 5 annotation Development Way is to be recognized by everyone. @Service is equivalent to defining a bean, which automatically generates a lowercase first-letter bean based on the Bean's class name @Autowired i

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
