The struts2.5 framework uses wildcards to specify methods (Common Errors), and struts2.5 wildcards
When learning the struts framework, you will often use the wildcard call method as follows:
In the action name = "user _ *", * the value represented by this symbol is passed into method = "{1}" and corresponds to a method name of the action class, this greatly reduces the number of actions in the configuration document.
However, when using this wildca

The coupling of views to the caching system is not ideal in several ways. For example, you might want to reuse the view function in a site that is not cached, or you might want to publish the view to someone who doesn't want to use it through the cache. The way to solve these problems is to specify the view cache in URLconf instead of the view function itself.
It's very simple to do this: simply wrap a cache_page when using these view functions in U
Example one:
Copy the Code code as follows:
#!/usr/bin/pythonImport SysImport reIf __name__== "__main__":F=file ("Hi.txt", "w+")li=["hello\n", "hi\n"]F.writelines (LI)F.close ()
"w+" mode: Creates a file write if there is no hi.txt and, if present, empties the Hi.txt content and writes from the new.

Because the running program is protected by Windows, even if the virus is detected, it is often killed and cannot be deleted. What if anti-virus software kills the virus? In the past, it was generally recommended to kill in security mode or DOS mode. There is now a new method called "specify the debugger in the Image File Execution options". This method should be feasible. The principle is to modify the registry so that the virus cannot be started the

In mysqld section of my. cnf, add bind-address = 127.0.0.1. MySQL can only listen to a specific address.
Q: How can I specify that MySQL only listens to a specific address?
A: A common method is to add bind-address = 127.0.0.1 in mysqld section of my. cnf. However, some people follow these steps.
For data security, you can consider allowing MySQL to only wait on 127.0.0.1, So that you cannot directly access the database from the Internet. Modify th
there is a class import conflict. Assuming that there are three top-level paths at this point, the compiler will perform a 3*5=15 lookup.Note: If the compiler discovers two classes with the same name after the lookup is complete, an error will be made. To delete the class that you don't use, and then compile it.Knowing the above, we can conclude that the on-demand type import will never degrade the execution efficiency of Java code, but it will affect the compilation speed of Java code.View the
