FilterDispatcher has been marked as obsolete solutions >>> FilterDispatcher

Some Struts 2 tutorial is relatively early , when we are on a newer version of struts2 time to implement the code , often there will be some problems . For example, this warning: FilterDispatcher isdeprecated!

In web.xml configuration as follows :

<filter>  
    <filter-name>struts2</filter-name>  
    <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>  
</filter>  

But there will be a run up, as shown in the warning: FilterDispatcher outdated it! Please use the new filter!

Open link warning mentioned, we can find FilterDispatcher Example (web.xml)

This FilterDispatcher Example did not FilterDispatcher, but became this sentence:

org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

Look down from the original> = 2.1.3 version of the beginning, FilterDispatcher is marked as obsolete, replaced by a new

StrutsPrepareAndExecuteFilter

So if your struts version greater than 2.1.3 When, filter configured to become:

org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter。

If it is lower than version 2.1.3, you can also use the beginning of this article can be configured.
