Notes for injection in struts2 + spring

During struts2 + spring injection, a non-configuration file problem is found today. There are two methods.

1. Generally, it is better to create a baseaction.
For example

Public class baseaction extends actionsupport

{

 

Proteted usermanaer Mgr;

Public void setusermanager (usermanager MGR)

{

This. Mgr = Mgr;

}

}

Then those strutsactions can do this.
Public Class A extends baseaction

{

 

}

 

2. Implement the struts prepartion Interface

Public class personaction implements preparable {

Public personaction (personservice Service ){
This. Service = service;
}

The preparable interface instructs struts to call the "prepare" method, if "prepareinterceptor" is applied to the action (this is the default ). The action constructor has a "personservice" parameter. Spring is responsible for injection when the action is instantiated.
