Struts 2 如何在Action類別中取得ServletContext

在Struts 2的Action類可使用下面方法取得ServletContext

在Action中可直接呼叫ServletActionContext.getServletContext()來取得ServletContext物件。

import javax.servlet.ServletContext;
import org.apache.struts2.ServletActionContext;
import com.opensymphony.xwork2.ActionSupport;

public class DemoAction extends ActionSupport{

  public String execute() throws Exception {

    ServletContext context = ServletActionContext.getServletContext(); // 取得ServletContext

    return SUCCESS;

  }

}
