動態呼叫：

注意：要把struts.enable.DynamicMethodInvocation的值為true，如

<constant name="struts.enable.DynamicMethodInvocation" value="true" />，否則無法動態訪問

Action.java

import com.opensymphony.xwork2.ActionSupport;

public class TestActionDynamic extends ActionSupport{
	
	@Override
	public String execute() throws Exception {
		System.out.println("TestActionDynamic execute...");
		return super.execute();
	}
	
	public String add(){
		System.out.println("TestActionDynamic add...");
		return SUCCESS;
	}
	
	public String del(){
		System.out.println("TestActionDynamic del...");
		return SUCCESS;
	}
	
	public String updata(){
		System.out.println("TestActionDynamic updata...");
		return SUCCESS;
	}
}

</struts>
 

預設Action：
在<package>下配置<default-action-ref name="Actio名"></default-action-ref>，如果在瀏覽器中輸入的Actio名無效，即自動訪問預設的Actio

注意：在struts2.3.4以下如果設了預設Action，再進行動態呼叫Action，會出現錯誤，在struts2.3.4以上就不會發生錯誤。
