struts2中DispatchAction类的替代方法

Question

我从struts1移动到struts2并且我已经在struts2中成功创建了简单的应用程序我想使用Dispatchaction类的未指定/自定义函数，我在struts2中的struts1中使用它，该类将被扩展为执行此操作

Answer 1

No class would be extended; use the "method" attribute in the action configuration , or annotate the method directly if using annotation-based configuration. You can also use wildcard actions to avoid manual configuration.

If that doesn't work for you, please explain specifically what your needs are, and why that won't work.

Answer 2

DispatchAction helps us in grouping a set of related functions into a single action. In Struts 2 all the Actions by default provide this functionality. To use this functionality we need to create different methods with the similar signature of the execute() method, only the name of the method changes.

for eg you can create a Action for User handling which includes method like create,delete update user etc

public class UserAction extends ActionSupport{

    private String methodName;

    public String execute()
    {
        methodName= "Inside execute method";
        return SUCCESS;
    }

    public String add()
    {
        methodName= "Inside add method";
        return SUCCESS;
    }

    public String update()
    {
        methodName= "Inside update method";
        return SUCCESS;
    }
}
