使用继承的Struts2 Convention插件结果 [英] Struts2 Convention Plugin Results Using Inheritance

问题描述

有没有办法让struts2约定插件使用来自超类的结果？

Is there a way to make the struts2 convention plugin use results from a super class?

我正在尝试创建一般CRUD，并使用一般结果子类中没有实现。这可能吗？

I'm trying to create a general CRUD, and use general results if there is no implementation in the child class. Is this possible?

推荐答案

是的，你可以。

例如：

一般CRUD

@Results({
        @Result(name = "input", location = "input.jsp"),
        @Result(location = "input.jsp")
})
public abstract class CrudActionSupport extends ActionSupport {

    @Action("update/{entityId}") // wildcard mapping
    public String actionUpdate() {
        return SUCCESS;
    }
}

操作

public class PersonAction extends CrudActionSupport {

}

---

的注释CrudActionSupport 将始终有效，除非它在子类中被覆盖。

---

The annotation at CrudActionSupport will always in effect, except it is overridden in subclass.

例如

@Results({
        @Result(name = "input", location = "person.jsp"),
        @Result(location = "person.jsp")
})
public class PersonAction extends CrudActionSupport {

    @Override
    public String actionUpdate() {
        return SUCCESS;
    }

    // or 

    /*

    @Action("update/{id}")
    @Override
    public String actionUpdate() {
        return SUCCESS;
    }

    */
}
