如何在一个类中读取全局属性文件? [英] How to read a global property file in a class?

问题描述

我正在阅读以下网址上的struts2教程.

I am reading a struts2 tutorial on the following url.

http://struts.apache.org/2.2. 1/docs/message-resource-files.html

它说明了如何在视图文件中读取属性键的值，但没有说明如何在操作类或模型类中读取属性值.

it explains how to read a value of a property key in a view file, but it doesn't explain how to read property values in an action class or in a model class.

如何读取动作或模型类中的属性键的值?

How do I read a value of a property key in an action or a model class?

推荐答案

使用方法ActionSupport.getText(String).例如:

messages.properties

foo.bar=foobar

struts.xml

<constant name="struts.custom.i18n.resources" value="messages" />

动作类

public class TestAction extends ActionSupport {

    public void method() {

        getText("foo.bar");

    }
}

@Moon:如果我不扩展ActionSupport怎么办?

@Moon : what if I'm not extending ActionSupport?

对于未扩展ActionSupport的类，请使用以下命令(在Struts2运行期间):

For classes not extending ActionSupport, use the following (during run time of Struts2) :

ActionSupport actionSupport = new ActionSupport();
actionSupport.getText("foo.bar");
