struts2 中，怎么覆盖默认的异常消息

struts2 中，如何覆盖默认的错误消息
如何覆盖默认的错误消息？
①：在对应的Action 类所在的包中新建 ActionClassName.preperties 文件,ActionClassName即为包含着字段的Action 类的类名

②：在属性文件中添加如下键值对：invalid.fieldvalue.fieldName=xxx

1.项目结构

2.示例如下：

Ⅰ类

① 实体类

package com.baidu.domain;

public class Person {
	private int age;

	public Person() {
		super();
	}
	public Person(int age) {
		super();
		this.age = age;
	}
	
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	@Override
	public String toString() {
		return "Person [age=" + age + "]";
	}
	
}

② Action：ConversionAction.java

package com.baidu.conversion;

import com.baidu.domain.Person;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import com.opensymphony.xwork2.Preparable;

public class ConversionAction extends ActionSupport implements   ModelDriven<Person>,Preparable {

	private static final long serialVersionUID = 1L;
	
	public String testAge(){
		System.out.println(person);
		return "success";
	}
	
	private Person person;
	@Override
	public Person getModel() {
		person = new Person();
		return person;
	}
	@Override
	public void prepare() throws Exception {

	}

}

③ 错误消息的配置文件：ConversionAction.properties 其和Action在同一包下

invalid.fieldvalue.age=\u5E74\u9F84\u9519\u8BEF

Ⅱ 配置文件
① struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
	"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
	"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

				</interceptor-ref>
			</interceptor-stack>		
		</interceptors>
		<default-interceptor-ref name="baiduStack"/>
		
		<action name="testConversion" class="com.baidu.conversion.ConversionAction"
			method="testAge">
			<result name="success">/index.jsp</result>
			<result name="input">/index.jsp</result>
		</action>

	</package>

</struts>

② web.xml

<?xml version="1.0" encoding="UTF-8"?>

  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>

struts2 中，怎么覆盖默认的异常消息

1楼chuck_kui2小时前: 若 Action 类实现 ValidationAware 接口：n Struts 在遇到类型转换错误时将不会继续调用其 Action 方法: n Struts 将检查相关 action 元素的声明是否包含着一个 name=input 的 result. n 如果有, Struts 将把控制权转交给那个 result 元素; 若没有 input 结果, Struts 将抛出一个异常n 详见上面Ⅱ 配置文件中：struts.xml 的配置文件
