如何覆盖默认的错误消息？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 {
}
}invalid.fieldvalue.age=\u5E74\u9F84\u9519\u8BEF
