如果想对action中的指定方法进行输入校验，只需要validateXxx()就行了。
package com.isoftstone.study;
import java.util.regex.Pattern;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
public class PersonAction extends ActionSupport{
private String username;
private String mobile;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getMobile() {
return mobile;
}
public void setMobile(String mobile) {
this.mobile = mobile;
}
public String update(){
ActionContext.getContext().put("message", "更新成功");
return "message";
}
public String save(){
ActionContext.getContext().put("message", "保存成功");
return "message";
}
// @Override
// public void validate(){//会对该action中的所有方法进行校验
// if(this.username==null||"".equals(username.trim())){
// this.addFieldError("username", "用户名不能为空");
// }
// if(this.mobile==null||"".equals(mobile.trim())){
// this.addFieldError("mobile", "手机号不能为空");
// }else{
// if(!Pattern.compile("^1[358]\\d{9}$").matcher(this.mobile).matches()){
// this.addFieldError("mobile", "手机格式不正确");
// }
// }
// }
// @Override
public void validateUpdate(){//会对该action中的所有方法进行校验
if(this.username==null||"".equals(username.trim())){
this.addFieldError("username", "用户名不能为空");
}
if(this.mobile==null||"".equals(mobile.trim())){
this.addFieldError("mobile", "手机号不能为空");
}else{
if(!Pattern.compile("^1[358]\\d{9}$").matcher(this.mobile).matches()){
this.addFieldError("mobile", "手机格式不正确");
}
}
}
如果校验真的是没有问题的，那么还是总是跳到input视图，那么就是类型转换器的问题。
