胸椎第一节:一个实用的去除前后空格的小工具
来源:百度文库 编辑:偶看新闻 时间:2024/05/06 05:41:35
企业开发中往往有这样的需求,用户界面输入的东西都要去除前后空格。
之前的做法是,取出formbean里的每一个属性依次验证。想想,费时又费用,抽时间我写了一个通用工具类,一句代码就能搞定。
用法如下:
FormBean:
public class FormBean {
private int age;
private String name;
private Date birth;
private String[] fav;
private int score[];
public int[] getScore() {
return score;
}
public void setScore(int[] score) {
this.score = score;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public Date getBirth() {
return birth;
}
public void setBirth(Date birth) {
this.birth = birth;
}
public String[] getFav() {
return fav;
}
public void setFav(String[] fav) {
this.fav = fav;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
测试:
FormBean f = new FormBean();
f.setAge(232);
f.setBirth(new Date());
f.setName(" ddd ");
f.setFav(new String[]{" aa "," bb "});
f.setScore(new int[2]);
FormBeanUtil.stripStringProperty(f); //去前后空格
