Struts2框架的输入校验（一）

在项目中，算是为了学习吧，我采用了两种方式，本文并未进行类型转换的异常处理，在实际应用过程中，程序的流程是：Struts2对客户端传来的数据进行类型转换->输入校验->execute方法(方法名称不一定为execute，准确的讲应为action对应的的方法名称)。

现分别将两种校验方式进行如下记录描述（注：错误提交都采用addFieldError方式）：

 

一、自定义校验方法

校验的方法名称为validate + action方法名称（大写第一个字母），如下文中的validateAdd 与add，在jsp页面要加入<s:fielderror></s:fielderror> 来处理输入校验时加入addFieldError的信息。

下面是对应的文件：PowerArea.java(台区信息类) 、PowerAreaAct.java(台区信息action类)、powerarea_add.jsp(显示页面)、document.xml(xml配置文件)、struts.xml(框架配置文件)、MySuperAction.java(接口类)。

 

各文件关键代码如下：

1、PowerArea.java

 package com.techen.masterstation.document;/** * 台区信息类 * */public class PowerArea {private String lineId;private String id;private String name;private String measureKind;private String industry;private String inVoltage;private String outVoltage;private String capacity;private String address;private String linkman;private String tel;public String getLineId() {return lineId;}public void setLineId(String lineId) {this.lineId = lineId;}public String getId() {return id;}public void setId(String id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getMeasureKind() {return measureKind;}public void setMeasureKind(String measureKind) {this.measureKind = measureKind;}public String getIndustry() {return industry;}public void setIndustry(String industry) {this.industry = industry;}public String getInVoltage() {return inVoltage;}public void setInVoltage(String inVoltage) {this.inVoltage = inVoltage;}public String getOutVoltage() {return outVoltage;}public void setOutVoltage(String outVoltage) {this.outVoltage = outVoltage;}public String getCapacity() {return capacity;}public void setCapacity(String capacity) {this.capacity = capacity;}public String getAddress() {return address;}public void setAddress(String address) {this.address = address;}public String getLinkman() {return linkman;}public void setLinkman(String linkman) {this.linkman = linkman;}public String getTel() {return tel;}public void setTel(String tel) {this.tel = tel;}}

2、PowerAreaAct.java
