通过注解的方式，可以让方法不用验证
@SkipValidation
public String toRegView() {
System.out.println("toRegView");
return "regView";
}
public class ValidateAction extends ActionSupport {
private static final long serialVersionUID = -6933309304624396640L;
private String name;
private Integer age;
private String password ;
private String confirmPassword ;
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getConfirmPassword() {
return confirmPassword;
}
public void setConfirmPassword(String confirmPassword) {
this.confirmPassword = confirmPassword;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public String reg() {
return "success";
}
@SkipValidation
public String toRegView() {
System.out.println("toRegView");
return "regView";
}
}
ActionName-validation.xml

考虑到国际化的关系，如果把验证的错误提示写在验证的配置文件里，这样就没办法做到国际化
此时应该把错误提示放到一个配置文件中。
在action同目录下，新建一个配置文件，命名规则为：ActionName.properties
error.name.length=${name} is goog name,but length must be between ${minLength} and ${maxLength}.在配置文件中定义名字长度错误的信息
此时还需要把此处定义信息的key与验证配置文件关联：
<validators>
<field name="name">
<field-validator type="requiredstring">
<message>name is required</message>
</field-validator>
<field-validator type="stringlength">
<param name="minLength">5</param>
<param name="maxLength">10</param>
<message key="error.name.length" />这里的key与上面关联
</field-validator>
</field>
</validators>
<html>
<head>
<title>reg.jsp</title>
</head>
<body>
<s:actionerror/> 这句是显示密码是否一致的错误消息，与字段错误的消息提示不同
<s:form namespace="/validate" action="ValidateAction_reg" method="post" theme="xhtml">
<s:textfield name="name" label="UserName" />
<s:textfield name="age" label="UserAge" />
<s:textfield name="password" label="password" />
<s:textfield name="confirmPassword" label="confirmPassword" />
<s:submit />
</s:form>
</body>
</html>
注意：上面的校验是服务端校验，如果想让客户端校验，可以在form表单加一个属性
<html>
<head>
<title>reg.jsp</title>
</head>
<body>
<s:actionerror/>
<s:form namespace="/validate" action="ValidateAction_reg" method="post" theme="xhtml" validate="true"> 加这个属性，就是客户端校验
<s:textfield name="name" label="UserName" />
<s:textfield name="age" label="UserAge" />
<s:textfield name="password" label="password" />
<s:textfield name="confirmPassword" label="confirmPassword" />
<s:submit />
</s:form>
</body>
</html>
