Struts2校验

第一种方法：普通配置文件校验

在Action所在包下建立Action-validation.xml或Action-method-validation.xml，前者是对Action中所有的方法进行校验，而后者是对某一个method进行校验，具体格式如下（对用户姓、名、年龄校验）

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0.2//EN"
"http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">
<validators>
	<field name="user.firstname">
		<field-validator type="requiredstring">
			<message>required first name</message>
		</field-validator>
	</field>
	<field name="user.lastname">
		<field-validator type="requiredstring">
			<message>required last name</message>
		</field-validator>
	</field>	
	<field name="user.age">
		<field-validator type="required">
			<message>required age</message>
		</field-validator>
		<field-validator type="int">
			<param name="min">1</param>
			<param name="max">150</param>
			<message>age should be between ${min} and ${max}</message>
		</field-validator>
	</field>
</validators>

 

第二种方法：使用visitor进行校验

第一：先在Action包下建立Action-validation.xml或Action-method-validation.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0.2//EN"
"http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd"> 
<validators>
 	<field name="user">
 		<field-validator type="visitor">
 			<param name="context">user</param><!-- 具体的校验文件 -->
 			<param name="appendPrefix">true</param><!-- 是否添加前缀 -->
 			<message>user's </message><!-- 前缀 -->
 		</field-validator>
 	</field>
 </validators>

   第二：在Bean所在的包下建立BeanName-contextValue-validation.xml

 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0.2//EN"
"http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">
<validators>
	<field name="firstname">
		<field-validator type="requiredstring">
			<message>firstname required</message>
		</field-validator>
	</field>
	<field name="lastname">
		<field-validator type="requiredstring">
			<message>lastname required</message>
		</field-validator>
	</field>
	<field name="age">
		<field-validator type="required">
			<message>age required</message>
		</field-validator>
	</field>
	<field name="age">
		<field-validator type="int">
			<param name="max">150</param>
			<param name="min">1</param>
			<message>age should be between ${min} and ${max}</message>
		</field-validator>
	</field>
</validators>

 第三：重写validater方法进行校验(略)
