spring驗證框架

1.applicationContext.xml

 

//spring 驗證對應的message資源.
<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
		<property name="basenames">
			<list>
				<value>WEB-INF/classes/message</value>
			</list>
		</property>
	</bean>
	
   	<bean id="beanValidator" class="org.springmodules.validation.commons.DefaultBeanValidator">
		<property name="validatorFactory" ref="validatorFactory"/>
	</bean>

    <bean id="validatorFactory" class="org.springmodules.validation.commons.DefaultValidatorFactory">
		<property name="validationConfigLocations">
			<list>
				<value>/WEB-INF/validator-rules.xml</value>
				<value>/WEB-INF/validator.xml</value>
			</list>
		</property>
	</bean>

 2.validator-ruls.xml 網上有。

 3.validator.xml自己定義的規則：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE form-validation PUBLIC 
    "-//Apache Software Foundation//DTD Commons Validator Rules Configuration 1.1//EN" 
    "http://jakarta.apache.org/commons/dtds/validator_1_1.dtd">
