springmvc+apache表单验证框架集成。
1.依赖的jar
<dependency>
<groupId>org.springmodules</groupId>
<artifactId>spring-modules-validation</artifactId>
<version>0.8</version>
</dependency>
2.spring的xml中配置：
<!-- 资源文件-->
<bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
<property name="basename" value="messages" />
</bean>
<!--基于apache的表单验证框架-->
<bean id="defaultValidatorFactory" class="org.springmodules.validation.commons.DefaultValidatorFactory">
<property name="validationConfigLocations">
<list>
<value>classpath:/validation/validation.xml</value>
<value>classpath:/validation/validator-rules.xml</value>
<value>classpath:/validation/validation-account.xml</value>
</list>
</property>
</bean>
<!-- 验证-->
