国际化是为了实现不同地区页面呈现不同的语言问题；

编写程序实现国际化，在xml文件中做响应的配置，然后编写.properties文件即可。

实现登录界面的中英文切换：

xml文件配置：

<mvc:annotation-driven validator="validator" conversion-service="conversion-service"/>
        <bean id="conversion-service" class="org.springframework.format.support.FormattingConversionServiceFactoryBean"/>
        
        <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
            <property name="basenames" value="message"/>
        </bean>
        
        <bean id="localeResolver" class="org.springframework.web.servlet.i18n.SessionLocaleResolver"/> 
        <mvc:interceptors>
          <bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor"/> 
        </mvc:interceptors>
        <bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
            <property name="providerClass" value="org.hibernate.validator.HibernateValidator"/>
            <property name="validationMessageSource" ref="messageSource"></property>
        </bean>

entity实现类通过注解验证：

public class User {
    
    	@Size(min=3,max=50,message="{fullName}")
    	private String fullName;
    	
    	@Size(min=3,max=20,message="{userName}")
    	//@Pattern(regexp="^[a-zA-Z0-9]+$",message="用户姓名之间不能存在空格")	
    	private String userName;
    	
    	@Size(min=6,max=20,message="{password}")
    	private String password;
    	
    	@Pattern(regexp="[A-Za-z0-9._%+-]+@[A-Za-z0-9]+.[A-Za-z]{2,4}",message="{email}")
    	private String email;
