1、validation在springmvc中的配置信息如下

<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
             <property name="providerClass" value="org.hibernate.validator.HibernateValidator"/>
             <property name="validationMessageSource" ref="validatemessageSource"/>
        </bean>
        <bean id="validatemessageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
            <property name="basenames">
                <list>
                    <value>classpath:config/CustomValidationMessages</value>
                </list>
            </property>
             <property name="fileEncodings" value="utf-8" />
             <property name="cacheSeconds" value="120"/>
        </bean>

<mvc:annotation-driven conversion-service="conversionService" validator="validator"></mvc:annotation-driven>

2、

CustomValidationMessages.properties文件

#添加校验错误提交信息 iterms.name.length.error=请输入1到30个字符的商品名称 iterms.price.isNull=请输入商品价格

3、在pojo类校验

import javax.validation.constraints.NotNull;
    import javax.validation.constraints.Size;
    import java.util.Date;
     public class Iterms {
        private Integer id;
    
    /* 校验名称在1到30字符中间 message是提示校验出错显示的信息 */ @Size(min=1,max=30,message ="{iterms.name.length.error}" )
        private String goodName;
    /* 非空校验 */ @NotNull(message="{iterms.price.isNull}")

private Integer price;

}

#添加校验错误提交信息 iterms.name.length.error=请输入1到30个字符的商品名称 iterms.price.isNull=请输入商品价格
