spring集成JSR-303验证框架--Hibernate-validator实现

基于Maven和Spring的配置

		<dependency>
			<groupid>javax.validation</groupid>
			<artifactid>validation-api</artifactid>
		</dependency>

		<dependency>
			<groupid>org.hibernate</groupid>
			<artifactid>hibernate-validator-annotation-processor</artifactid>
		</dependency>
		<dependency>
			<groupid>org.hibernate</groupid>
			<artifactid>hibernate-validator</artifactid>
		</dependency>

spring的配置

	
    <bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
        <property name="providerClass" value="org.hibernate.validator.HibernateValidator">
        <!--不设置则默认为classpath下的 ValidationMessages.properties -->
        <property name="validationMessageSource" ref="validatemessageSource">
    </property></property></bean>
    <bean id="validatemessageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">  
        <property name="basename" value="classpath:ValidationMessages">  
        <property name="fileEncodings" value="utf-8">  
        <property name="cacheSeconds" value="120">  
    </property></property></property></bean>

提示内容放到类路径的ValidationMessages.properties下，这样方便部署不用重新编译和国际化，

password.not.rule=密码 is not rule
password.is.null=PWD can not null

java中取值就用{key值}

package com.wei.service.vo;

import java.math.BigDecimal;
import java.util.Date;

import org.hibernate.validator.constraints.NotBlank;

import com.wei.dao.entity.User;

public class UserVo {

	private String name;
	@NotBlank(message = "{password.is.null}")
	// @PwdRule(message="{password.not.rule}")
	private String password;
	private BigDecimal weight;
	private Date createDate;
	private User user;

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public BigDecimal getWeight() {
		return weight;
	}

	public void setWeight(BigDecimal weight) {
		this.weight = weight;
	}

	public Date getCreateDate() {
		return createDate;
	}

	public void setCreateDate(Date createDate) {
		this.createDate = createDate;
	}

	public User getUser() {
		return user;
	}

	public void setUser(User user) {
		this.user = user;
	}
}

统一验证的请参考Spring AOP基础上一篇文章

下面是主要的验证注解及说明：

注解	适用的数据类型	说明
@AssertFalse	Boolean, boolean	验证注解的元素值是false
@AssertTrue	Boolean, boolean	验证注解的元素值是true
@DecimalMax（value=x）	BigDecimal, BigInteger, String, byte,short, int, long and the respective wrappers of the primitive types. Additionally supported by HV: any sub-type of Number andCharSequence.	验证注解的元素值小于等于@ DecimalMax指定的value值
@DecimalMin（value=x）	BigDecimal, BigInteger, String, byte,short, int, long and the respective wrappers of the primitive types. Additionally supported by HV: any sub-type of Number andCharSequence.	验证注解的元素值小于等于@ DecimalMin指定的value值
@Digits(integer=整数位数, fraction=小数位数)	BigDecimal, BigInteger, String, byte,short, int, long and the respective wrappers of the primitive types. Additionally supported by HV: any sub-type of Number andCharSequence.	验证注解的元素值的整数位数和小数位数上限
@Future	java.util.Date, java.util.Calendar; Additionally supported by HV, if theJoda Time date/time API is on the class path: any implementations ofReadablePartial andReadableInstant.	验证注解的元素值（日期类型）比当前时间晚
@Max（value=x）	BigDecimal, BigInteger, byte, short,int, long and the respective wrappers of the primitive types. Additionally supported by HV: any sub-type ofCharSequence (the numeric value represented by the character sequence is evaluated), any sub-type of Number.	验证注解的元素值小于等于@Max指定的value值
@Min（value=x）	BigDecimal, BigInteger, byte, short,int, long and the respective wrappers of the primitive types. Additionally supported by HV: any sub-type of CharSequence (the numeric value represented by the char sequence is evaluated), any sub-type of Number.	验证注解的元素值大于等于@Min指定的value值
@NotNull	Any type	验证注解的元素值不是null
@Null	Any type	验证注解的元素值是null
@Past	java.util.Date, java.util.Calendar; Additionally supported by HV, if theJoda Time date/time API is on the class path: any implementations ofReadablePartial andReadableInstant.	验证注解的元素值（日期类型）比当前时间早
@Pattern(regex=正则表达式, flag=)	String. Additionally supported by HV: any sub-type of CharSequence.	验证注解的元素值与指定的正则表达式匹配
@Size(min=最小值, max=最大值)	String, Collection, Map and arrays. Additionally supported by HV: any sub-type of CharSequence.	验证注解的元素值的在min和max（包含）指定区间之内，如字符长度、集合大小
@Valid	Any non-primitive type（引用类型）	验证关联的对象，如账户对象里有一个订单对象，指定验证订单对象
@NotEmpty	CharSequence,Collection, Map and Arrays	验证注解的元素值不为null且不为空（字符串长度不为0、集合大小不为0）
@Range(min=最小值, max=最大值)	CharSequence, Collection, Map and Arrays,BigDecimal, BigInteger, CharSequence, byte, short, int, long and the respective wrappers of the primitive types	验证注解的元素值在最小值和最大值之间
@NotBlank	CharSequence	验证注解的元素值不为空（不为null、去除首位空格后长度为0），不同于@NotEmpty，@NotBlank只应用于字符串且在比较时会去除字符串的空格
@Length(min=下限, max=上限)	CharSequence	验证注解的元素值长度在min和max区间内
@Email	CharSequence	验证注解的元素值是Email，也可以通过正则表达式和flag指定自定义的email格式
