springmvc JSR303 Validate 注解式，校验数据

参考：http://www.cnblogs.com/liukemng/category/578644.html

先进行配置：

<!-- 默认的注解映射的支持 -->

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

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property>

        <property name="prefix" value="/WEB-INF/views/"></property>

        <property name="suffix" value=".jsp"></property>

    </bean>

    <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"/>

    </bean>

    <bean id="conversion-service" class="org.springframework.format.support.FormattingConversionServiceFactoryBean" />

    <bean id="validatemessageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">

        <property name="basename" value="classpath:validatemessages"/>

        <property name="fileEncodings" value="utf-8"/>

        <property name="cacheSeconds" value="120"/>

    </bean>

model:

import org.hibernate.validator.constraints.Email;

import org.hibernate.validator.constraints.NotEmpty;

import org.hibernate.validator.constraints.Range;

public class ValidateModel{

    @NotEmpty(message="{name.not.empty}")

    private String name;

    @Range(min=0, max=150,message="{age.not.inrange}")

    private String age;

    @NotEmpty(message="{email.not.empty}")

    @Email(message="{email.not.correct}")

    private String email;

    public void setName(String name){

        this.name=name;

    }

    public void setAge(String age){

        this.age=age;

    }

    public void setEmail(String email){

        this.email=email;

    }

    public String getName(){

        return this.name;

    }

    public String getAge(){

        return this.age;

    }

    public String getEmail(){

        return this.email;

    }

}

validatemessages.properties

name.not.empty=\u540D\u79F0\u4E0D\u80FD\u4E3A\u7A7A\u3002

age.not.inrange=\u5E74\u9F84\u8D85\u51FA\u8303\u56F4\u3002

email.not.correct=\u90AE\u7BB1\u5730\u5740\u4E0D\u6B63\u786E\u3002

email.not.empty=\u7535\u5B50\u90AE\u4EF6\u4E0D\u80FD\u60DF\u6050\u3002

validatetest.jsp:(用于提交数据的表单页面)

<form:form modelAttribute="contentModel" method="post">

    <form:errors path="*"></form:errors><br/><br/>

    name：<form:input path="name" /><br/>

    <form:errors path="name"></form:errors><br/>

    age：<form:input path="age" /><br/>

    <form:errors path="age"></form:errors><br/>

    email：<form:input path="email" /><br/>

    <form:errors path="email"></form:errors><br/>

    <input type="submit" value="Submit" />

</form:form>

validatesuccess.jsp:(验证通过后，跳转的页面)

<body>

验证成功！

</body>

from表单请求式：

controller:

/**

     * 请求该地址，进入表单页

     * @param model

     * @return

     */

    @RequestMapping(value="/test", method = {RequestMethod.GET})

    public String test(Model model){

        if(!model.containsAttribute("contentModel")){

            model.addAttribute("contentModel", new ValidateModel());

        }

        return "validatetest";

    }

/**

     * 请求该地址，校验数据

     * @param model

     * @param validateModel

     * @param result

     * @return

     */

    @RequestMapping(value="/test", method = {RequestMethod.POST},produces = "text/html")

    public String test2(Model model,@Valid @ModelAttribute("contentModel") ValidateModel validateModel,BindingResult result) {

        //如果有验证错误 返回到form页面

        if(result.hasErrors()) {

            test(model);

        }

        return "validatesuccess";

    }

bindingresult里有校验的结果，model里会携带bindingresult，然后在jsp页面渲染错误信息！

结果示例：

AJAX请求式：

/**

     * ajax 验证数据

     * @param validateModel

     * @param result

     * @return

     */

    @RequestMapping(value="/test", method = {RequestMethod.POST},produces = "text/html;charset=UTF-8")

    @ResponseBody

    public String test(@Valid ValidateModel validateModel, BeanPropertyBindingResult result) {

        if(result.hasErrors()) {

            StringBuilder sb  = new StringBuilder();

            List<ObjectError> lit = result.getAllErrors();

            for (ObjectError objectError : lit) {

                FieldError error = (FieldError)objectError;

                String a = error.getDefaultMessage();

                sb.append(a);

            }

            return sb.toString();

        }

        return "success";

    }

        $("#test").click(function () {

            $.ajax({

                url:"test",

                type:"post",

                data:"name=&age=&email=1",

                success:function (result) {

                    alert(result);

                }

            });

        });

这个controller，重点是，我将bindingresult 替换城了 BeanPropertyBindingResult 对象了，因为从这个对象里，能将错误的信息获取出来。

然后将错误的信息拼接返回。结果：

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
