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=u540Du79F0u4E0Du80FDu4E3Au7A7Au3002 age.not.inrange=u5E74u9F84u8D85u51FAu8303u56F4u3002 email.not.correct=u90AEu7BB1u5730u5740u4E0Du6B63u786Eu3002 email.not.empty=u7535u5B50u90AEu4EF6u4E0Du80FDu60DFu6050u3002
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. |

|
@Range(min=最小值, max=最大值) |
|

|
@NotBlank |
|
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) |
|

|
|
|
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 |
