1、maven

<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.1.0.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>4.2.0.Final</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.7</version>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjweaver</artifactId>
<version>1.8.4</version>
</dependency>

2、修改配置文件applicationContex.xml

<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>

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

validator="validator"是上面定义的id

3、新建validationMessages.properties 文件放到resources文件夹中，内容如下

name.not.empty=1111111

111111内容可自定义

4、新建实体类

package com.db.pojo;

import javax.validation.constraints.NotNull;

import org.hibernate.validator.constraints.NotBlank;
import org.hibernate.validator.constraints.NotEmpty;

public class User {

@NotEmpty(message="{name.not.empty}")
private String userName;

private String password;

public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}

}

name.not.empty 为validationMessages.properties里面配置的名称

@NotEmpty代表不能为空，可从网上查询其它验证标签

5、查看controller

@RequestMapping(value="/userlogin", method = {RequestMethod.GET})
public String userLogin(Model model){

if(!model.containsAttribute("contentModel")){
model.addAttribute("contentModel", new User());
}
return "userlogin";
}

@RequestMapping(value="/userlogin", method = {RequestMethod.POST})
public String userLogin(@Valid  @ModelAttribute("contentModel")  User user, BindingResult result){

Map<String, Object> map = new HashMap<String, Object>();
if(result.hasErrors()){
return "/userlogin";
}
else {
return "/index";
}

}

6、jsp页面

<%@ page language="java"  pageEncoding="UTF-8" contentType="text/html;charset=UTF-8" %>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>

<html>
<head>
<title>Reservation Form</title>

<style>
.error {
color: #ff0000;
font-weight: bold;
}
</style>
</head>

<body>
<form:form method="post" modelAttribute="contentModel" action="userlogin">
<form:errors path="*" cssClass="error" />
<table>
<tr>
<td>Name</td>
<td><form:input path="userName" />
</td>
<td><form:errors path="userName" cssClass="error" />
</td>
</tr>
<tr>
<td>password</td>
<td><form:input path="password" />
</td>
<td><form:errors path="password" cssClass="error" />
</td>
</tr>

<tr>
<td colspan="3"><input type="submit" />
</td>
</tr>
</table>
</form:form>
</body>
</html>

访问http://****/userlogin 点击submit 按钮会提示 1111111（就是validationMessages.properties文件中配置的内容）
