你会发现你只要写一个新的东西，或者想用ssm框架新的功能时，一般都会进行下面两步，导入需要的jar包和写配置文件，当然利用Hibernate Validator实现ssm的数据校验也不例外。
1、需要的jar包（注意各个jar之间可能存在版本不兼容）
hibernate-validator-5.0.0.CR2.jar classmate-0.8.0.jar jboss-logging-3.1.1.GA.jar
validation-api-1.1.0.CR1.jar hibernate-validator-annotation-processor-5.0.0.CR2.jar

2、配置文件
我相信你如果学这个那么你的其它的配置文件一定写好了，那我将springmvc的配置文件写给大家，大家可以进行参考
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="

<!-- 将控制器所在包 加入IOC容器 -->
<context:component-scan base-package="org.library.controller,org.library.service.impl"></context:component-scan>
<!-- 配置视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/views/pages/"></property>
<property name="suffix" value=".jsp"></property>
<property name="order" value="2"></property>
</bean>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<property name="prefix" value="/" />
<property name="suffix" value=".jsp" />
<property name="order" value="1"></property>
</bean>
<!-- 释放静态资源 -->

<mvc:resources location="/static/css/" mapping="/static/css/**"/>
*<!-- 表单验证框架 --> <!-- 配置开启注解 协调资源--> <!-- 这俩个配置文件必须写切记-->
**<!-- 表单验证框架 -->

<property name="providerClass" value="org.hibernate.validator.HibernateValidator"></property>
</bean>

<mvc:default-servlet-handler/>
<!-- 俩个都写的话没有tequestmapping直接交给setvert处理 -->**
<!-- 配置json注释 -->

</list>
</property>
</bean>
<bean id="mappingJackson2HttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="supportedMediaTypes">
<list>

<value>application/json;charset=utf-8</value>
</list>
</property>
</bean>
</list>
</property>
</bean>
</beans>
既然进行数据校验，那么我们以注册老师为例进行这个功能的详细的讲解
2、实体类
就是在你的实体的前边进行数据校验，把你要想的格式卸载属性的前边即可。关于注解使用你可以看下面的这篇博客：https://www.cnblogs.com/myitmylife/p/3617084.html
package org.library.entity;
import javax.validation.constraints.Pattern;
import org.hibernate.validator.constraints.Email;
import org.hibernate.validator.constraints.NotBlank;
import org.hibernate.validator.constraints.NotEmpty;
public class logintest {
@NotBlank(message="姓名不能为空")
public String teaname;
@NotBlank(message="密码不能为空")
public String teapassword;
@Pattern(regexp="[男女]",message="只能为男或者女,且不能为空")
public String teasex;
@NotBlank(message="电话不能为空")
public String teaphone;
@NotBlank(message="邮箱不能为空")
@Email(message="邮箱格式不正确")
public String teaemail;
@NotBlank(message="电话不能为空")
public String teaschoolname;
public String getTeaname() {
return teaname;
}
public void setTeaname(String teaname) {
this.teaname = teaname;
}
public String getTeapassword() {
return teapassword;
}
public void setTeapassword(String teapassword) {
this.teapassword = teapassword;
}
public String getTeasex() {
return teasex;
}
public void setTeasex(String teasex) {
this.teasex = teasex;
}
public String getTeaphone() {
return teaphone;
}
public void setTeaphone(String teaphone) {
this.teaphone = teaphone;
}
public String getTeaemail() {
return teaemail;
}
public void setTeaemail(String teaemail) {
this.teaemail = teaemail;
}
public String getTeaschoolname() {
return teaschoolname;
}
public void setTeaschoolname(String teaschoolname) {
this.teaschoolname = teaschoolname;
}
}
3、controller实现
package org.library.controller;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.validation.Valid;
import org.library.entity.logintest;
import org.springframework.stereotype.Controller;
import org.springframework.validation.BindingResult;
import org.springframework.validation.FieldError;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping("logintestcontroller")
public class logintestcontroller {
@RequestMapping("test")
public ModelAndView test(@Valid logintest ls,BindingResult result) {//indingResult result就是将logintest ls错误的信息放在request中
System.out.println("test");
//实现将错误的信息放在map中返回前台，对于下面的使用方法 不会的建议各自的进行百度学习
Map< String, Object> map=new HashMap<String, Object>();
List<FieldError> errors=result.getFieldErrors();
if(result.hasErrors()) {
for(FieldError fielderror:errors) {
map.put(fielderror.getField(), fielderror.getDefaultMessage());
}
return new ModelAndView("logintest",map);
}else {
return new ModelAndView("success");
}
}
}
4、前台的代码
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<base href="<%=basePath %>" />
<link rel="stylesheet" href="//cdn.bootcss.com/bootstrap/3.3.5/css/bootstrap.min.css">
<link rel="stylesheet" href="//cdn.bootcss.com/bootstrap/3.3.5/css/bootstrap-theme.min.css">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

<body>

<h3>添加教师</h3>
<form action="logintestcontroller/test" method="post" class="form-horizontal">

</tr>
<tr>

<td><input type="text" name="teaschoolname"></td>
<td style=" color:#CC3300">${teaschoolname}</td>
</tr>
</table>
</div>
<input type="submit" value="确认添加" class="btn btn-default">
</form>
</center>
</body>
</html>
你没有进行了解Hibernate Validator进行数据校验的话，本人不建议，建议了解Hibernate Validator的工作流程，在进行Hibernate Validator的学习。
对此我也给大家提供一些学习资料，对于ssm学习建议大家到腾讯课堂搜索颜群老师，他对于javaweb讲的比较多，而且比较实用。
