使用Spirng 3 MVC很方便；使用它的validation同样。。
使用方法
1. 依赖两个包
<!-- JSR 303 with Hibernate Validator -->
<dependency>
<groupId>javax.validation</groupId>
<artifactId>validation-api</artifactId>
<version>1.0.0.GA</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>4.1.0.Final</version>
</dependency>
2. model里加验证具体方式如下：
参考如下http://stackoverflow.com/questions/9993447/two-ways-to-use-spring-3-validation
使用发现错误：
严重: Servlet.service() for servlet dispatcher threw exception

其原因是：
public String save(@Valid Organization organization, ModelMap model, BindingResult errorResult) {
if (errorResult.hasErrors()) {
return "organization.add";
}
}
上面方法中ModelMap model,参数应该放到BindingResult errorResult后面，就对了
