    //校验名字1到30个字符中间

user.name.length.error=请输入1到30个字符的名字
user.num.noNull=请输入商品的生产日期

@RequestMapping(value = "updateUser")
public String updateUser(@Validated User user, BindingResult bindingResult){
    List<ObjectError> allErrors = bindingResult.getAllErrors();
    //获得错误信息
    for(ObjectError e : allErrors){
        //输出错误信息
        System.out.println(e.getDefaultMessage());   
    }
    try{
        int count = userService.updateUser(user);
    } catch(Exception e){
        e.printStackTrace();
    }
    return "message";
} 

//校验名字1到30个字符中间
//message是提示校验出错信息
//标识此校验属于哪个分组，group也可属于多个分组
@Size(min=1, max=30, message="{user.name.length.error}", groups={Validation1.class})
private String name;

@Validated中的参数指向那个检验分组
@RequestMapping(value = "updateUser")
public String updateUser(@Validated(value={Validation1.class}) User user, BindingResult bindingResult){
    if(bindingResult.hasErrors()){
        List<ObjectError> allErrors = bindingResult.getAllErrors();
        //获得错误信
       for(ObjectError e : allErrors){
            //输出错误信息
            System.out.println(e.getDefaultMessage());
        }
    }
    try{
        int count = userService.updateUser(user);
    } catch(Exception e){
        e.printStackTrace();
    }
    return "message";
}
