1）模型类

 public class goods {     //goods.gname.required错误消息 key（国际化后对应的就是国际化的信息）     @notblank(message="{goods.gname.required}")     private string gname;     @notblank(message="{goods.gdesciption.required}")     private string gdescription;     @range(min=0,max=100,message="{gprice.invalid}")     private double gprice;     // 日期格式化（需要在配置文件中配置formattingconversionservicefactorybean)     @datetimeformat(pattern = "yyyy-mm-dd")     @past(message="{gdate.invalid}")     private date gdate;     //省略setter和getter方法

2）控制器类

 package controller;  import javax.annotation.resource; import org.apache.commons.logging.log; import org.apache.commons.logging.logfactory; import org.springframework.beans.factory.annotation.autowired; import org.springframework.stereotype.controller; import org.springframework.ui.model; import org.springframework.validation.bindingresult; import org.springframework.validation.validator; import org.springframework.web.bind.annotation.modelattribute; import org.springframework.web.bind.annotation.requestmapping; import pojo.goods; import service.goodsservice;  @controller @requestmapping("/goods") public class goodscontroller {     // 得到一个用来记录日志的对象，这样在打印信息的时候能够标记打印的是哪个类的信息     private static final log logger = logfactory.getlog(goodscontroller.class);     @autowired     private goodsservice goodsservice;     @requestmapping("/input")     public string input(model model) {         // 如果model中没有goods属性，addgoods.jsp会抛出异常         // 因为表单标签无法找到modelattribute属性指定的form backing object         model.addattribute("goods", new goods());         return "addgoods";     }      @requestmapping("/save")     public string save(@modelattribute goods goods, bindingresult result,model model) {         if (result.haserrors()) {             return "addgoods";         }         goodsservice.save(goods);         logger.info("添加成功");         model.addattribute("goodslist", goodsservice.getgoods());         return "goodslist";     } }

3）配置文件

                                                                           /web-inf/resource/errormessages
