因为菜鸟所以这个问题弄了挺久的，这个是时间的问题。

因为springMVC没有没办法把字符串转换成日期类型，所以需要自定义参数绑定

前端控制器接收到请求后，找到注解形式的处理器适配器

所以我在spring-mvc.xml的配置文件中加了这些写代码

/**

spring-mvc.xml

然后再创建一个时间工具类

package zhu.unitl;import java.text.SimpleDateFormat;
import java.util.Date;import org.springframework.core.convert.converter.Converter;
 /**
  * 时间处理
  * @author XiaoZhu
  *
  */
public class DateConverter implements Converter<String, Date>{    @Override
    public Date convert(String source) {
          SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd");
      try {
               return simpleDateFormat.parse(source);          } catch (Exception e) {
               e.printStackTrace();
          }
          return null;
    }}

这些都是上网找了好久的
