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，到注解形式的处理器适配器
所以我在l的配置⽂件中加了这些写代码
/**
* 时间的新增必须要经过处理，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

* <!-- ⽇期转换必须放在<mvc:annotation-driven />前⾯ -->
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"></bean>
<!-- 注解⽅式 -->
<mvc:annotation-driven  conversion-service="conversionService">

<!-- 配置⽇期转换器 -->

<!--mvc配置视图解析  -->
<!-- 对模型视图名称的解析，即在模型视图名称添加前后缀 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

</bean>
<!--跳转的时候只⽤写jsp名字，不⽤带后缀，因为默认的后缀“.jsp”，路径为“/WEB-INF/jsp”  -->
</beans>
然后再创建⼀个时间⼯具类
package zhu.unitl;
SimpleDateFormat;
import java.util.Date;
import verter.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;
}
}
这些都是上⽹了好久的
