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
/** * 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 * 前端控制器接收到请求后，找到注解形式的处理器适配器， * <!-- 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"> </mvc:annotation-driven> <!-- 配置日期转换器 --> <bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean"> <property name="converters"> <set> <bean class="zhu.util.DateConverter"></bean> </set> </property> </bean>

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
