因為菜鳥所以這個問題弄了挺久的，這個是時間的問題。

因為springMVC沒有沒辦法把字符串轉換成日期類型，所以需要自定義參數綁定

前端控制器接收到請求后，找到注解形式的處理器適配器

所以我在spring-mvc.xml的配置文件中加了這些寫代碼 

/**
 * 時間的新增 必須要經過處理，因為springMVC沒有沒辦法把字符串轉換成日期類型。所以需要自定義參數綁定
 * 前端控制器接收到請求后，找到注解形式的處理器適配器，
 * <!-- 日期轉換  必須放在<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>
<!-- 配置日期轉換器 -->
<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
   <property name="converters">
       <set>
           <bean class="zhu.util.DateConverter"></bean>
       </set>
   </property>
</bean>

然后再創建一個時間工具類 

package zhu.unitl;

import java.text.SimpleDateFormat;
import java.util.Date;

import org.springframework.core.convert.converter.Converter;
 /**
  * 時間處理
  * @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;
    }

}

 

這些都是上網找了好久的
