SpringMVC整合MyBatis 實現商品信息提交功能時報錯Field error in object 'itemsCustom' on field 'createtime'

附上完整錯誤信息：

錯誤原因是我在用MyBatis逆向工程自動生成po類時定義的createtime爲java.util.Date類型（錯誤信息中的itemsCustom爲createtime所在商品信息類的擴展類），而修改商品信息頁面的jsp文件中規定createtime的相關信息如下

 

即二者的日期格式不一致導致了該錯誤的產生

 

解決方法：

1.在相關的controller.java文件中增加數據綁定代碼：

 

@InitBinder
	public void initBinder(WebDataBinder binder) {
	        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
	        dateFormat.setLenient(false);
	        binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));
	 }

應導入的相關類有：

 

2.也可以自定義日期類型綁定，即加入一個日期類型轉換器

 

public class CustomDateConverter implements Converter<String,Date>{
	public Date convert(String source) {
		SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");	
		try {
			return simpleDateFormat.parse(source);
		} catch (ParseException e) {
			e.printStackTrace();
		}
		return null;
	}
}

並在SpringMVC的配置文件中配置：

 

 

<mvc:annotation-driven conversion-service="conversionService"></mvc:annotation-driven>
<!-- 自定義參數綁定 -->
<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
	<!-- 轉換器 -->
	<property name="converters">
		<list>
			<!-- 日期類型轉換 -->
			<bean class="ssm.controller.converter.CustomDateConverter"/>
		</list>
	</property>
</bean>
