Spring mvc时间格式处理

spring mvc中，如果时间格式是yyyy-MM-dd，传入后台会报错，要增加一些配置才可以。

1.修改spring-mvc.xml,增加org.springframework.format.support.DefaultFormattingConversionService

<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"/>
    <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
        <property name="messageConverters">
            <list>
                <ref bean="mappingFastJsonHttpMessageConverter"/> <!-- JSON转换器 -->
            </list>
        </property>
        <property name="webBindingInitializer">
            <bean class="org.springframework.web.bind.support.ConfigurableWebBindingInitializer">
                <property name="conversionService" ref="conService" />
            </bean>
        </property>
    </bean>

    <bean id="conService" class="org.springframework.format.support.DefaultFormattingConversionService"/>

2.在实体属性处增加DateTimeFormat注解

 @DateTimeFormat(pattern = "yyyy-MM-dd")
    private Date reqisterDate;
