spring mvc问题解决汇总

<form:form> 标签 中有enctype="multipart/form-data"

会出现controll取不到对象值

 

1，spring-config.xml增加以下代码

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
            <property name="maxUploadSize" value="1048576" />
            <property name="defaultEncoding" value="utf8" />
    </bean>

 

2，加入lib包:

commons-io-1.4.jar

commons-fileupload-1.2.1.jar
