struts2文件上传突破2M限制

struts配置文件

<action name="upload" class="strutsFileUpload">
            <result name="input" type="redirect">/admin/ChangePhoto.jsp</result>
            <result name="adminSuccess" type="redirect">/admin/index2.jsp</result>
            <result name="userSuccess" type="redirect">/admin/index.jsp</result>
            <interceptor-ref name="defaultStack">
            	<param name="fileUpload.maximumSize">1000000000</param>
            	<param name="fileUpload.allowedTypesSet">image/jpg,image/png,image/jpeg</param>
            </interceptor-ref>
        </action>

在最上面加一句

<constant name="struts.multipart.maxSize" value="9000000"/>

就可以5M 其他的类推

<struts>
<constant name="struts.i18n.encoding" value="GBK"></constant>
<constant name="struts.multipart.maxSize" value="9000000"/>
<package name="fileUpload" namespace="/" extends="struts-default">
        <action name="showUpload">
            <result>/admin/ChangePhoto.jsp</result>
        </action>

        <action name="upload" class="strutsFileUpload">
            <result name="input" type="redirect">/admin/ChangePhoto.jsp</result>
            <result name="adminSuccess" type="redirect">/admin/index2.jsp</result>
            <result name="userSuccess" type="redirect">/admin/index.jsp</result>
            <interceptor-ref name="defaultStack">
            	<param name="fileUpload.maximumSize">1000000000</param>
            	<param name="fileUpload.allowedTypesSet">image/jpg,image/png,image/jpeg</param>
            </interceptor-ref>
        </action>
