[SpringMVC] 1. 파일업로드(File Upload) 설정 부분

Spring MVC 파일업로드 Multipart의 경우 몇가지 설정을 해야합니다.

 

1. pom.xml 파일업로드 관련 의존성 추가

<!--  파일업로드  -->
        <dependency>
            <groupId>commons-fileupload</groupId>
            <artifactId>commons-fileupload</artifactId>
            <version>1.3.2</version>
        </dependency> <!-- https://mvnrepository.com/artifact/commons-io/commons-io -->
        <dependency>
            <groupId>commons-io</groupId>
            <artifactId>commons-io</artifactId>
            <version>2.5</version>
        </dependency>
        <!--  파일업로드  -->

2. dispatcher-servlet.xml(이클립스 경우, servlet-context.xml)에 multipart 부분 설정 

 <!-- 파일업로드 관련 Mulitipart 설정 -->
    <beans:bean id="multipartResolver"
                class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!-- 
        	setting maximum upload size
            최대 크기 설정
            <beans:property name="maxUploadSize" value="-1"/>
        -->
        <beans:property name="maxUploadSize" value="209715200"/> <!-- 20MB --> <!-- max size of file in memory (in bytes) -->
        <beans:property name="maxInMemorySize" value="1048576"/> <!-- 1MB -->
    </beans:bean>

3. web.xml에 multipart 부분 설정

 <!-- MultipartFilter 적용 -->
    <filter>
        <filter-name>MultipartFilter</filter-name>
        <filter-class>org.springframework.web.multipart.support.MultipartFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>MultipartFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
