[Spring] Spring 파일업로드 & Postman 파일업로드 테스트

1. 환경

Spring Framework

tomcat 8.5

Postman 9.31.0

2. 세팅

1) pom.xml

<!-- https://mvnrepository.com/artifact/commons-io/commons-io -->
<dependency>
    <groupId>commons-io</groupId>
    <artifactId>commons-io</artifactId>
    <version>2.2</version>
</dependency>

<!-- https://mvnrepository.com/artifact/commons-fileupload/commons-fileupload -->
<dependency>
    <groupId>commons-fileupload</groupId>
    <artifactId>commons-fileupload</artifactId>
    <version>1.3.1</version>
</dependency>

2) web.xml

<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>

3) bean 등록

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
	<property name="maxUploadSize" value="100000000" />
	<property name="maxInMemorySize" value="100000000" />
</bean>

나는 dispatcher-servlet.xml 에 추가했다.

환경에 따라 다를 수 있음!

4) context.xml

<Context allowCasualMultipartParsing="true" path="/">

    <!-- Default set of monitored resources. If one of these changes, the    -->
    <!-- web application will be reloaded.                                   -->
    <WatchedResource>WEB-INF/web.xml</WatchedResource>
    <WatchedResource>${catalina.base}/conf/web.xml</WatchedResource>
    <!-- Uncomment this to disable session persistence across Tomcat restarts -->
    <!--
    <Manager pathname="" />
    -->
</Context>

allowCasualMultipartParsing="true" path="/" 를 추가해줘야 한다.

1~3번 설정하고 다른 사람들꺼 코드 복붙해도 오류가 와장창 나서 뭔가.. 했는데

저걸 추가 했더니 깔끔하게 실행됐다ㅎㅎ

3. 소스

@RequestMapping(value = "/fileUpload.do" )
@ResponseBody
public ResultVo fileUpload(MultipartFile file, HttpServletResponse response) {
	ResultVo result = new ResultVo();
    	
	try {
		Map<String, String> dataMap = new HashMap<>();
		dataMap.put("ContentType", file.getContentType());
		dataMap.put("OriginalFilename", file.getOriginalFilename());
		dataMap.put("Size", String.valueOf(file.getSize()));
		result.setData(dataMap);
	} catch (Exception e) {
		// TODO: handle exception
		e.printStackTrace();
	}
    
	return result;
}

url 호출시 key값을 file로 보내기 때문에 @RequestParam("file")은 생략 가능하다.
