spring 3.1에서 Servlet 3.0 적용

web.xml 에서 아래와 같이 수정한다.

<servlet> 
        <servlet-name>spring</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:/spring-servlet.xml</param-value>
        </init-param>
        <multipart-config>
            <max-file-size>52428800</max-file-size>
            <max-request-size>52428800</max-request-size>
            <file-size-threshold>0</file-size-threshold>
        </multipart-config>
    </servlet>
 
    <bean id="multipartResolver"     class="org.springframework.web.multipart.support.StandardServletMultipartResolver">
    </bean>

//Controller
Collection<Part> parts = req.getParts();
        for(Part part : parts) {
            System.out.println("Name:");
            System.out.println(part.getName());
            System.out.println("Header: ");
            for(String headerName : part.getHeaderNames()) {
                System.out.println(headerName);
                System.out.println(part.getHeader(headerName));
            }
            System.out.println("Size: ");
            System.out.println(part.getSize());
            part.write(part.getName() + "-down");
        }
 

 

전체다 가져오기: req.getParts()

한개만 가져오기: req.getPart(String name)
