MockMvc security filters causes FileUploadException: the request was rejected because no multipart boundary was found [SPR-12114]

Andres A opened SPR-12114 and commented

When testing a controller using MockMvc, file upload works as expected, but when adding the Spring Security filter chain, the request fails with:

Even if the filter is a pass through:

public class UserFilter extends GenericFilterBean {

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        HttpServletRequest httpServletRequest = (HttpServletRequest) request;
        HttpServletResponse httpServletResponse = (HttpServletResponse) response;
        if (validUser(request)) {
            chain.doFilter(request, response);
        } else {
            httpServletResponse.setStatus(403);
        }
    }
}

XML:

<bean id="springSecurityFilterChain" class="org.springframework.security.web.FilterChainProxy">
        <sec:filter-chain-map path-type="ant">
            <sec:filter-chain pattern="/api/**" filters="userFilter"/>
        </sec:filter-chain-map>
    </bean>

What I mean by adding the security filter chain is using this:

this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).addFilters(this.springSecurityFilterChain).build();

... instead of just this:

this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();

Rossen Stoyanchev commented

When using MockMvc to perform a file upload, the prepared MockMultipartHttpServletRequest represents a parsed multipart request and hence there should be no parsing. However, since Spring Security wraps the request, the DispatcherServlet incorrectly tries to parse as a multipart request. Even if this doesn't affect production, it seems safe to make a change in DispatcherServlet checkMultipart to unwrap the request as is done in cleanupMultipart.
