[java] Spring Security / SpringMVC에서 인증 된 사용자를 수동으로 설정하는 방법

나는 당신과 얼마 전에 같은 문제를 겪었습니다. 세부 사항을 기억할 수 없지만 다음 코드는 나를 위해 일했습니다. 이 코드는 Spring Webflow 흐름 내에서 사용되므로 RequestContext 및 ExternalContext 클래스가 사용됩니다. 그러나 가장 관련성이 높은 부분은 doAutoLogin 메서드입니다.

public String registerUser(UserRegistrationFormBean userRegistrationFormBean,
                           RequestContext requestContext,
                           ExternalContext externalContext) {

    try {
        Locale userLocale = requestContext.getExternalContext().getLocale();
        this.userService.createNewUser(userRegistrationFormBean, userLocale, Constants.SYSTEM_USER_ID);
        String emailAddress = userRegistrationFormBean.getChooseEmailAddressFormBean().getEmailAddress();
        String password = userRegistrationFormBean.getChoosePasswordFormBean().getPassword();
        doAutoLogin(emailAddress, password, (HttpServletRequest) externalContext.getNativeRequest());
        return "success";

    } catch (EmailAddressNotUniqueException e) {
        MessageResolver messageResolvable 
                = new MessageBuilder().error()
                                      .source(UserRegistrationFormBean.PROPERTYNAME_EMAIL_ADDRESS)
                                      .code("userRegistration.emailAddress.not.unique")
                                      .build();
        requestContext.getMessageContext().addMessage(messageResolvable);
        return "error";
    }

}


private void doAutoLogin(String username, String password, HttpServletRequest request) {

    try {
        // Must be called from request filtered by Spring Security, otherwise SecurityContextHolder is not updated
        UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(username, password);
        token.setDetails(new WebAuthenticationDetails(request));
        Authentication authentication = this.authenticationProvider.authenticate(token);
        logger.debug("Logging in with [{}]", authentication.getPrincipal());
        SecurityContextHolder.getContext().setAuthentication(authentication);
    } catch (Exception e) {
        SecurityContextHolder.getContext().setAuthentication(null);
        logger.error("Failure in autoLogin", e);
    }

}

public void login(HttpServletRequest request, String userName, String password)
{

    UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(userName, password);

    // Authenticate the user
    Authentication authentication = authenticationManager.authenticate(authRequest);
    SecurityContext securityContext = SecurityContextHolder.getContext();
    securityContext.setAuthentication(authentication);

    // Create a new session and add the security context.
    HttpSession session = request.getSession(true);
    session.setAttribute("SPRING_SECURITY_CONTEXT", securityContext);
}
