springboot实现session拦截器供参考:
//session拦截器
@Component("sessionInterceptor")
public class SessionInterceptor extends HandlerInterceptorAdapter{
// 忽略的URL地址
private static final String[] IGNORE_URI = {"/login","/logintest"};
@Override
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler) throws Exception
{
SessionInfo session = (SessionInfo) request.getSession().getAttribute("session");
String requestURI = request.getRequestURI();
String contextPath = request.getContextPath();
contextPath = contextPath+"/";
for (int i = 0; i < IGNORE_URI.length; i++) {
// 忽略的url地址
if (requestURI.contains(IGNORE_URI[i]) || requestURI.equals(contextPath)) {
return true;
}
}
//如果session为空则提示未登录
if(!requestURI.contains(IGNORE_URI[i])&& null == session) {
String requestType = request.getHeader("X-Requested-With");
if(!BaseUtil.stringIsNull(requestType)){
if("XMLHttpRequest".equals(requestType)) {
throw new GenericException("session为空");
}
}
request.getRequestDispatcher("/WEB-INF/views/login/login.jsp").forward(request, response);
}
return true;
}
}
