RequestContextHolder.getRequestAttributes() is null sometimes

Question

In my Java Spring project I use

HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder
                                         .getRequestAttributes())
                                         .getRequest();

which defined in a static method to get request and get some session attributes. spring-RequestContextListener is already exist in my web.xml. The question is when some single thread invoke that, everything is fine for now.

But when using java8 parallelStream, RequestContextHolder.getRequestAttributes() can be null sometimes and I do not know why.

Answer 1

Is your project spring or spring boot? if it is spring boot, expose a bean with either RequestContextListener or RequestContextFilter

@Bean
  public RequestContextListener requestContextListener() {
    return new RequestContextListener();
  }

also make sure you don't have any @Configuration classes anotated with @EnableWebMvc. this will remove spring boot autoconfiguration cababilities.
