Spring Boot - Any shortcuts for setting TaskExecutor?

Question

Just wanted to check in to see if anyone had a faster way to set the TaskExecutor for Spring MVC within spring boot (using auto configuration). This is what I have so far:<

Answer 1

One way to achieve this is to use Spring's ConcurrentTaskExceptor class. This class acts as adapter between Spring's TaskExecutor and JDK's Executor.

@Bean
protected WebMvcConfigurer webMvcConfigurer() {
    return new WebMvcConfigurerAdapter() {
        @Override
        public void configureAsyncSupport(AsyncSupportConfigurer configurer) {
            configurer.setTaskExecutor(new ConcurrentTaskExecutor(Executors.newFixedThreadPool(5)));
        }
    };
}

One problem with above is that you can't specify maximum pool size. But you can always create a new factory method, createThreadPool(int core, int max) to get you configurable thread pools.
