Spring Boot - 设置 TaskExecutor 的任何快捷方式? [英] Spring Boot - Any shortcuts for setting TaskExecutor?

问题描述

只是想签入看看是否有人有更快的方法在 spring 启动中为 Spring MVC 设置 TaskExecutor(使用自动配置).这是我目前所拥有的:

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:

@Bean
protected ThreadPoolTaskExecutor mvcTaskExecutor() {
    ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
    executor.setThreadNamePrefix("my-mvc-task-executor-");
    executor.setCorePoolSize(5);
    executor.setMaxPoolSize(200);
    return executor;
}

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

有没有人有更好/更快的方法来做到这一点?

Does anyone have a better/faster way to do this?

推荐答案

实现此目的的一种方法是使用 Spring 的 ConcurrentTaskExceptor 类.该类充当 Spring 的 TaskExecutor 和 JDK 的 Executor 之间的适配器.

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)));
        }
    };
}

上面的一个问题是您无法指定最大池大小.但是你总是可以创建一个新的工厂方法，createThreadPool(int core, int max) 来获得可配置的线程池.

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.
