Springboot异步方法在同一线程中运行

之所以会发生这种情况,是因为您正在使用自己实例化的类上调用异步方法 new

TestAsyncClazz clazz = new TestAsyncClazz();
clazz.testAsyncMethod();

这只会以您期望的方式在Springbean上工作——换句话说,不要实例化 TestAsyncClazz 你自己定义该类的Springbean实例,将该bean自动连接到控制器中,然后调用该bean上的方法。

例子:

@Configuration
@EnableAsync
public class AsyncConfig {

    @Bean
    public Executor asyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(5);
        executor.setMaxPoolSize(5);
        executor.setQueueCapacity(500);
        executor.setThreadNamePrefix("Async Process-");
        executor.initialize();
        return executor;
    }

    // Define a Spring bean of type TestAsyncClazz
    @Bean
    public TestAsyncClazz testAsyncClazz() {
        return new TestAsyncClazz();
    }
}

@Controller
public class MyController {

    // Inject the bean here
    @Autowired 
    private TestAsyncClazz testAsyncClass;

    @GetMapping("/test/async")
    public void testAsync() {
        System.err.println("Thread in controller: " +
                Thread.currentThread().getName());

        // Use the bean instead of instantiating the class yourself
        testAsyncClass.testAsyncMethod();
    }
}
