java - Spring @Scheduler并行运行

我有以下3个类(class):

成分A

package mytest.spring.test.spring;

import org.apache.log4j.Logger;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@Component
public class ComponentA {

    Logger log = Logger.getLogger(ComponentB.class);

    @Scheduled(fixedRate=2000)
    public void sayHello() {
        for(int i=1 ; i<=5 ; i++) {
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            log.info("Hello from ComponentA " + i);
        }
    }
}

组分B

package mytest.spring.test.spring;

import org.apache.log4j.Logger;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@Component
public class ComponentB {

    Logger log = Logger.getLogger(ComponentB.class);

    @Scheduled(fixedRate=2000)
    public void sayHello() {
        for(int i=1 ; i<=3 ; i++) {
            try {
                Thread.sleep(2000);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            log.info("Hello from ComponentB " + i);
        }
    }
}

我的应用程序

package mytest.spring.test.spring;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling
public class MyApplication {

    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }
}

当我执行它时，我得到以下输出:

Hello from ComponentA 1
Hello from ComponentA 2
Hello from ComponentA 3
Hello from ComponentA 4
Hello from ComponentA 5
Hello from ComponentB 1
Hello from ComponentB 2
Hello from ComponentB 3
Hello from ComponentA 1
Hello from ComponentA 2
Hello from ComponentA 3
Hello from ComponentA 4
Hello from ComponentA 5
Hello from ComponentB 1
Hello from ComponentB 2
Hello from ComponentB 3
...

我需要2个Scheduled方法并行运行，根据我得到的输出，这显然不是问题。我读到应该可以为@Schedule批注提供一个自定义TaskExecutor，用它可以定义我们想要多少个线程...

我对吗 ？我找不到如何提供此信息。

The documentation明确指出:
