Thread Demo

实现类

import org.springframework.core.task.TaskExecutor;

public class DemoBOImpl 
{
    // 线程池
    @Resource(name = "taskExecutor")
    private TaskExecutor taskExecutor;

    @Override
    public void executeThread() throws Exception {
        // 线程池控制
        taskExecutor.execute(new DemoThread());
    }
}

线程类

public class DemoThread implements Runnable 
{
    public DemoThread() {
    }

    @Override
    public void run() {
        try {
            // do things
        } catch (Exception e) {
        }
    }
}
