SpringBoot实现自定义线程池的方法

 更新时间：2023年11月14日 10:09:48   作者：huayang183  
这篇文章主要介绍了SpringBoot中的自定义线程池解析,实现自定义线程池重写spring默认线程池的方式使用的时候,只需要加@Async注解就可以,不用去声明线程池类,需要的朋友可以参考下

1. 自定义线程池

1.1 修改application.properties

task.pool.corePoolSize=20task.pool.maxPoolSize=40task.pool.keepAliveSeconds=300task.pool.queueCapacity=50

1.2 线程池配置属性类TaskThreadPoolConfig .java

import org.springframework.boot.context.properties.ConfigurationProperties;
 
/**
 * 线程池配置属性类
 * Created by Fant.J.
 */
@ConfigurationProperties(prefix = "task.pool")
public class TaskThreadPoolConfig {
    private int corePoolSize;
 
    private int maxPoolSize;
 
    private int keepAliveSeconds;
 
    private int queueCapacity;
    ...getter and setter methods...
}

1.3 创建线程池 TaskExecutePool .java

/**
 * 创建线程池
 * Created by Fant.J.
 */
@Configuration
@EnableAsync
public class TaskExecutePool {
    @Autowired
    private TaskThreadPoolConfig config;
 
    @Bean
    public Executor myTaskAsyncPool() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        //核心线程池大小
        executor.setCorePoolSize(config.getCorePoolSize());
        //最大线程数
        executor.setMaxPoolSize(config.getMaxPoolSize());
        //队列容量
        executor.setQueueCapacity(config.getQueueCapacity());
        //活跃时间
        executor.setKeepAliveSeconds(config.getKeepAliveSeconds());
        //线程名字前缀
        executor.setThreadNamePrefix("MyExecutor-");
 
        // setRejectedExecutionHandler：当pool已经达到max size的时候，如何处理新任务
        // CallerRunsPolicy：不在新线程中执行任务，而是由调用者所在的线程来执行
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        executor.initialize();
        return executor;
    }
}

1.4 创建线程任务

/**
 * Created by Fant.J.
 */
@Component
public class AsyncTask {
    protected final Logger logger = LoggerFactory.getLogger(this.getClass());
 
    @Async("myTaskAsyncPool")  //myTaskAsynPool即配置线程池的方法名，此处如果不写自定义线程池的方法名，会使用默认的线程池
    public void doTask1(int i) throws InterruptedException{
        logger.info("Task"+i+" started.");
    }
}

1.5 修改启动类

给启动类添加注解

@EnableAsync
@EnableConfigurationProperties({TaskThreadPoolConfig.class} ) // 开启配置属性支持

1.6 测试

    protected final Logger logger = LoggerFactory.getLogger(this.getClass());
    @Autowired
    private AsyncTask asyncTask;
 
    @Test
    public void AsyncTaskTest() throws InterruptedException, ExecutionException {
 
        for (int i = 0; i < 100; i++) {
            asyncTask.doTask1(i);
        }
        logger.info("All tasks finished.");
    }

2. 配置默认的线程池

我本人喜欢用这种方式的线程池，因为上面的那个线程池使用时候总要加注解@Async("myTaskAsyncPool")，而这种重写spring默认线程池的方式使用的时候，只需要加@Async注解就可以，不用去声明线程池类。

2.1 获取属性配置类

这个和上面的TaskThreadPoolConfig类相同，这里不重复

2.2 NativeAsyncTaskExecutePool.java 装配线程池

/**
 * 原生(Spring)异步任务线程池装配类
 * Created by Fant.J.
 */
@Slf4j
@Configuration
public class NativeAsyncTaskExecutePool implements AsyncConfigurer{
 
 
    //注入配置类
    @Autowired
    TaskThreadPoolConfig config;
 
    @Override
    public Executor getAsyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        //核心线程池大小
        executor.setCorePoolSize(config.getCorePoolSize());
        //最大线程数
        executor.setMaxPoolSize(config.getMaxPoolSize());
        //队列容量
        executor.setQueueCapacity(config.getQueueCapacity());
        //活跃时间
        executor.setKeepAliveSeconds(config.getKeepAliveSeconds());
        //线程名字前缀
        executor.setThreadNamePrefix("MyExecutor-");
 
        // setRejectedExecutionHandler：当pool已经达到max size的时候，如何处理新任务
        // CallerRunsPolicy：不在新线程中执行任务，而是由调用者所在的线程来执行
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        executor.initialize();
        return executor;
    }
 
 
    /**
     *  异步任务中异常处理
     * @return
     */
    @Override
    public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() {
        return new AsyncUncaughtExceptionHandler() {
 
            @Override
            public void handleUncaughtException(Throwable arg0, Method arg1, Object... arg2) {
                log.error("=========================="+arg0.getMessage()+"=======================", arg0);
                log.error("exception method:"+arg1.getName());
            }
        };
    }
}

2.3 线程任务类AsyncTask .java

@Component
public class AsyncTask {
    protected final Logger logger = LoggerFactory.getLogger(this.getClass());
 
    @Async
    public void doTask2(int i) throws InterruptedException{
        logger.info("Task2-Native"+i+" started.");
    }
}

2.4 测试

    @Test
    public void AsyncTaskNativeTest() throws InterruptedException, ExecutionException {
 
        for (int i = 0; i < 100; i++) {
            asyncTask.doTask2(i);
        }
 
        logger.info("All tasks finished.");
    }
