SpringBoot實(shí)現(xiàn)自定義線(xiàn)程池的方法

 更新時(shí)間：2023年11月14日 10:09:48   作者：huayang183  
這篇文章主要介紹了SpringBoot中的自定義線(xiàn)程池解析,實(shí)現(xiàn)自定義線(xiàn)程池重寫(xiě)spring默認(rèn)線(xiàn)程池的方式使用的時(shí)候,只需要加@Async注解就可以,不用去聲明線(xiàn)程池類(lèi),需要的朋友可以參考下

1. 自定義線(xiàn)程池

1.1 修改application.properties

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

1.2 線(xiàn)程池配置屬性類(lèi)TaskThreadPoolConfig .java

import org.springframework.boot.context.properties.ConfigurationProperties;
 
/**
 * 線(xiàn)程池配置屬性類(lèi)
 * 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 創(chuàng)建線(xiàn)程池 TaskExecutePool .java

/**
 * 創(chuàng)建線(xiàn)程池
 * Created by Fant.J.
 */
@Configuration
@EnableAsync
public class TaskExecutePool {
    @Autowired
    private TaskThreadPoolConfig config;
 
    @Bean
    public Executor myTaskAsyncPool() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        //核心線(xiàn)程池大小
        executor.setCorePoolSize(config.getCorePoolSize());
        //最大線(xiàn)程數(shù)
        executor.setMaxPoolSize(config.getMaxPoolSize());
        //隊(duì)列容量
        executor.setQueueCapacity(config.getQueueCapacity());
        //活躍時(shí)間
        executor.setKeepAliveSeconds(config.getKeepAliveSeconds());
        //線(xiàn)程名字前綴
        executor.setThreadNamePrefix("MyExecutor-");
 
        // setRejectedExecutionHandler：當(dāng)pool已經(jīng)達(dá)到max size的時(shí)候，如何處理新任務(wù)
        // CallerRunsPolicy：不在新線(xiàn)程中執(zhí)行任務(wù)，而是由調(diào)用者所在的線(xiàn)程來(lái)執(zhí)行
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        executor.initialize();
        return executor;
    }
}

1.4 創(chuàng)建線(xiàn)程任務(wù)

/**
 * Created by Fant.J.
 */
@Component
public class AsyncTask {
    protected final Logger logger = LoggerFactory.getLogger(this.getClass());
 
    @Async("myTaskAsyncPool")  //myTaskAsynPool即配置線(xiàn)程池的方法名，此處如果不寫(xiě)自定義線(xiàn)程池的方法名，會(huì)使用默認(rèn)的線(xiàn)程池
    public void doTask1(int i) throws InterruptedException{
        logger.info("Task"+i+" started.");
    }
}

1.5 修改啟動(dòng)類(lèi)

給啟動(dòng)類(lèi)添加注解

@EnableAsync
@EnableConfigurationProperties({TaskThreadPoolConfig.class} ) // 開(kāi)啟配置屬性支持

1.6 測(cè)試

    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. 配置默認(rèn)的線(xiàn)程池

我本人喜歡用這種方式的線(xiàn)程池，因?yàn)樯厦娴哪莻€(gè)線(xiàn)程池使用時(shí)候總要加注解@Async("myTaskAsyncPool")，而這種重寫(xiě)spring默認(rèn)線(xiàn)程池的方式使用的時(shí)候，只需要加@Async注解就可以，不用去聲明線(xiàn)程池類(lèi)。

2.1 獲取屬性配置類(lèi)

這個(gè)和上面的TaskThreadPoolConfig類(lèi)相同，這里不重復(fù)

2.2 NativeAsyncTaskExecutePool.java 裝配線(xiàn)程池

/**
 * 原生(Spring)異步任務(wù)線(xiàn)程池裝配類(lèi)
 * Created by Fant.J.
 */
@Slf4j
@Configuration
public class NativeAsyncTaskExecutePool implements AsyncConfigurer{
 
 
    //注入配置類(lèi)
    @Autowired
    TaskThreadPoolConfig config;
 
    @Override
    public Executor getAsyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        //核心線(xiàn)程池大小
        executor.setCorePoolSize(config.getCorePoolSize());
        //最大線(xiàn)程數(shù)
        executor.setMaxPoolSize(config.getMaxPoolSize());
        //隊(duì)列容量
        executor.setQueueCapacity(config.getQueueCapacity());
        //活躍時(shí)間
        executor.setKeepAliveSeconds(config.getKeepAliveSeconds());
        //線(xiàn)程名字前綴
        executor.setThreadNamePrefix("MyExecutor-");
 
        // setRejectedExecutionHandler：當(dāng)pool已經(jīng)達(dá)到max size的時(shí)候，如何處理新任務(wù)
        // CallerRunsPolicy：不在新線(xiàn)程中執(zhí)行任務(wù)，而是由調(diào)用者所在的線(xiàn)程來(lái)執(zhí)行
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        executor.initialize();
        return executor;
    }
 
 
    /**
     *  異步任務(wù)中異常處理
     * @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 線(xiàn)程任務(wù)類(lèi)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 測(cè)試

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