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
@EnjsableAsync @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 asyncTaspythonk; @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."); }
