> 此 demo 主要演示了 Spring Boot 如何使用原生提供的异步任务支持,实现异步执行任务。 | |||||
### 1.开发步骤 | |||||
#### 1.1.添加依赖 | |||||
```xml | |||||
<dependencies> | |||||
<dependency> | |||||
<groupId>org.springframework.boot</groupId> | |||||
<artifactId>spring-boot-starter</artifactId> | |||||
</dependency> | |||||
<dependency> | |||||
<groupId>org.springframework.boot</groupId> | |||||

<dependency> | |||||
<groupId>org.projectlombok</groupId> | |||||
<artifactId>lombok</artifactId> | |||||
<optional>true</optional> | |||||
</dependency> | |||||
</dependencies> | |||||
``` | |||||
#### 1.2.增加异步线程池的配置 | |||||
> 注意:如果不配置的话,会使用默认的线程池配置 | |||||
```yaml | |||||
spring: | |||||
task: | |||||
execution: | |||||
pool: | |||||
# 最大线程数 | |||||
max-size: 16 | |||||
# 核心线程数 | |||||
core-size: 16 | |||||
# 存活时间 | |||||
keep-alive: 10s | |||||
# 队列大小 | |||||
queue-capacity: 100 | |||||
# 是否允许核心线程超时 | |||||
allow-core-thread-timeout: true | |||||
# 线程名称前缀 | |||||
thread-name-prefix: async-task- | |||||
``` | |||||
#### 1.3.同步、异步任务模拟 | |||||
> 1. 异步方法的返回值,需要指定为:`java.util.concurrent.Future`,`org.springframework.util.concurrent.ListenableFuture`,`java.util.concurrent.CompletableFuture` | |||||
> 2. 方法上标记 `@Async` | |||||
```java | |||||
@Component | |||||
@Slf4j | |||||
public class MockTaskFactory { | |||||
/** | |||||
* 模拟5秒的异步任务 | |||||
*/ | |||||
@Async | |||||
public CompletableFuture<Boolean> asyncTask1() throws InterruptedException { | |||||
doTask("asyncTask1", 5); | |||||
return CompletableFuture.completedFuture(Boolean.TRUE); | |||||
} | |||||
/** | |||||
* 模拟2秒的异步任务 | |||||
*/ | |||||
@Async | |||||
public CompletableFuture<Boolean> asyncTask2() throws InterruptedException { | |||||
doTask("asyncTask2", 2); | |||||
return CompletableFuture.completedFuture(Boolean.TRUE); | |||||
} | |||||
/** | |||||
* 模拟3秒的异步任务 | |||||
*/ | |||||
@Async | |||||
public CompletableFuture<Boolean> asyncTask3() throws InterruptedException { | |||||
doTask("asyncTask3", 3); | |||||
return CompletableFuture.completedFuture(Boolean.TRUE); | |||||
} | |||||
/** | |||||
* 模拟5秒的同步任务 | |||||
*/ | |||||
public void task1() throws InterruptedException { | |||||
doTask("task1", 5); | |||||
} | |||||
/** | |||||
* 模拟2秒的同步任务 | |||||
*/ | |||||
public void task2() throws InterruptedException { | |||||
doTask("task2", 2); | |||||
} | |||||
/** | |||||
* 模拟3秒的同步任务 | |||||
*/ | |||||
public void task3() throws InterruptedException { | |||||
doTask("task3", 3); | |||||
} | |||||
private void doTask(String taskName, Integer time) throws InterruptedException { | |||||
log.info("{}开始执行,当前线程名称【{}】", taskName, Thread.currentThread().getName()); | |||||
TimeUnit.SECONDS.sleep(time); | |||||
log.info("{}执行成功,当前线程名称【{}】", taskName, Thread.currentThread().getName()); | |||||
} | |||||
} | |||||
``` | |||||
#### 1.4.在启动类上增加注解 `@EnableAsync` | |||||
```java | |||||
@EnableAsync | |||||
@SpringBootApplication | |||||
public class AsyncApplication { | |||||
public static void main(String[] args) { | |||||
SpringApplication.run(AsyncApplication.class, args); | |||||
} | |||||
} | |||||
``` | |||||
### 2.测试 | |||||
#### 2.1.编写测试代码 | |||||
```java | |||||
@Slf4j | |||||
@SpringBootTest | |||||
@DisplayName("异步化测试") | |||||
public class MockTaskFactoryTest { | |||||
@Autowired | |||||

@Test | |||||
@DisplayName("异步任务") | |||||
public void asyncTaskTest() throws InterruptedException, ExecutionException { | |||||
long start = System.currentTimeMillis(); | |||||
CompletableFuture<Boolean> asyncResult1 = task.asyncTask1(); | |||||
CompletableFuture<Boolean> asyncResult2 = task.asyncTask2(); | |||||
CompletableFuture<Boolean> asyncResult3 = task.asyncTask3(); | |||||
CompletableFuture<Void> allResult = CompletableFuture.allOf(asyncResult1, asyncResult2, asyncResult3); | |||||
// 调用 get() 阻塞主线程 | |||||
allResult.get(); | |||||
long end = System.currentTimeMillis(); | |||||
log.info("异步任务全部执行结束,总耗时:{} 毫秒", (end - start)); | |||||
} | |||||
/** | |||||
* 测试同步任务 | |||||
*/ | |||||
@Test | |||||
@DisplayName("同步任务") | |||||
public void taskTest() throws InterruptedException { | |||||
long start = System.currentTimeMillis(); | |||||
task.task1(); | |||||
task.task2(); | |||||
task.task3(); | |||||
long end = System.currentTimeMillis(); | |||||
log.info("同步任务全部执行结束,总耗时:{} 毫秒", (end - start)); | |||||
} | |||||
} | |||||
``` | |||||
#### 2.2运行结果 | |||||
