SpringBoot测试类

POM添加依赖

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.4.RELEASE</version>
    </parent>

　　

 <!--测试包-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>

　　测试类编写

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {SpringAsyncConfig.class})
public class SpringbootTest {
    @Autowired
    private SpringAsyncConfig SpringAsyncConfig;
 
    @Test
    public void NacosTest() {
 
         SpringAsyncConfig.asyncMethodWithReturnType();

    }
}

　　依赖类

 

@Configuration
@EnableAsync
public class SpringAsyncConfig {

    @Bean("mytaskExecutor")
    public TaskExecutor taskExecutor(){
        ThreadPoolTaskExecutor threadPoolTaskExecutor = new ThreadPoolTaskExecutor();
        threadPoolTaskExecutor.setThreadNamePrefix("taskExecutor");
        threadPoolTaskExecutor.setCorePoolSize(10);
        threadPoolTaskExecutor.setMaxPoolSize(30);
        threadPoolTaskExecutor.setQueueCapacity(100);
        threadPoolTaskExecutor.afterPropertiesSet();
        return threadPoolTaskExecutor;
    }




    @Async  //标注使用
    public void asyncMethodWithVoidReturnType() {
        System.out.println("Execute method asynchronously. "
                + Thread.currentThread().getName());
    }


    @Async
    public Future<String> asyncMethodWithReturnType() {
        System.out.println("Execute method asynchronously - "
                + Thread.currentThread().getName());
        try {
            Thread.sleep(5000);
            return new AsyncResult<String>("hello world !!!!");
        } catch (InterruptedException e) {
            //
        }

        return null;
    }


    @Test
    public void run(){

    }

    public static void main(String[] args) {
        AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(SpringAsyncConfig.class);

        SpringAsyncConfig bean = (SpringAsyncConfig) context.getBean("springAsyncConfig");

        bean.asyncMethodWithReturnType();

        Future<String> str =   bean.asyncMethodWithReturnType();

        System.out.println(str);

        System.out.println("121");
    }

}
