Spring Boot

测试用例

https://docs.spring.io/spring-boot/reference/testing/index.html

• spring boot test

import org.junit.Test;  
import org.junit.runner.RunWith;  
import org.springframework.boot.test.context.SpringBootTest;  
import org.springframework.test.context.junit4.SpringRunner;  
  
@RunWith(SpringRunner.class)  
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment._RANDOM_PORT_, classes = AppRun.class)  
public class ApiTest {  

    @Test  
    public void test(){  
        System._out_.println("---------测试-----------");  
        System._out_.println("---------测试结束-----------");  
    }  
  

}

线程池

//注入线程池

@Resource  
ThreadPoolTaskExecutor threadPoolTaskExecutor;

var completableFuture1 = CompletableFuture._supplyAsync_(() -> {  
// 处理任务  
return true;  
}, threadPoolTaskExecutor);  
_//等待5s_  
var res = completableFuture1.get(5,TimeUnit._SECONDS_);

启动后执行任务

import lombok.extern.slf4j.Slf4j;  
import org.springframework.boot.ApplicationArguments;  
import org.springframework.boot.ApplicationRunner;  
import org.springframework.core.annotation.Order;  
import org.springframework.stereotype.Component;  
  
  
@Component  
@Order(1)  
@Slf4j  
public class AppInitHandler implements ApplicationRunner {  
  
  
   @Override  
   public void run(ApplicationArguments args) throws Exception {  
      _log_.info("执行初始化程序开始");  
  
      doRun();  
      _log_.info("执行初始化程序结束");  
  
   }  
  
   private void doRun() {  
      _log_.info("执行初始化程序");  
  
   }  
}
