創建Spring web項目

從零開始創建Spring Web項目

通過Maven創建Java Web項目，主要流程

Jar包依賴

web.xml添加Spring 配置

測試代碼

/**
 * 定義測試方法
 */
@Component
public class AsyncTask {

    public void exec() throws Exception{
        System.out.println("準備睡覺");
        Thread.sleep(1000);
        System.out.println("醒了");
    }
}

/**
 * JUnit測試
 */
public class AsyncTaskTest extends AbstractTest {

    @Autowired
    private AsyncTask asyncTask;

    @Test
    public void testExec() throws Exception {
        asyncTask.exec();
    }
}

測試結果

準備睡覺
醒了
