+### 14.2. 定位main应用类
+
+我们通常建议你将main应用类放在位于其他类上面的根包（root package）中。通常使用`@EnableAutoConfiguration`注解你的main类，并且暗地里为某些项定义了一个基础“search package”。例如，如果你正在编写一个JPA应用，被`@EnableAutoConfiguration`注解的类所在包将被用来搜索`@Entity`项。
+
+使用根包允许你使用`@ComponentScan`注解而不需要定义一个`basePackage`属性。如果main类位于根包中，你也可以使用`@SpringBootApplication`注解。
+
+下面是一个典型的结构：
+```shell
+com
+ +- example
+     +- myproject
+         +- Application.java
+         |
+         +- domain
+         |   +- Customer.java
+         |   +- CustomerRepository.java
+         |
+         +- service
+         |   +- CustomerService.java
+         |
+         +- web
+             +- CustomerController.java
+```
+`Application.java`文件将声明`main`方法，还有基本的`@Configuration`。
+```java
+package com.example.myproject;
+
+import org.springframework.boot.SpringApplication;
+import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
+import org.springframework.context.annotation.ComponentScan;
+import org.springframework.context.annotation.Configuration;
+
+@Configuration
+@EnableAutoConfiguration
+@ComponentScan
+public class Application {
+
+    public static void main(String[] args) {
+        SpringApplication.run(Application.class, args);
+    }
+
+}
+```
