8-Spring Boot ( 整合使用mybatis )

 1.pom文件引入依赖

 
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.4.2.RELEASE</version>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.21</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>  

2.创建User实体类

 
@Entity(name = "users")
public class User {
@Id
@GeneratedValue
private Integer id;
@Column
private String name;
@Column
private Integer age;
      // ..get/set方法
}  

3.创建UserDao

 
public interface UserDao extends JpaRepository<User, Integer> {
}  

4. 创建IndexController

 
@RestController
public class IndexController {
@Autowired
private UserDao userDao;
@RequestMapping("/index")
public String index(Integer id) {
User findUser = userDao.findOne(id);
System.out.println(findUser.getName());
return "success";
<
af11
span style="white-space:pre;"> }
}  

5. 启动项目

 
@ComponentScan(basePackages = { "com.itmayiedu" })
@EnableJpaRepositories(basePackages = "com.itmayiedu.dao")
@EnableAutoConfiguration
@EntityScan(basePackages = "com.itmayiedu.entity")
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
