springboot2 默认数据库连接池HikariCP

1.Springboot2默认数据库连接池选择了HikariCP为何选择HikariCP

    理由一、代码量

    理由二、口碑

    理由三、速度

    理由四、稳定性

    理由五、可靠性

2.druid对数据源进行了监控，但是我们知道sharding-jdbc, mycat等都可以监控。

3.我们这里给出一个例子看看怎么使用以及速度如何

4.环境：jdk8,springboot 2.0.2release.

@RestController
@Slf4j
public class UserController {
	
	@Autowired
	private UserService UserService;
	
	@RequestMapping("/user/{id}")
	public User getById(@PathVariable Long id) {
		log.info("id={}",id);
		return UserService.getById(id);
	}
}

logging.level.root=info
