springboot配置

idea导入项目的过程：
直接导入pom文件即可，直接import project即可

springboot快速入门：

导入坐标：
springBoot要求，项目要继承springBoot的起步一拉spring-boot-starter-parent

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.1.RELEASE</version>
    </parent>

SpringBoot要集成SpringMVC进行Controller的开发，所以项目要导入web的启动依赖

<dependencies>
        <!--web功能的起步依赖-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>

编写springboot的引导类

package com.itheima;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class MySpringBootApplication {
    public static void main(String[] args) {
        SpringApplication.run(MySpringBootApplication.class);
    }
}

@SpringBootApplication：标志springboot的引导类

springboot的热部署
实现springboot的热部署只需要在pom下添加一个坐标：

-- ----------------------------- Table structure for user -- ---------------------------
DROP TABLE IF EXISTS user; CREATE TABLE user ( id int(11) NOT NULL AUTO_INCREMENT, username varchar(50) DEFAULT NULL, password varchar(50) DEFAULT NULL, name varchar(50) DEFAULT NULL, PRIMARY KEY (id) ) ENGINE=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=utf8;

-- ----------------------------- Records of user -- ---------------------------
INSERT INTO user VALUES ('1', 'zhangsan', '123', '张三'); INSERT INTO user VALUES ('2', 'lisi', '123', '李四');
