springboot的項目搭建

1，new 一個project
2，常見項目名字
3，選擇

4，存放的位置

5，配置yml文件
server:
port: 8089

#修改項目訪問路徑

#鏈接池配置
spring:
datasource:
type:
driver: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost:3306/spring_boot_demo?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf8&useSSL=false

#mybatis配置
mybatis:
mapper-locations: mapping/*.xml
type-aliases-package: com.yunduan.demo2.entity

6，項目的結構
7，依賴配置

org.springframework.boot
spring-boot-starter-web

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>

    <!--mybatis 依賴-->
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>2.1.0</version>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>8.0.13</version>
    </dependency>
    <!-- 分頁插件 -->
    <dependency>
        <groupId>com.github.pagehelper</groupId>
        <artifactId>pagehelper-spring-boot-starter</artifactId>
        <version>1.2.3</version>
    </dependency>
    <!--連接池配置-->
    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>druid</artifactId>
        <version>1.0.31</version>
    </dependency>
    <!--log4j-->
    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.17</version>
    </dependency>
    8，在啓動類文件上面加@MapperScan註解

9，千萬要注意的是mapper和xml文件分開放
