如何快速的搭建一个springBoot+mybatis框架

1.打开idea编译器，新建一个项目

 2.选择Spring Initializr 勾选Default,完成之后点击【Next】

3.创建项目的文件目录结构以及选择jdk版本信息，设置完成后点击【Next】

4.选择项目所需要的依赖，在Web里面勾选Spring Web

根据自己需要添加数据库和其他依赖

5.修改项目名称，项目存放路径，点击【finish】

6.创建完成之后需要保持网络良好，因为需要加载刚才所选择的依赖（下载依赖可能需要很长时间，一定要在网络良好的情况下载，并且耐心等待） pom.xml文件是用来添加依赖的地方

7.完善springboot+mybatis文件结构 在所示目录下创建文件夹

8.创建配置文件并进行配置

创建这两个yml文件 Application-.yml文件中所需配置代码：

server:
  port: 9900

spring:
  #配置
  datasource:
    druid:
      tdw:
        type: com.alibaba.druid.pool.DruidDataSource
        driver-class-name: com.mysql.cj.jdbc.Driver
        url: jdbc:mysql://192.168.1.177:3306/tdw_test?useUnicode=true&characterEncoding=utf8&useSSL=true&serverTimezone=Asia/Shanghai
        username: root
        password: zdzc@2017

schedules: 0/10 * * * * ?

我这边数据源采用配置类，方便以后可能有多数据源（如有多个，可以用多个这样的配置类）

注解@MapperScan是用来扫描dao层mapper类
需要配置对应的model类和xml文件放置位置

@ConfigurationProperties("spring.datasource.druid.tdw") 配置对应的数据源

private static final String MAPPER_LOCATIONS = "classpath*:com/zenchn/demo/dao/mapper/*.xml";（注意：因为我的xml文件不在resourse目录里，所以要加classpath后面要加*号
在pom文件中加入

<build>
    <!--配置Maven 对resource文件 过滤 -->
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
                <include>*.yml</include>
            </includes>
            <filtering>false</filtering>
        </resource>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
                <include>*.yml</include>
            </includes>
            <filtering>false</filtering>
        </resource>
    </resources>
    <plugins>
可以找到对应的xml文件，不然启动会报错，如果不想加，可以将xml配置文件放到resourse目录）

private static final String TYPE_ALIASES_PACKAGE ="com.zenchn.demo.model";

在启动类上添加这三个注解
@EnableTransactionManagement 开启事务支持
@SpringBootApplication
@EnableScheduling 开启定时任务注解支持

springBoot中yml配置文件如果要支持中文注释，必须转化为utf-8格式，不然启动会报错

我的poml依赖
