前言

SpringBoot本身已经提供了依托于maven的Spring Initializr作为创建项目的快速方式，但是当前使用Maven创建SpringBoot项目更容易按照我们的要求对项目进行配置。

创建过程

**一、创建项目（什么快捷框架也不选）**  
    maven –>next –>next

**二、在main下新建webapp Package包**
**三、添加maven管理配置**
<packaging>war</packaging>
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.1.RELEASE</version>
</parent>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>1.3.2</version>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <scope>runtime</scope>
    </dependency>
    <dependency>
        <groupId>net.sf.json-lib</groupId>
        <artifactId>json-lib</artifactId>
        <version>2.4</version>
        <classifier>jdk15</classifier>
    </dependency>
</dependencies>
**四、打包配置**
<packaging>war</packaging>
<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <executions>
                <execution>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
**五、在java目录下新建层级com.basic.springbootmvn,新建Application.java作为入口类**
@SpringBootApplication
@MapperScan("com.basic.springbootmvn.Dao")//非常重要
@ImportResource(locations={
   "classpath:Mapper/*.xml"})
public class Application { 
    public static void main(String[] args) {
        SpringApplication.run(Application.class,args);
    }
}
**六、 在resource中新建application.yml**  
     添加如下配置
server:
  port: 8081
  tomcat:
    uri-encoding: utf-8
spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://192.168.38.128:3306/teststu
    username: root
    password: 1234
mybatis:
  typeAliasesPackage: com.basic.springbootmvn.Entity
  mapperLocations: classpath*:/Mapper/*.xml
**七、新建Entity、Dao、service、serviceImpl、Controller，在resource中新建Mapper 新建.xml文件**  
     和在Spring Initializr创建相同 详见：[https://blog.csdn.net/idomyway/article/details/80516848][https_blog.csdn.net_idomyway_article_details_80516848]
**八、运行配置**
     `Run/Debug configurations` 中添加`springboot` 配置名称和入口类即可运行
