### 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  
![70][]

**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
