一.創建spring boot項目
1.File->New->Project
2.選擇 Spring Initializr ，然后選擇默認的 url 點擊【Next】：
3.修改項目信息
4.選擇項目的模板
5、填寫Project name 和項目的位置，然后點擊Finish。
點擊完成后生產的代碼結構圖：
二：配置pom文件
因為需要集成Mybatis插入，所以需要在pom.xml中加上依賴包
所以最后的pom.xml文件內容如下：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<overwrite>true</overwrite>
<verbose>true</verbose>
</configuration>
</plugin>
</plugins>
</build>
</project>
其中
<!-- mybatis generator 自動生成代碼插件 -->
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<configuration>
<configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile>
<overwrite>true</overwrite>
<verbose>true</verbose>
</configuration>
</plugin>
是mybatis generator 自動生成代碼插件配置文件的地址；
三：配置mybatis
1.添加mybatis generator 自動生成代碼插件配置文件
在resources文件加下添加generator文件夾，並創建generatorConfig.xml文件
內容如下：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration PUBLIC
"-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
<!-- 數據庫驅動:選擇你的本地硬盤上面的數據庫驅動包-->
<classPathEntry location="D:\mysql-connector-java-5.1.46.jar"/>
<context id="DB2Tables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressDate" value="true"/>
<!-- 是否去除自動生成的注釋 true：是 ： false:否 -->
<property name="suppressAllComments" value="true"/>
</commentGenerator>
<!--數據庫鏈接URL，用戶名、密碼 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost:3306/ygop_eps_commodity" userId="test" password="test">
</jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false"/>
</javaTypeResolver>
<!-- 生成模型的包名和位置-->
<javaModelGenerator targetPackage="com.example.springbatis.model.entities" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
<property name="trimStrings" value="true"/>
</javaModelGenerator>
<!-- 生成映射文件的包名和位置-->
<sqlMapGenerator targetPackage="mybatis/mapper/auto" targetProject="src/main/resources">
<property name="enableSubPackages" value="true"/>
</sqlMapGenerator>
<!-- 生成DAO的包名和位置-->
<javaClientGenerator type="XMLMAPPER" targetPackage="com.example.springbatis.dto.auto" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<!-- 要生成的表 tableName是數據庫中的表名或視圖名 domainObjectName是實體類名-->
<table tableName="commodity" domainObjectName="Commodity" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table>
</context>
</generatorConfiguration>
四.配置application.yml
server:
port: 8089
spring:
datasource:
mame:
type: com.alibaba.druid.pool.DruidDataSource
url: jdbc:mysql://localhost:3306/ygop_eps_commodity
username: test
password: test
driver-class-name: com.mysql.jdbc.Driver
filters: stat
maxActive: 20
initialSize: 1
maxWait: 60000
minIdle: 1
timeBetweenEvictionRunsMillis: 60000
minEvictableIdleTimeMillis: 300000
validationQuery: select 'x'
testWhileIdle: true
testOnBorrow: false
testOnReturn: false
poolPreparedStatements: true
maxOpenPreparedStatements: 20
#Mybatis配置
mybatis:
mapper-locations: classpath:mybatis/mapper/**/*.xml
type-aliases-package: ygop.o2o.jdq.service.model.entities
五：設置build自動生成代碼
1.Run->Edit Configurations
點擊加好+
然后配置mybatis-generator信息
店家Apply 和OK最后在主界面的右上角會有一個
；
2.自動生成代碼
生成代碼結構圖：
到這里spring boot+mybatis搭建項目就已經完成了；
六：運行程序
1.添加注解
在SpringbatisApplication中添加注解
將mapper注入到Spring中
@MapperScan("com.example.springbatis.dto")
2.創建Controller
3.運行：
